Given that Software AG is still gaining new licences for Adabas, that it is directly targeting users of IMS and VSAM to move to Adabas, that Adabas revenues are growing at between 20% and 30% per annum, and that the company has aggressive plans for introducing new features and capabilities (including real-time replication, multi-media data and storage support, an XQuery Gateway, and browser-based management facilities) during 2005, then we think it would be fair to say that if Adabas is a legacy database then the term 'legacy' ceases to have any useful meaning (if, indeed, it ever did).
