此模型将复杂的嵌套关系模式分解为由主键或主键和一个非主属性构成的原子模式集合。

This model decomposes a nested relational schema into a set of atomic schemas, each of them constitutes of a primary key or a primary key plus a non-primary attribute.

给出了自体、非自体的动态演化模型，解决的自体、非自体的动态描述问题，有效地降低了自体集合的大小。

The problem of dynamic evolution of self and nonself are solved which reduces the size of self universe effectively.
