Information systems are not made arbitrarily. In making the necessary principles and mature concept that the system is working as expected in practice. Not infrequently a system when applied to raw information, the absence of the principle of the right to good information system creation. Kalli on this post, I will discuss the principles of a good system.
Here are some principles of a good system:
1. Availability, include:
Documentation of complete data, where every business activity can be recorded in an information system. Minimize system failures, prevent the system can run in line with expectations.
2. Security
Giving a password, one form of security of a system, required security password to prevent misuse of the data.
Pposisi safe computer, it is more directed on computer and network layout.
Put safety alarm, to prevent hardware theft. Such as: monitors, cpou, etc..
Data control, monitoring data regularly can reduce the risk of security problems of data stored on a system.
3. Can be maintained
Performance measurement system and the periodic review system, these two things are related. Because a review of the system can be used routinely to monitor the data as well as measure the performance of the running system. So the data information system management knows what to do with the system going forward.
4. Integrity
Verification of the data, the process of checking the data when the data is entered into an information to come out. Verification of the data takes time and effort, which is conducted by the management system.
Duplicate data checking, to reduce data redundancy (duplicate data) needs to be done gradually. Can also be categorized as a data control. It's just that it aims to manage database systems.
That was a brief description of the principle of a good system. Hope it helps and if there is an error can be input via the comments below. Thank you.
