Explain some points on database management systems in cloud computing? Cloud computing provides the services of implementing the database management system to process the data to the client user for a specific task to process it. The database management system included the different types of manipulations command that can be performed on the database file into the relational database file and object database file with different types of query language, where the relational database model uses the SQL and Object database model uses OQL on the database files to manipulate the database information. The user can use the processing of the database using the application program interface to apply the database command on the information to manipulate it depending on the user requirements. Database Management Systems (DBMS) in cloud computing offer scalable, flexible, and cost-effective solutions for storing and managing data over the internet. Unlike traditional on-premise databases, cloud-ba...
What are the three levels of architecture in Database management system?
There are three levels of architecture in DBMS. Database Management
system divided into three types of categories. The three levels of architecture
are uses to better understanding with their different levels in the DBMS models.
These three levels are explained in a short description.
The three levels are categorized of DBMS model following below.
- External level
- Conceptual Level
- Internal level
External Level
- This is the level is also known as View level.
- This level interacts with users directly.
- It is the closest level to the users.
- Users can understand with this level about the DBMS model.
- It is also called Graphical interface level.
- In database, data are observed by the individuals.
- There are so many views in a view level category. Every viewer can observe only their own database about their information or personal information of the user.
How do you understand by View level in the DBMS?
- The external level can show of the user database interface from the database management system model.
- The user or client can understand their data or information from the whole database.
- Client view their only own information from the database of the system or organization.
- The viewer can control their own information or database from the system which the user or viewer has taken the permission from the system. Such as change their user identity name and password etc.
- Viewer have an authority to deactivate your identity from the system as system and their under of terms and conditions.
- The terms and conditions is also a part of view level or external level of the database for the client, user or viewer. These terms and conditions cannot be changed without the permission of the admin of the database management system of organization or system.
Conceptual level
- It is also known as logical view level of database.
- It describes the different types of data are stored in a database.
- The level of indication is to show their relationships between data.
- This concerned about what are the information stored in the database in any model of the database.
Internal level
- It is known as physical level of the database.
- You can stores the database in the storage devices.
- It is the level is very closest to the storage devices.
- You can stores the database in the devices such as Hard disk, SSD, Pen drive etc.
