Double Glazing Firm Adams Glass I worked for Adams Glass on a contract basis and I was asked to look at a existing Access database developed for Adams Glass based in Southend,Essex, using a SQL Server database and MS Access front end, the database generally worked ok they wanted changes to various reports and to look into discrepencies in report calculations, and also account for the VAT change from 17.5% to 20%. This work was on-going for a number of months.
