A Relational database is a tool which can help you store, manage and disseminate information of various kinds. It is a collection of objects, tables, queries, forms, reports, macros, all stored in a computer program all of which are inter-related.
(RDBMS) A database that allows the definition of data structures, storage and retrieval operations and integrity constraints. Data and relations between them are organized in tables.
An integrated repository of data in the form of tables that have rows and columns to show a relationship between items; information can be cross-referenced between two tables.
a database composed of linked tables which have records which are made up of fields. No one table has all the information about a record.
A method of structuring data in the form of records so that relations between different entities and attributes can be used for data access and transformation.
A collection of tables connected together in a series of relationships so that they model some small part of the real world.
A database that can be perceived as a set of tables and manipulated in accordance with the relational model of data.
A relational database is organised into tables, in which data is defined so that it can be reorganised and accessed in a number of different ways without having to reorganise the database tables.
A database with tables that must be rigidly defined before the data can be entered, and whose relationships among its records are based on common fields.
An information structure that stores data in tables that can be linked to each other for cross-referencing - for instance, a table that presents vocabulary items and their grammatical features that is linked to a table that presents grammatical features and their definitions. This format prevents the duplication of data and is the preferred method of storing complex sets of information. Compare to flat file database.
A database system in which the database is organized and accessed according to the relationships between data items without the need for any consideration of physical orientation and relationship. Relationships between data items are expressed by means of tables.
One of four database structures in which files are linked in some way.
applications: A database application where more than one file can be linked together, such as a customer list and an order list linked by a customer number. You can program all kinds of fancy functions; for example, as you type in the customer name the address and other info automatically pop into the right fields on the order form. Relational databases are made of files and produce output called reports. They are a must for serious business work. These applications, such as 4th Dimension, are harder to use and cost more than flat-file databases, but they are very powerful.
A database schema in which information is linked by common fields between several tables.
a database that is made up of normalized tables. Many logical links between tables are declared, but links can be made that were not predetermined when the database was originally designed.
A somewhat complex database which uses several tables that relate to each other in some way.
A database that contains multiple tables and other objects and has the information organized by defined relationships between tables.
A type of database which allows information in one set of database tables to be connected to information in another set of tables without requiring duplication of information. See DB2.
A type of database management system (DBMS) that stores data in the form of related tables. Relational databases are powerful because they require few assumptions about how data is related or how it will be extracted from the database. As a result, the same database can be viewed in many different ways. An important feature of relational systems is that a single database can be spread across several tables. This differs from flat-file databases, in which each database is self-contained in a single table.
A database that is organized and accessed according to relationships between items. Interdependencies among the data are expressed by data values rather than by pointers or by the location of the data items in memory providing users with a flexible approach to storing and retrieving data.
a number of tables which are linked together via fields of related data. These tables can contain any number of fields with all possible kinds of information stored in them such as names of members of staff, their e-mail addresses, etc.
Uses a logical structure to store the authentication data in a table with columns and fields. There should be no duplication of any data, helping to maintain database integrity. This can also represent a huge saving in file size, which is important when dealing with large volumes of data
the design of databases as we see it implemented in products like Interbase, Oracle and Sybase. Backed by a strong theoretical work done by E. F. Codd and Chris Date, the model follows the set concept in mathematics and relationships are represented by "link" attributes. Speaking rigorously, a database schema (structure of the objects) must be "normalized", passing through all "normal forms", namely, 1st, 2nd, 3rd, Boyce-Codd and 5st. However, in practice, a database in third normal form is accepted as normalized. One of the subjects that cause controversy until now is the representation and use of null values.
a type of database that uses the contents of a particular field as an index to reference particular records (sometimes called a multi-table database)
A database which stores data and information about relationships between data items.
See Database Marketing.
A relational database is a collection of data items organized as a set of formally-described tables from which data can be accessed or reassembled in many different ways without having to reorganize the database tables.
a database in which relations between information items are explicitly specified as accessible attributes; "in a relational database the data are organized as a number of differently sized tables"
a bunch of rectangular tables
a class of software that allows you to hold data in linked tables
a collection of data items that can be accessed and manipulated in many ways without actually changing the organization of the tables within that database
a collection of data stored in tables
a collection of data stored in tabular form (rows and columns) that follow the rules of organization first delineated by E
a collection of tables logically associated with each other by common key attribute fields
a computerized compilation of data organized into tables
a database A database is an information set with a regular structure
a database based on the relational model
a database containing more than one table, with the tables sharing data
a database divided into logical units called tables, where tables are related to one another within the database
a database in which the data is physically stored in tables A fundamental misconception
a database organized as a collection of tables
a database structured in accordance with the relational model

a database that has been designed to minimize redundant or repeated data
a database that is perceived by its users as a collection of tables (and nothing but tables)
a database that is perceived by its users to be a collection of tables
a database that is structured in accordance with the
a database that makes connections between fields in different tables
a database that presents information in one or more tables containing data about a particular entity (such as hotels, cities, or countries)
a database that stores information in tables, which are composed of columns and rows
a data management system that stores information in a series of tables consisting of rows and columns of data
a data model based on predicate logic and set theory
a decent way to represent the model in a pinch, but it's not as rich and as beneficial as an implementation of the domain in an object-oriented language
a global store of objects
a little different, in that you can share certain information between multiple records, or even multiple databases
a made up of a number of Data Tables that are connected to each other by indexed keys such as Vendor Number
a more-complex database that stores data in multiple tables that are interrelated
an efficient, reliable way to store information
an example of a data centric environment

a set of tables , also called relations
a set of tables containing data fitted into predefined categories
a set of tables from which data can be accessed and analyzed in many different ways without needing to reorganize tables or cut and paste data
