An overview of the object-oriented database programming language DBPQL

In this paper, we present a new approach to the integration of object-oriented programming languages, database programming languages and query languages. While object-oriented programming languages and languages that are supported by object database systems appear to be closely related, there are a number of significant differences that affect language design and implementation. Such issues include the degree of encapsulation, persistence, the incooperation types and classes, inheritance, concurrency, NULL values, garbage collection etc. In this paper, we outline the respective challenges that affect language design and provide a brief overview of the integrated object-oriented database programming and querying language DBPQL.
