SELTA@Etersoft enables programs that store data in MS SQL Server to work with PostgreSQL. It translates SQL queries from the T-SQL dialect (used in MS SQL Server) to pl/pqSQL (used by PostgreSQL). Though SELTA@Etersoft is universal, it needs improvement to support concrete applications. At the moment, the translator is oriented to the popular Russian accounting system «1С:Предприятие 7.7». If your application can store data only in MS SQL, and you want it to be compatible with PostrgreSQL, support for your application can be implemented.
