Business intellgence systems are the systems with the startegic plannig in the company. It represents the tools which is used to make the reports. Generally organisations store raw data in the database. It is difficult to process this raw data to get the meaningfull information. In this cases business intelligence are very much helpfull in data mining and making necessary reports accroding to the requirement of the organisation.
On the other hand knowledge managment systems are the systems which is used to store the information of the organistion or even anything might be personel also. This systems stores data init and using business intelligence tools we will get/retrieve the data from this system.
And the expert systems are the systems which actually work like the human experts / human brains. it is mainly used for the decision making purpose using artificial intelligence. This redues the risk of making human errors in anything.
- By employing this tools organistions efficiency will be incresed because of the computing and storing capabilities of these systems. This results in the faster execution of work, so that the tasks will be completed within the stipulated and less time.
- The cost to setup this systems are also moderatly high. Because first we need to get the licenses for this tools and need to have or setup one seperate team to manage this systems. This becomes somewhat costly for both the managers and aswell as to the business users becase they also must need to install seperate set of software to access this data fastly.
- There is not a seperate measure like only more data willl leads to the optimal performnce of th system. If there is less data the system will not be fully usable. But with the more data the systems will work more effectively and runs in their maximum speed.
