In computer programming, a table is a data structure used to organize information, just as it is on paper. There are many different types of computer-related tables, which work in a number of different ways. The following are examples of the more common types.
I) In data processing, a table (also called an array) is a organized grouping of fields. Tables may store relatively permanent data, or may be frequently updated. For example, a table contained in a disk volume is updated when secto are being written.
2) In a relational database, a table (sometimes called a file) organizes the information about a single topic into rows and colum. For example, a database for a business would typically contain a table for customer information, which would store custome' account numbe, addresses, phone numbe, and so on as a series of colum. Each single piece of data (such as the account number) is a field in the table. A column coists of all the entries in a single field, such as the telephone numbe of all the custome. Fields, in turn, are organized as records, which are complete sets of information (such as the set of information about a particular customer), each of which comprises a row. The process of normalization determines how data will be most effectively organized into tables.
3)A decision table (often called a truth table), which can be computer-based or simply drawn up on paper, contai a list of decisio and the criteria on which they are based. All possible situatio for decisio should be listed, and the action to take in each situation should be specified. A rudimentary example: For a traffic inteection, the decision to proceed might be expressed as yes or no and the criteria might be the light is red or the light is green.
A decision table can be ierted into a computer program to direct its processing according to decisio made in different situatio. Changes to the decision table are reflected in the program.
4)An HTML table is used to organize Web page elements spatially or to create a structure for data that is best displayed in tabular form, such as lists or specificatio.
