5 Best Practices for Good Database Design
Great database design is necessary for building scale-able , high-performance applications.
If a database works well, everything is on right track. Small decisions, in the beginning, have a huge impact on future development of any system, specially database.
Database Design Best Practices
If you are going to design a database for your next project, then please keep these best practices in mind while working on the project.
To make high-performance and fast systems, it’s critical to normalize database to achieve minimum redundancy. By removing multi-valued and repeated attributes.
2. Descriptive Design
Design a database while keeping future developers and users in mind. Its not a one time disposable task. Many future developers within your company or outsiders may need to work on it in future. Its best practice to clearly describe its design in documents so that people coming after you can easily operate and alter it.
Don’t reinvent the wheel or make things difficult for those who may need to modify the database at some point, which will certainly happen.
Use consistent naming conventions and avoid shortcuts, abbreviations, or plurals.
3. Constraints & Data Integrity
Look into the full range of options such as foreign key, not null etc. to enforce business rules. This can prevent storage of unexpected and in-valid data.
4. Optimize for Speed
You can make you database operations speedy by creating indexes for frequently used queries. Database analyzer can be used to determine if an index or a clustered index is required for your database.
Consider using tools like Elastisearch to speed up searches. Also removing redundancy can help you speed up your database operations, by normalizing it.
5. Multi-tier architecture
Keep your database and Web-server on different physical machines/servers. In addition to freeing up compute resources, it make the database in-accessible for unauthorized users.
Before creating a database for your next project, you must keep in mind these database design best practices. It can dramatically simplify the development process.
