Paradox for Windows applications are programmed in a different programming language called ObjectPAL. [3] Although key features of the DOS product, the QBE and the database engine, were ports keeping the DOS code, there was a major break in compatibility from PAL to ObjectPAL and in the shift to a GUI design metaphor for Forms and Reports. The ...
Data-centric programming language defines a category of programming languages where the primary function is the management and manipulation of data. A data-centric programming language includes built-in processing primitives for accessing data stored in sets, tables, lists, and other data structures and databases, and for specific manipulation and transformation of data required by a ...
System 2000 [1] [2] [3] (S2K) [4] [5] is a hierarchical database management system (DBMS). [2] Although not a relational database, S2K does have SQL support. [6] In 2007 it was noted that, while still 'running on systems cranking away in back rooms across the U.S.' it has a problem: "there's little curriculum coverage anymore at universities teaching computer science."
NOMAD provides both interactive and batch environments for data management and application development, including commands for database definition, data manipulation, and reporting. All components are accessible by and integrated through a database-oriented programming language.
Data Control Language is one of the logical group in SQL Commands. SQL [1] is the standard language for relational database management systems. SQL statements are used to perform tasks such as insert data to a database, delete or update data in a database, or retrieve data from a database.
4D (4th Dimension, or Silver Surfer, as it was known during early development) is a relational database management system and integrated development environment developed by Laurent Ribardière. [3] 4D was created in 1984 [4] and had a slightly delayed public release for Macintosh in 1987 [5] [6] [7] with its own programming language. [1]
Procedures written in unsafe languages can only be created by superusers, because they allow bypassing a database's security restrictions, but can also access sources external to the database. Some languages like Perl provide both safe and unsafe versions. PostgreSQL has built-in support for three procedural languages: Plain SQL (safe).
Perl is a family of high-level, general-purpose, interpreted, dynamic programming languages. The languages in this family include Perl 5 and Raku. [13] They provide advanced text processing facilities without the arbitrary data-length limits of many contemporary Unix command line tools, [14] facilitating manipulation of text files.
