An algorithm for Electronic Commerce order match based on cross link-list index structure was designed which can achieve faster and more effective searching goods as well as trade orders matches.

Data storage of multi-rigid-body system based on orthogonal list;

This article proposes one relational storage model notated with orthogonal list to construct topology structure abstracted among warehouse oriented power supply industry.

According to the data characteristic of the rough relational database,this paper solves the problem of uncertainty data storage with adjacency list and orthogonal list,and the adjacency list is for the equivalence classes storage and the orthogonal list for the basic table storage.

Methods To realize the above aim, program developing language C++, cross list data storage structure, the special method of pivoting and elimination of pivot element were adopted.

Based on the analysis of Apriori algorithm from the perspectives of time complexity and memory complexity, we use an across linker to substitute the array description of the transactions database.

A new image sign expression based on across linker is proposed in this paper which includes expressions and descriptions of area and boundary.

The authors employ element index, attribute index and structure index to record the XML document structure so as to excel the XML expressing capability.

In order to establish efficient access path, the authors put forward a structure index for XML data, and introduce a method of implementing operations based on.

This paper introduces the research situations on MarcXchange document and discusses deeply the structure index techniques based on MarcXchange document,which includes the logical structure,schema analysis,structure index framework,index algorithm,updates for structure index.
