The goal of dzo is to treat application database objects the same way the application's source code is treated, with respect to development, revision control, and deployment. Dzo uses a text file that contains native create statements for all database objects and compares them against the actual database-schema. As a result, dzo creates the SQL statements needed to update the database schema (or you can let dzo execute the SQL statements directly). If your application lives in a Tomcat or Java EE application server, dzo has a servlet that controls the deployment process, inspects and executes the necessary database changes, and finally deploys the application. Dzo currently works with HSQLDB, MySQL, Oracle, PostgreSQL, and SQL Server (more to come).
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.
