| Product :::Architecture Simple, scalable, robust, open EA WebModeler is a server based application. It resides behind a standard web server (e.g. Websphere, Ms IIS, Apache) and stores information in a standard relational database management system (e.g. Oracle, SQL Server, DB2, Access etc. ). EA WebModeler receives requests from clients using standard web browsers (e.g. Netscape, Internet Explorer) and satisfies these by using information in the repository stored in the relational database, linked knowledge assets stored on the host file system, or hyperlinks to external assets on the intranet or Internet.
EA WebModeler supports many users concurrently via the single server copy. Clients are standard browsers without the need for any plug ins or helper applications. The browser need support only HTML and Java Script. EA WebModeler manages all repository changes using transactions. This is done to ensure that work is not lost, that partial updates cannot occur where difficulty is experienced in the middle of an update and that users do not adversely affect each other. EA WebModeler makes use of the IBM Web Connect and Object Extender features for web session management and object to relational persistence respectively. These, and other robust underlying infrastructure technology, ensures EA WebModeler is stable and scalable. Internally, EA WebModeler uses n-tier design architecture, comprising an interface management layer, business transaction layer and domain object layer. EA WebModeler stores all type definitions in the repository and generates appropriate client interface and business transaction processing logic at run time using process and interface patterns and the relevant meta data.ÿ |
