Why we use database for storing data

In the Database, we store our important data in every field. The database is the most useful and important part for everyone. If we don't have a database then we don't know where to store our most important data and also if we don't have a database then we can not able to back up our important data. In short, if we don't have a database then we don't know where to store and without it the world is nothing. 

We can use databases everywhere let's discuss some of them we use the database in grocery stores we use the database in schools, colleges, and universities where we store a large amount of student data in a database if we don't have a database in the education field then we are not able to know when the student is taking admission in the college and much more. At the start when we don't have the data the teachers used the registers for storing the data this is the most difficult task and also it takes much more time.

For reducing this problem the concept database arrives which make people's life easier in the database you can save as much as you can and you can fetch that data at any time without any difficulty and also your time will not waste. The database is also used in banks, bus stops, railway roads, etc.

The data we have available is in the structured form we can access it and also we can store that data in the system. Most of the data we stored in databases is in the relational form meaning the data is available in the table which has rows and columns. We use this format because we can easily access that data update the data change the data and delete the data. We have many types of databases where we can store data let's discuss them one by one.

Types of Database

File Based for storing

File Based is also a Database where we can store the data. But this is a very old storage system. In this storage system you can store the data in the files at that time there is no concept of any cloud storage or any other storage.

NoSQL Database for storing

This is also used for storage in the database we can store huge amount of data but at the same time, it not just store the table data but also it stores all the data available in other formats. This Database has four types which are Key value storage, Graph Database, Wide Column store, and document-oriented database. It doesn't only need to store the data in a structured format but also it can store unstructured data. If you add or remove the data it does not affect the other data meaning it is scalable. 

Relational Database for storing

In a relational database, we store data in a table that consists of columns and rows. The data we store in the table is easily accessed and modified as compared to the others database.

Cloud Database for storing

In Cloud Database we store the data in the cloud. If we store the data in the cloud then we don't need to worry about storage. If we store the data in the cloud then we can access it from anywhere. If you store your data on your personal computer and you need to access the data but at that time you are not at home then you can do nothing. So for removing this problem cloud computing come place. In cloud computing, you can save your data in the cloud and if you are not at home you can access that data.

Let's take the example of cloud computing. the most popular cloud computing is Google Drive. You can store your text file as a mean article that is written in word or from any other source. You can also store the animation like videos. You can also store your code files in Google Drive and access them from anywhere. Google Drive also provides you the free storage. Amazon web services also provide cloud storage.

Personal Database for storing

In this database, only one person stores a record it's specially designed for one user. Many software provides this facility and the main advantage of this database is that we can easily manage the data we don't need any special trading to understand the software you can easily handle this kind of software. Also, it is designed for a single user then it takes only a small space.

Distributed Database for storing

As you can see it name is distributed. Distributed means we have a piece of paper we have to divide that paper then we equally distribute the paper will all. Same in the distributed databases we have data and we have to store it in different locations. So for this, we use distributed database. There is also a reason behind the usage of this database we also store replicas in different locations and if we lost data stored in one location at that time we don't need to worry about anything we can access the data stored on another database and use it.

Hierarchical Database for storing

In a tree-like structure, the data we have is stored in the tree format. Let me tell you in tree format you can store data like the parent and child method. In the Hierarchical method we store records every record of a child can have only one parent same like real life. But if we talk about the opposite side then one parent has multiple children.

Enterprise Database for storing

This database is designed for different users and is used for managing a huge amount of data. This database is designed for that more than one user can access it at the same time and it also helps the users to save time. The main advantage of this system it allows the user to perform queries at the same time and get their results. In the other system, only one user can have access to a database but for reducing it enterprise will take place.
