Accessing and Updating Functional Databases Using CODASYL-DML.
Abstract
Traditional approaches to database system design and implementation involve single-model, single-language database systems with their inherent lack of flexibility and extensibility. An alternative to the traditional approach to database system design and implementation is the multi-lingual database system (MLDS). This approach allows the user to access and update one or many databases in different data models using corresponding data languages, thus countering the aforementioned flexibility and extensibility restrictions. This thesis presents a methodology for accessing and updating databases stored in one model with the data manipulation facilities of a different data model. Specifically, anh interface was designed for allowing the network/CODASYL-DMLK user to access and update a functional database as supported by MLDS. This is the first step in the process of extending the multi-lingual database system to a true multi-model database system (MMDS). (Author)
