Abstract: Electronic content items such as electronic books are enhanced by identifying citations within the content items, identifying sources of the objects of the citations, and associating the citations with such sources so that readers of the content items can easily purchase or otherwise obtain the citation objects. The citations may be updated as new products become available or information related to the products changes over time.

Abstract: Database Definition Language (DDL) transactions are defined that include one or more DDL operations that are to be executed to modify aspects of a relational database, such as its structure. If performance of one or more of the DDL operations in a DDL transaction fails, then the changes made to the relational database by some or all of the DDL operations may be reversed. Instructions and state information may be generated and stored prior to, during, and/or following the execution of a DDL operation that may be utilized to reverse the changes to a relational database made by the DDL operations. User interfaces might also be provided for defining, selecting, editing, and executing DDL transactions, and for providing information relating to the execution and rollback of DDL operations in a DDL transaction.

Abstract: Disclosed are various embodiments for identifying a table of non-decoy data matching a set of criteria. Decoy data is inserted into the table of non-decoy data. The decoy data is detected in a result comprising the decoy data, the result generated in response to an access of the data store. An alarm is generated based at least upon the result.
