What is Data Source Stream?   

Data Source Stream (DSS) is a middle data format designed specially for data interchange purpose. DSS complies with data components such as ODBC, BDE and ADO. It therefore supports almost all the common databases on the market.

Two reasons justify our method. Firstly, company does not need to update or replace its existing MIS to meet EDI requirements. Low cost and easy implementations are essential for EDI popularity. Secondly, as long as these components support any new database, DSS also support it. That makes future EDI application development much easier.

DSS Advantages.......

DSS is a simplified format temporarily existed when converting from source database to target database. The advantages are

• It is compatible with all the databases which ODBC, BDE and ADO supports.

• It supports relational database and can pack two relational tables or three into one file. It also keeps the table relationship in the file and can unpack the file back to two or three tables.

• It is faster using DSS as the middle format. If you copy a Paradox table to dBase table, for example, indirect copy through DSS is more than 50 % faster than direct copy. Do you believe that? You can test it by using DBEditor.

• It saves space. You can backup two tables into one file and still be able to query in DSS format.

• It supports virtual schema. You can define DSS field name by .INI text file. No other tool is required.

• It can be queried and updated just like any database.

• The database management tool supporting DSS is available named DBEditor.
