Abstract: Saving database storage space includes receiving, using a processor, one or more properties associated with a newly released commodity input at a front-end server; determining whether the one or more properties of the newly released commodity match a standard property unit (SPU), wherein the SPU includes a plurality of properties common to at least two commodities of which data is stored at a back-end server; and in the event that the one or more properties of the newly released commodity match the SPU, storing data associated with binding the newly released commodity with the matching SPU at the back-end server.

Abstract: A system uses a mobile unit to control access to physical spaces with electrical locking devices. An authority means connected to the mobile unit issues authorizing data (AD) access rights, which are sent to an authorization means connected to the authority means, generate a mobile unit alpha-numerical key and send the key and the mobile unit's unique identifier to an operator connected to the authorization means. The operator sends the alpha-numerical key to the mobile unit identified by the unique identifier. An electrical locking device and the mobile unit use an authentication protocol with the alpha-numerical key to authenticate the mobile unit, which, when authenticated, sends the authorizing data (AD) to the electrical locking device. If the authorizing data (AD) comprises an identifier of the electrical locking device, the mobile unit can open the electrical locking device using a communication means in the mobile unit for near field communication.

Abstract: The present invention relates to a system (10) operable to control access to different physical spaces, each provided with an electrical locking device (121, . . . , 12n), with the aid of a programmable, mobile unit (14). The system (10) comprises an authority means (16) operable to issue access rights connected to the programmable, mobile unit (14) in the form of an authorizing data (AD), which authorizing data (AD) is sent to an authorization means (18) connected to the authority means (16), and operable to generate an alpha-numerical key for the mobile unit (14), and to send the alpha-numerical key and a unique identifier of the mobile unit (14) to an operator (20), which is connected to the authorization means (18). The operator (20) is operable to send the alpha-numerical key to the mobile unit (14) identified by the unique identifier.

Abstract: Saving database storage space includes extracting a standard property unit from a database of commodity information and including the SPU in a SPU library, generating a sequence document of the standard property unit and sending the sequence document to a front-end device, determining whether a newly released commodity matches the standard property unit of the sequence document of the standard property unit and in the event that the newly released commodity matches the standard property unit of the sequence document, binding the new released commodity and the matched standard property unit.
