Database for a capture system

A method comprising:

• receiving a query for one or more objects captured by a capture system;
• determining whether a query time range exceeds a time range of a set of fast tables;
• and
• searching the set of fast tables if the query time range does not exceed the time range of the fast tables, the set of fast tables containing tags having meta-data related to captured objects.

A method comprising:

• capturing an object being transmitted over a network;
• generating a tag associated with the captured object, the tag containing metadata related to the captured object;
• inserting the tag into a first table of a first set of cascading tables, the first set of cascading tables containing tags generated within a first timeframe;
• and
• inserting the tag into second table of a second set of cascading tables, the second set of cascading tables, the second set of cascading tables being larger than the first set of cascading tables and containing tags generated within a second timeframe, the second timeframe being longer than the first timeframe.

A machine-readable medium having stored thereon data representing instructions that, when executed by a processor, cause the processor to perform operations comprising:

• receiving a query for one or more objects captured by a capture system;
• determining whether a query time range exceeds a time range of a set of fast tables;
• and
• searching the set of fast tables if the query time range does not exceed the time range of the fast tables, the set of fast tables containing tags having meta-data related to captured objects.
