1. Is this database designed for Online Transaction Processing (OLTP) or for a decision support system (DSS)?

  1. OLTP

  • b. Compaq
  • c. Open for anything

3. Do you already have the SAN?

Indexed query; Typically retrieves 50K data; Response time goal is less than 0.1 minute.

Make some use of indexes; table scans and/or multi-way joins; some ORDER BY.
Typical query touches 0.1% of the data. (Please check this with Question 8.)
Response time goal is about 5 minutes.

Large & Complex
Full table scans; multi-way joins; a lot of ORDER BY.
Each query touches significant amount (20%) of data. (Please check this with Question 8.)
Very I/O intensive. ; Response time goal is about 120 minutes.

24. Do ETL during normal operation hours.

25. Do you want to perform database administration during normal operation hours?

26. What is the space required for the “Tempdb” database

27. What is the target processor utilization percentage for the database server in %? Default is 20-30% to allow for growth over the life of the hardware. For ERP applications, 60% is considered “full”.

32. Do you want to database services on a shared environment?

33. Any additional memory required for other application / services on the server, if on the shared server?

  • a. Dell Power edge
  • b. Compaq
  • c. Other (please specify) :

36. Which processor type do you prefer?

  • a. Intel Xeon
  • b. AMD Opteron
  • c. Other (please specify) :
