Home -> Community -> Mailing Lists -> Oracle-L -> RE: Opinions on OLTP
Any system with online 'live' updates as opposed to saving up all the updates and running them through a batch process would be considered an OLTP application.

I am starting a Data Warehouse project, possibly using Oracle Warehouse Builder. One of the databases that I must bring together comes from IBM DB2 database. We have reverse engineered a piece of their database so that we can produce an ER diagram so that we can start understanding their data. A hindrance to us is that they do not use any constraints or referential integrity, but place all of their checks into their COBOL code. They tell me this is because they are an online transaction processing system, and that's how things are handled in that environment. I always thought that OLTP systems were airlines and such, but they, at best, have 20 data entry people. Is any database within DB2 under CICS considered OLTP, perhaps? What thresholds would you use to determine what is an OLTP system? Has anyone ever heard about putting all of the RI into code as opposed to allowing the database to do its job? It seems silly to me to put all of your checks into code because changes and maintenance would just kill you, not to mention consistency, or lack thereof.
Any insights into this would be appreciated.
