Explain the importance of good database design.

Question

What will be an ideal response?

Answer 1

Creating a well designed database requires careful planning. First, decide on the main goals of the database. What is its purpose? What data will it store? Once you decide this, you need to organize the database into categories of data. For instance, if your database will track information about your sports league, you might have categories called Teams, Players, Coaches, and Games. You can then turn each of these categories into tables in your database. Then, you need to define fields and the data types for each table. Remember that each table must have a primary key field that uniquely identifies each record from any other in the database. Once you have created your tables, you need to decide how each table relates to the others in the database and set up appropriate relationships between them. You might need to add new fields to the tables to create these relationships. Creating a well designed structure for your database will make sure that your data is easy to access, maintain, and update.
