Claims

Receiving at the computer system one or more updates of data stored in the computer system;
Updating one or more multi-time data items in the computer system based on the received update;
Identifying the first query in the computer system based on a determination that the first query is dependent on the updated multi-time data item;
Performing a first execution of the first query using multi-time data corresponding to a current time;
Performing second execution of the first query using multi-time data corresponding to past time corresponding to past execution of the first query;
Determining a difference between a result of the first execution of the first query and a result of the second execution of the first query;
Comparing the difference with a predetermined threshold;
Invoking a first transformation process on a first data object associated with the first query when it is determined that the difference is greater than the predetermined threshold.

The method of claim 1, wherein the first transformation process is performed by a data transformation loop application that is executed within a compute node of a HADOOP data processing cluster.

The first transformation processing includes machine learning process, raw data processing classification, support vector machine, naive Bayes classifier, neural network, clustering, related rules, decision tree, univariate periodic linear trend, multivariate state estimation technology, cognition Computing, Bayesian belief networks, least squares optimization or regression of solutions to inverse problems, impact diagrams, Dempster-Shafer theory, decision trees, remaining useful life prognosis, scripts, plans, schedules, BPEL workflows, and BPMN business processes The method of claim 2, comprising one or more of:

Storing a second data object corresponding to a result of the first conversion process on the first data object;
Determining a difference between the second data object and a different data object of the same type as the second data object generated by a previous call of the first conversion process;
Calling a second transformation process on the second data object based on a determination that the difference between the second data object and the different data object is greater than a second predetermined threshold; The method of claim 1.

The first conversion process and the second conversion process are part of a continuous data conversion loop application;
The method
Receiving one or more additional updates of the multi-time data stored in the computer system;
Updating a set of multi-time data items based on the received additional updates;
Performing a third execution of the first query using the additional update of the multi-time data;
Performing a fourth execution of the first query using multi-time data corresponding to a past execution time of the first query;
Determining a difference between a result of the third execution of the first query and a result of the fourth execution of the first query;
Comparing the difference to the predetermined threshold;
The method according to claim 4, further comprising a step of re-invoking the first conversion process when it is determined that the difference is larger than the predetermined threshold value.

The updated one or more multi-time data item has been is a bi-time data item including the transaction time and valid time for each data item, the method according to any one of claims 1-5.

Identifying the first query includes accessing a filter table in the computer system;
The filter table comprises a plurality of queries that correspond to the different conversion method according to any one of claims 1 to 6 in.

Identifying the first query, performing a first execution of the first query, performing a second execution of the first query, the first execution of the first query, and the first query. Comparing the difference between the second execution of the first and second executions with the predetermined threshold is performed asynchronously with the first transaction outside the first transaction as an update of the one or more multi-time data items. ,
Wherein for the first data object the call to the first conversion process, the first transaction is outside executed the first transaction and asynchronously of method according to any one of claims 1-7.

A processing unit including one or more processors;
A memory coupled to the processing unit, readable by the processing unit, and storing a series of instruction sets, wherein when the instructions are executed by the processing unit, the processing unit includes the following steps: That is,
Receiving one or more updates of data stored in the computer system;
Updating one or more multi-time data items in the computer system based on the received update;
Identifying the first query in the computer system based on a determination that the first query is dependent on the updated multi-time data item;
Performing a first execution of the first query using multi-time data corresponding to a current time;
Performing second execution of the first query using multi-time data corresponding to past time corresponding to past execution of the first query;
Determining a difference between a result of the first execution of the first query and a result of the second execution of the first query;
Comparing the difference with a predetermined threshold;
And a step of calling a first conversion process on a first data object related to the first query when it is determined that the difference is greater than the predetermined threshold.

A program for causing a computer to execute the method according to claim 1.

A memory storing the program according to claim 10;
And a processor for executing the program.
