When modifying records by directly setting or changing the properties no validation happens, which is a problem when accepting form data.The following sections will demonstrate how to efficiently convert form data into entities so that they can be validated and saved.Imagine you are tracking all vacant or abandoned buildings in Chicago, each of which was identified by a service request on a specific date.The table has data through March of 2011 and now you want to add in April's data.You can convert a single entity using: When the above data is converted into entities, you will have 4 tags.The first two will be new objects, and the second two will be references to existing records.
