Databases

We have decades of experiences of designing, developing, and deploying database-based solutions from small embedded systems up to IBM mainframes. Examples include:

• Internally-developed DB-based system for services and CRM on PCs pre standard-PC era (end 70s, early 80s).
• Many 4th Dimension (4D) - based systems including a - for the time quite advanced - bed-booking system for the World Championship for Twelve's, America's Cup. Multiple users, local area networking, remote access - on Macintosh computers in 1988 (yes, 1988).
• Troubleshooting activities and interface development and coordination in DB2 - based system on IBM main frames with thousands of users.
• DBM-based, HP-UX environment, including use of shared memory
• Internally-developed (with formal library methods, well-documented, used by many developers) in embedded single-board computers (primarly using C and parts in assembly, with also access from shell scripts like ksh and perl, and CGIs for web, Perl, PHP).
• Same for high-performance real-time system consisting of sixteen parallel computers.
• Later focus is more on open solutions, good scalability, web-based access - (e.g.) MySQL.
• Web interface for FileMaker.
