What is the relationship between a database and a network?

Answer 1

database- centralized
net- dispersed


cheers!

Answer 2

There is no direct relationship between a database and a network. Each is a separate system: Databases can be accessed without networks; networks don't always connect to databases.

That being said... These days it's rare to find one without the other. Networks are commonly used as a communications device to get to databases.

The Internet is a good example. When you type a URL into a search box (e.g. http://www.yahoo.com ), the first thing that happens is your "www.yahoo.com" string is used as a database "key" to find the true web address - aka "dotted decimal address".

One example of a network without a database is local network in which two computers are directly connected to each other. No database is needed in this instance.

Your PC has many examples of a database without a network. Excel is one. It can be accessed via a network using an ODBC or OLE connection, but it's usually used as a simple spreadsheet (which is by definition, a database).

Answer 3

There does not have to be any relationship between a database and a network. I have several databases that reside on my computer and run from there with no need or use for a network.

But most databases can be set up to use a network. Usually you will have the actual file(s) that hold the data on a central network computer called a server. Each of the people who need to use the data have the database program (but not the data) on their computer. They then use a network to connect to the server so they can see the data. This allows multiple people to access and edit the data at the same time.

Such a relationship is refered to as "client/server". The central computer on which the data resides is called the "server". All the computers that access the data are called "clients".

There are other types of network relationships that could be set up with a database, but client/server is the most common.

Answer 4

The only relationship is that a database is on and can be shared among a network. Neither is dependent on the other but if you want to share the database, then it needs to be on a network. Below are the definitions:

"Network: a system for communication among two or more computers."

"Database: A collection of related data stored in one or more computerized files in a manner that can be accessed by users or computer programs via a database management system."

Answer 5

None at all. A network is a group of machines connected together. A database is a system for storing and manipulating data. A network can be used to access a database on one machine from other machines.
