1. A structured body of linked data.
2. A Database is a structured collection of records or information that's stored in a computer device. The structure is realized by organizing the data.
Hence what we notice from these definitions is that a Database is simply data. Now this data can be text, pictures, articles and other content, audio, or speech. It doesn't need to simply be text. Another important thing is the tables and records are related.
Over the years various kinds of databases have been developed but nowadays the commonest type is the relational database. The relational database has tables of matching information and all these tables are linked together.
An example of the relational database is in an order procedure. Tables may incorporate customers, orders, order items and products. The customers table will have the customer's name, number and shipping location. The order table should include the customer as well as the order number plus the order date. The order item will be the products that they are buying with all the cost and additional details.
The customer table relates to the order by using a customer ID and the order is related to the items in the order using an order ID.
In this manner you can easily perform queries such as what products a consumer has decided to buy and when we look from the products side we will find which customers purchased that product. Here is where the relational aspect is very useful.
A database is definitely important for an organization to run effortlessly but databases may also be discovered as a back end to most software programs that people purchase. For example, a tool for emailing clients or gathering email addresses is going to have a database for its framework.
The best thing about a Database over a spreadsheet such as Microsoft excel is that all data can be related together hence we could query any record against some other record. Additionally every record is just entered once, in a single table, thus we don't have the problem of information not being updated properly.
The part that confuses most people who want to learn how to create a database is how to join the tables of information together. The tables actually link together quite logically and after a little practice it becomes fairly easy.
