A method and system for performing spereadsheet-like operations in a databas e system is described herein. As explained, a database language is extended to introduce new clauses ("spreadsheet-like clauses"), for defining and executi ng spreadsheet-like operations on data contained within a RDBMS. According to o ne aspect of the invention, in response to receiving a database query that specifies an operation for manipulating data, data from a relational structu re is retrieved and stored in a non-relational structure that can be addressed as a multi-dimensional array. The operation specified in the database query is then performed on the data.
