You may be wondering what it is. With the introduction of this concept in the field of applications, a revolution is underway in their development. Almost today, it will be very difficult to find applications that do not use it. If you want to know more about it and its applications, we invite you to continue this article.<\/span><\/span><\/p>\n<h2><span class=\"VIiyi\" lang=\"en\"><span class=\"JLqJ4b\" data-language-for-alternatives=\"en\" data-language-to-translate-into=\"fa\" data-phrase-index=\"0\">What is a database?<\/span><\/span><\/h2>\n<p><span class=\"VIiyi\" lang=\"en\"><span class=\"JLqJ4b\" data-language-for-alternatives=\"en\" data-language-to-translate-into=\"fa\" data-phrase-index=\"0\">A database is a collection of organized information that is organized according to 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. According to this definition, a phone book or a list of goods in a store&#8217;s warehouse is also a kind of database.<\/span><\/span><\/p>\n<p><span class=\"VIiyi\" lang=\"en\"><span class=\"JLqJ4b\" data-language-for-alternatives=\"en\" data-language-to-translate-into=\"fa\" data-phrase-index=\"0\">In computer science, a database is a place where information about software, websites, etc., is stored. It makes it much easier to access and manage stored information based on the rules it uses to organize information. Using it 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. Also, using it gives us other benefits such as information independence, eliminating duplicate processes, increasing security, the possibility of backing up data, and so on.<\/span><\/span><\/p>\n<h3><span class=\"VIiyi\" lang=\"en\"><span class=\"JLqJ4b\" data-language-for-alternatives=\"en\" data-language-to-translate-into=\"fa\" data-phrase-index=\"0\">A simple example of a database<\/span><\/span><\/h3>\n<p><span class=\"VIiyi\" lang=\"en\"><span class=\"JLqJ4b\" data-language-for-alternatives=\"en\" data-language-to-translate-into=\"fa\" data-phrase-index=\"0\">Now that we know what a database is, we are going to look at a simple example of one. Imagine you are going to rent a house in one of the areas of New York. To do this traditionally, you should consult a real estate consultant in that area. A 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&#8217;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.<\/span><\/span><\/p>\n<h3><span class=\"VIiyi\" lang=\"en\"><span class=\"JLqJ4b\" data-language-for-alternatives=\"en\" data-language-to-translate-into=\"fa\" data-phrase-index=\"0\">Databases in the computer world<\/span><\/span><\/h3>\n<p><span class=\"VIiyi\" lang=\"en\"><span class=\"JLqJ4b\" data-language-for-alternatives=\"en\" data-language-to-translate-into=\"fa\" data-phrase-index=\"0\">One of the most common uses of a database is to manage information in <a href=\"https:\/\/ded9.com\/14-best-free-remote-access-software-tools\/\">software<\/a>. In this section, we will mention an example of the use of databases in software.<br \/>\n<\/span><\/span><\/p>\n<ul>\n<li><span class=\"VIiyi\" lang=\"en\"><span class=\"JLqJ4b\" data-language-for-alternatives=\"en\" data-language-to-translate-into=\"fa\" data-phrase-index=\"0\">The site contains a table of information about registered users in its database.<\/span><\/span><\/li>\n<li><span class=\"VIiyi\" lang=\"en\"><span class=\"JLqJ4b\" data-language-for-alternatives=\"en\" data-language-to-translate-into=\"fa\" data-phrase-index=\"0\">All articles and posts on the site are in a separate table.<\/span><\/span><\/li>\n<li><span class=\"VIiyi\" lang=\"en\"><span class=\"JLqJ4b\" data-language-for-alternatives=\"en\" data-language-to-translate-into=\"fa\" data-phrase-index=\"0\">In anot<\/span><\/span><span class=\"VIiyi\" lang=\"en\"><span class=\"JLqJ4b\" data-language-for-alternatives=\"en\" data-language-to-translate-into=\"fa\" data-phrase-index=\"0\">her table, educational videos and video files are stored.<\/span><\/span><\/li>\n<\/ul>\n<p><span class=\"VIiyi\" lang=\"en\"><span class=\"JLqJ4b\" data-language-for-alternatives=\"en\" data-language-to-translate-into=\"fa\" data-phrase-index=\"0\">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, forms the database of the site. 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 if there were no databases ?!<\/span><\/span><\/p>\n<h3><span class=\"VIiyi\" lang=\"en\"><span class=\"JLqJ4b\" data-language-for-alternatives=\"en\" data-language-to-translate-into=\"fa\" data-phrase-index=\"0\">Database-related terms and concepts<\/span><\/span><\/h3>\n<p><span class=\"VIiyi\" lang=\"en\"><span class=\"JLqJ4b\" data-language-for-alternatives=\"en\" data-language-to-translate-into=\"fa\" data-phrase-index=\"0\">The database consists of different components and sections that are responsible for organizing information together. Each of these components and sections has different tasks and letters. Understanding 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:<\/span><\/span><\/p>\n<ul>\n<li><span class=\"VIiyi\" lang=\"en\"><span class=\"JLqJ4b\" data-language-for-alternatives=\"en\" data-language-to-translate-into=\"fa\" data-phrase-index=\"0\"> Table: A database can have one or more tables. Each table in it is responsible for maintaining a group of information. Each table can have several columns and rows.<\/span><\/span><\/li>\n<li><span class=\"VIiyi\" lang=\"en\"><span class=\"JLqJ4b\" data-language-for-alternatives=\"en\" data-language-to-translate-into=\"fa\" data-phrase-index=\"0\"> Column or Attribute: Each table in a database can have multiple columns. Each column is responsible for maintaining a specific attribute or value of a variable. For example, name column, last name, etc.<\/span><\/span><\/li>\n<li><span class=\"VIiyi\" lang=\"en\"><span class=\"JLqJ4b\" data-language-for-alternatives=\"en\" data-language-to-translate-into=\"fa\" data-phrase-index=\"0\"> Row: Each row of the data table is called a record. Each record is a set of attributes that are considered in the columns of that table. For example, information about a user is a record in a user table.<\/span><\/span><\/li>\n<li><span class=\"VIiyi\" lang=\"en\"><span class=\"JLqJ4b\" data-language-for-alternatives=\"en\" data-language-to-translate-into=\"fa\" data-phrase-index=\"0\"> Type (<a href=\"https:\/\/www.domain.com\/\" target=\"_blank\" rel=\"noopener\">Domain<\/a>): Each column of properties has a specific format of data called Type. Data can be of different types, including string, integer, and so on.<\/span><\/span><\/li>\n<li><span class=\"VIiyi\" lang=\"en\"><span class=\"JLqJ4b\" data-language-for-alternatives=\"en\" data-language-to-translate-into=\"fa\" data-phrase-index=\"0\"> Entity: Existence is a general concept of what we intend to store its properties and information in the database. For example, an object, a human, a customer, etc., are examples of an entity in the database, each of which has its own characteristics.<\/span><\/span><\/li>\n<\/ul>\n<h3><span class=\"VIiyi\" lang=\"en\"><span class=\"JLqJ4b\" data-language-for-alternatives=\"en\" data-language-to-translate-into=\"fa\" data-phrase-index=\"0\">Common problems in database design<\/span><\/span><\/h3>\n<p><span class=\"VIiyi\" lang=\"en\"><span class=\"JLqJ4b\" data-language-for-alternatives=\"en\" data-language-to-translate-into=\"fa\" data-phrase-index=\"0\">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 it. Each has different responsibilities, including Designer, Administrator, and Programmer. Usually, the biggest problems arise in the design phase of it. The most common problems in database design are:<\/span><\/span><\/p>\n<ul>\n<li><span class=\"VIiyi\" lang=\"en\"><span class=\"JLqJ4b\" data-language-for-alternatives=\"en\" data-language-to-translate-into=\"fa\" data-phrase-index=\"0\"> Improper selection of the DBMS according to the intended purpose<\/span><\/span><\/li>\n<li><span class=\"VIiyi\" lang=\"en\"><span class=\"JLqJ4b\" data-language-for-alternatives=\"en\" data-language-to-translate-into=\"fa\" data-phrase-index=\"0\"> Improper database design<\/span><\/span><\/li>\n<li><span class=\"VIiyi\" lang=\"en\"><span class=\"JLqJ4b\" data-language-for-alternatives=\"en\" data-language-to-translate-into=\"fa\" data-phrase-index=\"0\"> Poor naming of tables<\/span><\/span><\/li>\n<li><span class=\"VIiyi\" lang=\"en\"><span class=\"JLqJ4b\" data-language-for-alternatives=\"en\" data-language-to-translate-into=\"fa\" data-phrase-index=\"0\"> Lack of documentation<\/span><\/span><\/li>\n<li><span class=\"VIiyi\" lang=\"en\"><span class=\"JLqJ4b\" data-language-for-alternatives=\"en\" data-language-to-translate-into=\"fa\" data-phrase-index=\"0\"> Do not test the database<\/span><\/span><\/li>\n<li><span class=\"VIiyi\" lang=\"en\"><span class=\"JLqJ4b\" data-language-for-alternatives=\"en\" data-language-to-translate-into=\"fa\" data-phrase-index=\"0\"> Lack of Primary<\/span><\/span><\/li>\n<\/ul>\n<h3><span class=\"VIiyi\" lang=\"en\"><span class=\"JLqJ4b\" data-language-for-alternatives=\"en\" data-language-to-translate-into=\"fa\" data-phrase-index=\"0\">key<\/span><\/span><\/h3>\n<ul>\n<li><span class=\"VIiyi\" lang=\"en\"><span class=\"JLqJ4b\" data-language-for-alternatives=\"en\" data-language-to-translate-into=\"fa\" data-phrase-index=\"0\"> Enter all information in a table<\/span><\/span><\/li>\n<li><span class=\"VIiyi\" lang=\"en\"><span class=\"JLqJ4b\" data-language-for-alternatives=\"en\" data-language-to-translate-into=\"fa\" data-phrase-index=\"0\"> Improper communication between different tables<\/span><\/span><\/li>\n<\/ul>\n<h3><span class=\"VIiyi\" lang=\"en\"><span class=\"JLqJ4b\" data-language-for-alternatives=\"en\" data-language-to-translate-into=\"fa\" data-phrase-index=\"0\">Conclusion<\/span><\/span><\/h3>\n<p><span class=\"VIiyi\" lang=\"en\"><span class=\"JLqJ4b\" data-language-for-alternatives=\"en\" data-language-to-translate-into=\"fa\" data-phrase-index=\"0\">At any given moment in our world, huge amounts of information and data are generated and then exchanged between different systems. This information and data have a very important place in the age of communication and technology. To do this, 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 rules or orders.<\/span><\/span><\/p>\n<p><span class=\"VIiyi\" lang=\"en\"><span class=\"JLqJ4b\" data-language-for-alternatives=\"en\" data-language-to-translate-into=\"fa\" data-phrase-index=\"0\">Then, we want to access all or part of this data to process and review. 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 amounts of information.<\/span><\/span><\/p>\n<h2>FAQ<\/h2>\n<div id=\"rank-math-rich-snippet-wrapper\"><div id=\"rank-math-faq\" class=\"rank-math-block\">\n<div class=\"rank-math-list \">\n<div id=\"faq-1\" class=\"rank-math-list-item\">\n<h3 class=\"rank-math-question \">What distinguishes a database from a simple file or spreadsheet?<\/h3>\n<div class=\"rank-math-answer \">\n\n<p>A database supports structured data storage across tables or collections, enforces constraints, supports concurrent access and complex queries through a DBMS\u2014unlike a basic file or spreadsheet which lacks these capabilities.<\/p>\n\n<\/div>\n<\/div>\n<div id=\"faq-2\" class=\"rank-math-list-item\">\n<h3 class=\"rank-math-question \">What are the core components and operations of a database system?<\/h3>\n<div class=\"rank-math-answer \">\n\n<p>Key components include the data itself (tables, documents), a DBMS that manages access, and applications that use it.
