Application Development

From MIKE2 Methodology

Traditionally, the Application Development Domain was thought to consist of primarily OLTP application development and MIS application development. This OLTP application development environment consists of a combination of legacy systems and Commercial Off-the-Shelf packages (COTS), each of which typically has their own custom or proprietary databases; the goal of OLTP application development is to develop applications focused on achieving specific business functionality.

Traditionally, this domain would also include MIS application development. Our model moves development of the information repository and integration capabilities of MIS application development into the new domain of Information Development. MIS analytics and reporting development functions stay within the domain of application development.

Proposing changes to the application development model seems appropriate, considering the complexity of changes in this area over the last 10 years:

• Off-the-Shelf Enterprise (OLTP) Applications
• Off-the-Shelf Workflow and Rules Engines
• Composite Applications (Integration-focused) Applications
• Business Intelligence (Information-focused) Applications
• Integrated Applications

As integration becomes more like infrastructure, we believe that composite application development and process-oriented development (workflow) will become more like application development than infrastucture and therefore include this work within the application development domain.
