Mappings can be entirely created in code. Mappings can be created from scratch or mappings can be augmented by generating the mapping first.

Manual Mapping

Dim db As IDataHelper = DataHelper.SessionFactory()

Dim table As New Table(GetType(Person))

table.TableName = "People"

Dim field As New Field(table, "FirstName", "FirstName")

table.Fields.Add(field)

db.Mapper.ObjectMap.Add(GetType(Person),table)

Partially Automatic Mapping

Dim db As IDataHelper = DataHelper.SessionFactory()

Dim table As Table = _db.Mapper.GetObjectMap(GetType(Customer))

table.Fields.First(Function(o) o.PropertyInfoString = "Name").DatabaseType = DbType.String
