Abstract: In the system design and development process, it is hoped the business logic is no longer a business

software system, a part of the application layer, separated from it. In this architecture means that, when

business logic changes, the system of non-business logic part of the design and coding do not need to

change. Clear separation of business logic and can be maintained by their own, and ready to existing

applications to call. This separation strategy greatly improved the system's adaptability and flexibility, but

also to system maintenance and upgrades bring great convenience. Wage system reform, making the payroll

system may change at the operational level, after the embedded rules engine can easily be achieved.

1 INTRODUCTION

In today's era of rapid development of information

technology, an endless stream of new information

technologies to promote the development of human

productive forces have made important contributions.

That is one of the rules engines, which allows

system design to better separate business needs,

changes in demand, not substantially change the

code, but can be successfully completed conversion.

Both government agencies or enterprises, wage

management system is required, it is the correct

release and pay personal income tax to provide a

convenient, but with our income, the gradual

improvement of tax policy, way of personal income

tax is also taking place certain changes. In order to

better respond to this change, this paper is to study

how to embed the system in the payroll rules engine,

which can more easily provide a guarantee for the

management of the daily wage.

2 BUSINESS RULE

MANAGEMENT SYSTEM

INTRODUCTION

In traditional application development and

implementation process, the Business Rules is

provided by the user requirements analysis phase,

embedded in the program code. Once the application

business rules will be developed and fixed is not

easy to change. However, filled in the application of

business rules in all aspects of the system and

corners, and often require frequent changes. As a

strategy for each application, the rule changes are

required developers to modify the source code,

limiting the application of system flexibility and

vitality. The Rules Engine after the introduction of

business rules separate from the code, business rules

in the form of program code no longer resides in the

system, instead of rules dealing with the rules engine.

Business rules reside in the rule base, the rule

changes is to use integrated development

environment for rules or the rules editor to modify

the rule base through the implementation. Business

rules are loaded into the rules engine for the supply

of system calls, so management must determine the

rules of the vitality of the system.

Business Rule Management System is a set of

tools, including: rules engine, rule base, rule

language framework, rule management integrated

development environment. The underlying rules

engine is the core, can be seen as an if-then the

senior interpreter. To use the business rules engine,

it has the following steps.

Firstly, we must establish rules in advance and

then deploy to an application rule instance. Then, the

rules are calculated, and the results before returning

to the user, may first be filtered. Finally, the user

used in the application code through the rules

dealing with the results. BRMS rule engine is the

core part. Rules are embedded in the code instead of

the part. Applications and business rules is a bridge,

responsible for the transmission of applications from

the application object and the transmission from the

rule base and rule set to match the success of the

implementation of the rules match the results output

to the application.

3 STRUCTURAL ANALYSIS

RULES ENGINE

Rule-based expert system appears to the developer

an opportunity to solve problems, this is the rules

engine. Rules engine by the expert system inference

engine from the development, which is an embedded

component in the application, the business

decision-making rules from the separation of

application code and the semantics of the module

using the predefined rules of writing business

decisions. To accept data entry, business rules

interpretation, and to make business decisions based

on business rules.

In today's enterprise software is more popular in

the rules engine and a variety of business process

management (BPM) system. Such tools are

committed to one thing: that a clear separation of

business logic, and by their own maintenance, and is

ready to invoke the existing application. Even

companies with information systems such as ERP,

business rules written into the program logic of most

of the code, coupled with application code. When

business needs change and when it can not respond

quickly make the appropriate changes, and try to

modify the existing code, and low efficiency, cost

significantly, thereby affecting the enterprise

information construction, and even the efficiency of

enterprises have also been Greatly affected.

Business Rules Engine rules must be explained

before you can run the business rules. Actually a

high performance rules engine can be viewed as a

special interpreter, including if-then operation of the

business object in business rules to run, and then

return to operating results and the modified business

objects. The world's leading business rules engine

products are basically commercial use the Rete

algorithm, and to support the deductive and

inductive.

By the rules, engine developed from the

rules-based system, knowledge base system is a

branch of artificial intelligence areas, which is

consists of three parts: Knowledge Base, Working

Memory and Inference Engine. Structure is as

follows:

Figure 1: Inference Engine.

Knowledge Management Knowledge Base for a

special kind of database so that the relevant domain

knowledge acquisition, consolidation, and extraction.

Knowledge in knowledge from experts in the field, it

is the domain knowledge to solve problems on the

set, including basic facts, rules and other relevant

information. Inference engine consists of three parts:

Rule Interprete, Pattern Matcher and Agenda.

Pattern matcher to perform from the Knowledge

Base to find out the rules and write the agenda;

agenda to give priority to these rules determine the

order of execution; rules interpreter to run the

implementation of these rules and the output results.

There are two inference engine reasoning, deductive

and inductive. Deduction rules applied by the facts

to a conclusion; induction is based on the

assumption that the definition, find the facts

consistent with the hypothesis. Using deductive

reasoning inference engine as follows:

(1) The initial data input to the work of memory;

(2) The device will use pattern matching rules in the

knowledge base and data comparison;

(3) If the enforcement of rules of conflict, which

also activates a number of rules, the rules of the

conflict into the conflict set;

(4) Resolution of the conflict, the rules will be

activated in sequence into the agenda;

(5) The implementation of the rules of the agenda;

(6) Repeat steps (2) to (5), until the completion of

the agenda of the implementation of all the rules, the

output operation results.

Business Rules execution order is based on the

implementation of the priority agenda to decide,

when the engine enforcing rules, as a result of the

memory data objects because of execution rules

changed so that the implementation of the agenda of

the business rules dynamic execution instances will

occur Changes that may increase may be reduced.

Thus a kind of "dynamic" rule execution chain, it is

forming the so-called rules of inference mechanism.

4 SALARY MANAGEMENT

SYSTEM BUSINESS

REQUIREMENTS

(1) Pay all persons within and outside the enterprise

payroll and other types of remuneration: the ability

to handle both the release of data from many

different sources, so that all who paid for the same

amount of tax can be merged; processed to generate

different documents issued by banks.

(2) Rule-based processing: for different types of

personnel have better adaptability; help add and

change a new tax processing logic.

(3) Can be modified on behalf of the

Development Services and format, used to connect

data from different customers.

(4) Based on exception handling: Exceptions and

errors can be defined priority transaction, the user

can put these exceptions into the pre-defined

components, and then you can follow up on these

exception errors handling.

(5) A high degree of reliability: in the generation

of hair system, each data is very important, so the

generation of hair loss or duplication of data systems

for the generation of fat is not allowed; This may

lead to inaccurate tax, which so that people pay

more or less appropriate to pay individual income

tax, resulting in a series of unnecessary trouble.

(6) A high degree of security: Obviously, the

security system is essential for the generation of fat.

The system is through encryption, authentication,

authorization and other, which means to protect the

security of the system.

(7) Browser-based user interface: to provide a

good Java-based HTML interface to the user in

order to achieve loosely coupled, easy operation and

maintenance of the system requirements.

The emergence of the rule engine is the

development of management information systems,

which has great benefits. Rule-based approach

reduces business requirements analysis, coding,

integration-testing and system deployment of links,

shorten the development cycle, more responsive to

changes in the system business logic. Developers

can use business rules without knowing too much

about the technical implementation details of the

system, reducing the workload of programming and

reduce the probability of programming errors, so

that developers pay more attention to business rules,

business requirements of the system itself rather than

specific programming technology. Business rule

language can be more natural language form, meet

the business rules used to prepare personnel to

improve the business rules of intelligibility and

maintainability.

For these purposes, while based on the

characteristics of its own payroll system to consider,

for the salary management system designed and

implemented a set of rules manager wage Salary

Rules Manager, referred to as the SRM.SRM and the

business layer closely integrated with the payroll

system for the business information provided

validation, expansion and translation services. SRM

core of the library includes business rules, rule

compiler, rule configuration manager, the rules

processor and reference data system interface.

Running the entire business rules with workflow

components are independent off. Workflow

components to run the business rules to issue

commands, FRM based on customer configuration

information, selected set of business rules to be

executed, run the business rules, if necessary, call

the reference data systems to obtain the relevant data,

the results of the final run back to the work flow

group pieces.
