[[File:Widp.png|left|110px]]WHO Integrated Data Platform (WIDP) is a graphical web-based health management information system (HMIS) used at WHO for regular data reporting, as well as for empowering countries for local routine surveillance and monitoring. WIDP is built on top of [https://www.dhis2.org/ District Health Information Software 2 (DHIS2)], an open source, web-based HMIS platform, already in use by Ministries of Health, research centers, NGOs and other parties in more than 100 countries around the world. WIDP supports data collection as well as data analysis and visualization.



=== WIDP Data model ===
The most important feature of WIDP is the data model it uses for capturing data. 

WIDP distinguishes two main types of data: 
* '''Individual''': Data about individual cases or events, occurred in a specific point in time. Respectively, these data can be identifiable (Trackers, e.g., patient records) or non-identifiable (Events, e.g., Dwelling inspections/interventions).
* '''Aggregated''' (Collective): Data summarized over a specified period of time (daily, weekly, monthly, quarterly, yearly, etc.) and for a specific geographical area.

Data inside WIDP can be collected and analyzed through various [https://docs.dhis2.org/master/en/user/html/dhis2_user_manual_en_full.html#d1478e41894 dimensions].

* '''What?''' - main information of interest (e.g., Number of infection cases, Result of serological diagnosis).    [https://www.dhis2.org/ DHIS2] implements it through ''[https://docs.dhis2.org/master/en/end-user/html/dhis2_end_user_manual_full.html#data-elements data elements].''
* '''Where?''' - geographical location to which the information relates to (e.g., Region/City of infection cases, Health facility where the serological diagnosis is done).  [https://www.dhis2.org/ DHIS2] implements it through [https://docs.dhis2.org/master/en/end-user/html/dhis2_end_user_manual_full.html#the-organisational-hierarchy organisation unit hierarchy].
* '''When?''' - Date or period to which the information  relates to (e.g., Period for which the infection cases are calculated, Date of the serological tests).  [https://www.dhis2.org/ DHIS2] implements it through different types of ''[https://docs.dhis2.org/master/en/user/html/dhis2_user_manual_en_full.html#period_types periods]''.
* '''Other''' customizable set of dimensions (e.g., pharmaceutical companies dispatching the medicine). [https://www.dhis2.org/ DHIS2] implements them through ''[https://docs.dhis2.org/master/en/user/html/dhis2_user_manual_en_full.html#additional_data_dimensions attribute categories]''.

=== Data entry in WIDP ===
Depending on the type of data, WIDP offers three core apps for [https://en.wikipedia.org/wiki/Form_(document) form]-based data entry: 
* '''Aggregated data''': ''[https://docs.dhis2.org/master/en/user/html/dhis2_user_manual_en_full.html#data_entry_app Data Entry]'' 
* '''Individual non-identifiable data''':''[https://docs.dhis2.org/master/en/user/html/dhis2_user_manual_en_full.html#event_capture_app Event Capture]'' 
* '''Individual identifiable data''': ''[https://docs.dhis2.org/master/en/user/html/dhis2_user_manual_en_full.html#tracker_capture_app Tracker Capture]''

In addition, WIDP also allows you to enter data in a massive (bulk) mode using Excel spreadsheets though [[Bulk load app]].

=== Data analysis and visualization in WIDP ===

Starting from data entered into the system, WIDP also allows automatic calculation of [https://docs.dhis2.org/master/en/end-user/html/database_design.html#indicators indicators] by combining information from one or more data collection forms, and their constant monitoring through dashboards.  

WIDP provides support for analyzing and visualizing previously collected data inside dashboards, namely through three main data visualization elements: [[File:Widp-dashboards.png|500px|thumb|right|Data analysis and visualization in WIDP]]

* ''[https://docs.dhis2.org/master/en/user/html/dhis2_user_manual_en_full.html#data_vis '''Charts''']''
* ''[https://docs.dhis2.org/master/en/user/html/dhis2_user_manual_en_full.html#using_maps '''Maps''']'' 
* ''[https://docs.dhis2.org/master/en/user/html/dhis2_user_manual_en_full.html#pivot '''Tables''']''

To help more collaborative analysis of data DHIS2 allows entering textual interpretations of dashboard elements, comments and discussions. See more information about  [https://docs.dhis2.org/master/en/user/html/dhis2_user_manual_en_full.html#dashboard managing dashboards in WIDP].
