Simon Williams was founder, Chairman and Chief Executive of Synon Corporation, a worldwide leader in application development technology, from its foundation in 1984 until 1991. Simon conceived and developed Synon/2, the dominant development environment for IBM’s AS/400 platform, Obsydian, an award-winning application development tool and Synon/Financials, a successful financial application package. Following Synon’s move to the USA in 1990, Simon remained in the UK as Group Chairman and in 1991 left to form Dysys, a software start-up that built the Obsydian product. In 1992 Synon acquired Dysys and Simon rejoined Synon as Chief Technology Officer until the end of 1996. In 1998 Synon was acquired by Sterling Software (itself recently acquired by Computer Associates) in a share swap valuing Synon at $80 million.
Abstract Lazy Software has created the Associative Model of Data,娃 the first entirely new database architecture since the advent of the Internet. Its product Sentences娃 is a multi-user, web-enabled database management system written in Java, and is the first commercial implementation of the Associative Model. Using Sentences, customers can design and develop sophisticated database applications more quickly and with less technical know-how than has previously been possible. The high cost of application development has forced many companies to adopt packaged solutions that are not well tailored to their needs. Sentences brings custom applications back within their economic reach.

INTRODUCTION A database management system is a vital component of every computer. At the heart of every computer system lies a vital software component called a database management system that stores and manages data. Database management systems range in scale from the simple file manager found on every PC to highly complex systems capable of storing huge volumes of data and affording simultaneous access to thousands of users. According to Dataquest, $8bn-worth of database software was sold in 1999, representing 18 per cent growth over the preceding year. The market leaders are IBM and Oracle with about 30 per cent of the market each, while Microsoft has about 10 per cent, and Sybase, Informix and CA each have 5 per cent or less. Relational database technology is dominant today. The market comprises

three sectors: relational databases, which account for the lion’s share of size and growth; older pre-relational databases, which is a declining maintenance market focused on IBM mainframes; and object databases, the newest sector, which has been slow to develop and was worth less than $200m in 1998. The relational model of data was first proposed in 1970. Its commercial potential was recognised during the 1980s, and today it is dominant and ubiquitous to the point where virtually every modern data-processing application relies on a relational data base.
