A method, system, and computer readable medium for collecting statistics associated with data in a database are disclosed. The computer readable medium implements the method comprises determining an amount of memory needed to collect statistics for data associated with a defined data type in a relational database.

The amount of memory is allocated as determined for collecting the statistics for the data of the defined data type. A statistics collection is performed for the data of the defined data type in a single pass through the database and within the amount of memory which has been allocated. The performing includes at least determining a total number of instances of at least one path-identifier associated with a given value within a given set of documents.
