If today data and information are considered to be like a great treasure, databases can also be thought of as vaults in which these treasures are stored. In many areas, from social media to government offices, desktop software to mobile apps and personal websites, data is the greatest strength. A person adds or updates various information to these databases at any time, even if they are not aware of it, both in the Internet world and in everyday life. “What is a database?” Continue reading the article for details on how database management systems work.
A database is a structure in which a lot of data is stored and organized. Databases are software used to store, query, modify, and delete data. Databases offer a variety of management tools to facilitate the security and use of data. For example, the database manager can be used to store, query, backup, and restore data.
Databases ensure that data is stored and managed in a secure, fast and easily accessible way. This is important for more effective use of data and to increase efficiency. Furthermore, databases ensure that data is kept current, accurate, and complete, regardless of the size, scope, and complexity of the data. Databases can also be used to query, report, and analyze data, which provides important information in the decision-making process.
Databases facilitate the process of sharing and updating data, especially for large or multiple users. For example, all departments of a company can access and update data from the same database, increasing the accuracy and timeliness of this data. Databases can also be used to protect and back up data. For example, the data database administrator can continuously back up data and restore those backups, which increases the security of the data and can be used to restore data in case of loss of data.
Finally, databases are important for artificial intelligence and analytical applications such as data mining and machine learning. These applications use databases to collect, store and analyse data from multiple sources.
Database systems consist of a set of components that are mainly used to store, query, modify, and delete data. These components include:
Data files: This is where data is physically stored. The data is stored on disk and managed by the database administrator.
Data structures: Defines how data is stored and accessed. For example, the relational data model stores data as tables and uses SQL to query it. The document data model stores data as documents and uses NoSQL to query it.
Database manager: Enables the operation of the database system and the management of data. The database manager is used to store, query, backup, and restore data.
Data layer: It is the interface used to access the database. This is the API used to access the database on the axis of applications and users.
Security components: They are components that are used to ensure the security of the database. For example, such as user authentication, encryption, and data access controls.
Backup and restore components: They are components used to back up and restore the database. These components include backup management, restore management, data recovery, and data protection.
Data management and optimization components: They are components used to optimize the data management and performance of the database. These components include indexing, lock management, consolidation, and data storage.
Database management system (DBMS) is software in which data is stored and managed in a secure, fast and easily accessible way. A database management system includes interfaces, tools, and technologies used to store, query, modify, and delete data. A DBMS meets the requirements of users and applications to manage and use the data, regardless of where the data is physically stored.
The database management system includes interfaces, tools, and technologies used to store, query, modify, and delete data. Among these interfaces, SQL (Structured Query Language) is the most widely used. SQL is used to query, add, update, and delete data within the database. Furthermore, the database management system manages data regardless of where the database is physically stored. This means that it does not matter how the database is physically stored (for example, hard disk, virtual machine, cloud, etc.).
Database management systems use a variety of mechanisms to ensure the security and performance of data when managing data. For example, the database management system uses authentication and authorization mechanisms to control user access. At the same time, the database management system uses backup and restore mechanisms for backing up and restoring data.
The database management system uses various optimisation techniques to optimise the performance of the database. For example, the database management system uses indexing to query the data. In this way, the database management system quickly searches and queries the data. In addition, the database management system can also use methods such as parallel processing, data replication to query data. DBMS also allows the use of data for artificial intelligence and analytical applications such as data mining, Business intelligence and Machine Learning.
Database management systems (DBMS) are used in many different areas. In particular, DBMS ensures that data is kept current, accurate and complete, regardless of the size, scope and complexity of the data. Therefore, DBMS is used in a very wide range of fields. Examples of these areas include:
· Businesses
DBMS is used for data storage and management in various enterprises. For example, departments such as accounting, marketing, sales and customer service use the database.
· E-Commerce sectors
E-commerce sites use the database to store information of products, stock status, orders and customer information.
· Financial sector
In the financial sector, it is used to store data such as databases, client accounts, portfolios, liabilities and investments.
· Health
Hospitals and healthcare organizations need databases to store data such as patient data, treatment information, and costs.
· Private service sector
Private services use databases to store data such as user information, memberships, services, and payments.
· Education
Educational institutions take advantage of this information store to store data such as student data, lesson schedules, grades, and teacher information.
· Government
Governments need to effectively manage databases to store data such as citizen information, tax information, security data, and records.
· Industry
Industry sectors want to best manage their databases to store data such as production data, supply chain data, and product information.
· Science and research
Science and research institutions use databases to collect, analyze, and report data. For example, it makes use of databases at any time for the collection and storage of data in genetic, meteorological, seismic and large areas.
· Media and entertainment
The media and entertainment industries use databases to store and manage content such as programs, movies, music, and games.
· Logistics and transportation
The logistics and transportation sectors receive support from databases to analyze data such as material management, shipping information, and shipment data.

It is difficult to make a clear definition of data quality. The truth is that your data quality is good if the data achieves its purpose of using it. For example, showing the right values on a management board to guide the organization ensures that management is also consistent and the process is managed correctly.
