Method Oleg Dok means "partitioned view". Microsoft has covered it extensively in SQL 2000 and 2005 documents. Just google this term and you will get a lot of advice.
Basically, if you have N tables with the same schemas, you can create a view above them that combines them together and provides a consolidated view of your data. There is a pretty good blog post describing this. You will encounter some hiccups, especially in terms of performance, so choose indexes wisely, update statistics and monitor them correctly.
