Learn Database Management Tutorials.
A database is a collection of data. That may sound overly simplistic but it pretty much sums up what any database is.
A database could be as simple as a text file with a list of names. Or it could be as complex as a large, relational database management system, complete with in-built tools to help you maintain the data.
Methods for Storing Data
Before we get into dedicated database management systems, let's look at some common methods for storing data.

Text File
Imagine we have a text file called Artists.csv, and that the contents look like this screenshot.
This is a text file. More specifically, it's a comma separated values (CSV) file. The commas separate each field within a row.
The commas give it structure. It enables us to distinguish the artist ID from the artist name. We could easily add more fields and separate them by more commas.
Each row represents a different record. In this case, each row represents a different artist.
Technically, this is a database. It contains data that is structured in a way that's easy to retreive.
With a small list like this, a text file may serve our purposes perfectly.

Spreadsheet
Another option would be to store the data in a spreadsheet using spreadsheet software (for example, Microsoft Excel). That way, we could do some extra things with our list (such as format it, or sort by artist name, etc).
A spreadsheet program like Excel makes these tasks relatively easy to do. Also, programs like Excel organize the data into rows and columns, making your data easier to comprehend.

Database management systems like this are purpose built for data storage and retrieval.
Learn SQLite
SQLite is a relational database management system contained in a C library. In contrast to many other database management systems, SQLite is not a client–server database engine. Rather, it is embedded into the end program. Best for mobile application.
Learn ORACLE
Yes, Oracle is king in the race for most popular databases. Why? – its really famous among all developers, easy to use, well-written documents, amazing new features ( JSON from SQL, Robust Code using Constants for Data Type Lengths feature, long name support, list tag improved, etc).
