Abstract: Maintaining, for each target key in a key-value computer database, a signature policy; creating a transaction candidate in the database based on a transaction context submitted to the database by a first user, the transaction candidate comprising: a key, a value comprising a transaction content and a signature of the first user, and a signors list of additional one or more users who are required to co-sign the transaction candidate before the transaction candidate is committed in the database as a transaction, wherein the signors list is automatically computed based on the signature policies of the one or more target keys; collecting a signature for the transaction candidate from at least one of the additional one or more users, according to the signors list; verifying that all signatures required by the signors list have been collected; and in response to the verification, committing the transaction content of the transaction candidate.

Abstract: A method implemented in a computer infrastructure having computer executable code tangibly embodied on a computer readable medium being operable to associate each of a plurality of tenants with a respective virtual portal and individually meter virtual portal usage at each respective virtual portal. Additionally, the computer executable code is operable to determine a fee amount for the each of the plurality of tenants based on the individually metered virtual portal usage.

Abstract: One or more location updates from one or more user devices can be associated with one or more grid elements dividing a geographic area. Each location update corresponding to a set of user device data can be stored in a hashtable according to grid element. The hashtable can be resized based on the number of grid elements containing one or more sets of user device data. A set of grid elements can be determined to overlap a geofence, and zero or more sets of user device data can be retrieved from the hashtable corresponding to zero or more user devices located within the geofence.

Abstract: Managing cooperative computer software applications by applying a link analysis algorithm to a data set including identifiers representing a plurality of computer software applications and including indicators of operational relationships between the computer software applications, thereby associating a cooperation value with each of the computer software applications represented within the data set, and notifying a computer software application manager of the computer software applications and their associated cooperation values.

Abstract: Techniques for managing a meeting calendar entry are provided. The techniques include scheduling a meeting by sending an invitation to one or more individuals, wherein the meeting is scheduled by a primary organizer via a meeting calendar entry, defining one or more secondary organizers for the meeting, and facilitating the one or more secondary organizers to manage a meeting calendar entry for the meeting.

Abstract: A system and method of propagating subscriber and offer identities in URL patterns for multi-tenant systems are provided. The method in one aspect comprises intercepting a request for accessing a web service, the request being in a virtual URI format that includes at least a service access point, subscriber identity and offer identity. The method may further include resolving the virtual URI to determine customer identity, offer identity and destination information, invoking a web service defined in the destination information and returning results of the invoking step. A system, in one aspect, may comprise a router operable to receive a virtual URI, and a route rules database operable to store rules associated with resolving the virtual URI, the router further operable to invoke a service associated with a service access point specified in the virtual URI and return results of the invocation to a requestor.
