Achievements and Weaknesses of Object-Oriented Databases

Sikha Bagui
2003 Journal of Object Technology  
Object-oriented database systems began developing in the mid-80's out of a necessity to meet the requirements of applications beyond the data processing applications which were [are] served by relational  ...  Complex objects, methods and encapsulation add to the complexity of query processing in the OODBs. Complex objects create path expressions that complicate query processing.  ...  When queries are formulated in the direction not supported by references, the query will be processed by sequential scan [15] .  ...

An architecture for integrating OODBs with WWW

Jack Jingshuang Yang, Gail E. Kaiser
1996 Computer networks and ISDN systems  
Our chosen architecture provides high flexibility for a wide variety of applications, ranging from managed healthcare to software development environments, and has been realized in the dkweb system.  ...  The OODB (i.e., Darkover) is not altered in any way to support dkweb, which means this approach could apply to an arbitrary OODB.  ...  Conclusions We described an architecture for integrating OODBs with WWW to support dynamically customizable views on the web.  ...

A new architecture for integration of CORBA and OODB

Ruey-Kai Sheu, Kai-Chih Liang, Shyan-Ming Yuan, Win-Tsung Lo
1999 IEEE Transactions on Knowledge and Data Engineering  
The whole task for integrating CORBA and OODB is done transparently by our proposed preprocessor, which plays an important role in solving problems encountered by ORB and OODB vendors easily.  ...  In order to facilitate the use of OODB, the Object Database Management Group (ODMG) defined a standard for object database management system.  ...  The relationship between the CORBA object reference and OODB object handle can be kept in an association table in the RO server process.  ...

Efficient Use of Signatures in Object-Oriented Database Systems [chapter]

Kjetil Nørväg
1999 Lecture Notes in Computer Science  
In an object-oriented database system (OODB) using logical OIDs, an object identifier index (OIDX) is needed to map from logical OID to the physical location of the object.  ...  In this report we show how the signatures can be stored in the OIDX, and used to reduce the average object access cost in a system.  ...  Less has been done in using signatures in ordinary query processing, but signatures have been used in queries on set-valued objects [9] [10] [11] .  ...

Efficient flash retrieval using structural join index hierarchy in an object XML framework

Hon Chung Mak Edmund, Chi-Wai Fung, Qing Li, Chung-Sheng Li, Minerva M. Yeung
2005 Electronic Imaging and Multimedia Technology IV  
In order to allow Flash movies to be queried, we create an OXF (Object XML for Flash) model by converting Flash movies into XML format.  ...  A detailed cost model for query execution through SJIH is developed.  ...  In a query processing environment with multiple queries, one single indexing method is often not enough to expedite all queries.  ...

Of Objects and Databases: A Decade of Turmoil

Michael J. Carey, David J. DeWitt
1996 Very Large Data Bases Conference  
In addition, work was underway elsewhere in the computer science research community on extending programming languages with database-inspired features such as persistence and transactions.  ...  A decade ago, the connection between objects and databases was new and was being explored in a number of different ways within our community.  ...  Research is still needed on object query processing; we believe that this work will need to draw more fully on the large body of work on SQL query processing from the world of relational databases in order  ...
