Chapter 15 | Databases How to Approach: You could be asked about databases in a variety of ways: write a SQL query, design a database to hold certain data, or design a large database We’ll go through the latter two types here Small Database Design Imagine you are asked to design a system to represent a large, multi-location, apartment rental company What are the key objects? Property Building Apartment Tenant Manager How do they relate to each other? Many-to-Many: » A property could have multiple managers, and a manager could manage multiple properties One-to-Many: » A building can only be part of one property » An apartment can only be part of one building 7 9 What is the relationship between Tenant and Apartment? An apartment can obviously have multiple tenants. Can a tenant rent multiple apartments? It would be very unusual to, but this could actually happen (particularly if it’s a national company). Talk to your interviewer about this. There is a trade-off between simplifying your database and designing it to be flexible. If you do assume that a Tenant can only rent one Apartment, what do you have to do if this situation occurs? Large Database Design When designing a large, scalable database, joins (which are required in the above examples), are generally very slow Thus, you must denormalize your data Think carefully about how data will be used—you’ll probably need to duplicate it in multiple tables Cracking the Coding Interview | Knowledge Based
