## Flogo Rules based Creditcard application
2+
3+
4+
This example demonstrates rule based processing of credit card application. In this example three tuples are used, tuples description is given below.
5+
6+
7+
* `UserAccount` tuple is always stored in network, while the other tuples `NewAccount` and `UpdateCreditScore` are removed after usage as ttl is given as 0.
8+
9+
10+
## Usage
11+
12+
Get the repo and in this example main.go, functions.go both are available. We can directly build and run the app or create flogo rule app and run it.
13+
14+

15+
16+
```
17+
cBadUser : Check for new user input data - check if age <18 and >=45, empty address and salary less than 10k
18+
cNewUser : Check for new user input data - check if age >=18 and <= 44, address and salary >= 10k
19+
cUserIdMatch : Check for id match from 'UserAccount' and 'UpdateCreditScore' tuples
20+
cUserCreditScore : Check for CreditScore >= 750 && < 820
21+
cUserLowCreditScore : Check for CreditScore < 750
22+
cUserHighCreditScore : Check for CreditScore >= 820 && <= 900
23+
```
24+
#### Actions
25+
```
26+
aBadUser : Executes when age - < 18 and >=45, address empty, salary less than 10k
27+
aNewUser : Add the newuser info to userAccount tuple
28+
aApproveWithLowerLimit : Provides credit card application status approved with lower credit limit
29+
aApproveWithHigherLimit : Provides credit card application status approved with higher credit limit
30+
aUserReject : Rejects when lower Credit score provided and retracts NewAccount
31+
```
32+
