Abstract: Disclosed is a method, system, program, and data structure for performing a clean operation on an input table. An input data table name indicates the input table. A first column in a table including a plurality of entries and at least one rule definition are processed. Each rule definition indicates a look-up column including a plurality of entries and a clean operation. A determination is made, for each record in the input table column, whether the record matches one entry in the look-up column. If so, the clean operation indicated in the rule definition is performed on each record that matches one entry in the look-up column.

Abstract: The system automatically generates electronic commands necessary to modify or provision different types of program control switches as may be included in a public switch telephone network. A data schema and organization of tables and data structures provide for command generation for each of the different switch types. Additionally, a self-modifying dynamic data structure is used as a common area to communicate information between various programs and formulate the commands due to a limited number of parameters used to communicate information between programs that generate the command for the switches. A technique for verifying switch commands automatically generated by a second new provisioning system is described. A technique is described for automatically extracting switch specific commands and options as generated by a first system for use in populating data stores used in a second system for command generation.
