WARP4 has been conceived to support other applications, running beside them, on the same machine, without introducing latency, setting technological constraints or increasing the server workload.
In order to achieve such a goal, WARP4 has been designed around the following 10 Basic Concepts:

1. Synchronous
   In WARP4 every request is synchronously served.
   
   
2. Near Zero Latency™
   Each request is served in less than 5 msec.
   
   
3. Session / Transaction Based
   a. Usage events related to the same session are correctly managed.
   b. Each session can be managed as a transaction.
   c. Several simultaneous transaction based sessions for the same user are allowed.
   
   
4. Statefull
   Subscriber's status (e.g., balance, membership, discount levels) can be managed.
   
   
5. Power
   For instance, on a single CPU Linux server having a 1,000,000 subscribers database WARP4 can rate, with near zero latency, up to 20,000,000 events/hour (working as Balance Manager) or 200,000,000 events/hour (providing Advice of Charge) in a real world scenario.
   
   
6. Value Chain On Line
   Every rating related information is made available as soon as the rating event is processed (e.g., partner share, client's bonus points).
   
   
7. Flexibility
   Business and Operational scenarios can be completely configured via GUI.
   
   
8. Agility
   WARP4 size is negligible and its persistence has been designed to be independent from the database technology. WARP4 can be run wherever and beside any other application.
   
   
9. Multiunit
   Rating units can be freely defined (e.g. currencies, bonus schemes, balance types).
   
   
10. Integration easiness
    WARP4 provides a wide range of APIs on several technologies: web services, RMI and Java. Parlay guidelines are completely taken into account.
