Model-driven development of large-scale web applications

This paper describes our approach to support the development of large-scale Web applications. Large development efforts have to be divided into a number of smaller tasks of different kinds that can be performed by multiple developers. Once this process has taken place, it is important to manage the consistency among the artifacts in an efficient and systematic manner. Our model-driven approach makes this possible. In this paper, we discuss how a metamodel is used to describe part of the specification as a central contract among the developers. We also describe a tool that we implemented on the basis of the metamodel. The tool provides a variety of code generators and a mechanism for checking whether view artifacts, such as JavaServer PagesTM, are compliant with the model. This feature helps developers manage the consistency between a view artifact and the related business logic--HyperText Transfer Protocol request handlers.

Design of an Integrated and Extensible C++ Programming Environment

This paper describes a framework and some techniques used in the construction of integrated and extensible programming environments. To support programming in complex object-oriented languages such as C++, a database that contains semantic information on the source programs is essential. Tools in such environments should be constructed in a highly integrated fashion around the database. In addition, new programming techniques and the acquisition of knowledge through experience create a need for extensions. Such environments have to be designed so that extensions can be made easily. Thus integration and extensibility are key features of such environments.
