Zusammenfassung:The invention discloses an embedded active memory object database design method, which is characterized in that: (1) a mode for describing an object model realizes seamless combination of object data and relational data in the process of mapping the object model and a relational model, avoids the calculation process for the object-relation mapping process and improves the access speed for a memory object database by directly mapping multi-dimensional object relationships into three special two-dimensional tables; (2) a data organization mode of taking an object attribute column as a basic structure optimizes the database reading speed; (3) a quick loading mechanism shortens system starting time and improves system availability; and (4) an active object information notification mode changes the traditional strong coupling design of 'data structure + algorithm', and simplifies a function application developing step.
