Claims (10)
1. A data processing method based on a declarative and distributed ledgers is characterized by comprising the following steps:
the declarative programming model converts the upper-layer business to-be-consensus business logic into a first declarative statement according to a preset specification;
the engine service firstly calls an analysis interpreter to analyze the first declarative statement, then calls an execution controller to judge whether the analysis result meets a preset execution condition, and if so, constructs an execution tree to generate an execution plan and executes the execution plan;

3. The method of claim 1, wherein after the declarative programming model converts the upper-layer business to-be-commonly-recognized business logic into a first declarative statement according to a preset specification, the engine service calls the analysis interpreter to analyze the first declarative statement, then calls the execution controller to determine whether an analysis result meets a preset execution condition, and if so, constructs an execution tree to generate an execution plan and further comprises:
a connector passes the first declarative statement into a configured engine service.
4. The method of claim 2, wherein after the declarative programming model converts the upper-layer business to-be-queried business logic into a second declarative statement according to the preset specification, the engine service invokes the analysis interpreter to analyze the second declarative statement, and invokes the response controller to respond to the analysis result according to the preset response rule, and the constructing the execution tree according to the response result to generate the execution plan further comprises:
a connector passes the second declarative statement into a configured engine service.
5. The method of claim 1, wherein the execution controller generates the execution condition by receiving a first configuration content of a user.
6. The method of claim 2, wherein the response controller generates the response rule by receiving a second configuration content of the user.
7. The method of claim 1, wherein the transaction processor supports simultaneous configuration of multiple distributed coherency networks.
8. A data processing apparatus based on a declarative and distributed ledger, comprising:
the declarative programming model is used for converting the upper-layer business to-be-consensus business logic into a first declarative statement according to a preset specification;
the engine service is used for calling an analysis interpreter to analyze the first declarative statement, then calling an execution controller to judge whether an analysis result meets a preset execution condition, and if so, constructing an execution tree to generate an execution plan and execute the execution plan;
and the transaction executor is used for converting the execution result into transaction data and writing the transaction data into the distributed consistency network for consensus processing.
9. The apparatus of claim 8,
the declarative programming model is also used for converting the business logic to be inquired of the upper layer business into a second declarative statement according to a preset specification;
the engine service is also used for calling the analysis interpreter to analyze the second declarative statement, calling the response controller to respond the analysis result according to the preset response rule, and constructing an execution tree according to the response result to generate and execute an execution plan;
further comprising: the business inquiry device is used for inquiring the business,
and the transaction querier is used for determining a result value and a state value in the distributed consistency network according to the execution result and returning the result value and the state value to the upper-layer service.
10. An electronic device, comprising: memory and a processor, characterized in that the memory has stored therein a computer program, wherein the processor is arranged to run the computer program to execute the method of data processing based on declarative and distributed ledgers of any one of claims 1 to 7.
