Abstract: A computer-implemented system and method are provided for automatically determining rebate eligibility for purchased products. In one example, the purchased products may be travel-rebated products such as booked air travel itineraries. A database stores purchase information associated with purchased products purchased at corresponding purchase prices. A product administration system having a computer software-based product administration application interacts with the database and purchase information of a first purchased product is compared with purchase information of subsequently purchased products. The product administration application interacts with the database to determine if the first purchased a product matches a subsequently purchased product based on a set of matching criteria.

Abstract: A database management system and method are provided. In one example, the database management system may include a source database, a target database, and a replication system operable to identify a difference in structure between the source database and the target database and change the structure of the target database to correspond to the structure of the source database. In such an example, the structure of the target database may be alternatively changed manually. In another example, the source database may include structure and data, and the replication system may be operable to replicate at least one of the structure and the data to the target database without storing the at least one of the structure and the data in an intervening database as the at least one of the structure and the data is transmitted from the source database to the target database.

Abstract: A system and method for loading a new data and searching data sets to identify data elements with the data set that meet user defined criteria. A notification that new data set is available is received by a first server, the new data set is transferred to the first server, and the first server stores the new data set and an old data. At least a portion of the old data set and the new data set are transferred from the first server to the second server, which is in communication with the first server, which stores the portions of the old data set and new data set. The second server receives user search requests and: (1) processes queries in response to the user search requests by running a first search process using the portion of the old data set prior to receiving a command to switch to the new data set; and (2) processes queries in response to the user search requests by running a second search process using the portion of the new data set after receiving the command to switch to the new data set.
