Q2. What are the different types of Normalization in DBMS?
Ans. 
Normalization is a process in DBMS that eliminates data redundancy and ensures data integrity.
• Normalization is used to organize data in a database efficiently.

• There are different normal forms, such as 1NF, 2NF, 3NF, BCNF, and 4NF.

• Each normal form has specific rules and dependencies to achieve data normalization.

• Normalization helps in reducing data duplication, improving data consistency, and simplifying database mainte...read more

Q3. What do you know about Views in mySQL?
Ans. 
Views in mySQL are virtual tables that are based on the result of a query. They can be used to simplify complex queries and provide a layer of abstraction.
• Views are created using the CREATE VIEW statement.

• They are stored in the database and can be accessed like regular tables.

• Views can be used to hide complexity by encapsulating complex queries into a single view.

• They can also be used to restrict access to certain colu...read more

Q4. What are Stored Procedures?
Ans. 
Stored Procedures are precompiled database objects that contain a set of SQL statements and can be executed with a single call.
• Stored Procedures are used to encapsulate and execute frequently used SQL statements.

• They improve performance by reducing network traffic and optimizing query execution.

• They can accept input parameters and return output values.

• It consists of three parts: header, payload, and signature.

• The header contains the algorithm used to sign the token.

• The payload contains the claims or information about the user.

• The signature is used to verify the integrity of the token.

• J...read more

Q3. What is the difference between Webtokens and APIs?
Ans. 
Webtokens and APIs are both used in web development, but they serve different purposes.
• Webtokens are used for authentication and authorization, providing a secure way to transmit user information between client and server.

• APIs (Application Programming Interfaces) are sets of rules and protocols that allow different software applications to communicate and interact with each other.

• Webtokens are often used within APIs to...read more

Q5. If the data in a table is already normalized, what can we do to further optimize is?
Ans. 
Further optimization of normalized data can be achieved through indexing, denormalization, and caching.
• Create appropriate indexes on frequently queried columns to improve query performance.

• Consider denormalizing the data by combining related tables to reduce the number of joins required.

• Implement caching mechanisms to store frequently accessed data in memory for faster retrieval.

• Use materialized views or summary tables...read more

Q6. How do you perform indexing in a database, which column you use for indexing?
Ans. 
Indexing in a database improves query performance by creating a data structure that allows for faster data retrieval.
• Indexing involves creating an index on one or more columns of a database table.

• The column used for indexing should be chosen based on the frequency of data retrieval and the cardinality of the column.

• Columns with high selectivity and frequent data retrieval are good candidates for indexing.

• Examples of co...read more
