Lightning Data Services (LDS) is a new mechanism in Salesforce that was proposed in winter 2017 to edit, delete, or update records in Lightning Components. LDS reduces the need for APEX methods and improves the overall performance and user-interface consistency. With the help of simple mark-ups, records and the related fields can be quickly loaded to the Lightning Component. In this way, LDS could be taken as a strong consideration before you start with next component development. This can be definitely be taken as the big deal for the future projects.
