When User data occur change into data reduce time, determine that first of this minimizing changes data by comparison active user viewdata and upper User data, and do not existed in User data due to the first data of this minimizing, therefore, in User data, the first numerical value changing data of this minimizing is zero, therefore, according to the data dependence relation had between User data and data model data, find in data model data with this first change data-dependent rely first rely on data after, first numerical value relying on data in data model is revised as the numerical value of these the first change data, namely be that the first numerical value relying on data in this data model is revised as zero, namely be equivalent to by from this data model, these the first dependence data be left out, thus ensure that User data and data model data are consistent.
When User data occur change into data change time, then determine that first of this change changes data by comparison active user viewdata and upper User data, and according to the data dependence relation had between User data and data model data, find in data model data with this first change that data-dependent relies first rely on data, directly this first numerical value relying on data is revised as the numerical value of these the first change data, ensures that User data and data model data are consistent.
Optionally, due to the numerical value successfully numerical value that first relies on data being revised as the first change data surely that differs, therefore, after the numerical value that first relies on data is revised as the numerical operation of the first change data by execution, whether the data model data after can also modifying with the numerical value relying on data to first by judging these User data changed are identical, judge whether the numerical value successfully numerical value that first relies on data being revised as the first change data.
If the data model data after judging these User data changed and modifying to the numerical value of the first dependence data are different, then illustrating fails is revised as the numerical value of the first change data by the numerical value that first relies on data, otherwise, if the data model data after judging these User data changed and modifying to the numerical value of the first dependence data are identical, then the numerical value successfully numerical value that first relies on data being revised as the first change data is described.
Optionally, if the data model data after judging these User data changed and modifying to the numerical value of the first dependence data are different, fail and the numerical value that first relies on data is revised as the numerical value of the first change data, then again can will perform and rely on first the operation that the numerical value of data is revised as the numerical value of the first change data, until judge the User data changed modify with the numerical value relying on data to first after data model data identical.
Optionally, can after the numerical value that first relies on data be revised as the numerical operation of the first change data by execution, accumulative amendment first of starting from scratch relies on the number of times of the numerical value of data, obtain first number, if rely on the amendment number of times of data to first, namely the numerical value of first number is greater than predetermined threshold value, then can think that this first dependence data modification is failed, generate the first error message, by this first number zero.
Step S130: judge whether that monitoring described data model data changes; If monitor, then enter step S140, if do not monitor, then enter step S150;
Step S140: determine that the second change data and described second changed in the data model data changed change the numerical value of data, and according to described data dependence relation search in described User data to change with described second that data-dependent relies second relies on data, the numerical value that described second relies on data is revised as the numerical value of described second change data;
If monitor data model data to change, then by determining the numerical value of the first change data and these the first change data changed in these data model data, according to the data dependence relation had between data model data and data model data search in data model data with this first change that data-dependent relies first rely on data, this first numerical value relying on data is revised as the numerical value of these the first change data, data model data are revised accordingly, data model data and data model data are consistent.
