The .dbf file extension represents the dBase database file. The file type was introduced in 1983 with dBASE II. The file structure has evolved to include many features and capabilities. Several additional file types have been added, to support data storage and manipulation. The current .dbf file level is called Level 7.
dBase (also stylized dBASE) was one of the first database management systems for microcomputers and the most successful in its day. [3] The dBase system included the core database engine, a query system, a forms engine, and a programming language that tied all of these components together.
Although it is a powerful general-purpose programming language, it was primarily used to create database/business programs. One major dBase feature not implemented in Clipper is the dot-prompt (. prompt) interactive command set, [ 1 ] which was an important part of the original dBase implementation.
DBF may refer to: .dbf, a file format introduced by dBASE database system, since adopted by other applications as well (database file) dBf, decibels above a femtowatt, a unit used to measure power and gain; Distributed Bellman-Ford, a Distance-vector routing protocol; Danmarks Badminton Forbund (Denmark's Badminton Union)
Harbour is a computer programming language, primarily used to create database/business programs.It is a modernised, open source and cross-platform version of the older Clipper system, which in turn developed from the dBase database market of the 1980s and 1990s.
xBase is the generic term for all programming languages that derive from the original dBASE (Ashton-Tate) programming language and database formats.These are sometimes informally known as dBASE "clones".
This was most common from the 1970s through the early 1990s, because GIS software developers had to invent their own geometry data structures, but incorporated existing relational database file formats for the attributes. For example, the Esri Shapefile format includes the .dbf file from the DOS dBase software.
A shape-"file" actually consisted of several files, including at the very least a .shp file to store the geometry, and a .dbf file for the attributes, the latter directly adopting the dBase format that was the dominant microcomputer database at the time (despite it being a proprietary trade secret, the .dbf format had been legally reverse ...
