In the Testa EV database design described in the previous question, please complete a field specifications form for the field 'Model_Cost' of the table 'Model_T'. The field records the cost of producing a specific EV model. Because its data come from the cost data of specific parts used to build the model, its value can be entered later and editing is allowed (null is allowed). The field value is required. Only decimal numeric data are supported for the entered value. The field can store a maximum of 10 digits (including 2 decimal places). The user of the database (data analyst) is responsible for entering and maintaining the data. No specific range of values is specified for this field. You should enter 'N/A' (or leave it unchecked) for elements that are not applicable.
