This class represents the database managing functionality in client-side scripts. For example, auto population of the fields, displaying some form elements and setting mandatory attribute for them regarding the values set in the Reference Fields.The client SimpleRecord class enables a user to manage both records in the tables and fields of single records.
In this class, client-side queries are executed on the server. That is, to get a record data, a request from the client side should be sent to the server.
The functionality of the client-side SimpleRecord class can be not enough for managing some business tasks. In this case, use the SimpleAjax class or Table API.
