Database Systems 3rd Edition. Palgrave, Basingstoke, UK. ISBN 1 4039 1601 2 ref A database is an organised pool of logically related data. Data is stored within the data structures of the database. A DBMS is a suite of computer software providing the interface between users and a database or databases. A DBMS is a shell which surrounds a database or series of databases and through which all interactions take place with the database. The interactions catered for by most existing DBMS fall into four main groups Data Definition. Defining new data structures for a database, removing data structures from the database, modifying the structure of existing data. Data Maintenance. Inserting new data into existing data structures, updating data in existing data structures, deleting data from existing data structures. Data Retrieval. Querying existing data by end users and extracting data for use by application programs. Data Control. Creating and monitoring users of the database, restricting access to data in the database and monitoring the performance of databases. Both a database and its DBMS conform to the principles of a particular data model. ref Tsitchizris, D. C. and F. H. Lochovsky 1982 . Data Models.

An online database is a database accessible from a network, including from the Internet . It differs from a local database, held in an individual computer or its attached storage, such as a CD. For the system or software designed to manage a database, see Database management system s DBMS For information on the structure of a database itself, see Database For information on the programs for searching a database, see Search engine s Currently, there are several database products designed specifically as hosted databases delivered as Software as a Service products. These differ from typical traditional databases such as Oracle, Microsoft SQL Server, Sybase, etc. Some of the differences are These online databases are delivered primarily via a web browser They are often purchased by a monthly subscription They embed common collaboration features such as sharing, email notifications, etc. For information on the contents of specific types of database, see Bibliographic database s Customer relationship management To learn about generic online databases that can be used by any software application, see Cloud database .

unreferenced date August 2007 A database engine or storage engine is the underlying software component that a database management system DBMS uses to create, read, update and delete CRUD data from a database . Most database management systems include their own application programming interface API that allows the user to interact with their underlying engine without going through the user interface of the DBMS. Many of the modern DBMS support multiple database engines within the same database. For example, MySQL supports InnoDB as well as MyISAM .

Helix is a pioneering database management system for the Apple Macintosh platform, created in 1983. Helix uses a graphical programming language to add logic to its applications, allowing non programmers to construct sophisticated applications. While this sort of ease of use should have made Helix a killer app on the platform, the uniqueness of the programming language, limitations in the Mac OS it relied on for data I O, the proprietary nature of the databases it created, and a variety of business problems relegated it to a niche product. As of 2005, Helix is twenty one years old, but still has a dedicated, if small, following. Despite being the first multiuser database on any PC platform, the first object based, visual programming tool, and, perhaps, the first relational database on a PC platform, Helix s marketing and ownership problems led it to a life as a niche product on an OS with a small market share.

Refimprove date December 2009 Orphan date December 2009 A cooperative database is a type of database that holds information on customers and their transactions. Many companies will contribute information to a database in return for aggregate information on the customers other companies have provided. Such databases are used for promotional mailings, credit card fraud detection and fighting E mail spam . Alternatively, the term cooperative database can be used to describe database systems that incorporate techniques to aid users beyond returning direct answers. ref Wesley W. Chu Cooperative Database Systems. Wiley Encyclopedia of Computer Science and Engineering, 2008. ref Such databases can, for example, give explanations as to why a query returns no or few results, detect and report some user misconception suggested by the query, provide justifications for returned answers, or relax query attributes to find close but non precise answers. The fundamental goal is to extend databases towards reflecting the cooperative principle , and in particular, to avoid misleading users by omission of pertinent, contextual detail.
