Abstract:
A method for indexing and storing time-stamped normalized event data in a database, the method comprising steps of:allocating an area of database storage sufficient to retain an amount of normalized event data over a predetermined retention time H; dividing the area of database storage into H/P number of unique storage locations, each unique storage location being addressable by a unique index number, where P corresponds to a duration of a chunk of data; collecting time-stamped normalized event data in P-duration chunks, each P-duration chunk having a time stamp T associated therewith and indicating a total time measured from a fixed point in time; assigning one of the unique index numbers to each of the P-duration chunks collected in said step of collecting according to index number=T/P modulo H/P+Offset, where Offset is one of a constant value or a periodic function of period H; and storing each P-duration chunk of data in a database in said area of database storage according to the index number assigned in said step of assigning.
