InstantBDExpress is a dbExpress-based component library that emulates interface and behaviour of the BDE components, plus an array of techniques and methodologies to easily integrate these components in existing (possibly huge) applications. This combination of compopnents and techniques allows to keep backward compatibility at the application level while switching data access libraries. This way of working will also allow developers to approach a new database through a gentler learning curve, continuing to use familiar tools and techniques where possible. InstantBDExpress allows access to all databases supported by dbExpress.
