Powerful Object Modeling

The ObjectStudio modeling tool integrates the design of complex business objects generation, presenting a high-level, business-like interface that delivers user-friendly tools for working with objects. The object modeling tool supports case analysis, event diagramming, CRC cards and notations, including industrystandard UML.

Automated Code Generation

Using ObjectStudio, an application moves from the design stage to completion much faster than with traditional tools. The ObjectStudio modeling tool can modify and maintain applications more quickly and easily because class hierarchies and object relationships can be arranged graphically, without coding. Simply make changes to the model and then let the modeling tool generate the code automatically.

Round-Trip Engineering

Even after an application is rolled out, your job is not done. Everchanging requirements mean ever-changing code. With ObjectStudio, any changes to the business object model are automatically reflected in the code and vice versa. This means that you always have access to a current business model of the application. Using a current visual and easy-to-understand model, your business analysts, training and support team and IT staff can better understand your complex enterprise applications and be productive in less time.

Robust Object Mapping

The ObjectStudio mapping tool provides visual, drag-and-drop tools for linking objects to databases. The Object Relational Mapper uses the resulting object mapping definitions to make application connections to your database, without requiring any SQL code to be written into the application. This allows the developer to concentrate on objects without worrying about the details of the database implementation. This is done automatically.
