Company Microservice

This microservice handles the creation, management, and querying of company data. It includes a Go data model for persistence and a Protocol Buffers definition for gRPC-based operations.

Company Model (company.go)

The Company struct defines the data structure for a company record:

Field	Type	Description
ID	uint32	Unique identifier for the company (auto-incremented)
Name	string	Company name (minimum 2 characters required)
Owner	uint32	ID of the company owner (required)
OrgID	uint32	Organization ID the company is linked to (required)
Logo	string	URL or path to the company logo
Slug	string	Unique slug/identifier for the company
PAN	string	Permanent Account Number (must be unique)
Address	string	Company address (text format)
IsActive	bool	Status indicating if the company is active
CreatedAt	time.Time	Timestamp when the record was created
UpdatedAt	time.Time	Timestamp when the record was last updated
CreatedBy	uint32	ID of the user who created the record
UpdatedBy	uint32	ID of the user who last updated the record

gRPC Service (company.proto)

The Protocol Buffers file defines the service interface and messages used for communication.

Messages

• Company: Reflects the fields of the Go Company model.
• CompanyId: Request message containing a company ID.
• CompanyList: Response with a list of Company objects.
• CompanyRequest: Used to create or update a company.
• CompanyResponse: Contains a single Company object in response.
• Empty: Used when no input or output is required.

Services

• CreateCompany(CompanyRequest) returns (CompanyResponse)
• GetCompany(CompanyId) returns (CompanyResponse)
• ListCompanies(Empty) returns (CompanyList)
• UpdateCompany(CompanyRequest) returns (CompanyResponse)
• DeleteCompany(CompanyId) returns (Empty)

These gRPC endpoints support standard CRUD operations for managing company records.
