Easier to learn than other Object-Oriented Database Systems (ODBMS) - no need to learn a proprietary API - any user with some experience with Hibernate, TopLink, EclipseLink, OpenJPA, JPOX or DataNucleus could start using ObjectDB immediately. SQL-like (but object based) query language - ...
This paper designed and implemented TMOM (Telematics Moving Object Main Memory DBMS) to meet efficiently the requirements that telematics services should be provided in real-time. TMOM follows the spatial data model of OpenGIS "Simple Features Specification for SQL", and provides spatial, spatio-...
In their influential paper, The Object-Oriented Database Manifesto, Malcolm Atkinson and others define an OODBMS as follows: An object-oriented database system must satisfy two criteria: it should be a DBMS, and it should be an object-oriented system, i.e., to the extent possible, it shoul...
Regardless whether the underlying database model follows the object-oriented, the rela tional or the object-relational paradigm, a key feature of any DBMS product is content based access to data sets. On the one hand this feature provides user-friendly query interfaces based on predicates to ...
Formally, an object-oriented database model is a tuple (CS,AS,RS,O,M,S), in which CS is a finite set of classes, AS is a finite set of attributes, RS is a finite set of relationships, O is a finite set of objects, M is a finite set of methods, and S is a finite set of...
Complex Data Model Example For example, your firm might use purchase orders to organize its purchasing, accounts payable, shipping, and accounts receivable functions. A purchase order contains an associated supplier or customer and an indefinite number of line items. In addition, applications often ne...

In the late 1980s and early 1990s, a new form ofDBMSwas introduced to the data management marketplace, the object-orienteddatabase management system(OODBMS). Unlike the RDBMS products, OODBMS products suffered from not having a formal data model on which their design was based. As a result,...
