what is a table in computer
Since 2013, restaurant chains including Chili's, Olive Garden and Red Robin have adopted them. 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. What is data communication? I) In data processing, a table (also called an array) is a organized grouping of fields. This structure is typically visually presented with an appropriate number of white spaces in front of each stub's label.[8]. All possible situations for decisions should be listed, and the action to take in each situation should be specified. For example, a heart monitoring program might sound an alarm if the pulse is too slow or the blood pressure is too weak. What is Computer? A table computer, or a table PC, or a tabletop is a device class of a full-featured large-display portable all-in-one computer with an internal battery. The University of West England has an online tutorial about decision tables. Dragging and dropping fields into a pivot table facilitates rotational, or pivotal, structural changes. the header), the row, and other structures in more complex tables. Table definition is - a piece of furniture consisting of a smooth flat slab fixed on legs. A table consists of an ordered arrangement of rows and columns. Tables are widely used in communication, research, and data analysis.

The precise conventions and terminology for describing tables vary depending on the context. Such a table typically contains several rows and columns, with the top row representing the logical variables and combinations, in increasing complexity leading up to the final function. In relational databases, and flat file databases, a table is a set of data elements (values) using a model of vertical columns (identifiable by name) and horizontal rows, the cell being the unit where a row and column intersect. Tables are used to organize data in columns and rows, like in a spreadsheet. 2) In a relational database, a table (sometimes called a file) organizes the information about a single topic into rows and columns.

A column consists of all the entries in a single field, such as the telephone numbers of all the customers. Tables appear in print media, handwritten notes, computer software, architectural ornamentation, traffic signs, and many other places.
