The name is a three-letter acronym for DataBase Manager, and can also refer to the family of database engines with APIs and features derived from the original dbm. The dbm library stores arbitrary data by use of a single key (a primary key) in fixed-size buckets and uses hashing techniques to enable fast retrieval of the data by key.
The physical schema according to Sowa (2004) "describes the internal formats of the data stored in the database, and the external schema defines the view of the data presented to the application programs". [7] Since the 1970s the NIST had held a series of four workshops on Database and Information Management Directions.
List of relational database management systems, for database management systems based on the relational model. Comparison of object database management systems, showing what fundamental object database features are implemented natively; Document-oriented database, for storing, retrieving and managing document-oriented information
NVD is managed by the U.S. government agency the National Institute of Standards and Technology (NIST). On Friday March 8, 2013, the database was taken offline after it was discovered that the system used to run multiple government sites had been compromised by a software vulnerability of Adobe ColdFusion.

Extended MNIST (EMNIST) is a newer dataset developed and released by NIST to be the (final) successor to MNIST. [15] [16] MNIST included images only of handwritten digits. EMNIST includes all the images from NIST Special Database 19 (SD 19), which is a large database of 814,255 handwritten uppercase and lower case letters and digits.
NIST replaced these codes with the more permanent GNIS Feature ID, maintained by the U.S. Board on Geographic Names. The GNIS database is the official geographic names repository database for the United States, and is designated the only source of geographic names and locative attributes for use by the agencies of the Federal Government.

The Digital Library of Mathematical Functions (DLMF) is an online project at the National Institute of Standards and Technology (NIST) to develop a database of mathematical reference data for special functions and their applications.
A database management system (DBMS) is a computer program (or more typically, a suite of them) designed to manage a database, a large set of structured data, and run operations on the data requested by numerous users.
