- Database design - designed database will ensure long-term scalability and ease of data maintenance. There are several basic steps in database design:
- one to one - to-many-relationship/) or [many to many](https://vertabelo.com/blog/many-to-many-relationship/). For example, a book might have one or more authors, and an author might write one or more books. You can represent these relationships by creating a foreign key in one table that references the primary key in another table.
