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.

At this time I would like to explain the meaning or what is information. What is the meaning of information? Information is data that has been processed so that it can be useful for anyone in need. Information can be recorded or transmitted. The experts have many other meanings of information. Information can be regarded as knowledge gained from study, experience or instruction. However, this term has many meanings depending on the context.

In particular some knowledge of the events that have been collected or from the news can also be regarded as information. In computer science, information is data that is stored, processed or transmitted. The experts examined the concept of information as knowledge gained from study, experience or instruction.

Meaning or definition of the other information is data that has been given meaning. For example, the form of a spreadsheet document (Ms.Excel) is often used to create information from data therein. Income statement and balance sheet is one form of information, while the figures contained therein is data that has been processed so that it becomes useful for anyone who can use it.

The types of informations:

Based delivery:

• Information provided periodically
• The information provided for the sudden
• The information provided at any time
• Exempt information
• Information obtained on request

Based on usability:

• Informations that adds to the knowledge, for example: events, education, activities celebrities.
• Informations that teaches the reader (educational information), such as paper describes how to raise ducks, articles about how to build friendships, and others.
• Informations based on the presentation format, information that is distinguished by the form of presentation of the information. For example: the information in writing (news, articles, essays, reviews, columns, editorials, etc.),

The characteristics of an information:

• The latest,
• Right on time,
• Relevant,
• Consistent.
• As for the functionality, information has several kinds of functions, including:
• Improve the knowledge or ability of the user,
• Reduce uncertainty in the decision-making process,
• Describe the state of something or events that occur.

That was a glimpse of the meaning or definition of What is information. If there are mistakes or flaws can be added in the comments field. May be useful.

Many opinion about definition of Information System. The system is two or more components that are interconnected to achieve a goal. Meanwhile, Information is data that has been arranged and processed to give meaning.

Here are some definitions of Information Systems:

• A system created by humans which consists of the components within the organization to achieve a goal of presenting information
• A set of organizational procedures that when implemented will provide information for decision makers and / or to control the organization
• A system within an organization that meets the needs of transaction processing, support operations, are managerial, and strategies of an organization's activities and provides certain outsiders with reports that are necessary.

As an example we take SIMPEG (Human Resources Information System). SIMPEG is an information system. Inside are some of the administrative system or commonly referred to as sub-systems. Examples of administrative systems SIMPEG: attendance system, appraisal system, payroll system, promotion system, etc.. Another example of the Information Systems Executive Information Systems, Management Information Systems and Accounting Information Systems.
In the manufacturing process, Information Systems should be planning ahead so that the system created and can later be used in accordance with the wishes of the user. Then the system is necessary in the manufacture of the Project Management Information System. Which there are methods or steps for manufacturing information systems can benefit everyone, and reduce threats to information systems.
That was a brief description of Definition Information System. If there are errors or omissions please justified or added. May be useful ..
