dBase

In 1980, dBase was published by Ashton-Tate for CP/M, the original developer of the software. It was the first database management system (DBMS) for microcomputer which included the query system which is database engine and the programming language which is forms engine. Some users said that dBase was an excellent interactive ad-hoc manipulation tool because one can easily manipulate, analyze, format and perform calculations while SQL have declarative operations which retrieves data sets from a relational database (RDBMS). dBase' first file format is .dbf. It is recommended by the Microsoft to save dBase file in Microsoft Works so that it can read by Microsoft Excel while its second file type is .dbt. For files with single indexes, dBase uses .ndx, and .mdx for files holding 1 to 48 indexes. The latest version of the legendary relational DBMS is dBase 2.8. while dbDOS 1.5 can quickly and easily work with dBASE III, IV, and V for Windows 32/64 bit operating system. dBase Classic also builds high powered data-driven applications that use the xBase languge and runs on lastest operating system of Microsoft when used with dbDOS.

FoxPro

FoxPro, a procedural programming language and database management system created by Fox Software, has been widely used even before it was turned over to Visual FoxPro. It still enjoys a strong support from its community of programmers and users up to this day. FoxPro versions 2.0, 2.5 and 2.6 are compatible with Mac, DOS and Windows 3.1 to XP. Version 2.6 is compatible also with Linux and Free BSD, SCO Unix and Windows 2000. FoxPro 2 used Rushmore, an optimizing engine that used indices to look for matching expressions, to accelerate data updating and data retrieval. FoxPro 2 was built originally on Watcom C++ that has its own extensor making it the most up-to-date technology at that time. It could access expanded and extended memory making it able to utilize almost all available RAM [DOS]. If HIMEM.SYS is not loaded, FoxPro enabled a mechanism of using interrupts when extended memory driver is absent. File formats associated with FoxPro: ACT [FoxPro Documenting Wizard Action Diagram], APP [FoxPro Generated Application], DBC [FoxPro Database], DBF [Database File], DBF [FoxPro Table], DBG [FoxPro Debugger Configuration], DBT [Database Text File], DCT [FoxPro Database Memo], DCX[FoxPro Database Index], ERR [FoxPro Compilation Error], FKY [FoxPro Macro], FLL [FoxPro Dynamic Link Library], FMT [Foxpro Format File], FPT [FoxPro Table Memo], FRT [FoxPro Report Memo], FRX [FoxPro Report], FXP [FoxPro Compiled Program], LBT [FoxPro Labeled Memo], LBX [FoxPro Label File], LST [FoxPro Documenting Wizard List], MEM [FoxPro Variable File], MNX [FoxPro Menu], MPR [FoxPro Generated Menu Program], MPX [FoxPro Compiled Menu Program], NDX [dBASE Index File], PJX [FoxPro Project], PJT [FoxPro Project Memo], QPR [FoxPro Generated Query Program], QPX [FoxPro Compiled Query Program], VUE [FoxPro 2.x View Settings], WIN [FoxPro Window Settings], TBK [FoxPro Memo Backup], SPR [FoxPro Generated Screen File], SCT [FoxPro Form Memo] and SCX [FoxPro Form].

This software was originally design for Control/Program Monitor and was later ported to the Apple II and IBM PC which is under the Disk Operating System. After several years, many companies made their own products which were Foxpro and Clipper. And these new program were much better that dBase. dBase used to make and application for window such as Web applications. An IDE with and Navigator as well as a Command Window would be the feature of dBase, with a preprocessor and an interpreter machine which is virtual. dBase intelligence is also responsible for various graphical user interface such as Form Designer, Report Designer, Menu Designer ,SQl Query designer , a Project that manages upon deploying simplified dBase application, Container, and these objects under dBase can be subclasses by simply adding new properties at the runtime.
