Abstract: Improved systems and methods for database management using data normalization and defragmentation techniques are provided. At least one exchange processor in communication with an exchange computer system receives market data from the exchange computer system, processes the market information, and transmits the market data to a master processor. The master processor receives the market data, processes the data using at least one normalization process to generate normalized data including an intra-day file and an archival file, and stores the intra-day file and the archival file in the master database. The master processor transmits the intra-day file and the archival file to the at least one regional processor.

Abstract: An object hanger hook for hanging an item, such as a picture, to a vertical or near vertical wall surface utilizing elements that provide internal, generally orthogonal forces against an opposing internal hook surface that help secure and level item to be hung. Embodiments are described each showing force elements and elements to make engagement or release of object hanger hook from item to be hung easy and adjustable.
