What do you mean by database application on the computer? The database application provides the database tools to manage the data in the model of relational database. The relational database model application includes the different types of option and applies some query processes on the record of the database file and their attributes values in the table database. The query is performed by the query processor on the record using the key attributes on the relational database model. Database application included the different types of parts that process the data into the database file, where the user mostly uses the relational database model to process the text data in the table format of database file which included the record, attributes and query processor to apply the commands on the record to process the values of the attributes on the records of the relational database file. The user get the solution of the output data using the database programming to get the values processed by t

What is the functionality of the recovery manager in DBMS ?

There are some points on the computer system and database related topic of "What is the functionality of the recovery manager in DBMS?" following below here:


The functionality of the recovery manager in DBMS points are mentioned in figure and explained below the figure, such as manages data and info, work also on network fb, to make a backup db etc. What is the functionality of the recovery manager in DBMS ?
The functionality of the recovery manager in DBMS points are mentioned in figure and explained below the figure, such as manages data and info, work also on network fb, to make a backup db etc.

  • The database recovery manager is a term on the application software of database management system and recovery section
  • Recovery manager manages the data and information of files that contains valuable data for user
  • Recovery manager also works on the DBMS connected with network system
  • Recovery manager work on the additional storage to make a backup for saving the important database


Let's discuss the points above about the computer system and database related topic of "What is the functionality of the recovery manager in DBMS ?" explanation following below here:


The database recovery manager is a term on the application software of database management system and recovery section

The database recovery manager is a term on the application software of database management system and recovery section that means the recovery section is used when the user wants to save the database into the memory of the computer system which is a storage device known as permanent memory.

The computer system storage devices crash for some reason. 

Such as power cut off if the computer system is directly connected to the power supply without any UPS support.

Another reason is when the user directly closes the computer system in some case of hanging the operating system due to viruses or malicious files or may be deadlock conditioned through the button of the cpu cabinet or UPS power off button.

These are generally two big reasons or common reasons that make the system crash or storage device crash.

In that case the user needs to make a backup of the database on the particular additional storage device to retrieve the old database when the system crashes or the storage device crashes.

Another reason for system crashes is application software misbehaving on the device or computer system blocks and hangs activities on the computer system.

So, the database software makes backup on the storage device to install after if the system crashes. 


Recovery manager manages the data and information of files that contains valuable data for user

Recovery manager manages the data and information of files that contain valuable data for the user. That means the files which contain the information for the user are necessary to be recovered from the storage device if these files have been deleted by some reasons such as virus attack, format system due to malicious files, pirated application attacks etc. These are common reasons to remove the valuable file to protect from the corruption of the file into the storage device of the computer system.

The manager of the recovery section manages the files according to the user requirements, choosing these files which contain valuable content for the user's profits.

When the user needs to recover files from the memory of a storage device after using the protection of the antivirus application software.


Recovery manager also works on the DBMS connected with network system

Recovery manager also works on the DBMS connected with a network system that means the network system needs to connect with the database which is a combination of server to access the network system and memory storage device to store the data and information of the website and user as personal information.

Sometimes the database is damaged due to physical reasons or other programmatic reasons in the computer system and the database is lost due to the storage memory crash which is connected to the computer network system.

The recovery manager recovers the database from the storage device or additional backup recovery of the old database which has been deleted or removed from the database that connected to the computer network system.


Recovery manager work on the additional storage to make a backup for saving the important database

Recovery manager work on the additional storage to make a backup for saving the important database that means the recovery manager stores the backup database which has selected from the storage device of the computer system when the user needs to stores the backup of valuable files into the particular permanent storage device which has connected to the USB port of the computer system. 

The recovery manager works on the storage device which has connected to the computer system such as an additional storage device to make a backup to recover the database from the additional storage device. This is necessary when the user needs to format all the computer systems to remove malicious files or virus attacks on the storage device of the computer system to prevent the system crash and storage crash due to the reason of virus or malicious files.

After formatting the data from the storage device of the computer system the backup database from the additional storage device can recover the old database that has been removed from the computer system.

What are the three main purpose of an operating system? There are three main purpose of an operating system. 1. The first main purpose is User interface between hardware and users. 2. The second main purpose is to operate the internal parts of the computer properly and systematically using binary code system in the form of 0 and 1. 3. The third main purpose is to provide an environment for development of an application software and program to uses the hardware resources of the computer and connected to the computer parts which provides output to the user, the output from application software is very useful for users. Interface between user and hardware device  The operating system uses all types of interface such as command line interface, batch command interface and Graphical User Interface to interact with users to hardware peripheral devices through the monitor screen.
