    The main difference between a database system and a file system is the way in which data is organized, the file system is oriented to the organization of data, while the database system is oriented to the global organization of data, which can solve the problem of data redundancy.

    The database system mainly manages the storage, transactions, and operations on the database. A file system is a subsystem of the operating system that manages files and storage space, mainly allocating clusters, disks, creating FAT, and managing space occupied by files.

    Generally speaking, database systems will call the file system to manage their own data files, but there are also database systems that can manage their own data files, even on bare devices. The file system is required for the operating system, while the database system is only necessary for database management and applications.

    Features of the database system:

    1. The structure of data, good data sharing, good data independence, small data storage granularity, and data management system provide users with a friendly interface.

    2. The core and foundation of the database system is the data model, and the existing database system is based on a certain data model.

    3. The core of the database system is the database management system.

    4. The database system is generally composed of a database, a database management system (DBMS), an application system, a database administrator and a user. DBMS is the foundation and core of a database system.

    1. Data structuring. The database system realizes the structure of the overall data, which is one of the main characteristics of the database, and it is also the essential difference between the database system and the file system.

    2. The database system has high data sharing, low redundancy and easy expansion.

    3. The database system has high data independence.

    4. The data in the database system is managed and controlled by DBMS.

    Database systemsThe main difference with the file system is that the file system cannot be solvedData redundancyand data independence issues, while database systems can.

    A database system DBS typically consists of software, databases, and data administrators. Its software mainly includes operating systems, various host languages, utilities, and database management systems.

    The database is managed by the database management system, and the insertion, modification and retrieval of data are all carried out through the database management system.

    The main purpose of database technology is to effectively manage and access a large number of data resources, including: improving data sharing, reducing data redundancy, and providing data and applications.

    independence. A file system is a logical storage and recovery system for naming files and placing them. A file system is an operating system that is used to explicitly store devices (most commonly, disks, but also NAND Flash-based SSDs).

    or the method and data structure of the files on the partition.

    That is, the method of organizing files on a storage device. The software organization responsible for managing and storing file information in an operating system is called a file management system, or file system for short.

    File system composition.

    The file system consists of three parts: the interface of the file system, the collection of software for manipulating and managing objects, and the objects and properties. From a system point of view, a file system is a system that organizes and allocates space for file storage devices, is responsible for file storage, and protects and retrieves stored files.

    Specifically, it is responsible for creating files for users, saving, reading, modifying, dumping files, controlling access to files, revoking files when users are no longer using them, etc.

    Difference between file system and database system.

    1) The file system uses files to store data in external memory for a long time, and the database system uses databases to store data in a unified manner;

    2) There is a certain relationship between the program and the data in the file system, and the program and the data in the database system are separated;

    3) The file system uses the access method in the operating system to manage the data, and the database system uses the DBMS to manage and control the data in a unified manner;

    4) The file system realizes data sharing in the unit of files, and the database system realizes the data sharing in the unit of records and fields.

    The link between the file system and the database system:

    1) are all management techniques of data organization;

    2) The data is managed by the data management software, and the access method is used to convert the program and the data;

    3) The database system is developed on the basis of the file system.

    Answer]: In the file system, the simplest form of the internal structure of independent records is a collection of records of equal length and the same Tong chain brother format, which is easy to cause a large waste of storage space and is inconvenient to use. Whereas, in a database system, data is the structure.

    This structuring requires that the data be described not only by describing the data itself, but also by describing the relationships between the data, which is achieved by employing a specific data model. For example, the answer to this question is c.

    1. The difference between a file system and a database system

    The file system is oriented to a certain application, with poor sharing, large redundancy, poor data independence, and the record has a structure and no structure as a whole, and is controlled by the application itself.

    The database system is oriented to the real world, has high sharing, small redundancy, high physical independence and certain logical independence, is overall structured, and is described by a data model, and the database system provides data security, integrity, concurrency control and resilience.

    2. The connection between the file system and the database system

    File system and database system are both software that manages databases in computer systems. Parsing a file system is an important part of an operating system.

    Whereas, database system DBMS is software that is independent of the operating system. At that time, the DBMS Lion Ah operating system was implemented on the basis of the implementation. The organization and storage of the database system is achieved through the file system in the operating system.

The deletion operation in the data is irreparable, sometimes the data in the data table may be deleted due to misoperation, or the database crashes for other reasons, and all the data is lost, especially when there is a large amount of useful data in the database, then it is impossible for you to enter the data again from the beginning, this is the role of the backup database, back up the database, when the above situation occurs, you can restore the previous database through the backup file.
