Organized Files
A computer database, or simply called a database, is a collection of information and data stored in a computer system. Databases vary depending on how the information is stored. A database system is important in handling an organization’s day-to-day activities, especially in storing information and important documents.
The program that manages the database is referred to as the database management system or DBMS. Among the most popular systems include Microsoft Access, Oracle, Microsoft SQL Server, MySQL, and File Maker. These databases are far more complex than a text file or a spreadsheet, as they have the ability to relate the records across different tables.
The flat (or table) model consists of a single, two-dimensional array of data elements, where all members of a given column are assumed to be similar values, and all members of a row are assumed to be related to one another. For instance, columns for name and password that might be used as a part of a system security database. Columns of the table often have a type associated with them, defining them as character data, date or time information, integers, or floating point numbers.
A spreadsheet program similar to Microsoft Excel is also a form of database. This type of program also allows the user to easily organize the data. For example, the user can arrange the records by surname or by first name. The items are organized in both rows and columns that make the record easier to understand.
Another advantage in using a database is that it allows for data manipulation. Thus, some database systems are able to retrieve data that matches a certain criteria, delete or update the records, as well as perform complex calculations that concern the data.
Among the most basic examples of a database is the text file. One notable feature of text files is that it does not support formatting of any kind. Without the excessively complex systems, hierarchies, formatting and methods that the average computer user knows nothing about, the text file becomes a fairly straightforward way of organizing your files, streamlining data enough that it can be read by any kind of system. This information is useful in many tasks, such as sending email.
