First, the tried and true response - I highly recommend reading the documentation. There is help info there.
Second, a brief description: Schema files are text files that represent record layouts, just like table definitions in DataStage. They provide a more dynamic interface. For example, you could have a generic export program that takes a table name as input (for the database read stage) and a schema file that is passed to the sequential file stage as output.
Again, please read the documentation - it will be far more detailed and probably provide better examples.
