Object-relational database - An object-relational database (ORD) or object-relational database management system (ORDBMS) is a relational database management system that allows developers to integrate the database with their own custom data types and methods. The term object-relational database is sometimes used to describe external software products running over traditional DBMSs to provide similar features; these systems are more correctly referred to as object-relational mapping systems.

Secondary database server - A secondary database server or SDS is a database server that is kept in synchronisation with the main database so that if the main database goes offline, the secondary database server can be used instead. This is important for a live system that must be online 24 hours a day, and most DBMS systems that support SDSs are capable of automatically detecting and switching to the secondary server within seconds of the main server going offline.

Universal database - A universal database would be a database which would be capable of storing any type of data of any type of universe (real or virtual) as well as all the data relationships without ever having to change or modify the basic structure of the database itself. Data alone would determine the relationships (such as that which the relational database model determines through the use of a schema).

Database instance - A database instance consists of the running operating environment which allows users to access and use a database. A database (as a generic structured store of data) becomes an instance when instantiated as a system and made available via its database management system.
