Create Campaign
Technical Documentation: Create Campaign Flow
Overview
This document outlines the flow for creating a campaign using various services in the system. The process involves interactions between multiple services, including the Project Factory, Project Service, Boundary Service, Facility Service, HRMS Service, MDMS Service, FileStore Service, and the database. This flow ensures that the required resources are validated and correctly set up before finalizing the campaign creation.
Actors and Participants
Client: The entity (user or system) initiating the campaign creation request.
CampaignManager (Project Factory): The main controller managing the campaign creation process.
ProjectService: Manages project-related operations, including data creation and mapping.
BoundaryService: Handles fetching of boundary relationships based on hierarchy types.
FacilityService: Responsible for creating facility-related data.
HRMSService: Manages the creation of employee data.
MDMSService: Provides master data such as project types.
FileStoreService: Manages the storage and retrieval of resource files.
Database: Stores campaign-related data and status updates.
Sequence Flow
Initiate Campaign Creation
The Client sends a request to the CampaignManager to create a campaign with all required and valid resources.
Fetch Boundary Relationship
The CampaignManager requests the BoundaryService to fetch the boundary relationship based on the hierarchy type.
The BoundaryService responds with the relevant boundary relationship data.
Fetch Project Type Master
The CampaignManager requests the MDMSService to fetch the project type master data.
The MDMSService responds with the project type master.
Validate Resource Files
The CampaignManager checks the Database to see if the input resource files have already been validated.
The Database responds with the validation status of the files.
Validation Check
The CampaignManager checks if all file templates and data are validated:
If validation is successful, the CampaignManager informs the Client that the campaign creation process has started, and the user needs to track the status using an ID.
If validation fails, the CampaignManager returns an error message, indicating which validation failed, and the user must resubmit the request.
Resource File Retrieval
The CampaignManager interacts with the FileStoreService to search for the resource based on the
filestoreid.The FileStoreService responds with the valid resource files.
Process Resource Data
The CampaignManager processes the retrieved sheets and identifies any resource data that needs to be created.
Facility Data Creation
The CampaignManager sends a request to the FacilityService to create facility data.
The FacilityService responds that the facilities have been created successfully.
Employee Data Creation
The CampaignManager sends a request to the HRMSService to create employee data.
The HRMSService responds that the employees have been created successfully.
Project Data Creation
The CampaignManager sends a request to the ProjectService to create project data with a parent-child relationship based on the project type and delivery configuration.
The ProjectService responds that the projects have been created successfully.
Project-Facility Mapping Creation
The CampaignManager sends a request to the ProjectService to create mappings between projects and facilities.
The ProjectService responds that the project-facility mappings have been created successfully.
Project-Staff Mapping Creation
The CampaignManager sends a request to the ProjectService to create mappings between projects and staff.
The ProjectService responds that the project-staff mappings have been created successfully.
Update Campaign Creation Status
The CampaignManager updates the Database with the status of the campaign creation process.
Error Handling
Validation Failure: If any validation step fails (e.g., invalid data in resource files), the CampaignManager sends an error message to the Client, indicating the failure. The user is required to fix the issues and resubmit the request.
Service Errors: If any of the service interactions (e.g., BoundaryService, MDMSService) return an error, the CampaignManager stops the process and informs the Client of the failure, specifying the nature of the error.
Database Errors: If the Database fails to update the campaign creation status, appropriate error handling and logging mechanisms should be triggered to handle the failure.

Conclusion
This document provides an overview of the create campaign flow, detailing each step and interaction between different services and the database. The flow ensures proper validation and creation of necessary resources, while error handling mechanisms provide robustness to the process.
