APPLICATION ARCHITECTURE

Dexter develops workflow applications based on a three-tier model: a web based front end, a database, and a backend. Libraries to store common business rules are accessible from all levels.

In a generic application, the backend collects data from external sources of information (legacy mainframes, external applications, external service providers). This data is stored in a local database. The web front end then presents this data to the end user.

We have found this model to be advantageous for workflow and business process mechanization projects. It is modular, flexible, and scalable. Dexter has used this architecture to support applications with thousands of web users, having hundreds of backend communication channels.
