Collection database – collection catalog of a museum or archive implemented using a computerized database, in which the institution's objects or material are catalogued. •
Collective Optimization Database – open repository to enable sharing of benchmarks, data sets and optimization cases from the community, provide web services and Plug-in (computing)|plugins to analyze optimization data and predict program transformations or better hardware designs for multi-objective optimizations based on statistical and machine learning techniques provided there is enough information collected in the repository from multiple users. • •
Cooperative database – holds information on customers and their transactions. •
Correlation database – database management system (DBMS) that is data model independent and designed to efficiently handle unplanned, ad hoc queries in an analytical system environment. •
Current database – conventional database that stores data that is valid now. •
Directory – repository or database of information which is optimized for reading, under the assumption that data updates are very rare compared to data reads. Commonly, a directory supports search and browsing in addition to simple lookups. •

EDA database – database specialized for the purpose of electronic design automation. •
Endgame tablebase – computerized database that contains precalculated exhaustive analysis of a chess endgame position. •
Food composition database (FCDB) – provides detailed information on the nutritional composition of foods. •
Full-text database – database that contains the complete text of books, dissertations, journals, magazines, newspapers or other kinds of textual documents. Also called a "complete-text database". •
Government database – collects personal information for various reasons (
mass surveillance, Schengen Information System in the European Union, social security, statistics, etc.). •

Navigational database – database in which objects (or records) in it are found primarily by following references from other objects. •
Non-native speech database – speech database of non-native pronunciations of English. •
Online database – database accessible from a network, including from the Internet. •
Operational database – accessed by an Operational System to carry out regular operations of an organization. •
Parallel database – improves performance through parallelization of various operations, such as loading data, building indexes and evaluating queries. •
Probabilistic database – uncertain database in which the possible worlds have associated probabilities. •
Real-time database – processing system designed to handle workloads whose state is constantly changing (Buchmann). •
Relational database – collection of data items organized as a set of formally described tables from which data can be accessed easily. •
Spatial database – database that is optimized to store and query data that is related to objects in space, including points, lines and polygons. •
Temporal database – database with built-in time aspects, for example a temporal data model and a temporal version of Structured Query Language (SQL). •
Time series database – a time series is an associative array of numbers indexed by a datetime or a datetime range. These time series are often called profiles or curves, depending upon the market. A time series of stock prices might be called a price curve, or a time series of energy consumption might be called a load profile. Despite the disparate naming, the operations performed on them are sufficiently common as to demand special database treatment. •
Triplestore – purpose-built database for the storage and retrieval of triples, a triple being a data entity composed of subject-predicate-object, like "Bob is 35" or "Bob knows Fred". •
Very large database (VLDB) – contains an extremely high number of tuples (database rows), or occupies an extremely large physical filesystem storage space. •
Virtual private database (VPD) – masks data in a larger database so that security allows only the use of apparently private data. •
