We observe that many spatio-temporal trees patterns are both unordered and embedded. Unordered refers to the condition that the sequence between children of the same parent is not important (for example, the tree with bedroom1 as the left son and bedroom2 as the right son is the same as the tree with bedroom2 as the left son and bedroom 1 as the right son) while embedded suggests that it is not necessary to strictly keep the parent-child relations among nodes.

An effective analysis of the battlefield situation and spatio-temporal data model in a sea battlefield has great significance for the commander to perceive the battlefield situation and to make the right decisions. Based on the existing spatio-temporal data model, the present paper gives a comprehensive analysis of the characteristics of sea battlefield data, and chooses the object-oriented spatio-temporal data model to modify it; at the same time this paper introduces sea battlefield space-time algebra system to define various data types formally, which lays the foundation for the establishment of the sea battlefield spatio-temporal data model.
