As the power of application software has grown, breakthroughs in database technology have been achieved to meet these new demands. Organizations now face the decision of which technology to use, and this choice is not an easy one. What is needed is a model that can be used to structure ...
object database(redirected from object DBMS) object databaseA database that is managed by an object-oriented database management system (ODBMS). Object databases are closely aligned with a particular object-oriented programming language and enable the data in the objects to be persistently stored ...
An object oriented DBMS thus follows an object oriented data model with classes (the schema of objects), properties and methods. An object is always managed as a whole. This means for example, that the insertion of an object, which in a relational system would probably be stored in multiple...
A Methodology for Query Reformulation in CIS Using Semantic Knowledge We consider Cooperative Information Systems (CIS) that are multidatabase systems (MDBMS), with a common object-oriented model, based on the ODMG standard, ... D Florescu,L Raschid,P Valduriez - 《International Journal of Coo...
Moving fields up and down in the class hierarchy is transparent. Support for renaming types, fields and properties. Object Model & Data TypesObjectDB supports persisting complex Java data structures very efficiently. User Defined Classes Entity classes (@Entity) Embeddable types (@Embeddable) ...
An object-oriented database (OODB) is a type of DBMS that is designed to store and manage data using object-oriented principles. Learn more about it through this blog.
Zurich Abstract The analysis of time series is a central issue in econo- mic research and many other scientific applications. Ho- wever, the data management functionality for this field is not provided by general-purpose DBMSs. Therefore, we propose a data model of a specialized Time Series Ma...
These algebras can be inserted in any data model iftheir designs are based on available standards such as Open Geospatial Consortium that provides acommon model for existing DBMS's. In this paper, we focus on extending a spatial data model forconstrained moving objects. Static and moving ...
A man-machine interface in natural language for a DataBase Management System (DBMS) called VORAS, based upon semantics, is presented. This DBMS can also be used for knowledge representation, and is well-suited to the design of queries in natural language. The system VORAS is an object-oriente...
