have 100 fields in a table, then the corresponding PO has 100 attributes. However, as long as we display 10 fields on the interface, the client uses WebService to fetch the data, and there is no need to pass the entire PO object to the client, we can pass the result to the client with a DTO with only these 10 attributes. This also does not expose the service-side table structure. After reaching the client, if the object is used to display the corresponding interface, then its identity will be c
