{sql} is about questions related to the SQL language and TeX.
SQL is an accronym for Structured Query Language. It was developed to work with data from relational databases and to modify data, tables and relations amongst them. In 1986 ANSI published its first formalization of SQL as SQL-87.
Think of a relational database as a set of tables with suitable relationships amongst them.
In La/TeX context users where interested e.g. in:
- creating La/Tex tables from queries to external databases
- providing
SQL-listings in their documents - executing
SQLduring a La/TeX compile
to mention just a few.
