New Trends for Application Interoperability in Romania

New Trends for Application Interoperability in Romania HEALTH VERTICAL MARKET Silviu Cojocaru PhD, Associate Professor, Faculty of Business and Administration, University of Bucharest, [emailprotected] Camelia Cojocaru PhD, Associate Professor, Faculty of Business and Administration, University of Bucharest, [emailprotected]   1. Introduction The Internet’s development has fundamentally affected the architecture of informatics management systems, causing substantial changes in the way that this category of solutions is distributed and reached. This considering, one could say that gaining access to economical applications through a simple Web browser came as a necessity in a world that is characterized by dynamism and by the globalization of economical phenomena [Aamodt, 1996]. So, in the 90s, the main trend in application development was offering support and accessibility – for computers that had an internet connection – to a wide range of informational resources (databases and more) and applications. The testimony for this is the multitude of languages and technologies that allow the easy development of database exploitation applications through a simple Web browser. This is why scripting languages that run on servers (ASP and its follower ASP.Net; PHP; JSP etc.), are now mature technologies, that of fer the possibility of developing complex Web technologies. This technologies’ existence has caused changes in informational necessities and in the equipments users need. Nowadays internet connections are available not only to computers, but also to a multitude of equipment such as mobile phones and other hand-held devices. Considering these necessities, creating a universal language became a dire need [McAfee,2005]. XML is the answer to these requests, and is a new stage in the informational age, easing the data exchange between different equipments. Beside the possibility of transferring data onto these heterogeneous platforms there was also the need of creating a way of communication between them. The answer to these priorities is the Web Services technology, which is now the most efficient way of cross-application Internet communication. 2. Literature review Web services are a standardized way of distributing Internet applications and fundamental technologies that are at the basis of this network. Also, web services offer the possibility of interconnecting a wide range of applications, which are available on different platforms and in several worldwide locations. One could say that Web technologies became an Esperanto of application communication, as the new technology opens the gate towards a new age dominated by intelligent applications that make smart decisions and Internet searches, as a basis for well-balanced decisions [Agosta,2000]. Therefore, supposing that we wish to build an expert system that manages a share portfolio, we need to keep in mind that such a system cannot function without constant market quotation updates. Plus, making an optimal decision for selling or buying is a matter of minutes, and this highly influences the efficiency of the system. If a decade ago this system was very complicated due to the lack of efficient means of cross application communication, after the development of Web applications, it became much easier. One would have to develop the classic portfolio management expert and then the link to the outside world would be this paper’s technology. The data containing the quotations will be transmitted via Internet through a web service developed by the stock market. By using the functions and procedures exposed by this Web services, the right parameters can be transmitted, and the stock market informational system will return the requested information. Plus, all of the exposed functions of the stock market system will become a part of the developed applications, and will be called for as similarly developed procedures. You will be able to schedule the automatic checking of stock market quotations and the permanent update of the local database. Things could move even further, with the possibility of inclosing a Web service for the brokerage society that would allow the expert system to not only makes the optimal choice but to implement the decision taken. This example shows how optimal communication automation actually works and how human intervention becomes unnecessary. This has a decisive role in eliminating intentional and non-intentional human errors from the entire process (Jacobides,2000). 3. Service Oriented Architecture XML or eXtended Markup Language is the basis for all of the elements behind the Web Services technologies. Considering the independence from the platform, XML is the engine behind internet data transfers, and the fundament of Web services. XML is in fact â€Å"the brother† of HTML (HyperText Markup Language), as the two have a series of resemblances. But there are some distinctions that cannot be overseen. First of all, they have a common origin SGML (Standard Generalized Markup Language), a general language that, through mechanisms similar to those of classic grammar, offers users the possibility of electronically structuring their data [Airinei,1995]. So, practically, HTML uses a set of tags which fine the way that the information will be displayed in the browser. The set of HTML tags is limited and not Customizable, and is generated through SGML technologies. Under these conditions, there is no way for you to customize you set of tags, and this lack of flexibility is an important restraint in some cases. So, with applications that use databases, using HTML is improper for transmitting data. Unlike HTML, XML offers users the possibility of building their own set of tags which can be used for formatting the document. This offers a high level of flexibility, as this element is necessary in defining specialized electronic documents. Normally, you may wonder: if a general language existed SGML, why was there a need for XML? The answer is simple – by its nature, SGML is a highly complex language, and is very hard to use on a large scale, so a simplifies system was created in the form of XML (Alter 2000,2002). Figure 1 – Interoperability for Application Web services are built on fundamental Internet technologies. So, for transmitting Internet technologies, these solutions use standard HTTP protocol (HyperText Transfer Protocol) and the transferred data is cased in XML files. Considering that both technologies are basic Internet elements, they will ensure the accessibility of the applications on any available platform. Unlike Web services, its predecessors had the main disadvantage of not offering such a wide portability range. Therefore, DCOM and CORBA were not accepted by all ITC solution providers, and this would determine limits in their usage. Considering the heterogeneity of the Internet, a technology needs to be supported by the widest possible range of users for it to be considered a universal Internet technology [5]. Plus, DCOM and CORBA technologies use binary files for transferring data and communicating between applications, and this contributes to a lower portability. Unlike these, Web services use XML for data transfer, which consist in simple text files, ensuring a maximum range of portability. Web services use port 80 which is the standard assignation for the HTTP protocol. In comparison, the 2 alternative technologies use their own protocols for transmitting data, and this determines the necessity for additional ports on the application server. In a world that is dominated by the n eed for a higher security level, this disadvantage of the CORBA and DCOM technologies could have a negative impact over the entire In conclusion, one could consider that the widespread of Web technologies in the past years comes from their compatibility with the two generally accepted technologies HTTP and XML. Considering there advantages, the specialists from IDC (a company for surveying and analyzing the ITC environment) consider that Web services will become the fundamental way of application distribution, surpassing all other alternative ways of application distribution (Damsgaard, 2000). Web services are a great part of the most important application development instruments. Microsoft, Oracle or IBM –not necessarily in this order – are the main promoters of this way of application distribution, integrating advanced development instruments for serving these purposes (Forrester Research,2009). This paper has chosen Microsoft’s development environment Visual Studio.Net. I have made this choice considering its advantages as well as its wide spread among developers in our country and abroad. The .Net version of Visual Studio, that was launched in the beginning of the year, offers an efficient way of development and of integrating Web services into one’s own applications. Considering that XML stands at the basis of these technologies, most available instruments are now using this language. We must add that the ADO.NET (ActiveX Data Object) object collection, used in developing database applications, is based exclusively on this language (Iyer,2003). Also, the new version proposes a common software framework (.Net Framework) that offers the possibility of accessing the libraries similarly by any application that has been written in a language that is compatible with this platform. Therefore, the environment shows a common application development framework, and the common element is CLR (Common Language Runtime). CLR translates any application that has been written in a language that is compatible with the technology into an intermediate language – Microsoft I ntermediate Language (IL). The applications that are available in this intermediate method can be transferred and executed onto the desired platform. This platform currently offers 21 application development languages, starting with the classic Cobol and ending with the modern C#. Our example used Visual Basic.Net. (Là ¶wer,1995) Web services will be provided using ASP.Net technology (Active Server Page). ASP is one of the main Web technologies, offering the development of dynamic web pages with database support. The latest version (ASP.Net), offers as a main novelty the possibility of creating and distributing web services. Plus, another set of facilities is included, and here are the most important ones: The possibility of separating the main code of the application from the static representation code of the pages that has been written in HTML; ASP.Net applications can be created in one of the 21 available languages; ASP.Net offers a complete set of server run controls, and this contributes to a better application interface. Figure 2 .NET Framework Architecture 4. Research The research was realised for 38 companies that are between the first 200 from Romania considering the 2010 turnover and its main purpose was to identify how the interoperability technologies were implemented. The enterprises come from different fields, such as financial-banking, telecommunications, retail and industry. The study was developed during December 2011-February 2012 and included a set of questions, from which we mention the most important. Did you implement / Do you plan to implement a technological solution dedicated to integrated informatics system interoperability within the enterprise? 65% of the companies implement solutions for the interoperability of informatics systems, and the rest of 35% plan to implement these solutions within one year. Did the interoperability technologies contribute to the improvements of processes within the enterprise? Those companies that use the interoperability systems have come to the conclusion that interoperability technologies lead a major role for the improvements of processes. 95% of the companies have registered increased efficiency. More than 60% of the companies have registered an increased performance within the company, as well as a faster adherence to certain imposed standards. Do you use integrated informatic systems with business partners? Although most of the companies apply informatic systems destined to the interoperability of internal informatic systems, the integration with the business partners is extremely reduced. Only 6% of the companies use components that allow the interoperability of their systems with their business partners’. The main reason for this low integration is determined by the lack of national or industry standards. Are the systems within the company integrated with those of public institutes? Only 1% of the participants have informatic systems in integration with those of the public institutions (such as city halls, fiscal administration, etc.). The main reason for this situation is the lack of national standards for the systems integration with different public authorities. The lack of these standards and also the frequent changes are also the reason for the low level of implementation. Which are the integrated systems categories? The most frequent system integrations are related to web-based systems and different e-business categories (business-to-business or business-to-customer) with ERP systems (Enterprise Resource Planning) implemented by enterprises. In the financial-banking department, the integration is between the Internet Banking and core-banking systems. 5. Conclusions and implications We are living in a world that is dominated by the need for interoperability between different informational systems running on different platforms. Under these circumstances, Web services are the technology able of efficiently solving this problem. The simplicity of Web services (simplicity that results from the compatibility with basic Internet technologies) ensures the universal acceptance of this solution as a way of communicating between applications. Plus, the relatively simple way of developing these elements will undoubtedly lead to their becoming widespread. Visual Studio.Net, by its integrated development instruments, became one of the main solutions serving this purpose. References Aamodt, A., and Plaza, E. (1996).

Mkt 310 Exam 2 Study Guide

MKT 310 : Exam 2 Study Guide BOOK Ch. 5 : International Trade Theory An Overview of Trade Theory: * The Benefits of Trade – Some international trade is beneficial, exchange products you can produce at a low cost for some products you cannot produce at all * Free Trade – The absence of government barriers to the free flow of goods and services between countries. * International trade allows a country to specialize in the manufacture and export of products it can produce most efficiently while importing products that can be produced more efficiently in other countries. Climate and natural resources explain why Ghana exports cocoa, and Saudi Arabia exports oil * Product Life-Cycle Theory – Early in their life cycles, most new products are produced in and exported from the country in which they were developed. As the product becomes accepted internationally, production begins to start in other countries. Thus suggesting that the product may ultimately be exported bac k to the country of its original innovation. New Trade Theory – Theory that sometimes countries specialize in the production and export of particular products not because of underlying differences in factor endowments, but because in certain industries the world market can support only a limited number of firms. Mercantilism: * Mercantilism – Originated in England, An economic philosophy advocating that countries should simultaneously encourage exports and discourage imports. It was in the countries best interest to maintain a trade surplus, to export more than it imported. Also advocated government intervention to achieve a surplus in the balance of trade. Zero-Sum Game – A situation in which an economic gain by one country results in an economic loss by another. The flaw with Mercantilism is that it is viewed as a Zero-Sum Game. * Critics think China is pursuing a neo-mercantilist society, deliberately keeping its currency value low against the U. S. dollar in order to sell more goods to the U. S. , thus creating a surplus and foreign exchange reserves. Absolute Advantage: * Absolute Advantage – A country has an absolute advantage in the production of a product when it is more efficient than any other country in producing it. According to Smith countries should specialize in the production of goods for which they have an absolute advantage and then trade these for goods produced by other countries. (Countries should never produce goods at home that it can buy at a lower cost from other countries. Comparative Advantage: * Comparative Advantage – It makes sense for a country to specialize in the production of those goods that it produces most efficiently and to buy the goods that it produces less efficiently from other countries, even if this means buying goods from other countries that it could produce more efficiently itself. Basic Message of Comparative Trade – Potential world production is greater with unrestricted free trade than it is with restricted free trade. * Immobile Resources – Resources do not always shift easily from on activity to another, some friction is involved. Belief that a country will produce less of some goods but more of others, however not everyone has the skills and knowledge to produce the greater good, thus some people may lose their jobs. * Diminishing Returns – When more units of a resource are required to produce each additional unit.First not all resources are of the same quality, and different goods use resources in different proportions. * Constant Returns to Specialization – The units of resources required to produce a good are assumed to remain constant no matter where one is on a country’s production possibility frontier. * Dynamic Effects and Economic Growth – Opening an economy to trade, might increase a countries stock of resources as increased suppliers of labor and capital from abroad become available for use within th e country, and free trade might increase the efficiency with which a country uses its resources. When a rich country(U. S. ) enters in free trade with a poor country(China) the lower prices that U. S. consumers pay for goods imported from China may not be enough to produce a net gain for the U. S. economy if the dynamic effect of free trade is to lower real wage rates in the U. S. * Evidence for the Link between Trade and Growth – Countries that adopt a more open stance toward international trade enjoy higher growth rates than those that close their economies to trade. Heckscher-Ohlin Theory: Comparative advantage arises from differences in national factor endowment, and by factor endowment they meant the extent to which a country is endowed with such resources as land, labor, and capital.. The Heckscher-Ohlin Theory predicts that countries will export those goods that make intensive use of factors that are locally abundant, while importing goods that make intensive use of fa ctors that are locally scarce. * The Leontief Paradox – Since U. S. was relatively abundant in capital compared to other nations, the U. S. would export capital intensive goods and import labor-intensive ones. However he found that the U.S. exports were less capital intensive than the imports. The Product Life-Cycle Theory: * Most new products were initially produced in the U. S. and sold in the U. S. markets first, the wealth and size of the U. S. can them strong incentives to develop new consumer products. , in addition the high cost of U. S. labor gave U. S. firms an incentive to develop cost-savings process innovations. These expensive goods are only appealing to the wealthy of other nations, thus there isn’t that much overall global interest, so no other countries feel it is necessary to start producing the product as well. New Trade Theory: The ability of firms to attain economies of scale might have important implications for international trade. * Economies of Scale – Unit cost reductions associated with a large scale of output * New Trade Theory makes 2 important points: * 1) Through its impact on economies of scale, trade can increase the variety of goods available to consumers and decrease the average costs of those goods. * 2) In those industries where the output required to attain economies of scale represents a significant proportion of total world demand, the global market may be able to support only a small number of enterprises. First-Mover’s Advantage are the economic and strategic advantages that accrue to early entrants into an industry. The ability to capture scale economies ahead of later entrants, and thus benefit from a lower cost structure, is an important first mover’s advantage. * Implications of New Trade Theory – generates for government intervention and strategic trade policy, a nation may befit from trade even if they do not differ in resource endowments or technology, trade allows a nati on to specialize in the production of certain products—attaining scales of economy and lowering cost.National Competitive Advantage: Porter’s Diamond * Porter theorizes that 4 broad attributes of a nation shape the environment in which local firms compete, and these attributes promote or impede the creation of competitve advantage. These attributes are†¦Ã¢â‚¬ ¦ * Factor Endowments – A nations’ position in factors of production such as skilled labor or the infrastructure necessary to compete in a given industry (Advanced factors are the most significant competitive advantage. ) * Demand Conditions – the nature of home demand for the indutry’s product or service. Relating and Supporting Industries – the presence or absence of supplier industries and related industries that are internationally competitive. * Firm strategy, Structure, and Rivalry – The conditions governing how companies are created, organized, and managed and the nature of domestic rivalry. * He argues that firms are most likely to succeed in nindustries or industry segments where the diamond is most favorable.. The diamond is a mutually reinforcing system – meaning the effect of one attribute is contingent on the state of others. ———————————————— Ch. 6 : The Political Economy of International Trade Instruments of Trade Policy: * Tariffs – A tariff is a tax levied on imports (or exports. ) In most cases tariffs are placed on imports to protect domestic producers from foreign competition by raising the price of imported goods. Tariffs also produce revenue for the government. The government and the domestic producers gain from having tariffs, whereas the consumers lose. * 2 conclusions can be made about tariffs: First, tariffs are pro-producer and anti-consumer.Second, import tariffs reduce the overall efficiency of the world economy. (Tariffs encourage domestic products to be sold at home when they could be more efficiently sold in the global market. ) * Export tariffs raise money for the government, and they reduce exports from a sector, often for political reasons. * 2 Types of Tariffs: * Specific Tariffs – Levied as a fixed charge for each unit of a good imported (ex. $3 per barrel of oil) * Ad Valorem Tariffs – Levied as a proportion of the value of imported goods. Subsidies – A subsidy is a government payment to a domestic producer. By lowering production costs, subsidies help domestic producers in 2 ways: 1) competing against foreign imports and 2) gaining export markets. * Agriculture is the largest beneficiary of subsidies. * Non-Agriculture subsidy ex. Money given to Boeing and Airbus * The main gains from subsidies accrue to domestic producers, whose international competiveness is increased as a result. * Subsidies protect the inefficient and promote excess prod uction. Import Quotas and Voluntary Export Restraints – An import quota is a direct restriction on the quantity of some good that may be imported into a country * Tariff Rate Quota – The process of applying a lower tariff rate to imports within the quota than those over the quota. * Voluntary Export Restraint – A quota on trade imposed by the exporting country, typically at the request of the importing country’s government. Ex. Limitation on auto exports to the U. S. enforced by the Japanese automobile producers. * Quota Rent – The extra profit producers make when supply is artificially limited by an import quota. Local Content Requirements – A requirement that some specific fraction of a good be produced domestically. Ex. Buy America Act specifies that government agencies must give preference to American products when putting contracts for equipment out to bid unless the foreign products have a significant price advantage. * Administrative Policies * Administrative Trade Policies – Bureaucratic rules designed to make it difficult for imports to enter a country, as it has been argues that the Japanese are masters of this trade barrier. * Antidumping Policies Dumping – Selling goods in a foreign market at below their costs of production or below their â€Å"free† market value. Ex. 2 South Korean manufacturers of semiconductors were accused of selling microchips in the U. S. market at below their cost of production. * Anti-Dumping Policies – Policies designed to punish foreign firms that engage in dumping and thus protect domestic producers from unfair foreign competition. * Countervailing Duties – Antidumping duties. Political Arguments for Intervention: * Protecting Jobs and Industries – Tariffs placed on steel in 2002 by G.W. Bush were supposed to do this. * National Security – Protect the area of technological advancement, and the defense industries. * Retaliation â₠¬â€œ Use threat to intervene in trade policy as a bargaining tool to help open foreign markets and force trading partners to â€Å"play by the rules. † Ex. U. S. has used threat of punitive trade sanctions to try and get the Chinese government to enforce its intellectual property laws – China cost Microsoft hundreds of millions of dollars per year in lost sales revenues. * Protecting Consumers – Ex.Many countries decided to ban imports of American beef after one case of Mad Cow Disease was found. * Furthering Foreign Policies Objectives – Governments sometimes use trade policy to further support their foreign policy objectives. * Helms-Burton Act – This act allows American to sue foreign firms that use property in Cuba confiscated from them after the 1959 revolution. * DAmato Act – Act passed in 1996, similar to the Helms-Burton Act, but this one is aimed at Libya and Iran. * Protecting Human Rights – Ex.Debate over many years on whet her to grant the â€Å"Most Favorable Nation† to China — this is controversial bc many think China doesn’t regard human rights per the Tiananmen Square Massacre. * Protecting the Environment – Strong relation between income levels and environmental pollution/degradation. Ex. Carbon Emissions Tariff, etc. Economic Arguments for Intervention: * The Infant Industry Argument – New industries in developing countries must be temporarily protected from international competition to help them reach a position where they can compete on world markets with the firms of developed nations. Skepticism because protection of manufacturing from foreign competition does no good unless the protection helps make the industry efficient. Second, the infant industry argument relies on an assumption that firms are unable to make efficient long term investments by borrowing money from the domestic or international capital market. * Strategic Trade Policy – A Governme nt policy aimed at improving the competitive position of a domestic industry or domestic firm in the world market. It is argued that by appropriate actions, a government can help raise national income if it can somehow ensure that the firm(s) that gain first-movers advantage within an industry are domestic rather than foreign enterprises. * The second component of the strategic trade policy is that it might pay a government to intervene in an industry by helping domestic firms overcome the barriers to entry created by foreign firms that have already reaped the benefits of first-movers advantage.

Didelphodon - Facts and Figures

Name: Didelphodon (Greek for opossum tooth); pronounced die-DELL-foe-don Habitat: Swamps, lakes and rivers of North America Historical Period: Late Cretaceous (70-65 million years ago) Size and Weight: About one foot long and a few pounds Diet: Insects and small animals; possibly omnivorous Distinguishing Characteristics: Opossum-like teeth; semi-aquatic lifestyle; short, powerful jaws About Didelphodon Throughout the history of life on earth, marsupials have been mostly confined to two continents: Australia (where the vast majority of pouched mammals live today) and Cenozoic South America. However, one family of marsupials--the pint-sized opossums--have prospered in North America for tens of millions of years, and are represented today by dozens of species. Didelphodon (Greek for opossum tooth), which lived in late Cretaceous North America alongside the last of the dinosaurs, is one of the earliest opossum ancestors yet known; as far as we can tell, this Mesozoic mammal wasnt significantly different from its modern descendants, burrowing underground during the day and hunting for insects, snails and possibly the hatchlings of prehistoric turtles at night. One of the odd things about Didelphodon is that it was apparently suited to a semi-aquatic lifestyle: the recently discovered skeleton of a nearly intact specimen, recovered near a Triceratops individual, reveals a sleek, otter-like body equipped with a Tasmanian Devil-like head and strong jaws, which may have been used to feast on mollusks in lakes and rivers, as well as insects, plants, and pretty much anything that moved. However, one shouldnt take Didelphodons guest appearances on animated TV documentaries too literally: in one episode of Walking with Dinosaurs, this tiny mammal is depicted unsuccessfully raiding a clutch of Tyrannosaurus Rex eggs, and an installment of Prehistoric Planet shows Didelphodon scavenging the carcass of a juvenile Torosaurus!
