What is Database?

[aayush_005]

A database is simply an organized collection of related data, typically stored on disc, and accessible by possibly by many concurrent users.

Data is the generally raw information specifically in the biological science data will include the results of the experiment.

As per specific emphasis on biological science data can be
Sequence of DNA
Sequence of protein
Three dimensional structure of protein
2D gel electrophoresis
Microarray results
RNA sequences and many other

Primary goals of databases

To collect and preserve the data
To make data easy to find and search
To standardize data representation
To organize data in to knowledge
Minimize data redundancy
Duplication of data
Stored same data in multiple files
Achieve data independence
Ability to make changes in data structure without making
changes in the programme that process the data
To organize data in to knowledge

Why to learn biological databases

To know where to submit your data, e.g., sequence
To know where to discover the biological meaning of your experimental data, e.g., microarray data
To learn how to use bioinformatics tools to access database efficiently
