Database Explained
Databases are seemingly very complex and rather hard to
explain but here goes. Below is Wikipedia's description......
The central concept of a database is that of a collection
of records, or pieces of knowledge. Typically, for a given
database, there is a structural description of the type of
facts held in that database: this description is known as a schema.
The schema describes the objects that are represented in the
database, and the relationships among them. There are a number
of different ways of organizing a schema, that is, of modeling
the database structure: these are known as database
models (or data models). The model in most common use
today is the relational
model, which in layman's terms represents all information
in the form of multiple related tables each consisting of rows
and columns (the true definition uses mathematical
terminology). This model represents relationships by the use
of values common to more than one table. Other models such as
the hierarchical
model and the network
model use a more explicit representation of relationships.
WOW! I understand databases and I'm confused! My own description is a very basic, almost everyone knows
what a spreadsheet is. It's a group of columns and rows where each cell is
a place to store data. A database is just a group of
spreadsheets called TABLES that can be queried, sorted and
rearranged to find specific
data instantly or joined with other TABLES that have similar data. In
other words spreadsheets on Steroids.
Their are numerous Brand name and types of Databases with
varying costs involved like MySQL, PostgreSQL, MS SQL2005,
Oracle, DB2, FoxPro, Paradox, dBase and many many others. Some
uses for Databases are listed below. These are not all
the reasons to use databases but ONLY a few examples
