1. What is Normalization? Types of normalization?
- A.
Join the tables
- B.
Move the data into tables.
- C.
Split the table to reduce duplicates and it has five types.
- D.
None
Correct Answer
C. Split the table to reduce duplicates and it has five types.Explanation
Normalization is the process of organizing data in a database to eliminate redundancy and improve data integrity. It involves splitting a table into multiple smaller tables to reduce duplicates and ensure each table represents a single entity or concept. This helps in reducing data anomalies and improves the efficiency of data storage and retrieval. There are five types of normalization, namely First Normal Form (1NF), Second Normal Form (2NF), Third Normal Form (3NF), Boyce-Codd Normal Form (BCNF), and Fourth Normal Form (4NF).Rate this question:

- B.
Equi join and cross join.
- C.
Right outer join.
- D.
All above.
Correct Answer
D. All above.Explanation
The correct answer is "All above" because there are indeed different types of joins in SQL, including inner join, outer join, self join, equi join, cross join, and right outer join. Each type of join serves a different purpose and is used to combine data from multiple tables based on specified conditions.Rate this question:

1. What are the advantages of using stored procedure?
- A.
A. Pre executable program.
- B.
B. We can get the data.
- C.
C. Security.
- D.
D. It is similar to function.
Correct Answer
A. A. Pre executable program.Explanation
Stored procedures are advantageous because they allow for pre-execution of a program. This means that the procedure can be compiled and optimized before it is executed, leading to improved performance. Additionally, stored procedures can be reused, reducing the need to rewrite code. They also enhance security by allowing access to the database through the procedure rather than directly. Finally, stored procedures are similar to functions in that they can return values and be used in other queries or procedures.Rate this question:

1. Define Index?
- A.
A. Predefined pointers to data page.
- B.
B. It is primary key.
- C.
C. It is foreign key.
- D.
D. None.
Correct Answer
A. A. Predefined pointers to data page.Explanation
The correct answer is "a. Predefined pointers to data page." In a database, an index is a data structure that improves the speed of data retrieval operations on a database table. It does this by creating a copy of a portion of the table's data and storing it in a separate structure. This separate structure contains pointers to the actual data pages, allowing for faster access and retrieval of specific data. Therefore, an index can be defined as predefined pointers to data pages.Rate this question:

1. Define having clause?
- A.
A. It is similar to where but must use group by clause.
- B.
B. It is equal to where clause.
- C.
C. None.
- D.
D. It is equal to from clause.
Correct Answer
A. A. It is similar to where but must use group by clause.Explanation
The having clause is used in SQL to filter the results of a query based on conditions that involve aggregate functions. It is similar to the where clause, but it can only be used in conjunction with the group by clause. The having clause allows you to specify conditions that apply to groups of rows, rather than individual rows. This is useful when you want to filter the results based on the result of an aggregate function, such as finding groups with a certain sum or count.Rate this question:

1. What are the basic functions system databases?
- A.
A. To create functions.
- B.
B. To create stored procedure.
- C.
C. To maintain metadata information.
- D.
D. None.
Correct Answer
C. C. To maintain metadata information.Explanation
System databases in a database management system (DBMS) are responsible for maintaining metadata information. Metadata includes information about the structure and organization of the database, such as tables, columns, indexes, and relationships. System databases store this information and allow the DBMS to access and manage it efficiently. The functions of creating functions and stored procedures are typically performed by user databases, not system databases. Therefore, the correct answer is c. To maintain metadata information.Rate this question:

A. Extract, Translation, Loading.
- B.
B. Extract, Transformation , Loading
- C.
C. Both a and b.
- D.
D. None.
Correct Answer
B. B. Extract, Transformation , LoadingExplanation
The correct answer is b. Extract, Transformation, Loading. The ETL process involves extracting data from various sources, transforming it to fit the desired format or structure, and loading it into a target system or database. Extraction involves retrieving data from different sources such as databases, files, or APIs. Transformation involves cleaning, filtering, and manipulating the data to ensure its quality and consistency. Loading involves transferring the transformed data into the target system or database for further analysis or reporting.Rate this question:

- C.
C. None.
- D.
D. Both a and b.
Correct Answer
A. A. For loop based on conditions and for each loop based on objects collections.Explanation
The correct answer is a. For loop based on conditions and for each loop based on objects collections. This answer correctly identifies the key difference between a for loop and a for each loop. A for loop is based on conditions and can be used to iterate over a collection of objects based on specific conditions. On the other hand, a for each loop is based on object collections and is used to iterate over all the objects in a collection without the need for conditions.Rate this question:
