What problems do Database Management Systems solve?

The problems of the database file in the database management system software for processing the database file to process the data and create a new data on the Relational database model file to store the new data into the new relational database file in the memory device of the computer system or smartphone device.

The relational database model stores the data according to the record and the record defines more information through the different types of categories of attributes or properties that defines the records new information about the object details or subject details on the relational database model file of the computer system.

The database model process attributes values on the record in the relational database model using the query processor that applies the operation on the record with the help of key attributes that are applied on every type of record on the relational database file. The query language is three types to process the data in the relational database model such as:- the data definition language, the data manipulation language and the data control language of the SQL means Structure Query Language. These types of languages apply the operations on the particular database file and table according to the name of the table. The table included records and attributes with key attributes are also mentioned in the table to trigger the operation of the command from the query language on the table or database file.

What problems do Database Management Systems solve?

There are some points on the computer system and database technology related to the topic of "What problems do Database Management Systems solve?" following below here:

• Database file included for data processing using the Query language

• Database file provides the manipulation of data and edit data for user

• Database file process the object level of data using the query language

• Database system used for security system to control data on software systems

Let's discuss the points above about computer systems and database technology related to the topic of "What problems do Database Management Systems solve?" explanation following below here:

Database file included for data processing using the Query language

Database file included for data processing using the query language that means the query language is a program and commands that applied on the database file of the relational database model to process the data using the logical level of operations on the record and attributes of the record to manage and insert new data into the record if the new data and information need to be included into the database file of the relational database model.

The relational database model only uses a query language for SQL to process the data according to the records and attributes with the target applied through the key attributes on the record which is used to apply the command on the record and operations on the relational database model file.

The query is a program that process the records values on the relational database model file and the query command applies the operations on the record through the key attribute such as:- primary key is a key attribute that mostly and commonly used on the relational database file for every table structure on the records that provide to target the record or row in the table and apply the operations on the record and the operations can performs on the attributes of the records. If the user wants to find a minimum mark from the particular subject such as English then it will show the marks with the reference of the primary key on the sql data manipulation language on the database file on the particular table.

Database file provides the manipulation of data and edit data for user

Database file provides the manipulation of data and edit data for user that means the manipulation command is used to apply on the database file to provide the management of the data in the record of the attributes and provide the data consistency also which is managed by the manipulation command of the SQL program to apply on the record of the relational database file 

The manipulation command such as:- insert which is used to fill up the new data in the record with the mentioned columns as attributes of the records, delete command is used to remove the record information with all values of attributes in the relational database file, update is used to change the existing record values according to the attributes and records.

The data manipulation language is used for editing  the database file of the records values changes from the command of update basically applies on the particular record to change the data of the attribute or value of the attribute on the relational database file provide the updated new information for the end user on the database file when the user want to see the records values on the relational database file.

The data manipulation language also deletes the whole records using the delete command on the relational database model. The database file is used to apply on the record and the operations of data manipulation command applied on the record using the key attribute and the key attributes such as:- 1099, 1100, 1101 etc. as a primary key to identify the record easily from the table on the relational database file.

Database file process the object level of data using the query language

Database file processes the object level of data using the query language on the object database model file depending on the object based files such as:- an image data is used to show the object with the coordinates defined in the image according to the computer graphics on the image in the unit of pixel resolution.

The audio data is recorded the frequency data on the file and the patterns of frequency is measured in the graphs to define the different types of frequency to play the audio data from the speaker output device, video data is object in motion in the particular environment of the object to moves according to the timeline and the unit of frame rate per second.

The object based file is used to provide the object data and information depends on the type of file of the object database such as:- image database is used to shows the object in the graphs of object with the coordinates mentioned in the object to identify the properties using the measurement of object according to the graphs and other information also provided by the image file in the form of text entered into the image and other environment on the image background in the image file. The audio database file is used to record the frequency patterns in the waves in the digital form of data record in the audio data file and provide the audio player to read the frequency patterns recorded from the audio database file and provide the sound which is processed by the object query language to process the frequency patterns recorded on the file of audio. The video database included all types of data in the particular file according to the timeline of the video database. The video file is used show the frame per second of the data in the graphs and object in motion to provide the full of information of the object in the video data processed by the object database language that work when the application is used to work on the object based file such as:- image, audio and video file.

Database system used for security system to control data on software systems

Database system used for security systems to control data on the software system or application software to provide the security layer on the design interface also to show the layer of connecting the account accessing from. The security interface is connected to the account accessing form interface to verify the user identity which the user created that system to verify the input values when the user wants to access the account before verification of username and password on the software systems or application software.

The username and password is controlled by the data control language to provide the verification system on the security model to the user to protect the unknown users on the account accessing the software systems or application software or website interface of security or operating system account security or web application also.

The DCL from SQL is a main language that applies programs on the security model to provide the data controlling system on the database file and it is provided the verification process of the user through the two types of attributes are username and password. The username and password is basically the attributes values for the record of the user, the record in the relational database model file stores the values of username and password on the database file and their records of users are accessed by the key attributes of the particular database file. The username and password are the verification values that are controlled by the data control language from the SQL programs on the security model used for any software systems such as:- website, application software, web application etc. On the computer system or smartphone device.

The other increased security feature options that included after verification of the username and password such as:- secret code, OTP code verification, email code verification, security interface verification included yes or no option on the mobile device etc.

The secret code is generated by the end user to verify after username and password, similarly the OTP code is sent to the mobile device of the user to take an action manually to check it and enter the correct code into the OTP form or email verification is also a same method based verification system. But the security interface page verification is sent to the user's contact of smartphone device to take an action over the form which has been sent to their number through the server network device included the form options are 'yes' to agree to access the account or 'no' for cancellation of the security procedure on the software systems on the computer system or smartphone device.

These are very useful interfaces of the security model to provide the increased level of user data protection on their user account on the software systems such as:- website, application software web application etc.

The object verification process for the user is important because the object database verification system is based on the object based files such as:- image data, audio data and video data. That means the image data is verified in the form of still object verification in the form of face verification. Similarly, the video data verification is similar to the image but there is a difference if the user moves their faces on the camera input device and verifies their face to unlock the user account. The audio data is used in the form of the user voice verification process to verify the user voice matches with the same frequency from the audio database of the security model on the object based high level verification process. It is used for privilege to access their sensitive database after being accessed by the user account on the software systems or application software on the computer system or smartphone device.
