Queries and query processing in object-oriented database systems

David D. Straube, M. Tamer Özsu
1990 ACM Transactions on Information Systems  
Object-oriented database management systems (OODBMS) combine the data abstraction and computational models of object-oriented programming languages with the query and performance capabilities of database  ...  Query processing issues such as query safety and object calculus to object algebra translation are discussed in detail.  ...  We would especially like to acknowledge Jim Hoover's assistance in simplifying the translation algorithm in Section 4.  ...

Using path information for query processing in object-oriented database systems

Dik L. Lee, Wang-chien Lee
1994 Proceedings of the third international conference on Information and knowledge management - CIKM '94  
This paper argues that most queries in object-oriented databases require traversing from one object to another in the aggregation hierarchy.  ...  Thus, the connections between objects through object identifiers are essential to the efficiency of query processing and should be represented separately from the database.  ...  Lee, "Path dictionary: A new approach to query processing in object-oriented databases," in preparation.

Query processing issues in object-oriented database system-preliminary ideas

M.T. Ozsu
[Proceedings] 1991 Symposium on Applied Computing  
In this paper we discuss the issues that need to be considered in the development of query models and in the implementation of query processors in object-oriented database systems. 3 12 TH0355-8/91/0000  ...  However, the task is complicated in object-oriented systems due to the richness of the data model.  ...  These complications affect query processing very directly since the optimization of queries in an object-oriented system can and should take advantage of the semantics of sharing.  ...

On processing nested queries in distributed object-oriented database systems

Wang-Chien Lee, Dik Lun Lee
Proceedings RIDE-DOM'95. Fifth International Workshop on Research Issues in Data Engineering-Distributed Object Management  
In this paper, we discuss nested query processing in a distributed object-oriented database system. We present three query processing strategies to exploit parallelism in a distributed environment.  ...  Then, we review three a ccess methods designed for centralized systems and discuss how they can be applied to the distributed e n v ironment.  ...  Query Processing for OODBSs In object-oriented database systems, an entity is represented as an object, which consists of methods and attributes.  ...

Object Oriented Query Response Time for UML Models

Vipin Saxena, Santosh Kumar
2012 Journal of Software Engineering and Applications  
Due to increase of size of database complexity of database is increasing therefore, it is necessary to optimize the object oriented query response time from the complex object oriented database.  ...  A UML model is designed for computing the object oriented query response time. Table and graph are also represented for the computed records in five runs.  ...  The queries related to object oriented databases support the object oriented features. Any query which returns the result in particular time is called as response time of the query.  ...

Object Query Optimization through Detecting Independent Sub queries

Mohammad Farhan, Yatin Chauhan, Mohammad Akhtar, Fayeem Khan, Poonam Pangarkar
2014 IOSR Journal of Computer Engineering  
Database Switching includes execution of queries on same or different machines connected in LAN with different backend without rewriting any queries.  ...  Switching between the databases reduces the work of rewriting the queries for each of the database thus saving time.  ...  Object-oriented languages allow expressing queries explicitly in the code, which are optimized using the query optimization techniques from the database domain.  ...
