Instead of using code, the developer defines their logic by selecting an operation in a pre-defined list of memory or data table manipulation commands. In other words, instead of coding, the developer uses table-driven algorithm programming (see also control tables that can be used for this purpose). These types of tools can be used for ...
An interactive environment in which any 4GL statement may be typed and immediately processed (comparable to interactive tools like PHP or Perl) Relational database features, supporting lookup tables and the other elements of a normalized relational database; Powerful set-at-a-time operations under the control of simple imperative commands
Informix-4GL is a 4GL programming language developed by Informix during the mid-1980s. [ 1 ] [ 2 ] [ 3 ] At the time of its initial release in 1986, supported platforms included Microsoft Xenix (on IBM PC AT ), DEC Ultrix (running on Microvax II , VAX-11/750 , VAX-11/785 , VAX 8600 ), Altos 2086 , AT&T 3B2 , AT&T 3B5, AT&T 3B20 and AT&T Unix PC .
A command-line tool for executing Visual Studio created unit tests outside of the Visual Studio IDE - not really a testing framework as it is a part of the Visual Studio Unit Testing Framework. NaturalSpec: No [260] Domain-specific language for writing specifications in a natural language. Based on NUnit.
1. List scenarios for the new feature List the expected variants in the new behavior. “There’s the basic case & then what-if this service times out & what-if the key isn’t in the database yet &…” The developer can discover these specifications by asking about use cases and user stories.
A query includes a list of columns to include in the final result, normally immediately following the SELECT keyword. An asterisk ("*") can be used to specify that the query should return all columns of the queried tables. SELECT is the most complex statement in SQL, with optional keywords and clauses that include:
This is a comparison of binary executable file formats which, once loaded by a suitable executable loader, can be directly executed by the CPU rather than being interpreted by software. In addition to the binary application code, the executables may contain headers and tables with relocation and fixup information as well as various kinds of ...
The result of a command can be operated on by a succeeding command. In this way, large processing requirements could be accomplished with just a few commands. The script code as a single command would execute a manual function and in this way minimize the amount of code required to accomplish tasks. i.e. writing a search program of many lines ...
