tiva is a database system for time-series sensor data.
With the distributed sensors with mobile phones and other devices, we can get various information about our living environment. The stored sensor data enable us to realize context-aware services.
"Tiva", a database system for time-seires sensor data, provides high-speed data insertion and time-range search queries.
Store pairs of time and sensor data
Tiva stores time("2010/07/31 10:00:00") and sensor value(ex: acceleration: "1.032451, 0.121212, 0.041234") and provides fast insertion of record, time-range queries, using sparse index ,deferred update and better compression.
SQL like queries
Tiva also provides SQL like queries. You can manage data like
・"INSERT INTO sampledb VALUES('2010/07/31 10:00:00', 100)"
・ "SELECT FROM sampledb WHERE time = '2010/07/31 10:00:00' "
High-speed Performance and Time-range Search
Sensor data often be used in time-range set to see trends or changes of them. You can query like
・ "SELECT FROM sampledb WHERE time between '2010/07/31 10:00:00' and '2010/07/31 11:00:00'"
.
tiva strage
tiva strage is a dbm for sensor data. It will provide libraries for some languages.
tiva sql
tiva sql is a wrapper on tiva storage. It enables you to use SQL like queries.
