Step 1: Understand what an index is. An index is a database object that improves the speed of data retrieval operations on a database table.
Step 2: Know the SQL command to create an index. The command is 'CREATE INDEX'.
Step 3: Learn the basic syntax of the 'CREATE INDEX' statement. It usually looks like this: 'CREATE INDEX index_name ON table_name (column_name);'.
Step 4: Replace 'index_name' with a name you want to give to your index, 'table_name' with the name of the table you want to index, and 'column_name' with the name of the column you want to index.
