Net.Data supplies language environments that you use to access data sources and to execute application programs containing business logic. For example, the SQL language environment lets you pass SQL statements to a DB2 database, and the REXX language environment lets you invoke REXX programs. You can also use the SYSTEM language environment to execute a program or issue a command.
With Net.Data, you can add user-written language environments in a pluggable fashion. Each user-written language environment must support a standard set of interfaces that are defined by Net.Data and must be implemented as a service program. For complete details on how to create a user-written language environment, see the Net.Data Language Environment Interface Reference.
Figure 8 shows the relationship between the Web server, Net.Data, and the Net.Data language environments.
