Some of the answers are incorrect ma'am. like what is the oldest database model? It is hierarchical but you said something else. please provide such productive videos after much proofing reading. thank you for the video ma'am. correct me if I am wrong
The IDS system, which is often presented as the first DBMS, was created by Charles Bachman and was released in 1964. It had a “network” data model, which means that data was stored in a graph-like structure of linked nodes (we will refer to network subclass as NnDBMS later).
Q79) wrong correct answer is D) Candidate key A candidate key is a set of columns in a table that uniquely identifies every row within that table. Each candidate key must satisfy two properties: uniqueness and minimality.
A candidate key is a single attribute that uniquely identifies a record in a table. A super key is a combination of multiple attributes that uniquely identify a row in a table. (Bro achchha se padh lo isko ma'am ka answer sahi hai )
Q71) answer is wrong: correct answer is C) Hierarchical The oldest DB model is the Hierarchical model. It was developed in the 1960s and was one of the earliest models for organizing and representing data in a database. In the Hierarchical model, data is structured in a tree-like manner, where each record (or data element) has a one-to-many relationship with the records below it.
Data Manipulation Language Therefore, the Data Manipulation Language is used in the application programs while requesting the data from the database management system.
