5. Is Enterprise Edition better than Standard Edition?

A: The Enterprise Edition is fully functional and provides higher reliability and performance, but it also means more software and hardware costs. We recommend that you determine the version based on your actual needs. The most suitable version is the best.

6. What is the Oracle ordering method?

A: There are two ways to order by number of users and by CPU, in which the order by CPU is also called the unlimited user version.

Official English definition: Named User Plus: is defined as an individual authorized by you to use the programs which are installed on a single server or multiple servers, regardless of whether the individual is actively using the programs at any given time. A non human operated device will be counted.

A: The minimum number of users of Oracle official versions is:

Individual version: 1 user * PC count

Standard Edition 1 = number of servers x 5

Standard Edition = server CPU x 10 Users

Enterprise Edition = server CPU x 25 users;

Users should order according to their actual number of users, and not less than the minimum number of users required by the corresponding version.

A: If the number of users accessing Oracle is large, or the number of users cannot be estimated, the order should be made according to CPUProcessor.

12. Is the fee charged by CPU High?

A: Generally, the cost of 1 CPU is about 50 users. Therefore, if the number of users is greater than the number of CPUs * 50, it is more economical to order by CPU.

13. do Internet or B/S architecture applications have to be subscribed to by CPU?

A: Not necessarily. If the number of users accessing the Oracle database is estimated, and the number of users is not much smaller than the number of server CPUs * 50), you can also order the number of users.

Q: tax-included price after discount

P: unit price not taxed per user or CPU)

N: Number of users or CPUProcessor;

D: discount % off). The initial discount is 30% off.

22%: one-year standard service fee, with 7% Product Support and 15% upgrade guarantee;

C: Media fee. Currently, the fee is RMB 580/set.
