Database: Meaning and Uses

Understanding database meaning is important to using databases. Although databases were once used by only the most advanced computer programmers, they have become part of regular Internet use and everyday life. There are many different types of databases, and they can be used in a variety of ways to make accessing information more efficient.

What Is A Database?
In the simplest terms, a computer database is a program that catalogs information for retrieval. A basic form of a database is a spreadsheet. Spreadsheet programs allow you to catalog information easily. However, you need database management so you can find relationships in the data on the spreadsheets. Databases go the extra step and allow you to access information in new ways and apply the information in different formats, such as Web pages.

Database Varieties And Uses
Databases allow you to collect and organize information. They are easier to use than spreadsheets because they allow you to update information across the board, and they also help reveal connections between data on different sheets. Database programs like Microsoft Access can be used for personal or business use to keep track of information, like names and addresses, orders or projects. These databases are defined as "desktop databases" and can be purchased as software for personal or office use.

Server databases are used for more complex computer functions. They are used by organizations to manage large amounts of data. They also allow this data to be updated in real time. Server databases are hosted on servers offsite because they need a lot of processing power to manage that much information at once.

Although databases are commonly used to access data, they are also used frequently in order to make Web sites run. The information stored in a database populates Web pages, and users can update a Web site quickly and easily by adding content to a database using an HTML interface.

Database Management Systems
Database management systems offer a way for computers to access the information in databases and update them. They are typically abbreviated "DBMS." They work with the database and instruct it to perform tasks based on the user's input. These tasks can include adding new data to categories, adding new categories to the database, deleting old information and improving upon the existing information.

Tasks are carried out through the DBMS using SQL commands. These commands allow multiple users to make changes to the database without crashing the entire system. There are different forms of commands used in SQL, including data definition language, data manipulation language, data query language, data control language, data administration commands and transactional control commands.
