2. Object database - Wikipedia

   en.wikipedia.org/wiki/Object_database

   Object databases based on persistent programming acquired a niche in application areas such as engineering and spatial databases, telecommunications, and scientific areas such as high energy physics [13] and molecular biology. [14] Another group of object databases focuses on embedded use in devices, packaged software, and real-time systems.

3. Object–relational database - Wikipedia

   en.wikipedia.org/wiki/Object–relational_database

   An object–relational database can be said to provide a middle ground between relational databases and object-oriented databases. In object–relational databases, the approach is essentially that of relational databases: the data resides in the database and is manipulated collectively with queries in a query language; at the other extreme are ...

   Embedded database supporting efficient, distributed management of C++ and Java objects. Avoids the complexities and limitations of ORM products such as Hibernate by storing objects directly with their relationships intact. Uses a page-based mapping system for fast locking and efficient, distributed, client-side caching. ODABA: 12.3.0 (August 2013)

6. Object–relational mapping - Wikipedia

   en.wikipedia.org/wiki/Object–relational_mapping

   Object–relational mapping (ORM, O/RM, and O/R mapping tool) in computer science is a programming technique for converting data between a relational database and the memory (usually the heap) of an object-oriented programming language. This creates, in effect, a virtual object database that can be used from within the programming language.

7. Object-based spatial database - Wikipedia

   en.wikipedia.org/wiki/Object-based_spatial_database

   An object-based spatial database is a spatial database that stores the location as objects. The object-based spatial model treats the world as surface littered with recognizable objects (e.g. cities, rivers), which exist independent of their locations. Objects can be simple as polygons and lines, or be more complex to represent cities.

8. Real-time database - Wikipedia

   en.wikipedia.org/wiki/Real-time_database

   A conventional database cannot work under these circumstances because the inconsistencies between the real world objects and the data that represents them are too severe for simple modifications. An effective system needs to be able to handle time-sensitive queries, return only temporally valid data, and support priority scheduling.
