The new, Web-enabled, Java-based, SOLoist 4 is announced here...
Purpose

SOLoist
is a framework for model-driven development, fast prototyping, and rapid implementation of database applications using executable UML.

Contents
SOLoist package is comprised of:
- The technology for building contemporary OO information systems (OOIS) using executable UML
- Framework (including runtime environment, code generators, and utilities) for rapid OOIS development
- Set of reusable and customizable generic modules for common business needs
Key Benefits
The SOLoist approach brings a lot of benefits to the users and investors:
- By using and interpreting completely the pure object-oriented conceptual basis, the user is motivated to think in the OO manner. The OO paradigm has a lot of advantages over the traditional relational data model, as is commonly recognized nowadays.
- The usability of the system is improved a lot, due to an intuitive, graphical user interface, which spares the user from dealing with tedious keys, codes, filling in forms, etc. Instead, the user interface follows the contemporary presentational approaches such as tree views, icons, diagrammatic data manipulation, drag-and-drop, etc. Users manipulate with live objects, instead of dead data!
- Due to the much improved development technology, the development time and costs are significantly reduced in comparison with other traditional approaches.
- Due to the usage of the OO paradigm, the systems built using SOLoist are much more flexible than those built using other traditional approaches. This may pay off on a long term of the system's exploitation.
Features
The development of such systems using SOLoist is characterized with:
- Full compliance to the UML semantics
- Execution support for the UML semantics, without need for tedious and complex manual mapping to lower-level implementation mechanisms in the target language code. The concepts of the UML are directly supported by the SOLoist runtime environment, so the UML in SOLoist has become executable!
- Customizing presentation and behavior of application by interactive demonstration
- Querying of object space using Object Query Language (OQL)
- Rapid prototyping, because the majority of system's functionality can be supported by the built-in generic mechanisms
- Easy customization, because everything in SOLoist can be arbitrarily extended using traditional programming techniques
- SOLoist relies upon stable and reliable relational database technology for persistent storage; SOLoist builds an upper layer that provides an object view to the storage that is not directly visible to the modeler and user.
Technical Characteristics
Currently supported development platforms:
- Third-party UML modeling tool (plug-ins available on request)
