Identify the types of businesses to be executed on the system.

You can execute the following two types of businesses on Application Server systems:

• Online business
  This type of business processes requests sent from clients via a network.
  
• Batch business
  This type of business processes routine or periodic work in batch.
  

The format of an application to be executed or a server process that executes the application differs depending on the types of business. The following table describes the correspondence of the business types, application formats, and server processes that execute applications:

Table 2-1 Correspondence of the business types, application formats, and server processes that execute applications

Business type	Format of application	Server process that executes the application
Online business	J2EE application	J2EE server
Batch business	Batch application	Batch server

Hint

The contents of the system design to be implemented subsequently differ depending on the business type. Implement the required system design according to the business type. The following table describes the contents of the system design to be executed as per the business type and the corresponding reference sections in this manual:
