Abstract

A data management apparatus, method, and computer program product thereof arc provided. The data management apparatus reads a recursively structured data and stores the recursively structured data ina one-dimensional memory space. The recursively structured data has a Location Independent Structure (LIS) in the one-dimensional memory space and is extendible and growable. The recursively structured data has a plurality of data elements and a plurality of sub-LISs, the data elements correspond to the sub-LISs one-to-one, each of the data elements has a first index number, and each of the sub-LISs has a second index number. The data management apparatus stores the data elements in the one-dimensional memory space contiguously by following a descendent order of the first index numbers, storesthe sub-LISs in the one-dimensional memory space contiguously by following an ascendant order of the second index numbers, and the sub-LISs arc stored right behind the data elements.

Description

technical field [0001] The invention relates to a data management device, method and computer storage medium thereof. Specifically, the present invention relates to a data management device, method and computer storage medium for recursively structured data. Background technique [0002] Due to the limited physical memory space of electronic computing devices (such as servers and personal computers), current operating systems often use virtual memory and demand paging technology to manage running applications The memory space required by the program. When an application program is running, if the code or / and data required by it has not been loaded into the physical memory, a page fault will occur. When a page fault occurs, the operating system will determine whether the access that caused the page fault is legal. If the access that caused the page fault is legitimate, the operating system will attempt to load the required paging data from virtual memory on the hard disk i...
