Because of which we kept countless applications and records in our home and office, store them in cupboards, draws, and all these things. The documents were thus placed in order. Which could be easily found when needed. But now it is the time we used to do paper, now we use a computer instead.

Documents are no longer stored on the computer internet but in tables or cupboards, all these data are kept in the computer in a serial wise manner, which we call a database.

If you have read the computer a little bit, then you must have heard the name of the database where the data is kept correctly and securely. If you do not know anything about the database then you do not have to worry. In this post, all the information related to the database, after listening to which you will get complete knowledge about the database and now friends, first of all, we will know what the database is.

What is Database?

The database is a museum of information. Where related information is compiled and kept. If you tell it in book language, then the database is a small part of any information. It is associated with a person’s object or place. Such as name, age, height, mobile number, home address, occupation, etc. All this is some data related to a person, data can be in many different forms. Such as text, numeric, alphanumeric, image, file, graph, etc.

When the data is organized together. Then it becomes information and a database is formed from a set of information. Data and information are organized in the database. In which information is easily accessed, managed, and updated when needed, as well as it also controls data sharing and data security, some customer care goes to store information.

Just like MS Excel after inputting all the data in it is stored in the hard disk of the computer MS uses a table to store the data in Excel. Which we divide into several different columns and rows.

So that we can easily put data in it and we can access, modify and modify it when needed, in the same way in the database, data is stored in a table that has many columns and rows. Because of which they are easy to access. There can be many such tables inside one data.

There are many websites on the internet. The database that uses, for example, takes Facebook itself, which contains many data about the user such as his name, mobile number, profile picture, friends, messages, posts, status, etc. All the details remain stored in the database present in the server if we search to get information about one person from our Facebook account. Then we get all the information about that person from Facebook’s database.

Similarly, there are many big governments, private and personal websites that use databases. Friends, nowadays databases contribute to facilities like online banking, ATM, online ticket reservation. Under this, all the information is stored in the database. Which are accessed at your convenience.

Just like wherever you have your bank account, you can get the necessary information by accessing it from your mobile with the help of this computer. And friends now know about the main elements of the database.

Key Elements of Database

 There are three main elements of any database. Field, Record, and Table. For example, we will create a student table for the children of a school, which will contain the data of subjects and marks of the names of the children of different classes. Such as the first name. Abhishek falls in class 10th, the subject is Maths. It has 80 marks. Second is the student.

Udit falls in class 10th subject. English is its mark 65. It is followed by the third number of students. Sneha falls in class 11th. It has a subject. Biology and its marks are 75.

Number four is a student. Krishna studies it in class 11th. Its subject is chemistry and its marks. Jyoti is a student of number 60, who studies in class 12th. Its subject is Hindi and its marks is 85.

Friends now know that a column of a database table about a field is called a field. Like the column in the student table above. Serial number, class, subject, marks are all called fields.

And now we know about the record, we call a report every day. Such as one two three four and five reports are given in the student table. In which the data of the student’s name, class, subject, and marks are filled, these are called records. A table consisting of a table, field, and record is a computer table. Many different but related data entry are done in this table, so friends now know about database management systems.

What is database management system?

Friends database management system, also known as DBMS. There is a software through which the user creates, defines, maintains, and controls the database. Examples of DBMS are My SQL, Microsoft Access, Oracle, Visual FoxPro, DB2.

DBMS is commonly used to maintain a database. Meaning you can insert, edit, delete, access, and update the data in the database.

For example, as you have created a database Student Table In this, you have to add details of the student of the school. So you can add via Insert if you have inadvertently given incorrect data.

So if you have to improve student details then you can do this through the edit. After a few days you come to know that the data of a student is completely wrong, then you have to delete it, you have to find out the name and address of a student from the roll number.

So from the database, you can get it. The data that is already available is called Access and you are making changes to it. So it is called update. All this work is done through the DBMS software database.

You know how many types of databases there are. This model also shows how the data is stored, organized, and implemented in the database and how its structure should be. How the data in the database are related to each other and how is the relationship between them.

Database Management System with Example?

A database management system is a type of software. Who manages the data. As it is called. database management system means a system by which data is inserted, edit, delete, update, etc. on a system. It is called a database management system. it is an end-users software through which the user creates, defines, maintains, and controls the database. Examples of DBMS are My SQL, Microsoft Access, Oracle, SQL Lite. This software is commonly used to maintain a database.

What are the types of data models

There are three types of data models. The hierarchical model, network model, and relational model is the first model to be named.

Hierarchical model

In this type of database, the data is organized as a tree structure with tables. In this model, the tree structure is followed to interconnect the records. Here the relationship is shown as a child and parent.

For example, in a college there are many courses, professors, and students, then the college became a parent and the professor and students were its children.

Network model

The second is the network model. In this type of database, data is represented as a record. And the relationship between the data is represented as a link. This model is quite powerful but also complimented as many nodes and tables are linked among them.

Relational model

And the third is the relational model, this model is powerful and simple. The structure of this model is similar to that of a table. The table is called the relation in the language of the database.

Hence its name is also a relation model. It is like a table. It contains rows and columns. In this model, the unique field is called a key. And through these keys tables are interconnected like the roll number primary key in a student table. it occurs. It is very easy to search for data and now know the advantages of the database.

Benefits of database

  1. The first advantage of a database is that more databases can be stored in less space through the database.
  2. Any information can be accessed easily.
  3. Inserting new data is easy to edit and delete old data.
  4. Data can be stored in different ways.
  5. The same database can be accessed with multiple users.
  6. Paper provides more security than files because no one can access the database without permission.
  7. Reduces redundancy Duplication of the same type of data to a lot of space, we call data redundancy. That is, the data which is given more than once is removed from the database.
  8. Provides facilities such as backup and recovery. Problems such as database reload can happen at any time, if the data is not recovered at such a time, there can be a huge loss.
  9. That is why the DBMS software provides backup and recovery facilities.

Where is the database usage?

 Where the database is used. The database is now in use everywhere, it can also be said that without a database the Internet is nothing. The database uses banking, railway reservation system, airlines, library management system, school college university, social media sites like Facebook twitter online shopping sites like Amazon, Flipkart, snapdeal, military government organizations, etc.

What is a database server?

It is a server that introduces the service of the database. A database is considered a set of those tables. The data that is stored inside can be related to an application or website. A database is the main tool where most applications and website data stores reside.

Such as name, age, height, mobile number, home address, business, etc. This is all data. Which are stored in the database server. Whenever a client requests a server, the database server provides the Reply of that request. SQL Server 2008 R2, SQL Server 2008 R2 Express, Left Server and SQL Delta for SQL Server 6, etc. are database servers.

what is database redundancy

Redundancy Duplication of the same type of data in many places, we call data redundancy. That is, the data which is given more than once is removed from the database. Storing the same data more than once in data is called redundancy.

 what is database security?

A database is a type of software. Which provides more security than a paper file because here no one can access the database without permission. Cannot access the database without password and ID.
