A DATA MANAGEMENT SYSTEM AND METHOD

摘要

The present invention relates to a data management system and method for storing a plurality of data records (10) including data records of at least two different category types in a non-volatile memory section (12) divided into a plurality of sequentially arranged memory locations. By means of a storage controller (228), the data records (10), each comprising an indication (20) of its category type and a time stamp (21), are sequentially stored one by one in the order of receipt into memory locations indicated by a cyclic write pointer (26) that is incremented following storage of each data record (10) such that each memory location storing a data record stores exactly one data, record (10). For each data record (10) its category type is determined based on its category type indication (20), and a new node (34) associated with the data record (10) is added to a linked list that is stored in a volatile memory section (32) for the determined category type of the data record (10), such that upon storing all received data records (10) there is a separate linked list stored in the volatile memory section (32) for each category type included in the plurality of data records (10), wherein for each such linked list the nodes (34) are only associated with data records (10) of the same category type and the sequence of the nodes (34) is such that the associated data records (10) are temporally sorted according to their time stamp.
