(1) Investigate entropy encoded Database architectures(2) Develop prototype compressed relational engine(3) Evaluate its performance, using telecom or other Database information.(4) Produce design capable of transferring to commercial exploitation within three years.Progress:Following an initial theoretical and experimental investigation of a number of basic variants of strategy, a workshop was held with staff of our Industrial Sponsor (GPT PLC) which discussed the early results, and requirements for high speed databases in the telecommuni-cations domain. An analytical modelling tool has been developed which enables us to estimate the space requirements of different databases, useful in evaluating suitability of potential applications. A test-bed has been produced. First test results are encouraging, (and in line with targets). Initial datasets show compression ratios of approximately 10:1 [7:1 to 15:1] relative to their corresponding conventional database representation. Relational accesses average .5ms per tuple returned (on a 486/DX66 machine). The next milestones are to investigate alternative fundamental datastructures, second order compression, and k-nearest-neighbour access, determining the space/speed trade off for a range of sizes, and types of datasets. StaffingThe project began on 1st June 1994, with the appointment of 2 staff, Mr. Colin Fyfe (an experienced researcher), as manager, and Mr. Philip Murray a Computer Science graduate with 2 years postgraduate experience. Unfortunately we lost Mr. Fyfe in November to a lecturing post, but have recruited Mr. John Gilchrist a Physics graduate, with industrial experience and an MSc in Computer Science. Intellectual PropertyA provisional application for a patent is being filed. A report has been written collating results of our initial measurements on a conventional database system. Papers are being prepared on the architecture and on performance(awaiting filing of patent).
