Abstract
Systems and methods of processing queries for column-oriented database systems involve processing the queries to identify which of values of column data are to be accessed for the query. A select bitmap is then generated having k bits wherein each bit corresponds to one of the values of the column. The select bitmap is generated such that each bit representing a value of the column data that is to be accessed for the query has a first value and each bit representing a value of the column data that is not to be accessed for the query has a second value. Encoded values are then extracted from memory for each of the values represented in the select bitmap by a bit having the first value. The extracted encoded values are decoded to generate decoded query data. The decoded query data is then processed to generate result data.
