Thought Question

What is a database?

Define each type below.

1) Single-User Database
2) Desktop Database
3) Multi-User Database
4) Workgroup Database
5) Enterprise Database
6) Centralized Database
7) Distributed Database
8) Transactional Database
9) Data Warehouse Database


Definitions:

Single-user databases are stored information created for an individual’s needs and are created solely for that user. Examples of these databases may be in the form of personal financial records or other information that is private.

Multi-user databases are places where information is stored where multiple people will access and alter the information. Examples may be data storage for project development teams; these are generally used for small groups, but are not limited in number of users.

Workgroup databases are places where large groups of individuals can freely modify and change information. A great example of workgroup database use is in open source software. Information is open for public access to alter or use the information.

Desktop Databases are systems like Microsoft Access that make data storage and retrieval simple and can be used from a simple desktop computer.

Centralized databases are places where information is stored from a variety of different locations to one location. An example of this is a county library catalog. Each individual library in the county has its own information, but that information is kept in a single location so all the catalogs can be searched and information is easily accessible.

Data Warehouse Databases are just as their title sounds a place to store large amounts of data. Information that is stored in these areas is prepared by screening, formatting, and editing the data so that it is easy to retrieve and use.
