We looked at software packages around but decided to create our own, where we receive 98% of our drawings in electronic format we then stamp them via our software and then merge them into a database for cross reference, since we introduced this we reduced our lead time and all documents are now available to all users via a web interface. To reduce our costs on this we used MySQL and then updated to MaxDB which is free and extremely powerful.
