Service-orientation is, as per industry, the correct way to build maintainable, robust, and secure applications. When developing a service-oriented application, you decouple the service code from the technology and platform used by the client. Even securing the transfer of the message itself from the client to the service is also outside the scope of the service, and so is authenticating the caller. The service may do its own local authorization as per the requirements

The JDBC/ODBC bridge driver
A piece of native C-code that translates a JDBC call to an ODBC call. Use this driver for development, not for industrial-strength application environments. Note that you have to have an ODBC database driver manager + an ODBC database driver installed on the server in addition to the JDBC/ODBC bridge.

Association is a relationship where all object have their own lifecycle and there is no owner. Let’s take an example of Teacher and Student. Multiple students can associate with single teacher and single student can associate with multiple teachers but there is no ownership between the objects and both have their own lifecycle. Both can create and delete independently.

Lets say our application uses a component A and now we want to replace A with a component from 3rd party , say it as B.
Since the component B is not in our control which means we dont have control on its interface as well. But the problem here is that our client code is already using interface A and we dont want it to change. How can existing and unrelated classes work in an application that expects classes with a different and incompatible interface? This is the problem we will be going to res
