What is a data base ?

One of the most common terms in the computer world is a database. You may be wondering what a database is. With the introduction of this concept in applications, a revolution was create in their development. It won’t be easy to find applications that do not use a database almost today. If you want to know more about the data base and its applications, we invite you to continue this article.

What is a database?

A database is a collection of organized information stored together in a specific order and rules. In other words, when we put our data together in an orderly and organized way, we call it a database, database, or database. According to this definition, a phone book or a list of goods in a store’s warehouse is also considered a D9%25BE%25D8%25A7%25DB%258C%25DA%25AF%25D8%25A7%25D9%2587_%25D8%25AF%25D8%25A7database.

In computer science, a database is where information about software, website, etc., is stored. Also based on the rules it uses to organize information, the database makes it much easier to access and manage stored information. So using a database allows us to store our information accurately in a specific order. By doing this, we can access part or all of this information in the shortest time. Using the Database also gives us other benefits such as data independence, eliminating duplicate processes, increasing security, data backup, etc.

A simple example of a database

Now that we know what a database is, we will look at a simple example of it. Imagine you are going to rent a house in one of the areas of Tehran. Also to do this traditionally, you should consult a real estate consultant in that area. So the real estate consultant will provide you with a list of homes for rent in that area. This list contains various information about rental houses in that area, including the owner’s name, home address, rent, deposit amount, and so on. In this example, the list provided to you is a database of rental home information in that area.

Databases in the computer world

One of the most common uses of Databases is information management in software. Also in this section, we will mention an example of databases in software. For this purpose, consider the site :

This information can include displayable and non-displayable information for users. Thus, the sum of these tables, each of which holds different properties of the entities, constitutes the site database. Also, each of these tables is designed with proper order and structure for storing information. Now imagine how it would be possible to manage this amount of information without databases ?!

Database-related terms and concepts

The database consists of various components and sections responsible for organizing information together. Each of these components and sections has different tasks and letters. Knowledge of each of these sections is essential for those who want to design a database. Among the most important terms in the field of database design are the following:

Common problems in database design

Designing and creating a database for different software requires expertise, experience, and knowledge of how different DBMSs work. Different people play a role in designing, building, and managing a database. Each has different responsibilities, including Database Designer, Database Administrator, and Database Programmer. Usually, the biggest problems arise in the design phase of databases. The most common problems in database design are:

Conclusion

At any given moment in our world, huge amounts of information and data are generatable and then exchanged between different systems. This information and data have a very important place in the age of communication and technology. All programmers need to know what a database is and how they can use it to create applications. Imagine that all this information is stored in a place without any security and rules without any order.

Then we want to access all of this data or part of it to process and process. It would certainly be impossible to do so without organizing this information. Therefore, using a database to store and organize information is essential. To this end, new database management systems have been developed to meet our need to store large volumes of information.
