Figure: - 8.5 SOA basic architecture Above figure describes a broader picture of what service oriented architecture will look like. The basic fundamental of SOA is a web service. In above diagram you can see there are two services available. One is the “Credit Card” service and other is “Address Check” 160
web service. Both these services are provided by different company. Now we want to build a functionality which needs to validate a credit card and also check that addresses are proper. In short we will need functionalities of both the “CreditCard” and “AddressCheck” service. Also note the “CreditCard” service has its own business layer and DAL components, which can be in a proprietary language. It’s very much possible that the whole Credit card service is made in .<strong>NET</strong> and the Address check is SAP implementation or JAVA implementation. But because both the systems provide there functionality using Web services which is nothing but basically XML message communication. So we have made new service which sits like a FAÇADE on top of both the web service and performs both functionalities in one common service. You will see I have made a third service which sits on top of both the webservice and consumes them. Also you can see that the UI part of the systems have access to Buisness layer and Web service of there system. But the service which does both these check has only access to the Web service. Note:- It’s beyond the scope of this book to discuss about SOA. But just to keep you safe during interview this book has tried to clear some basics of SOA. (I)What are different ways you can pass data between tiers? There are many ways you can pass data between tiers :- √ √ √ √ Dataset the most preferred one as they maintain data in XML format. Datareader Custom classes. XML (A)What is Windows DNA architecture? Note :- If you have worked with classic ASP this question can come to you. The Windows Distributed interNet Applications Architecture (DNA) is a Microsoft blueprint for robust, scalable, distributed business software. Windows DNA has evolved over time and was not preplanned. It gives all combined advantages of Centralized mainframe, application servers, internet technologies and Personal computers. Windows DNA is a evolution which started from mainframes (Where all logic was centralized) , Fox pro ages ( Where we talked in terms of two tier systems) , VB6 / SQL SERVER (Three tier where we talked in terms of having one more tier which was mainly COM 161
