Database Management Systems

Real-time processing means data is updated immediately as transactions occur, keeping files current with the latest transaction data. This contrasts with batch processing, where updates are done periodically. Real-time systems are essential for applications requiring up-to-the-minute accuracy.

Conceptual view describes what data is actually stored in the database.

When data is classified based on different time points, it is considered as chronological data.

A Database Management System (DBMS) is software that manages databases, consisting of interrelated data and a set of programs to access, store, and manage that data efficiently.

Hierarchical database systems organize data in a tree-like structure with parent-child relationships, where each parent can have multiple children but each child has only one parent.

File Management Systems (FMS) are flat file systems that don't support relationships between records. Relationships between records are a feature of database systems, not file systems.

File Management Systems (FMS) were the earliest method for storing computerized data, using flat files to organize information before more sophisticated database systems were developed.

Hierarchical database systems organize data in a tree-like structure with parent-child relationships, where each parent can have multiple children but each child has only one parent. Examples include IMS (IBM Information Management System) and Windows Registry. File management systems don't inherently use parent-child structures, network databases use graph structures, and relational databases use tables with relationships.

This is correct because DDL, in oracle, is known as Data Definition Language and it is also used in Oracle to create and remove database objects. It is a SQL plus command and it has an online commands interpreter. The main example of Data Definition Language (DDL) are - CREATE, ALTER, DROP. 

RDBMS means Relational Detabase Management System which provides the user facility to store and retrieve data in a manner consistent with defined model. RDBMS provides the user facility to store and retrieve data in a manner consistent with a defined model. The relational model has three models (1) Structural model to build the model (2) Integrity component and (3). Manipulation component. 

Right answer because DML is one category in SQL Commands which is known as Data Manipulation Language. DML (Data Manipulation Language) is used to manipulate the data in the database. For example-: INSERT, DELETE, UPDATE, SELECT etc.

Right answer because the full name of DCL is  Data Control Language and  there are three SQL Commands in Oracle. These are; DDL(Data Definition Language) , DML (Data Manipulation Language) and DCL (Data Control Language).   

DBMS stands for Database Management System, which is software that manages databases. It provides an interface for users to create, retrieve, update, and delete data in a systematic way. Examples include MySQL, PostgreSQL, Oracle, and Microsoft SQL Server. The other options are incorrect expansions of the acronym.

A view is a virtual table.
