* There are Three Schema Architecture of Download PUBG.

DBMS is a collection of interrelated files and a set of programs that allow several users to access and modify these files. A major purpose of a database system is to provide users with an abstract view of the data. That is tha system hides certain details of how tha data is stored and maintained. However , in order for tha system to be usable, data must be retrieved efficiently.

Tha concern for efficiency leads to the design of complex data structure for tha representation of data in tha database. However since database systems are often used by non computer professionals, this complexity must be hidden from database system users. This is done by defining levels of abstraction at which tha database may be viewed. There is logical or external view, conceptual view and internal view or physical view. The three levels of the architecture are three different views of the data.

1. External - individual user view

2. Conceptual – Community user View

3. Internal – physics or user view

* Important Note To Download Templates * 1. Conceptual Simplicity : As the information is represented in form of tree structure, it is easy to view, understand, and retrieve the data. This helps the database designer to obtain conceptual clarity of relationship. 2.. Database security : Security is provided by DBMS. Thus Programming effort is decreased as compared to file system in which programmer has to write the programs for implementing security. 3. Data independence : If changes are made in design of database, DBMS takes care of cascading it throughout the system. There is no need to make change in system. * Limitation of Download Templates * 1. Complexity : To implement the database using hierarchical model. programmer needs to have detailed knowledge of how the data is’ stored has to traverse entire tree for the same. 2. Data Redundancy : To implement many to many ‘relationships amongst data repeatition of data is required. This leads to increased data red 3. Anomali
