    摘要: A reasonably-sized testing database instance can be efficiently replicated and maintained for a very large production database while retaining the characteristics and cross-sectional data. The performance characteristics are maintained in order to provide for proper testing of the production database for various application programs. Statistics on the type of data distribution for the customer data are obtained, allowing for parameters to be determined which can be used to store data only near the endpoints of the distribution (and/or at other key locations). In this way, a substantial amount of data skew is retained in a much smaller instance of the production database, allowing for easier performance testing, upgrade testing, etc.
