DataEase is a relational database management system (RDBMS), and is considered a rapid application development tool for developing relationally-organized, data-intensive software applications for personal computers. DataEase was created in the early 1980s by software developers Arun Gupta and Joseph Busch. The first version of the software was released in 1981¹ by Software Solutions Inc. The principals sold the company to Sapphire International Corporation of the United Kingdom in 1991. Sapphire continues to develop and market the product. There are two distinct product arcs in DataEase's history: DataEase for DOS and DataEase for Windows. As of September 2024, LegEasy9 (DataEase for Window version 9) available for purchase online at DataEase [https://www.dataease.com/dg3_FrontPage/].

In addition to simplified definition of data forms, reports and procedures, DataEase for DOS provided facilities for defining an application's user access, navigational menus, multi-format importing of data from other sources, data exporting, data backup and restoration, system documentation and user help, backing up and restoring data and integrating external programs into the application. DataEase for DOS applications provided record-level locking meaning they could be accessed simultaneously by many other users. DataEase on Unix A group in Palo Alto around 1991 came up with a product they named XDOS. It was binary-level conversion software that would transfer executable DOS files onto a prescribed Unix version and thereby DataEase for DOS became DataEase for Unix. Everything was transported so that the application made under DataEase for DOS would be ported to the UNIX environment - everything, including data. XDOS was able to be applied against an array of popular applications at the time (in the professional sense as PCs were, then, rarely seen outside of the IT Department or on desktops at work, in the library or occasionally in the home of an IT professional developer. Some of the XDOS compatible applications included DataEase, MS Word, Lotus 123 (spreadsheet) and others. XDOS was provided for specific nominated variants of the UNIX system. Not for HP but most others. The UNIX variant maker had to agree to hand over certain required technicals that HP, in the day, found impossible to agree with. Just about all variants of UNIX had no such trouble or met the criteria due to compatibility between UNIX/XENIX variants. The XDOS developers went on to develop the X Window System for UNIX. When the decision eventually came that the DataEase for DOS would not be able to port to DataEase for Windows, the arse fell from the massive worldwide user base, in 13 languages including Russian and Japanese ==References==
