Salesforce Classic: Salesforce Classic is simply a term used to DIFFERENTIATE between the new and old user interfaces. It's essentially the same stage that we've been using for a long time. With the passage of time, the expectation to learn and adapt grows, and we can more easily discern the gaps between the customer's requirements and the services that they are receiving. It is critical to stay up with advancements, enhancements, and customer requirements during this particularly delicate phase of time innovation. It's also critical to update the user interface to make it easier to use and to keep it up to date with the latest technology.

Following are the differences between Salesforce Lightning and Salesforce Classic:

• User Experience Improvements: The user interface is one of the most SIGNIFICANT differences between Salesforce Classic and Salesforce Lightning. The latter provides a far superior user interface to its users, including features such as drag-and-drop FUNCTIONALITY that may be accomplished without the use of any coding. Instead of engaging a Salesforce DEVELOPER to construct or change a Salesforce page, an admin can quickly REARRANGE the page components to their preference. In addition, Lightning helps to reduce the requirement for Visualforce for each activity. Any code that is produced during development must be tested before being deployed. In the event that a bug is missed, the code is sent back to the developer to be fixed, and the process begins again. These types of time-consuming activities can be avoided with Salesforce Lightning.
• Enhanced Security: Salesforce Lightning provides a higher level of protection. LockerService, for example, is a feature that allows Lightning components to interact with each other by separating them. This contributes to the platform's protection against harmful data. In Classic mode, there is no such feature.
  Permissions work differently in Salesforce Lightning as well. Users cannot change their assurance levels in-session, for example, from standard to high. They'll have to log out of the Lightning platform and log back in user authentication with a higher level of certainty.
• Einstein (Wave) Analytics: While an improved and upgraded user interface and security are compelling arguments, Salesforce Lightning also gives consumers access to Einstein (Wave) Analytics reports, which the Classic does not. Salesforce Classic reports use common reporting types to create graphs, charts, and lists. These dashboards show to be a terrific solution for capturing a view of crucial indicators when the data is refreshed.
• Progressive platform: Lightning was criticized in its early days due to its transition and compatibility concerns with objects, custom code, and apps. But those days are behind, and the platform has developed to accommodate any custom metadata items, making it much easier for businesses to migrate their existing apps and workflows without having to start from scratch.
