By early 1984 "InfoWorld" estimated that Ashton-Tate was the world's sixth-largest microcomputer-software company. dBASE II reportedly had 70% of the microcomputer-database market, with more than 150,000 copies sold. Ashton-Tate published a catalog listing more than 700 applications written in the language, and more than 30 book, audio, video, and computer tutorials taught dBASE. Other companies produced hundreds of utilities that worked with the database, which Ratliff believed contributed to Ashton-Tate's success; "You might say it's because the software is incomplete. There are 'problems' with dBASE—omissions for other software developers to fill". He noted that "If they weren't with us, they'd be against us", and Cole promised to always notify third parties before announcing a new product or changing dBase's marketing. In May the company announced, and in July shipped, dBASE III as the successor to dBASE II. July also saw the release of Framework, an integrated office suite developed by Forefront Corporation and funded by Ashton-Tate. These were the company's first products released with copy protection schemes in an attempt to stop software piracy.
