Instead of showing hundreds or thousands of rows at the same time, the server is requested only one page (a limited set of rows, per example only 10 rows), and the user starts navigating by requesting the next page, and then the next one, and so on.
A common table expression, or CTE, (in SQL) is a temporary named result set, derived from a simple query and defined within the execution scope of a SELECT, INSERT, UPDATE, or DELETE statement. CTEs can be thought of as alternatives to derived tables ( subquery ), views , and inline user-defined functions.

A data type that represents a range of data can be used which are called range types. These can be discrete ranges (e.g. all integer values 1 to 10) or continuous ranges (e.g., any time between 10:00 am and 11:00 am). The built-in range types available include ranges of integers, big integers, decimal numbers, time stamps (with and without time ...
The DBC/1012 Data Base Computer was a database machine introduced by Teradata Corporation in 1984, as a back-end data base management system for mainframe computers. [1] The DBC/1012 harnessed multiple Intel microprocessors, each with its own dedicated disk drive, by interconnecting them with the Ynet switching network in a massively parallel processing system.
Horizontal partitioning splits one or more tables by row, usually within a single instance of a schema and a database server. It may offer an advantage by reducing index size (and thus search effort) provided that there is some obvious, robust, implicit way to identify in which partition a particular row will be found, without first needing to search the index, e.g., the classic example of the ...
Teradata version 13.10 and Teradata version 14 have temporal features based on TSQL2 [14] built into the database. IBM Db2 version 10 added a feature called "time travel query" [2] which is based on the temporal capabilities of the SQL:2011 standard. [1] Microsoft SQL Server introduced Temporal Tables as a feature for SQL Server 2016. The ...
