Hi all,

DHIS 2 version 2.12 is released. We have some great new features for you:


- All analysis tools are working against the analytics Web API. This means
that the system is no longer dependent on the resource-demanding data mart
process and running it is now optional. You can still run data mart and use
it for custom reports but all analysis tools now read from the analytics
tables. These tables can be generated ad-hoc from reports module and
scheduled in data administration module. The analytics API allows you to do
a lot more flexible dimensional data analysis, for instance like this:

http://apps.dhis2.org/demo/dhis-web-pivot/app/index.html?id=otVrkxLmBJT


- In data visualizer module you can now do analysis on all fixed and
dynamic data dimensions. You can select any data dimension and items from
the left menu. You can also use multiple dimensions as filter. In DHIS 2
you can create dynamic data dimensions through data element group sets, org
unit group sets and categories. For instance we can now create interesting
charts where you compare immunization doses given at facility (fixed) and
outreach:

(Log in with admin/district)

http://apps.dhis2.org/demo/dhis-web-visualizer/app/index.html?id=LRFDsb8jcG0

You can make a chart comparing ANC visits for each facility type:

A chart showing HIV testing broken down on gender:

http://apps.dhis2.org/demo/dhis-web-visualizer/app/index.html?id=mKjgsRMJt0H

You can also include data element details (category option combos) directly
under data elements by selecting "Details" as opposed to "Totals" in the
drop down next to the list of data elements:

- In pivot table module we have added support for analysis on category
based dimensions - you can now do analysis based on all fixed and dynamic
data dimensions. All dimensions can be selected from the menu on the left.
You can for instance create a pivot table for vaccine doses given broken
down on age group and facility location like this:

http://apps.dhis2.org/demo/dhis-web-pivot/app/index.html?id=JsmBGbmRlEu


- In pivot table module you can now download your pivot table to your local
computer in Microsoft Excel, CSV and HTML format. The downloaded file will
have the same table layout as you see on the web page. As an example, load
a pivot table by clicking on the link below, then click on "Download" on
the top menu, then "Microsoft Excel" under "Table layout".

http://apps.dhis2.org/demo/dhis-web-visualizer/app/index.html?id=otVrkxLmBJT

You can also use the pivot table to browse the analytics web api and use
the download options under "Plain data source" to retrieve the data
response.


- Pivot table now supports data interpretations. Load a favorite, click on
"Share" in the top menu and write your question, comment or interpretation.
It will become visible in the data interpretation feed in the dashboard.

- In GIS you can now include data element details (category option combos)
in a map. For instance you can create a map for ANC 1st visits at facility
(fixed) like this:

http://apps.dhis2.org/demo/dhis-web-mapping/app/index.html?id=YOEGBvxjAY0


- Single events without registration (anonymous events) are now supported
in the Web API. This means that you can send event data from case-based
systems like EMRs directly to DHIS 2, and create mobile clients for event
registrations which send event data over HTTP to DHIS 2. Documentation here:

http://dhis2.org/doc/snapshot/en/user/html/ch25s07.html


- Data entry for single events without registration now works offline, in
the same way as the routine data entry. This implies that you can log onto
DHIS 2 in the morning and continue with data entry throughout the day even
if Internet connectivity is lost or intermittent. Even large option sets
for ICD 10 codes work offline, and performance is improved in general.
Check it out here:

http://apps.dhis2.org/demo/dhis-web-caseentry/anonymousRegistration.action


- In tracker you can now define program indicators, creating formulas based
on person data elements in order to make more useful analysis:

http://apps.dhis2.org/demo/dhis-web-maintenance-patient/program.action


- In tracker we have a new analysis function which gives completeness for
each program and its program stages:

http://apps.dhis2.org/demo/dhis-web-caseentry/programStageCompletenessSelect.action


- Option sets and data elements of type yes-only are now supported in the
routine data entry module. This will be useful for several use-cases, for
instance when making facility assessment forms. We recommend sticking with
numeric option sets and data elements in routine data entry since text
cannot be aggregated. Check it out by selecting the "Facility assessment"
form here:

http://apps.dhis2.org/demo/dhis-web-dataentry/index.action


- Data set report and reporting rate summary now allows you to use all
organisation unit group based dimensions as filters. For instance you can
filter your data set report to only include data for a certain facility
type. Click on "More options" to select the filters in data set report:

http://apps.dhis2.org/demo/dhis-web-reporting/showDataSetReportForm

Same goes for reporting rate summary:

http://apps.dhis2.org/demo/dhis-web-reporting/displayViewDataCompletenessForm.action


- Data entry can now be done through PDF files. This implies that data
entry can be done completely offline and detached from DHIS 2 through the
well-understood PDF format. You can download PDF form templates from the
data set module by clicking on the PDF icon. Forms can later be uploaded
through the import-export module by going to "PDF Data Import". This allows
for workflows where forms are distributed to remote / mostly disconnected
areas, filled and returned by email before uploaded to the central instance.

- Support for "app" extensions. You can now develop stand-alone apps and
use them as extensions to DHIS 2. The apps should be based on javascript
and HTML and use the DHIS Web API for retrieving data. The apps must be
packaged according to the W3 manifest for Web applications. You can upload
the apps in the Apps service module. Documentation here:

http://dhis2.org/doc/snapshot/en/user/html/ch27.html

You can see the admin module here:

http://apps.dhis2.org/demo/dhis-web-appmanager/appList.action


- The analytics Web API resource now supports data responses with table
layout. This means that you can generate ready-made tabular reports in
Excel, CSV or HTML format straight from the analytics API using dynamic
input parameters without defining anything up front. This is an example
Excel report generated on the fly by using the tableLayout, columns and
rows query parameters:

http://apps.dhis2.org/demo/api/analytics.xls?dimension=dx:fbfJHSPpUQD;cYeuwXTCPkU&dimension=pe:LAST_12_MONTHS&dimension=ou:LEVEL-3-O6uvpzGd5pu&tableLayout=true&columns=dx;pe&rows=ou

You can read the documentation here:

You can download the 2.12 release here:

The new analytics engine requires that more of your server resources are
dedicated towards the database in favor of the Java VM. It also requires
that you have a fast disk type. We will provide more info about this
shortly.


For this release we had source code contributions from PSI and Critical
software - much appreciated. Also thanks to all developers who have worked
very hard to finalize all this in only two months.

Enjoy the new version. Feedback is appreciated.


best regards,


the DHIS 2 development team
