Database Management Systems

This determines how the various objects are represented for exchanging them between different OODBMS.

Homogeneous database simplifies the data sharing between different users.

Serialisability is the main criterion for the accuracy of simultaneous transaction executions and a main objective for concurrency control.

The correct JDBC sequence is: 1) Register Driver, 2) Get Connection, 3) Create Statement, 4) Execute Query. First, you register the JDBC driver, then establish a connection to the database, create a statement object, and finally execute the SQL query.

Information is processed data that provides context and meaning, which is essential for making informed decisions in organizations and daily life.

In this specification of data structure, the user is modeling real life data in a specific context.

This is an advantage of the hierarchical data model as it is based on inbuilt structure of parent and child relationship.

The machine which is utilised for running user interface is considered as database client.

This criterion is most extensively accepted for the classification of a database.

It can read, but cannot perform updation of local data items.

Integrated Management System is a concept that offers the information needed to handle organisations in an efficient and effective manner.

Deferred-write and deferred-update are used by the recovery process when the transaction operations do not update the physical database instantly.

Personal database is prepared for assisting one client and offers him some quality of data proficiency.

On the failing of a transaction, the system is required to return to the situation that it was in before the transaction was initiated. It is called as cascading rollback.

In this approach, the client processors of OODBMS have an interaction with a network file service for reading and writing database pages.
