Although data broadcast has been shown to be an efficient method for disseminating data items in mobile computing systems, the issue on how to ensure consistency and currency of data items provided to mobile transactions (MT), which are generated by mobile clients, has not been examined adequately.
Other significant dimensions such as completeness, consistency, and currency are necessary in order to fully characterize the quality of information.
Besides ensuring data consistency and maximizing currency of data to mobile transactions, OUFO also aims at reducing data access delay of mobile transactions using client caches.
Synchronization can be characterized at a more refined level by looking at specific aspects of the shared consistent view of uniquely referenced objects: timeliness, currency, latency, consistency, coherence, and deterministic data access.
Fugini, et al. [25] define completeness, currency, internal consistency, timeliness, importance, source reliability and confidentiality for cooperative web information systems.
And "consistency is the only currency that matters".
Having stable locations to exchange the currency also creates consistency.
It shouldn't be surprising, therefore, that so few can anticipate real currency crises with any consistency.
Pointer: Authenticity and consistency have fast become our most valuable currency.
The rating values listed in the matrix reflect the combined rating of each data source for both the purposes of base mapping and analysis based on an evaluation of its scale, reliability/accuracy, currency, availability, uniqueness, and global consistency.
