How To Optimize Database?

  1. Proper indexing. Index is basically a data structure that helps speed up the data retrieval process overall.
  2. Retrieve the relevant data only.
  3. Getting rid of correlated subqueries.
  4. Using or avoiding temporary tables according to requirement.
  5. Avoid coding loops.
  6. Execution plans.

Why is database optimization important?

Database tuning is essential to easily organizing and accessing database data. Database tuning, or performance tuning, involves optimizing and homogenizing the design of database files and of the database’s environment. This can make data access easier than you imagined.

What is SQL optimization?

Overview of SQL Query Optimization
SQL Query optimization is defined as the iterative process of enhancing the performance of a query in terms of execution time, the number of disk accesses, and many more cost measuring criteria. Data is an integral part of any application.

What is database efficiency?

Data efficiency refers to efficiency of the many processes that can be applied to data such as storage, access, filtering, sharing, etc., and whether or not the processes lead to the desired outcome within resource constraints.

How do we do performance tuning?

Systematic tuning follows these steps:

  1. Assess the problem and establish numeric values that categorize acceptable behavior.
  2. Measure the performance of the system before modification.
  3. Identify the part of the system that is critical for improving the performance.
  4. Modify that part of the system to remove the bottleneck.
