Accessing a Functional Database via CODASYL-DML Transactions.
NAVAL POSTGRADUATE SCHOOL MONTEREY CA
Pagination or Media Count:
Conventional approaches to the design and implementation of database systems have been upon the premise of a single data model with its model-based data language, thus restricting the database system to transactions based solely on a specific model and written in a specific data language. This traditional approach has drastically hindered the widespread interaction of database systems based on various data models and languages. As an alternative to this traditional and less effective approach to database systems, the multi-lingual database system MLDS has evolved. MLDS has allowed via their corresponding data language. This thesis implements a methodology for accessing and manipulating databases stored in a particular data model via transactions of a separate data model specifically, a functional database is accessed via CODASYL-DML transactions. This interface is the initial move toward extending MLDS to a thoroughly Multi-Model Database System MMDS.
