Abstract

Data management apparatus, method, and non-transitory tangible machine-readable medium thereof are provided. A memory space of an in-memory database is allocated for a sliding table, wherein the sliding table includes a plurality of records stored in a sequential order according to a time stamp of each record. A first head pointer points to the beginning address of the least recent record among the records, while a tail pointer points to the following address of the most recent record among the records. When at least one new record comprising a time stamp is inserted into the sliding table, the tail pointer will be updated. When at least one expired record of the sliding table is identified according to a preset time bound and the time stamp of each expired record, the head point will be updated.

Dependent claims

A data management apparatus, comprising:

an in-memory database, wherein a first memory space of the in-memory database is allocated for a first sliding table, the first sliding table comprises a plurality of records stored in a sequential order according to a time stamp of each record, a first head pointer points to a beginning address of a least recent record among the records and a first tail pointer points to a following address of a most recent record among the records;
and
a processor, being electrically connected to the in-memory database and configured to insert at least one new record comprising a time stamp into the first sliding table according to the first tail pointer, move the first tail pointer according to a number of the at least one new record,
wherein the processor is further configured to identify at least one expired record in the first sliding table according to a preset time bound and the time stamp of each expired record and move the first head pointer according to a number of the at least one expired record.

1 more element

A non-transitory tangible machine-readable medium, being stored with a computer program, the computer program comprising a plurality of codes, the codes being able to execute a data management method when the computer program is loaded into an electronic apparatus, a first memory space of an in-memory database being allocated for a first sliding table, the first sliding table comprising a plurality of records stored in a sequential order according to a time stamp of each record, a first head pointer pointing to a beginning address of a least recent record among the records, a first tail pointer pointing to a following address of a most recent record among the records, and the data management method comprising the steps of:

(a) inserting at least one new record comprising a time stamp into the first sliding table according to the first tail pointer;
(b) moving the first tail pointer according to a number of the at least one new record;
(c) identifying at least one expired record in the first sliding table according to a preset time bound and the time stamp of each expired record;
and
(d) moving the first head pointer according to a number of the at least one expired record.
