Web Programming

You can use develop many kinds of COBOL application, including client/server applications, in which most data is kept on a central computer (the server) and accessed from many other computers (the clients). In such applications, queries are entered at a client, and software running locally forwards them to the server where software interrogates or updates the data and returns a response.

Web applications are a particular example of client/server applications. There are two separate facilities for creating Web applications:

• COBOL language extensions that enable you to:
  • Embed HTML commands in your COBOL program
  • Call HTML files
• The Interface Mapping Toolkit and Server Enterprise Edition enable you to deploy an application as a service, which can then be called by a client across the Web.
