A working database is crucial for internal business operations. And one crucial part of that database is its design. Not sure where to start? No problem. Here are five database design steps to help.
Determine the purpose of the database
The very first thing you must do is decide the purpose of your database. You need to determine what it will be used for, how you expect to use it, who you expect to use it, etc. This will help you develop a mission statement and prepare for the remaining steps.
Find and organize the information
Once you have figured out the purpose of your database, you’ll need to gather the data that needs to be stored there. After you gather the necessary information, you need to organize it. It’s usually easiest to organize the information by breaking each piece into its smallest useful parts.
Create tables for the information
Once the information is organized, you’re going to want to divide up the information into tables. Separate the data into major entities or subjects. Then, each subject will become a table. Label each table with the subject within that table.
Establish relationships between the tables
It can be hard to use a database with independent or unrelated tables. It is best to look at each individual table and decide how the data within relates to the data in other tables. You then can add fields to the tables or create new ones to clarify the established relationships so everything is connected.
Redefine your design
One of the last database design steps is to take a step back once you’ve “completed” the database. You want to scan it and analyze the design for any errors. Run the database with the tables and record to see if you can get the results you want. You should then make adjustments to get the final result you desire.
