Lightning Data Service in Salesforce manages the data for you and helps you load, create, edit or delete the data in your component. This blog will discuss how to use lightning data services in Lightning Web Component, or LWC.

How To Use Lightning Data Service In LWC In Salesforce

In Salesforce, every web component needs a server to show the data. For example, we have three components showing data about a particular thing. Now, in the general case, there will be three Apex call for the same data, and the database needs to be accessed three times.

If the data on one component changes, the remaining two components will have no information and will keep showing the old data. This can trigger lots of issues. Now, how about having a middleman that fetches all the data from Salesforce, cache it and send the new data to all components? Also, what if the same middleman informs all components about the change in data?

This is exactly what Lightning Data Services do for you. It keeps track of the data and the logs of all changes and keeps all the components informed about the changes so the components can show you the updated data.
