Architecture Model



The following diagram shows the different architecture models as specified by Gartner Group. An architecture can be classified in one of the five categories, depending on where each logical component (User Interface, Business Logic and Database) executes. By Server we mean database or application server(s) and by Client the PC.


gartner architecture model

CRM.COM Software maps to the “Distributed Interface” model. CRM.COM Software is purely developed on the J2EE (Java 2 Enterprise Edition) platform. The J2EE platform uses a distributed multitiered application model for enterprise applications. Application logic is divided into components according to function, and the various application components that make up a J2EE application are installed on different machines depending on the tier in the multitiered J2EE environment to which the application component belongs. The CRM.COM Software components are described in more detail in the next chapter.


The J2EE application parts shown in Figure 2.1.2 are mapped to J2EE Components.

  • Client-tier components run on the client machine.
  • Web-tier components run on the J2EE server.
  • Business-tier components run on the J2EE server.
  • Enterprise information system (EIS)-tier software runs on the EIS server.

Although a J2EE application can consist of three or four tiers (application, client and web client) as shown in Figure 2.1.2, J2EE multitiered applications are generally considered to be three-tiered applications because they are distributed over three locations: client machines, the J2EE server machine, and the database at the back end.


CRM.COM Software – Gartner architectural model 1
CRM.COM Software maps closely to the first model depicted on figure 2.1.1. The User Interface is generated on the web server (Web container) and then transferred to the client PC. The application server (EJB container) handles the Business logic. As depicted on figure 2.1.2 the Web and Business tiers comprise the Middle tier and the EIS (Enterprise Information System tier) contains the RDBMS. The various layers (components) and their functionalities are summarized on the table below.
