Many applications are implemented with a three-tier architecture wherein data is stored in the database. The web server runs Java services that access the database and retrieve the information. The Java classes are responsible for the business logic that receives a call from the client tier, assembles the information from the database, and returns the result.
The client tier utilizes browser technology that runs a Flash application to provide an interface to the user and calls the Java services for required information. The client workstations call the Tomcat server, which calls the database to gather data and executes the Spring services that contain the application’s business logic.
