Request and Response Execution Flow of Queries

Request and Response of Query Execution Flow is discussed

What Components are involved in Query Execution Flow

What Data Passing Data Structures are involved in Query Execution Flow

We selected the Data Access Pattern, by seeing how FAT the Domain Scenario/Feature is. Request Processing Pipeline for different scenarios.

Command is executed in two steps
Request Query
Response Query

Query Execution Flow

Flow of Request Fetch operation without business logic, while showing data on the Form

View è Controller è Query AS è Data Access Class è EF Repository è DB

Passing Data Strcutures for above Operation:  

QueryRequestViewModel/PrimiteDataType/ è QueryRequestModel/PrimiteDataType/ è Entities/VO/TrueFalse/PrimiteDataType/CustomeDataStructure

For executing Domain Logic in Domain Model, 

before Fetching Data from DB

Query AS è Factories/Domain Services/Entities/VO/Aggregates Roots/ Domain Events

Passing Data Strcutures for above Operation: 
Entities/VO

Response of Domain Logic execution, 

before Fetching Data from DB

Query AS ç Factories/Domain Services/Entities/VO/Aggregates Roots/ Domain Events

Passing Data Strcutures for above Operation: 
Entities/VO/TrueFalse/PrimiteDataType/CustomeDataStructure

Showing the response of Query Operation on the UI

View ç Controller ç AS ç Data Access Class ç EF Repository ç DB

Passing Data Strcutures for above Operation: 

   GenericQueryResponseModel ç GenericQueryResponseModel ç Entities/VO/TrueFalse/PrimiteDataType/CustomeDataStructure
