Patent ID: 8762624

Claim:
A data management system comprising: a first non-volatile memory section divided into a plurality of sequentially arranged memory locations, each identified by an address and including a first memory location at one end of the first non-volatile memory section and a last memory location at the opposite end thereof, a volatile memory section, and a storage controller operably connected to the first non-volatile memory section and the volatile memory section and adapted to: receive a plurality of data records including data records of at least two different category types, wherein each data record comprises a data value, an indication of the category type of the respective data record, and a time stamp including a time information, determine the category type of each received data record on the basis of the indication of the category type of the respective data record, sequentially store one by one the data records in the order they are received in the first non-volatile memory section by storing each data record into a memory location indicated by a write pointer that is maintained by the storage controller and that is incremented after each storage of a data record to indicate, in the direction from the first memory location towards the last memory location, the next memory location or, in case the last data record was stored into the last memory location, the first memory location, so that each memory location storing a data record stores exactly one data record, and for each received data record, add a new node associated with the received data record to a linked list that is stored in the volatile memory section for the determined category type of the received data record, such that upon storing all received data records there is a separate linked list stored in the volatile memory section for each category type included in the plurality of data records, wherein for each such linked list the nodes are only associated with data records of the same category type and the sequence of the nodes is such that the associated data records are temporally sorted according to their time stamp.
