AND a response to this post

The relationship between the database and information system is that the database would reside on the information system (server or computer). According to Mindtap, an information system is a system that provides data collection, storage, and retrieval. It is composed of hardware, the DBMS, people, and procedures. This relationship has a profound impact on the performance of the database management system as the information system is where the DBMS resides. If you want adequate performance on the DBMS you cannot have the DBMS running on a Pentium III you will need the proportionate hardware to support the load that will be placed on it.

It is impossible to produce good information from poor data?

I think that it is possible to produce good information from poor data with a few dependencies. If the data is poor, for what reason? Was it captured in an unorganized manner? I feel there is always a way to pull information from poorly organized data, it is just more work that if the data was not poor. For instance, data can be pulled from a corrupt hard disk drive, but it take a little bit of work.
