Abstract
A system for implementing virtual columns in a column store database is provided. In some implementations, the system performs operations including accessing a database table in a column store database system, the database table comprising at least one virtual column, the column store database system storing data in a column-oriented structure. The operations further include calculating a value for the at least one virtual column based on at least one existing column of the database table, the calculated value mapped to a row identifier associated with a row of the database table. The operations further include providing, in response to a query, the calculated value to a user interface, the query associated with the row identifier.
