The market did not increase much for Btrieve and it did not see wide adoption due to these issues. When the company was acquired by Novell, SoftCraft had been working on a product called XQL, an SQL interpreter designed to better deal with industry standard SQL, which the Xtrieve package was not fully compliant with. This became the basis for NetWare SQL, which was initially released in 1989, and was a bare-bones SQL interpreter which implemented the base IBM version of SQL. By 1994, Novell had largely given up on attempting to make NetWare into a complete alternative operating system, and started selling off many of the companies it had acquired only a few years earlier. They had minimally promoted Btrieve, largely due to the delay (24 months) in releasing version 6. Negotiations between The Woodward's and Novell were entered into, and after two years Novell announced (26 Jan, 1994) that it was going to transfer ownership of Btrieve to Btrieve Technologies, Incorporated (also known as BTI). On 29 April 1994, the transfer was completed and Nancy Woodward became the Chairman of BTI and Doug Woodward was made the Chief Technical Officer. The CEO position was given to Ron Harris, a former employee of Texas Instruments, and one of the founding employees of Citrix Systems, Inc. where he was employed first as Director of Strategic Planning, then as Vice-President of Marketing, and finally as the Product Group Vice President. Btrieve was totally rewritten, and on 1 July 1994 Btrieve 6.15 for DOS, Windows and OS/2 was released. Novell SQL was renamed to Scalable SQL reflecting the change in ownership of the company. In 1995, version 6.15 was released for Novell NetWare, Windows NT Server and for Windows NT/95, and thus became a cross-platform database product. The concept of a Micro Kernel Database Engine (MKDE) was introduced in this version. In 1996, the company renamed itself to Pervasive Software, and their product to Pervasive.SQL. In 1997, the company went public. They did this in order to allow greater penetration of the relational database market and to re-align as an SQL vendor, though they are still marketing and developing Btrieve. Pervasive completed its IPO in September. The company continued using the MKDE in version 6.30. In 1997, Pervasive released ScalableSQL 4.0, a relational database product, and Btrieve 7.0.
