    • A database is an organized collection of data, generally stored and accessed electronically from a computer system. Where databases are more complex they are often developed using formal design and modeling techniques.

      The database management system (DBMS) is the software that interacts with end users, applications, and the database itself to capture and analyze the data. The DBMS software additionally encompasses the core facilities provided to administer the database. The sum total of the database, the DBMS and the associated applications can be referred to as a "database system". Often the term "database" is also used to loosely refer to any of the DBMS, the database system or an application associated with the database.

      Computer scientists may classify database-management systems according to the database models that they support. Relational databases became dominant in the 1980s. These model data as rows and columns in a series of tables, and the vast majority use SQL for writing and querying data. In the 2000s, non-relational databases became popular, referred to as NoSQL because they use different query languages.


    • Database: a structured collection of information in computerized format, searchable by various types of queries; in libraries, often refers to electronic catalogs and indexes.


    • QUOTE: Structured Data. Structured data are data that have been represented in a manner that allows computation with those data. For example, the data within MetaCyc are highly structured because different properties and relationships of metabolic enzymes, pathways, and reactions have been carefully dissected and assigned to distinct fields of a database so that they are independently queryable and computable. Therefore, we can ask questions across the data such as "find all enzymes that use magnesium as a cofactor" or "find all pathways in which pyruvate is an input substrate".
