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.

What do you mean by the "Mapping" of the database structure in DBMS?

What is “Mapping” in the DBMS?

Mapping in DBMS {Database Management System}

The mapping is a link or connect and equality to describe between view level, conceptual level and internal level.

It used to describe how they are connecting to each other in three levels.

It is a process to convert a request of external level which is request both the two level such as logical level and physical level.

Simply it is a map of Database structure which shows the links of the three levels basically.

There are two types of mapping in DBMS.

  • External conceptual mapping
  • Internal conceptual mapping
In the DBMS each users refers only its own external schema. Hence the DBMS must transform a request on a particular or specified external into the request against to the conceptual schema which means logical level of schema in the logical refers where the logical term has perform in the database and then into the request against internal schema which means the internal is schema in the physical level where the physical structure has their connectivity of the database to computer system or any hardware connectivity show in the physical level store and retrieve data to the database and from the database.
