1 The most common query language used with the relational model is the Structured Query Language (SQL).


Column (database)

1 Coding involved: SQL [Structured Query

Language]


SQL

1 SQL (/ˈɛs kjuː ˈɛl/ "S-Q-L", sometimes pronounced /ˈsiːkwəl/ "sequel";

Structured Query Language) is a special-purpose programming

language designed for managing data held in a relational database management system (RDBMS).


Data manipulation language

1 A popular data manipulation language is that of Structured Query

Language (SQL), which is used to retrieve and manipulate data in a

relational database. Other forms of DML are those used by IMS/DLI,

CODASYL databases, such as IDMS and others.


Data definition language - History

1 Later it was used to refer to a subset of Structured Query Language () for

creating tables and constraints


Object-relational mapping - Overview

1 However, many popular database products such as structured query language database

management systems (SQL DBMS) can only store and manipulate scalar values such as integers and strings organized within tables.

The programmer must either convert the object values into groups of simpler values for storage in the database (and convert them back upon

retrieval), or only use simple scalar values within the program. Object-relational mapping

is used to implement the first approach.


Information technology

1 The relational database model introduced a programming-language

independent Structured Query Language (SQL), based on relational

algebra.


Structured analysis - Structured query language

1 The structured query language (SQL) is a standardized language for querying information from a

database


Acronym - Comparing a few examples of each type

1 SQL: ([siːkwəl] or ess-cue-el) Structured Query Language.


Computer appliance - Appliances in industrial automation

1 EATMs (enterprise appliance transaction modules) - Enterprise appliance transaction

modules are appliances that affect data transactions from plant floor automation systems to enterprise business systems.

They communicate to plant floor equipment through various vendor automation protocols,

and communicate to business systems through database communication protocols such as JMS (Java Message Service) and SQL

(Structured Query Language).


Null (SQL)

1 'Null' is a special marker used in SQL|Structured Query Language (SQL) to indicate that a data value does not

exist in the database


Temporal database

1 A 'temporal database' is a database with built-in support for handling data involving time, for

example a temporal data model and a temporal version of Structured

Query Language (SQL).


Microsoft Access - Features

1 One of the benefits of Access from a programmer's perspective is its relative compatibility with SQL (structured query language) —

queries can be viewed Graphical user interface|graphically or edited as SQL statements, and SQL statements can be used directly in Macros and VBA Modular programming|Modules to

manipulate Access tableshttps://store.theartofservice.com/the-structured-query-language-toolkit.html

MySQL

1 'MySQL' ( My S-Q-L, officially, but also called My Sequel) is (as of July

2013) the world's second most widely used open-source relational

database management system (RDBMS). It is named after co-

founder Michael Widenius's daughter, My. The SQL phrase stands for Structured Query Language.

1 They created a new Structured Query Language|SQL interface, while keeping the same Application

field-enabled) searches for structured, Semi-structured model|

semi-structured, or unstructured data.

Language/Structured Query Language' or simply 'O-PL/SQL') is a methodology of using the Oracle

features from version 7 and other improvements, lead to one of the large-scale environment implementations of the object-

oriented database paradigm.


Tableau Software - History

1 Together, they combined a structured query language for databases with a descriptive language for rendering graphics and invented a database visualization language called VizQL

(Visual Query Language)


HTSQL

1 'Hyper Text Structured Query Language' (HTSQL) is a schema-driven URI-to-SQL query

language that takes a request over HTTP, converts it to a SQL query, executes the query against a database, and returns the results in a

format best suited for the user agent (CSV, HTML, etc.) http://htsql.org/ The HTSQL language is

implemented on HTSQL servers, which use HTSQL to convert web requests into equivalent SQL,

executes requests on a server-side database, and returns results in XML, HTML, Comma-separated

values|CSV, JSON, or YAML formats


Data Definition Language - History

1 Later it was used to refer to a subset of Structured Query Language (SQL) for creating Table (database)|tables and Integrity constraints|constraints


T-SQL

SQL#Standardization|standardized computer language that was

originally developed by IBM for querying, altering and defining

relational databases, using Declarative programming|declarative

statements


Strozzi NoSQL (RDBMS)

1 Its file name NoSQL merely reflects the fact that it does not express its

queries using Structured Query Language; the NoSQL RDBMS is

distinct from the circa-2009 general concept of NoSQL|NoSQL databases,

which are typically non-relational, unlike the NoSQL RDBMS


IBM Informix C-ISAM - History

1 It provided the underlying file storage mechanism for the popular

first generation Informix RDBMS (Relational Database Management

System), which allows data manipulation by way of the SQL

(Structured Query Language) protocol


Oracle Rdb - Data access

1 Interactive access to the Oracle Rdb can be by SQL (Structured Query

Language), RDO (Relational Database Operator), or both.


Database transactions - Transactional databases

1 In a database system a transaction might consist of one or more data-manipulation

statements and queries, each reading and/or writing information in the database. Users of database systems consider Data consistency|

consistency and data integrity|integrity of data as highly important. A simple

transaction is usually issued to the database system in a language like Structured Query

Language|SQL wrapped in a transaction, using a pattern similar to the following:


Data retrieval

1 A query language, such as Structured Query Language (SQL), is used to

prepare the queries. SQL is an American National Standards

Institute (ANSI) standardized query language developed specifically to write database queries. Each DBMS

may have its own language, but most relational DBMSs also support SQL.


SQL/XML

1 'SQL/XML' or 'XML-Related Specifications' is an extension to the

Structured Query Language (SQL) specification, which defines the use of XML in conjunction with SQL. The XML data type is introduced, as well as several routines, functions, and XML-to-SQL data type mappings to

support manipulation and storage of XML in a SQL database.

2008 support was announced for MapReduce queries within a parallel

dataflow engine, to run analytics against datasets stored in and

outside of the Greenplum Database.

the SQL|Structured Query Language (SQL) to be used with the MapReduce

paradigm from Google.


Delete (SQL)

1 In the database structured query language (SQL), the 'DELETE' statement

removes one or more records from a Table (database)|table. A subset may be defined for deletion using a condition,

otherwise all records are removed. Some DBMSs, like MySQL, allow to delete rows

from multiple tables with one DELETE statement (this is sometimes called

multi-table DELETE).

metastrings, reflect the close interaction of PeopleTools and

Structured Query Language (SQL)


Data Control Language

1 A 'data control language' ('DCL') is a syntax similar to a computer

programming language used to control access to data stored in a

database. In particular, it is a component of Structured Query

Language (SQL).

allowing the user to perform powerful searches without having to explicitly compose them in SQL, and without

even needing to know SQL
