Abstract

The invention relates to a data management method and device, computer equipment and a storage medium. The method comprises the following steps: establishing a storage array, and establishing an effective record linked list and an invalid record linked list according to the storage array; detecting a record block in the storage array; if the record block in the storage array is an effective recordblock, pointing the effective record linked list to the effective record block; and if the record block in the storage array is an invalid record block, pointing the invalid record linked list to theinvalid record block. Through adoption of the method, record blocks in the storage array can be orderly managed by establishing the effective record linked list and the invalid record linked list, and subsequent access does not need to traverse the effective record linked list and the invalid record linked list.

Description

technical field [0001] The present application relates to the technical field of databases, and in particular, to a data management method, apparatus, computer equipment and storage medium. Background technique [0002] With the development of database technology, data management technology has emerged. In related technologies, arrays or linked lists are commonly used to store data. The so-called array is an ordered sequence of elements, which is used to store multiple sets of data of the same type. The so-called linked list is a non-consecutive, non-sequential storage structure on a physical storage unit. However, the access efficiency of the data structure of the array or linked list is not high, and the disadvantage of the linked list is that it does not support random reading, and the reading efficiency is low. Although the array supports random reading, the space utilization is not flexible enough. Moreover, in the case of multi-level nested traversal, the reading eff...
