What is the difference between Salesforce Platform Licence and Salesfore Licence?

Hi,

Salesforce licenses are designed for users who require full access to standard CRM and Force.com AppExchange apps. CRM apps are anything that requires access to Standard Objects like below:
Leads
Opportunities
Forecasts
Cases
Solutions

Salesforce Platform licenses are designed for users who only need access to custom apps, and NOT the standard CRM functionality. Salesforce Platform users DO have access to the “core” Salesforce Standard Objects and functionality, like…

Accounts
Contacts
Reports
Dashboards
Documents
Custom Objects & Tabs
