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-...
SQL-like (but object based) query language - familiar to most developers. Friendly API JPA is very simple, except for mapping, which is irrelevant to ObjectDB. Persistence is set using JPA/JDO annotations (e.g. @Entity, @Id, @Index). Transparent activation (no activation depth) - ...
These are inherited: All the attributes declared in or inherited by the supertype. Any methods declared in or inherited by supertype. Example 2-15defines thestudent_typobject as a subtype ofperson_typ, which inherits all the attributes declared in or inherited byperson_typand any methods inherite...
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 ...

Based on similarity relationship that is originally used in the fuzzy relational databases [44], George et al. [105] use the range of attribute values to model the set of allowed values for an attribute of a given class. Then the inclusion of the actual attribute values of the given ...

* Not-mappable concepts: not all of the concepts defined in the conceptual model can be mapped directly onto the object-relational model (e.g. Model-driven development of content-based image retrieval systems This book examines all of the major database models, including hierarchical, network, ...
