Database normalization is the process of organizing the columns (attributes) and tables (relations) of a relational database to reduce data redundancy and improve data integrity. Denormalization is the reverse process of the normalization process. Denormalization works by adding redundant data or grouping data to optimize the performance. For this assignment:
- Denormalize the following three tables, into one table called tbl_location:
- tbl_state contains (state_id,state_name)
- tbl_county contains (conty_id,county_name)
- tbl_city contains (city_id,city_name).
- Discuss the steps you took to create the new tbl_location table and if the new table design increased or decreased the performance of the query.
Take a screen shot of the new combined table and attach it (via a Word document) with your response in your initial post.
