How to convert existing classes to OA entity?

[Truman]

I have an existing solution with hard-coded test data. I am now ready to persist that classes to the database and wanted to use OpenAccess for this. How can I simply make the below class persistable? Can I just inherit something from OA or why can't I just dragg the class to the "Entity Diagram" for auto-creation? Thanks for any help.

    [DataContract(Namespace = "")]
    public class Element
    {
        [DataMember(Name = "id", EmitDefaultValue = false)]
        public Guid Id
        {
            get;
            set;
        }

        [DataMember(Name = "name", EmitDefaultValue = false)]
        public string Name
        {
            get;
            set;
        }

        [DataMember(Name = "date", EmitDefaultValue = false)]
        public DateTime SomeDate
        {
            get;
            set;
        }
}

Hello Truman,

In order to achieve your goal you may use the Fluent Mapping API. Through this API you can map your existing classes to the relational objects such as tables in the database. Here is a dedicated help section that elaborates on the steps needed to perform the mapping. With the visual designer approach you can either reverse map a database schema or create your entities in the diagram but the classes associated with the diagram are always automatically generated. That is why you cannot drag a user defined class to the diagram.  

We do hope you will find the help section useful. Do not hesitate to contact us should any questions arise.

All the best,
