Example of QBE query with joins, designed in Borland's Paradox database. Query by Example (QBE) is a database query language for relational databases.It was devised by Moshé M. Zloof at IBM Research during the mid-1970s, in parallel to the development of SQL. [1]
SQL was initially developed at IBM by Donald D. Chamberlin and Raymond F. Boyce after learning about the relational model from Edgar F. Codd [12] in the early 1970s. [13] This version, initially called SEQUEL (Structured English Query Language), was designed to manipulate and retrieve data stored in IBM's original quasirelational database management system, System R, which a group at IBM San ...
SQL Server 2008 and 2012 SSRS can also prepare reports in Microsoft Word (DOC) format, while third-party report generators offer additional output formats. Users can interact with the Report Server web service directly, or instead use Report Manager, a Web-based application that interfaces with the Report Server web service.
SQR (Hyperion SQR Production Reporting, Part of OBIEE) is a programming language designed for generating reports from database management systems.The name is an abbreviation of Structured Query Reporter, which suggests its relationship to SQL (Structured Query Language).

National Statistical Office (NSO) is mandated with the following responsibilities: acts as the nodal agency for planned development of the statistical system in the country, lays down and maintains norms and standards in the field of statistics, involving concepts and definitions, methodology of data collection, processing of data and dissemination of results;
In a probability sample (also called "scientific" or "random" sample) each member of the target population has a known and non-zero probability of inclusion in the sample. [7] A survey based on a probability sample can in theory produce statistical measurements of the target population that are unbiased, because the expected value of the sample ...
QUEL is a relational database query language, based on tuple relational calculus, with some similarities to SQL.It was created as a part of the Ingres DBMS effort at University of California, Berkeley, based on Codd's earlier suggested but not implemented Data Sub-Language ALPHA.
