Extended OQL for Object Oriented Parallel Query Processing

OQL: A Query Language for Manipulating Object-oriented Databases

An essential property which is desirable in a query language designed for a certain data model is that queries issued in that language must produce results that are structured and modeled using the same data msdel. A consequence of maintaining this property in a query language is that the result of a query can be used as an operand in sc+ne other query (or queries) or can bs saved as a user's v...

P-OQL: an OQL-oriented Query Language for Pcte

This paper presents P-OQL (Pcte-Object-QueryLanguage) a domain-oriented query language for Pcte. Pcte is the ECMA standard for a public tool interface (PTI) for system development environments (SDE) and includes as one of its major components a structurally object-oriented object management system (OMS). Whereas the ECMA standard is only concerned with navigational access to the object base, ex...

Object-oriented query language design and processing

ii Abstract This thesis proposes an object-oriented query language that is more powerful than many existing query languages. The language is formally speciied and its expressive power is demonstrated by giving four translation schemes from other prominent object-oriented query languages. Further, this query language can be supported by a query algebra and both the query language and query algeb...
