What's Salesforce? (2019)
This is a good article and history is Salesforce. Another shorter developer focused perspective: Salesforce is a relational database editor. You can create tables, columns, and relationships, app in a nice UI without writing code. You get automatic views and edit forms for records in the tables. And the whole thing is built on a platform where you can write custom sandboxed code to manipulate those records, or expose them over APIs to external systems.The platform is both powerful and pretty clunky. Salesforce development is consistently 20 years behind established best practices. Learning Salesforce means learning the thousands of limitations and broken parts of the ecosystem. And it’s non transferable knowledge.
