(B) Database normalization
(C) Query optimization
(D) Database indexing

Answer 1

The procedures for designing a query in database management include data analysis and visualization, database normalization, query optimization, and database indexing.

Step-by-step explanation:

The procedures for designing a query in database management include:

1. Data analysis and visualization: This involves analyzing the data to identify patterns and trends and visualizing the data using charts, graphs, or other visual representations.
2. Database normalization: This refers to organizing the data in a database to eliminate redundancy and improve efficiency. Normalization involves breaking the data into tables and applying normalization rules to ensure data integrity.
3. Query optimization: This involves improving the performance of query execution by optimizing the query plan. Techniques like indexing, partitioning, and caching can be used to optimize queries.
4. Database indexing: Indexing involves creating indexes on database tables to improve query performance. Indexes enable quicker data retrieval by creating a data structure that allows efficient lookup operations.
