• Definition:

  A database is an application that manages data and allows fast storage and retrieval of that data.

    

  There are different types of database, including a modern NoSQL but the most popular meaning is a relational database.

    

  A relational database stores data in tables where each row in the table holds the same sort of information. In the early 1970s, Ted Codd, an IBM researcher devised 12 laws of normalization. These apply to how the data is stored and relations between different tables.

    

  SQL is a simplistic programming language that is used in relational databases.

    

  Oracle and SQL Server are popular commercial relational databases. MySQL is a very popular Open Source relational database.

• 8. Databases: Definition

   

  A database is a collection of information in electronic format organized in a logical fashion. Some examples of databases you may encounter in your daily life are a telephone book, an airline reservation system, and files on your computer.

   

  Some examples of databases you may encounter when using the library are the EJC, the library's collection of full-text journals; ERIC, a database of education materials; and the World Wide Web, a collection of resources on the Internet.

   

  There is a record for each unique item in a database; for example, an article in the ERIC database or a book in the XPLORE Library Catalog.

   

  Records store pieces of information about the item in fields. Databases typically have fields for for the author, title, subject, date, publisher, etc. The example below shows the fields in XPLORE, a database of materials that the XU library owns.

   We characterize a database as an organized collection of logically related data. A database can be of any size and complexity.
• We have classified a database as an organized set of related data. Organized by, we believe that the data is structured to be easily stored, manipulated and retrieved by users. Relationship means that the data describe an area of interest to a group of users and that users can use the data to answer questions on this matter.
• Hence, if we are using telephone directory then we can say that telephone diary or directory itself is database because it contains person name, address, and telephone number. But using this example we can’t define database definition because definition of database is broad vision.
