please improe this writing: There is a big difference between time it takes to perform each of the queries. After adding primary key to each table, the time to perform each of the queries was faster than what it was before. Creating a primary key help identify unique data. Primary key in a table is a crucial column used in queries, optimized for fast performance with an associated index. The primary key index is the most efficient access path for a table. They are created after a table is created, optimizing search speed. Once constructed, indexes are internal structures that the user cannot actively access. If the internal query optimization procedure concludes that using an index will increase search efficiency, then it will be employed. When SQL queries are internally ready for execution, they automatically undergo optimization. The best way to run each query is determined by the optimization process, which may or may not include using a relevant index. Read and write speeds are exchanged in indexes. To put it another way, having more indexes makes it possible to query the data more quickly, but inserting and updating entries takes longer. An index's main function is to present the index's data in an ordered manner, which expedites the query process. During a search It’s similar like searching in a paper phone book when you use a database index. The fact that each entry is placed in a well-defined order is the main idea. Because each entry's position is determined by the sort order, locating data in an ordered data set is quick and simple.

The temporal efficiency of query execution is a crucial parameter in database optimization. Primary key integration into tables has evolved as a solution for increasing efficiency. This improvement in query performance, especially in terms of speed, is driven by a number of aspects related to the fundamental concept of primary keys.
