摘要：Methods, apparatus and articles of manufacture to archive data are disclosed. An example method to archive data disclosed herein comprises determining an initial data model representing functional dependencies among attributes of the data, the initial data model having fully interdependent functional dependencies among all attributes of the data, pruning one or more functional dependencies from the initial data model to determine a verified data model, and archiving a transaction included in the data to memory according to the verified data model.

主权项：1. A method to archive data, the method comprising: electronically determining an initial data model representing functional dependencies among attributes of the data, the initial data model having fully interdependent functional dependencies among the attributes of the data; processing the initial data model in a processor-based machine to electronically prune one or more functional dependencies from the initial data model to determine a verified data model, wherein a given functional dependency indicates that a dependent attribute set depends from a key comprising a parent attribute set and processing the initial data model comprises: determining a set of candidate keys comprising respective parent attribute sets;generating a sample of the data;pruning a particular candidate key from the set of candidate keys when the sample indicates that the particular parent attribute set corresponding to the particular candidate key does not have unique entries; andarchiving a transaction included in the data to memory according to the verified data model.
