摘要： A method and a processing device may be provided for creating a shadow database, having a size being approximately a desired percentage of a size of a relational database. Referential integrity of tables of the relational database may be preserved in the created shadow database. A representation of a connected graph may be created, based on a schema description of the relational database, and may be used to find driving tables and related tables of the relational database. Portions of driving tables of the relational database may be copied to corresponding tables of the shadow database and rows of tables of the relational database, related to the copied portions of the driving tables, may be copied to corresponding tables of the shadow database in a number of iterations until the size of the shadow database is approximately the desired percentage of the size of the relational database.

摘要： A simulation may be performed to assess availability of a service in the event of various types of failures. A specification may describe a behavior to be induced on a machine, and a formula under which availability is to be measured. A controller processes the specification and dispatches a request to induce the behavior to a machine on which the behavior is to be induced. An agent on that machine may look up a routine in a simulation library and may use the routine to induce the behavior. Data, such as performance counter values, are collected before, during, and/or after occurrence of the behavior, and are transmitted back to the controller. A report generator applies the formula contained in the specification to the data received to calculate the availability metric, and produces a report containing that metric.

摘要： Strategies are described for sanitizing a data set, having the effect of obscuring restricted data in the data set to maintain its secrecy. The strategies operate by providing a production data set to a sanitizer. The sanitizer applies a data directory table to identify the location of restricted data items in the data set and to identify the respective sanitization tools to be applied to the restricted data items. The sanitizer then applies the identified sanitization tools to the identified restricted data items to produce a sanitized data set. A test environment receives the sanitized data set and performs testing, data mining, or some other application on the basis of the sanitized data set. Performing sanitization on a sanitized version of the production data set is advantageous because it preserves the state of the production data set. The data directory table also provides a flexible mechanism for applying sanitization tools to the production data set.
