Data Model Detection Module

Source: R/mod_data_model_detection.R
mod_data_model_detection.Rd

This module will interrogate a user connected database, comparing it with known common data models to determine the both the data model and version (when applicable) of the user's database.

It informs the rest of the application how to interpret and display the data stored in the connected database, when possible. If an unsupported data model is detected, the user is informed and given the opportunity to connect to a different database.

This module consists of the following components:

Module UI functions

These functions return a Shiny tagList containing various UI elements of the ReviewR application. UI components are calculated by the data_model_detection_server function of this module.

  • data_model_detection_ui: A server defined uiOutput describing the detected data model and version.

  • patient_chart_ui: The "Patient Chart," with the appropriate display elements based on the detected data model. Appears on the "Chart Review" tab of ReviewR.

Module Server function

The server function of this module is responsible for calculating the display elements included in the UI functions of this module as well as returning a reactiveValues object containing various other objects used by other modules.

  • data_model_detection_server: Contains the data model detection logic and calculates UI elements. Returns a reactiveValues object containing variables used in other modules.

Usage

data_model_detection_ui(id)

patient_chart_ui(id)

data_model_detection_server(id, database_vars, navigation_vars, parent_session)

Arguments

id

The Module namespace

database_vars

A reactiveValues object as returned by mod_database_setup.

navigation_vars

A reactiveValues object as returned by mod_navigation.

parent_session

The session information from the parent environment of this module.

Value

data_model_detection_ui:

tagList

A uiOutput describing the detected data model and version.

patient_chart_ui:

tagList

The "Patient Chart" on the "Chart Review" tab of ReviewR.

data_model_detection_server:

reactiveValues

  • table_map: A tibble containing a mapping between the CDM standard tables and fields to the user connected tables and fields.

  • message: A character vector containing the message describing the detected data model and version.

  • table_functions: A tibble containing the table function names for the detected data model as well as the table names which the functions will create.

  • all_patients_table: A tibble containing only the "All Patients" function and table name. Used to render the "All Patients" table on the "Patient Search" tab.

  • subject_tables: A tibble containing the "Subject Specific" functions and table names. Used to render the patient chart tabsets on the "Chart Review" tab.
