Lightning Data Service provides the ability to listen to data updates that occur in the UI layer and to react and refresh itself with current data. It has a built-in caching ability, and it takes care of create, read, update, delete (CRUD) / Field Level Security (FLS) (security settings configured by the Salesforce system administrator), based on the user context. In this chapter, we will explore Lightning base components. Lightning base components have built-in JavaScript and SLDS support, to accelerate development and prototyping. 

In this chapter, we will cover the following:

• Lightning Data Service 
• Example Lightning components using Lightning Data Service
• Lightning base components
