In today's essay, we will know what is a database? What is Database? But what is the data before that? Know a little about this. Data is information that is processed and stored by a computer or other device.
This information can be a written document, image, video, audio, or any other kind of data. If you give the example of computer data in simple words, then whatever is stored in the files and folders of your computer, these are called data in computer language.
Similarly, when we store employee records (which is a type of data) of a company in the computer in the form of rows and columns, it is called DATABASE. Let us now tell you in a little more depth about the database, so what do you mean by database? Be fully understood. So without wasting time let's start.
what is database
A database is an orderly collection of structured information. In simple language, the systematic collecting of data is termed "Database". That's because it is created very scientifically. So that the data may be easily accessed, controlled, and updated. The primary function of a database is to make data management easier.
Let us understand with an example, imagine a university has to produce a student record of its pupils. In which they have to write down the name, class, subject and parents name of every student in a huge register with them, so that they may acquire more information about any student quickly.
So for this, by dragging rows, columns, tables in the register, they will enter the data in it number-wise in a very systematic method so that it would be easier for them to discover that information later.
Now if we save this file on the computer by writing this student record in the same systematic manner in tables, columns, and rows, then it is called a database. When data is written in this form, it is termed tabular data.
DBMS software is used to construct a database in the computer. With the aid of these tools, we may remove, update, and add store information to the database at any moment.
These computerized databases started in the 1960s. Two popular database models in this decade were the Network model (CODASYL) and the Hierarchical model (IMS) (IMS). So let's now know about DBMS.
What is Database Management System (DBMS)
DBMS or Database Management System is a program, which allows us to generate data, save data and update data in the database. Due to this users can save, access, and analyze data very easily. For this DBMS provides an interface or tool.
DBMS controls three key things.
- Database engine - which accesses, locks and updates the data.
- Database schema - It specifies the logical structure of the database.
- Data
Some Examples of DBMS
Some examples of DBMS software are listed below.
1) MySQL
MySQL was started in 1995 by Oracle. It is an open-source relational database management system (RDBMS) (RDBMS). This structure is based on query language (SQL) (SQL). It supports almost all OS systems. MySQL is well known for its excellent efficiency, dependability, and cost. It also has LAMP technology together with Linux, PHP, and Apache.
2) MS Fox Pro
Fox Pro is a DBMS, which was started by fox software. But for now, it is under the protection of Microsoft. Apart from being a database management system, it is also a text-oriented programming language.
Fox pro is a powerful database management system as well as a relational database management system (RDBMS) (RDBMS). Because it completely enables many-to-many connections between multiple DBF files.
3) Microsoft Office
MS Access is a database management system (DBMS) offered by Microsoft, which combines the relational Microsoft jet database engine with a graphical user interface and program development tool.
It is a part of the Microsoft Office suite of programs available in Professional and Higher Editions. It is used for both minor and large database development.
4) Oracle
Oracle database is a relational DBMS. It is maintained by Oracle company. This is the first database, which has been developed for corporate grid computing. This is the fourth generation of RDBMS. It is mostly used by major enterprises. Those who need to manage large amounts of data.
5) SQL Server
What is SQL Server? SQL Server, developed by Microsoft, is RDBMS, which is used to construct computer databases for MS-Windows. MS SQL server generates a database, which may be accessed by workstation and internet. It was developed to compete with oracle database and MySQL. It is a full-featured database.
Types of DBMS
There are many types of database management systems (DBMS) (DBMS). Below we are sharing with you five types of database management systems.
- Hierarchical database
- relational database
- Network database
- Object-oriented database
- document database
- Hierarchical Database
Hierarchical Database
In a hierarchical model, the data is represented in a tree structure. In this, there might be a single parent and many children for every record. Like using the example of a university, many students study in it. They have various subjects and classes.
In this case, the university is a parent and the student and others are its children. This type of model structure allows one-to-one and one-to-many connections between two different types of data. This hierarchical model was started by IBM in the 1960s.
Relational Database
A relational database is a collective group of multiple data sets. Which is represented by table, record, and column. In this tubular form, each column represents an attribute to each row, record, and each field, data value. The standard user and application programming interface (API) of a relational database is a structured query language (SQL) (SQL).
SQL is used for interactive queries for information from RDB and for collecting data for reports. This is the most popular and widely used database. We can also use it with a little instruction.
Network Database
A network database is a database type that allows multiple records to be connected to a single owner. This model is also seen as an inverted tree structure. A network database utilizes a network structure to create connections between entities.
It is mostly used in digital computers. The network database and hierarchical database are the same. But a node of the hierarchical database can have only one parent, the same network node can have relationships with multiple entities. In the network database, the child is called the member, and the parents are termed the occupier.
Object-Oriented Database
This database represents data in the form of objects and classes. In an object-oriented database (OODB), an object is a real-world item and a class is a collection of objects. It follows the core concepts of object-oriented programming (OOP) (OOP).
This database system is optional for relational databases and other database systems. In an object-oriented database, information is represented as an object.
document database
Document database (DDB) is a NoSQL database. It saves the data in the form of a document. It has grown extremely popular owing to its Document storing and NoSQL characteristics. NoSQL data storage provides a quicker way to store and find content. Document database holds the data in a key-value form.
Components of DBMS
There are five basic components of a database management system.
1. Hardware
Although it is not initially a component of DBMS, currently since the data is kept in this computer hardware (hard drive, RAM) (hard disk, RAM). So in a manner, the hardware also becomes part of the system.
When we run DBMS software, Oracle, and MySQL on our computer, our computer's hard disk, RAM, ROM, and even our keyboard from which we enter commands, it all becomes part of DBMS hardware.
2. Software
DBMS Software is the most important component. Because this offers us the interface to store, read and change data. This is the software that controls everything. It can understand the Access language and convert it into actual database commands to execute them in the database.
3. Data
Data means the content you are going to save. For which DBMS has been designed. This data can be a written document, video clip, picture, or other forms of data. The objective for creating DBMS was to store data and use data.
4. Procedures
Procedures mean procedures in Hindi. Under these steps, DBMS software is set up, installed, login & logout and taking backup, etc.
5. Database Access Language
DBAL is a basic language, through which we create commands. These commands are used to store, access, remove and update data in the database. A user can write a command in the database access language and apply it to the DBMS for execution. After which the data is translated and performed by DBMS.
6. User
Under this, there are three sorts of users. The first database administrator or DBA manages the database management system and also takes care of its security. Another programmer who creates and designs the parts of DBMS. The third end-user works to save, retrieve, update and remove data.
What is the Importance of Database
The database is vital because it is only via it that data can be managed effectively and systematically. Along with this, it also allows the user to accomplish numerous things.
Database management systems (DBMS) can handle and organize massive volumes of information within a single software application. Due to this, the efficiency of business operations rises and the time cost is decreased.
Along with this, the database management system has greatly benefited the business and the huge company. Because they use it to store many types of data. Today we use this system to manage sorts of data like employee records, accounting, library books, student information, project management, and inventory, etc.
When we perform this kind of task manually, it takes much more time than the database. Rather, once the record is generated, then you cannot simply make changes in it and it cannot be accessed by everyone. Conversely, the data saved in the database can reach any other user from anywhere. So overall in today's age
The database is very important, without it data management is a very difficult and time-consuming process.
