Abstract: One exemplary method of restating telecommunications data by a batch-driven integrated rules module can include receiving batched client data for transforming and loading into a database warehouse to create legacy client data. The method may also include selecting criteria for restating data from a GUI, communicating the criteria to the batch-driven integrated rules module, generating a script based on the communicated criteria for extracting data from the data warehouse that generally includes the legacy client data, extracting the legacy client data from the data warehouse, queuing the legacy client data into a batch, transforming the batched data based on the script, and loading the transformed data in the data warehouse. Additionally, the batch-driven integrated rules module generally includes a rules database, a rules engine, a script generator and a batch tool, and communicates with at least one other database for creating the script.
