Accompanying the ever-growing reliance on computers within contemporary organisations, the task of software maintenance is, increasingly, becoming a resource burden. The author has identified that there is a need for proven techniques to allow the modelling of flexible/changing user requirement, to enable systems to cope with requirements creep without suffering major code change and associated down-time from rebuilds of the database. This study ascertains the applicability of extension to current data modelling techniques that allows innate flexibility within the data model. The extension of the data model is analysed for potential benefits in the provision of such a dynamic/flexible base to realise 'maintenance friendly' systems and, in consequence, alleviate the cost of later, expensive maintenance.
