Database

I hope you are well. My topic is Database, and first we will see what a database is. A database is a collection of relevant data to be electronically stored and can include numbers, photos, words, images. A software used to store this data called database management systems. This data sets are storedseparately in any computer systems. There are many types of databases, of which we will look at a few:

• SQL databases
• New SQL databases
• Graph databases
• Object-oriented database
• Computer network database
• Distributed computing database
• Document database

These are some types of databases, and among them, the most commonly used is the SQL database, which is a full-form structured query language. A relational database is one in which data is stored in the form of tables. Tables are basically collections of rows and columns to stored data in a specific order. SQL database is the most widely used database, sqlServer, MySql, PostgreSql and Oracle database are some exaples of SQL Database.

Along with the NoSql database is a database in which the data does not stored in rows and columns, here the data is stored in different objects, an example of which is Redis database and Mongodb database.

And another one is Graph database is a database in which a graphical representation of data is stored. It display the relation of nodes and eges and thier relation with each another. Neo4j and ArangoDB are examples of graph database. There are many other types of databases and further their examples whch we will discuss in later. I hope you find this information useful.
