Introduction to Salesforce

Salesforce

Cloud-based CRM has grown to a $250 billion dollar industry and Salesforce claims about 20% of the market share owing to the fact that this was the first company to offer a cloud-based CRM platform. If your business is building a complete digital transformation, then it’s no surprise that you’re already looking at Salesforce to help manage your customer and partner relationships. 

Salesforce has been dominant in its field while also pioneering new ways of using technology. The company offers a wide range of cloud-based services through its customer success platform, including:

  • Salesforce automation
  • Digital commerce
  • Community management
  • Analytics
  • Financial services cloud
  • Marketing cloud
  • Etc.

To begin with, let’s first look at the concept of a data extension.

What is a Data Extension?

A data extension is simply a table/relational database that contains all of your company information, for example, customer data like; Name, Address, Age, Gender, Email, City, etc. In practice, you can put anything in a data extension and keep track of that information, just like you can in an Excel Spreadsheet. As a matter of fact, a data extension is exactly like an Excel Spreadsheet except that the data is stored in the Salesforce Marketing Cloud.

  • A Standard data extension allows you to create custom fields and data types in your table.
  • A Filtered data extension allows you to filter fields, measures, and filters for a sendable data extension from a source data extension. You have to have a Standard data extension to create a Filtered data extension.
  • A Random data extension allows you to randomly select subscribers from a source data extension. Just like with a Filtered data extension, you need a Standard data extension to derive a random data extension.
