Salesforce Glossary

A plain-language reference for Salesforce admins and users. Definitions of key Salesforce terms, objects, and concepts — with practical examples.

C

Custom Object

A Salesforce database table created by an admin to store data not covered by standard objects.


E

External ID

A custom field used to match external records with Salesforce records during data imports.


F

Formula field

A read-only Salesforce field that calculates its value from a formula expression, updated in real time whenever a record is viewed.


J

Junction Object

A Salesforce custom object with two Master-Detail relationships, used to model a many-to-many connection between two other objects.


L

Lookup Relationship

A non-dependant Salesforce relationship where the child record can exist without its parent. Deleting the parent clears the lookup, not the child.


M

Master-Detail Relationship

A tightly coupled Salesforce relationship where the child record cannot exist without its parent. Supports cascade delete and roll-up summary fields.


O

Object

A Salesforce database table that stores business data - rows are records, columns are fields. Comes in standard and custom types.


P

Permission Set

Grants users access to specific Salesforce features without changing their profile.

Profile

Defines what a user can see and do in Salesforce: object access, field visibility, and app permissions.


V

Validation Rule
