Basis database or OpenText Collections Server is an Extended Relational Database Management System (RDBMS) produced by OpenText. BASIS was originally developed by the Battelle Institute , and was spun off into Information Dimensions, a private company based out of Columbus Ohio.
A relational database (RDB [1]) is a database based on the relational model of data, as proposed by E. F. Codd in 1970. [2]A database management system used to maintain relational databases is a relational database management system (RDBMS).
Formally, a "database" refers to a set of related data accessed through the use of a "database management system" (DBMS), which is an integrated set of computer software that allows users to interact with one or more databases and provides access to all of the data contained in the database (although restrictions may exist that limit access to particular data).
If, however, data is lost in a distributed system, retrieving it would be very easy, because there is always a copy of the data in a different location of the database. Designing a centralized database is generally much less complex than designing a distributed database, as distributed database systems are based on a hierarchical structure.
A distributed database is a database in which data is stored across different physical locations. [1] It may be stored in multiple computers located in the same physical location (e.g. a data centre); or maybe dispersed over a network of interconnected computers.
In numerical analysis and approximation theory, basis functions are also called blending functions, because of their use in interpolation: In this application, a mixture of the basis functions provides an interpolating function (with the "blend" depending on the evaluation of the basis functions at the data points).
