Retro Database dBASE Making a Comeback? Ok, that report is due soon, so I'm going to fire up dBASE to run some reports, export the data into Lotus 1-2-3 and summarize everything with WordPerfect-while listening to Wham! And Foreigner, of course.
dBase (also stylized dBASE) was one of the first database management systems for microcomputers, and the most successful in its day.[2] The dBase system includes the core database engine, a query system, a forms engine, and a programming language that ties all of these components together. dBase's underlying file format, the .dbf file, is widely used in applications needing a simple format to store structured data.

dBase was originally published by Ashton-Tate for microcomputer operating system CP/M in 1980, and later ported to Apple II and IBM PC computers running DOS. On the PC platform, in particular, dBase became one of the best-selling software titles for a number of years. A major upgrade was released as dBase III, and ported to a wider variety of platforms, adding UNIX, and VMS. By the mid-1980s, Ashton-Tate was one of the 'big three' software publishers in the early business software market,[3] the others being Lotus Development and WordPerfect.

Starting in the mid-1980s, several companies produced their own variations on the dBase product and especially the dBase programming language. These included FoxBASE+ (later renamed FoxPro), Clipper, and other so-called xBase products. Many of these were technically stronger than dBase, but could not push it aside in the market.[4][5] This changed with the disastrous introduction of dBase IV, whose design and stability were so poor that many users switched to other products.[6] At the same time, there was growing use of IBM-invented SQL (Structured Query Language) in database products. Another factor was user adoption of Microsoft Windows on desktop computers. The shift toward SQL and Windows put pressure on the makers of xBase products to invest in major redesign to provide new capabilities.
In the early 1990s xBase products constituted the leading database platform for implementing business applications. The size and impact of the xBase market did not go unnoticed, and within one year, the three top xBase firms were acquired by larger software companies:
By the following decade most of the original xBase products had faded from prominence and several disappeared. Products known as dBase still exist, owned by dBase LLC.
History[edit]Origins[edit]
In the late 1960s, Fred Thompson at the Jet Propulsion Laboratory (JPL) was using a Tymshare product named RETRIEVE to manage a database of electronic calculators, which were at that time very expensive products. In 1971 Thompson collaborated with Jack Hatfield, a programmer at JPL, to write an enhanced version of RETRIEVE which became the JPLDIS project. JPLDIS was written in FORTRAN on the UNIVAC 1108 mainframe, and was presented publicly in 1973. When Hatfield left JPL in 1974, Jeb Long took over his role.[12]
While working at JPL as a contractor, C. Wayne Ratliff entered the office football pool. He had no interest in the game, but felt he could win the pool by processing the post-game statistics found in newspapers. In order to do this, he turned his attention to a database system and, by chance, came across the documentation for JPLDIS. He used this as the basis for a port to PTDOS on his kit-built IMSAI 8080 microcomputer, and called the resulting system Vulcan (after Mr. Spock on Star Trek).[13][14]
Ashton-Tate[edit]
George Tate and Hal Lashlee had built two successful start-up companies: Discount Software, which was one of the first to sell PC software programs through the mail to consumers, and Software Distributors, which was one of the first wholesale distributors of PC software in the world. They entered into an agreement with Ratliff to market Vulcan, and formed Ashton-Tate (the name Ashton chosen purely for marketing reasons) to do so. Ratliff ported Vulcan from PTDOS to CP/M. Hal Pawluk, who handled marketing for the nascent company, decided to change the name to the more business-like 'dBase'. Pawluk devised the use of lower case 'd' and all-caps 'BASE' to create a distinctive name. Pawluk suggested calling the new product version two ('II') to suggest it was less buggy than an initial release. dBase II was the result and became a standard CP/M application along with WordStar and SuperCalc.[15]
In 1981, IBM commissioned a port of dBase for the then-in-development PC. The resultant program was one of the initial pieces of software available when the IBM PC went on sale the fall of 1981. dBase was one of a very few 'professional' programs on the platform at that time, and became a huge success. The customer base included not only end-users, but an increasing number of 'value added resellers', or VARs, who purchased dBase, wrote applications with it, and sold the completed systems to their customers. The May 1983 release of dBase II RunTime further entrenched dBase in the VAR market by allowing the VARs to deploy their products using the lower-cost RunTime system.
Although some critics stated that dBase was difficult to learn, its success created many opportunities for third parties. By 1984 more than 1,000 companies offered dBase-related application development, libraries of code to add functionality, applications using dBase II Runtime, consulting, training, and how-to books. A company in San Diego (today known as Advisor Media) premiered a magazine devoted to professional use of dBase, Data Based Advisor; its circulation exceeded 35,000 after eight months.[16] All of these activities fueled the rapid rise of dBase as the leading product of its type.

There were some legal 'difficulties' with Ashton-Tate, publisher of the dBase II software.[25][26]
dBase III[edit]

As platforms and operating systems proliferated in the early 1980s, the company found it difficult to port the assembly language-based dBase to target systems. This led to a re-write of the platform in the C programming language, using automated code conversion tools. The resulting code worked, but was essentially undocumented and inhuman in syntax, a problem that would prove to be serious in the future.[citation needed]
The resulting dBase III was released in May 1984. Although reviewers widely panned its lowered performance, the product was otherwise well reviewed. After a few rapid upgrades the system stabilized and was once again a best-seller throughout the 1980s, and formed the famous 'application trio' of PC compatibles (dBase, Lotus 123, and WordPerfect). By the fall of 1984, the company had over 500 employees and was taking in $40 million a year in sales, the vast majority from dBase products.
dBase IV[edit]
Refx nexus mac torrent download. Introduced in 1988,[27] after delays,[28]dBase IV had 'more than 300 new or improved features.' By then, FoxPro had made inroads,and even dBase IV's support for Query by Example and SQL were not enough.
Five years later,[29] after the top 3 implementations of the dBase language were bought by Microsoft, Borland and Computer Associates, a version called 'dBase PLUS 8' was released; it 'can be used to build .. Web .. and server-based applications.'
Along the way, Borland, which had bought Ashton Tate, brought out a revised dBase IV in 1992[30] but with a focus described as 'designed for programmers' rather than 'for ordinary users.'
