Runs dBASE IV applications on the Macintosh
dBase (also stylized dBASE) was one of the first database management systems for microcomputers, and the most successful in its day. 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. Originally released as Vulcan for PTDOS in 1978, the CP/M port caught the attention of Ashton-Tate in 1980. They licensed it and re-released it as dBASE II, 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, 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. This changed with the disastrous introduction of dBase IV, whose design and stability were so poor that many users switched to other products. 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: Borland purchased Ashton-Tate Microsoft bought Fox Software, and Computer Associates acquired Nantucket.
dBase IV
Introduced in 1988, after delays, 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, 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 but with a focus described as "designed for programmers" rather than "for ordinary users."

DISK TRANSFER SERVICE: (OPTIONAL)
If you are the winner of the auction and would like the software also on a 1.4 MB disk (so as to allow this software to run on a slightly newer Mac such as a 1998 iMac that may not be able to read 400K/800K disks), I am offering a disk transfer service to transfer this software to a 1.44 MB Floppy so your newer computer can read the media. I make no guarantees that that the software will work perfectly on a Mac too new for its design, but will give you the option to try it. The cost of this transfer service is .00 per 1.4 MB floppy disk used.  This is an optional fee and you will get both formats: the original low density disks that came as new plus the 1.4 MB copy.
