What are the 4 types of databases?

The database is a collection of information and the information is a collection of data where the two data have a relation to each other and connected to each other makes information and so much information makes a particular database of an object or subject in the relational database model.

The database includes the records and attributes which is known as the record is a row and detail about the object and subject, and the attributes are used to describe the properties of the object and subject.

The database is used to provide the data processing system on the web application software, website and offline application software on the smartphone and computer system.

The database is a combination of records and their attributes that makes a complete the database file and processed by the query language and program that applied to process the data such as create a table is used to perform making database which is a blank or empty and it need to insert new data in their row in the relational database model not an object database model.

The database also perform a manipulation language or command on the data such as insert into table name(col_name,1,2,3…, column N) where id = “id number” which is used to find and target the id to feed the data into the record using the primary key declared in the database model of relational in the sql programming language.

Introduction to the topic of computer related and the topic is related to the computer database technology is following below here:

What are the 4 types of databases?

Let's discuss the topic related to computer database technology and the topic is "What are the 4 types of databases?" explanation following below here:

What are the 4 types of databases?

There are some points on the computer system and database technology related to the topic of "What are the 4 types of databases?" following below here:

• Relational database for processing the text data only

• Object database processed by the object oriented programming

• Object and relational database model for combination of both types of object based data and relational database

• Security database model for every type website and web application and application software development for their security purpose 

Let's discuss the points listed above about the computer system and database technology related to the topic of "What are the 4 types of databases?" explanation following below here:

Relational database for processing the text data only

Relational database for processing the text data only that means the text data is only processed in the relational database not an object based data. The object based data cannot be processed because the relational database is made for only processing the text data to store the data in the 2 dimensional structure database model such as matrix form of data or you can say the 2 D array structure or table form of database.

The relational database program processes the object based data such as image database, audio database and video database because these are the types of file that are processed by the object oriented database programming.

The relational database model processes some basically three types of commands such as data definition language, data manipulation language and data control language from the sql programming on the relational database model for website, web application and offline application software database processing.

The relational database model is made up of rows and columns that are described as rows are records or tuples and columns are described as attributes or properties or characteristics etc.

The primary key and other types of keys are the attributes which are used to define the record that is unique from all the types of records of any types of object and subject data stored in the relational database model file.

Object database processed by the object oriented programming

Object database processed by the object oriented database programming which is describes only the object base data inside the file such as image data shows the coordinates of an object in the 2 dimensional structure in a computer graphics, similarly video data is a combination of image as frame rate per second running in the timeline and the audio database stores the data of frequency in the particular patterns and stores in the particular file which is used to considered as a object based patterns stored in the audio file.

The video file also contains the object in the motion according to their timeline processing the frame rate of images moving in a sequence per second.

The object based file is processed by the object oriented database programming which also describes the data such as class of an object, object define, attributes of an object etc. the object is a main part of object database which is categorized by the classes and shows their properties on the attributes.

For example:- a car is an object and their class is “C” model and attribute is “petrol variant” or “diesel variant” and multi-jet engine etc. these are the properties of a car in the object database model stored in the model of object database.

Object and relational database model for combination of both types of object based data and relational database

Object and relational database model for combination of both types of databases which is used to process all the types of data such as text, image, audio and video database file.

The object name with attributes are stores in the record on the relational database model known as a class and the attributes are the same and describe the same data stored in the columns on both sides of the database where the attributes are the properties of an object in the relational database model stores through the ORM mapping language.

The schema of both type of database is used to connect to each other through the ORM which is used to convert the database to each other that means the ORM is used to map the object database model is used to convert into the relational database model and relational to object database model on the ORDBMS ( Object - Relational Database Management System).

Security database model for every type website and web application and application software development for their security purpose

Security database model for every type of websites, web application and offline application software to process the data as a backend processing system to process the data for providing the data after processing by the database programing system.

The security database is processed by the control language of data that means the data control language is a DCL of sql structured query language for data processing system website, web app, and offline application software.

The database control language such as grant, revoke and deny which is used to control the data stored in the database of security.

The security database as a name of database file such as “security.db” is a typical file name with extension on the memory saves in the computer system.

The security database file is used to process the data using these types of commands that process the data and controlled by the database programming.

The application software is used to interact with the design interface of the security form or layer to secure the user database on the application software protected by the data control command language programs working behind the interface of the security layer on the application software or web application or website.

The DCL work as if the user verify the user name and password then the grant is used to hold the process of accessing the account of user and cannot granted the permission to access the user account on the application software when the user type the right username and password detail these data is matched from the user record from the particular database file and then verify the user account to access the permission on the web application, website and offline application software.
