# Object Cheatsheet

At a glance, see how objects compare to each other.

## Object Groups

- Common Objects: Used to store data available in any standard org for any cloud. Optimized for ACID transactions. Relational and transactional database that scales to millions of records.
- High-scale objects: Used for large numbers of transactions and data storage over time
- External Objects: Used to represent data stored outside Salesforce
