The program supports import from two different formats.

In the first case source file must contain one row per field:
FiledName[,DataType[,Size]]

Sample input data:
OrderID,Integer
Customer,String,32
OrderDate,Date

In the second case, the program accepts sample file: Excel or plain text. This file must have the same structure as should be created. The import option for plain text supports tab-delimited, comma-separated and fixed width file formats as the example.
