What is a Database ?

Recommended Posts

wut is a database and wut is it used for?

<{POST_SNAPBACK}>


database means a way to storage, retrieve and manage data. Every sort of data.

 

databases storage data following a well definied structure.

 

That "structure" aids to mantain data in order and find data you desire.

 

database means nowadays "computer-based database", but database is a generic term that represents every form of structured information. A file folder in an office is a "physical database", becasuse let you stock files and find speedly data you want, due to its subdivision of file in folders.

 

Software databases follow the same approach. They let you cluster elementary information in "tables", collections of similar datas. A database can hold many tables linked each other to build a structured knowledge of a specific fact.

The database, for a forum, will store the data the user puts in. This post I am making is being stored in a database.That's what a database is... in a nutshell. :)

how a database works:well, it's a collection of tables.for example, for this forum, there is a table users.this table has fields like: nr, name, date joined, msn, ...and then there is a table posts. and this posts has fields like:date, user (which refers to the nr in the users table, so you can find out everything of the user who posted it), text,...that's how a database works.cool thing is that you can do searches in a database.for example, you can search for all the posts that have usernr 110. select text from posts where userid=110that's a bit like the 'find all posts by this user' function you got on this forum
