What are the 5 important objects of the database?

The database is used to describe the data and its relation with the applied rule or protocol followed by the query program on the data to define the database and manipulation of data. The data can be controlled by the query command programs that provide the security system for the user on the particular application software or website or web application software.

The database is processed by the query program which is used to basically apply the data definition language, data manipulation language and data control language.

The data definition language is used to define the database and removes the database file from the memory device of the computer system.

The data manipulation language is used to edit the data which has been saved in the database file. Similarly, the update the data, display the data, insert the new data etc. These are the types of operations applied on the database file and also on the data in the database file.

What are the 5 important objects of the database?

There are some points on the computer system and object database model related to the topic of "What are the 5 important objects of the database?" following below here:

In the relational database model have have 5 important objects are:-

• The tuple is a row in the tabular form of database model

• Attributes is a property of a record in a database model

• Key attributes is uniquely identifies the records 

• Query process for data on the database model

• Protocol of database for creating, manipulating and control data 

In the object database model have 5 important objects are:-

• Object in the object database model

• Classes are used to categorized the data of object

• Attributes is used to describes the data of object in the form of properties

• Query process is used to process the data of object

• Its protocol to apply the definition, manipulation of object data

Let's discuss the points above about the computer system and the database technology related to the topic of "What are the 5 important objects of the database?" explanation following below here:

In the relational database model have have 5 important objects are:-

The tuple is a row in the tabular form of database model

The tuple is a row in the tabular form of database model that means the tuple is a row that stores the data according to the attributes one by one in a particular cell. The cells are made from the attributes and records intersect to each other and the cells space is designed in the tabular type of database model.

The tuple stores the data according to attributes or it can be the data is an attribute data because the name of the record is also an attribute of the record to describe the properties as a name of the object or subject.

Record is a definition of particular data about the object or subject that means only the unique object or subject details can be stored in the record which describes the attributes of the records in the database model. The same attributes of records cannot be described; both are different data in the record.

Attributes is a property of a record in a database model

Attributes is a property of a record in a database model that means attributes are the data of records that provides the information about the record and the record can be an object or subject related to stores in the particular tuple or row or records horizontally.

The attributes are stored vertically on the relational database model which describes the properties of the subject or object depending on the type of data.

The attributes can be unique to identify the record which is used to find easily from the relational database file.

Attributes are used to describe the description which contains the information about the object or subject in a sentence or in some words. The other types of attributes are generally stored the data in one word in a cell of the record.

Key attributes is uniquely identifies the records

Key attributes is uniquely identifies the records when the user find the particular record of the object or subject then they need to apply the key attributes on the database on the query program to find the particular records such as the key attributes can be a registration number and the registration number is used to find the record easily from the relational database model.

The key attributes can be primary key, foreign key, candidate key, composite key, super key, secondary key, alternate key etc.

These are the keys that also define the different types of database according to the keys attributes.

The key attribute is used to define the unique data stores in the attributes or columns or fields of the relational database model.

Query process for data on the database model

Query process for data on the database model is used to provide the data processing using program structure query language performed on the relational database model file.

The query process to find the data, create a new table or database, to define the name of the database file which saves in the memory of the computer system.

The query can process the data in the application software as a backend processing system for the user to get the output data processed by the query program on the database and provide to the end user on the output panel in the design interface of the application software or website or web application software etc.

Protocol of database for creating, manipulating and control data

Protocol of database is a rule that applies on the data to save, create, edit and control the data using the different types of commands on the database.

The rule of databases is to manage the data and make a system in the database model of relational which is known as a relational database management system.

The relational database management system applies some query commands such as DDL, DML, DCL etc. These are the basic query commands that performs in the database file and also programmed for processing the data using these commands to perform the operation of data processing such as:- DDL is a Data Definition Language contains commands create, alter and drop which is used to apply on the database file which is used to define the database file and removed from the memory device of the computer system, The DML is a Data Manipulation Language contains some commands such as update, delete, insert etc. And the DCL is a Data Control Language containing commands grant, revoke and deny which is used to control the data for security systems and verification of record using the control commands on the relational database model and also performed in the web application, offline application, website and operating system or system software.

In the object database model have 5 important objects are:-

Object in the object database model

Objects in the object database model are real life which have their own properties that describe them in the object database model.

Object database stores only the object related data in the object database file.

The database files such as image file, audio file and video file etc. Which contains object data displays according to the coordinates of the object in the pixel resolution of the computer graphics program. The audio data is stored in the frequency patterns of sound coming from the microphone input device and stored in the frequency patterns in the audio file which is considered as an object database.

The object database is used to describe the object with their properties known as attributes.

Classes are used to categorized the data of object

Classes are used to categorized the data of object that means the classes is used as category or structure of object to define the record in the relational database model and object database model describes the class as a record and class has their attributes which describes the properties of object example.

The object is an example in the object database model which stores in a class as structure and their properties defined by the attributes of an object.

The class of an object describes the structure such as an object is a product of an electronic device or smartphone. The class of smartphone is a "model name" of the smartphone category and their attributes are touch screen, expandable memory, insert memory card, 5 generation network or 5g etc. These are the properties of the Smartphones.

Attributes is used to describes the data of object in the form of properties

The attribute is used to describe the data of an object in the form of properties that means the property is a description in one word or in a sentence to explain the detail about the object in the object database model.

The class has attributes of an object example which describes the details of the object and provides the information about the object.

The attributes can be unique attributes for objects which define the object as unique or different from the other object data.

If the brick object has a company name as a class and the attribute is height of brick is 3.2 inches of height is an attribute but the unique object bricks has maximum height is 4.5 inches which is bigger than the other bricks object stored in the object database model.

Query process is used to process the data of object

Query process is an OQL that means the Object Query Language is used to describe the object details and define the object depending on their classes and its attributes of the object.

The object example has so many attributes that means the object can be a complex model which is difficult to described in the relational database model and the object database model can easily describes the object attributes with their classes of objects example.and classes in the minor difference also can be described in the attributes of an object in the object database query language or OQL.

Where the ODL is used to define the object and construct the classes and interface of the object in the object database model but the OQL is used to manipulate the data in the object database model.

Its protocol to apply the definition, manipulation of object data

The object database is defined by the ODL is used to create a construct of classes and interfaces and OQL is used to manipulation the data in the object database model to perform some operations such as select from clause is syntax of the Object query language that is used to find and retrieve the data using the clauses to apply such as where “Id = 1” of an object saved in the database.

The limit can also be a component OQL to sorting the data from the object attributes lists from the object database model.

The object database protocol is applied on the data of objects and attributes used with the FROM clause to designate the attribute data stored in the object database model.
