Hi all,
DHIS version 2.19 is out. We have some great new features for you.
DATA ANALYSIS FEATURES----
Data ranges in event analysis: In event reports and visualizer you can define
and display numeric values in ranges. This is useful e.g. for age, weight and
scores where aggregate values can be presented in ranges such as “1-5”, “5-10”
as opposed to by discrete numbers. The ranges are based on legend sets (must be
created in GIS for now). You can enable ranges from a drop-down next to each
data item in the left panel.

Plain tables in event reports: In event reports you can display the items from
multiple data elements and attributes as a single dimension. Normally each data
element is displayed a separate dimension. You can enable this from “Layout” >
“Collapse data dimensions”. This allows you e.g. to create large reports with
items from many data elements coming down on the rows.

Value dimension and aggregation operator in event analysis: In event reports
and visualizer you can define which data element to use as the metric to
display in the report or chart. You can also define which aggregation operator
to use for that metric. E.g. you can now display the average weight or age in
the report. You can enable this from “Layout” in the “Value” box.

Enrollment output type in event analysis: In event reports and visualizer you
can select the output type, which refers to how the system counts the number of
matches for the criteria. You can select between number of “events”, number of
“enrollments” and number of “tracked entity instances” (persons). This is
useful for tracker programs.

Hide n/a options in event analysis: In event reports and visualizer there is a
new option for hiding n/a data items. Often, several data elements might not
have a value for events which will lead to rows and columns with a count of
n/a. From “Options” > “Hide n/a data” you can now easily hide all those items
when desired.
Demo | Screenshot
This relative periods: New relative periods have been added for this week, this
month, this quarter and this six-month in all five analysis apps and analytics
Web API.
Screenshot
Aggregation type: In data visualizer you can specify the aggregation type for
the chart items. You can select between sum, count, std dev, variance, max, and
min. This is useful when more than one aggregation type is needed per data
element. Std dev and max/min are useful to look for outlier values and data
quality issues. The demo shows std deviation for immunization doses
administered.
Demo | Screenshot
Identifier schemes in analytics output: You can choose between using UID, code
and name as identifiers when you download pivot tables or access the analytics
Web API. This is useful e.g. when you want to export aggregated data and
exchange it with a third-party system which are synchronized on meta-data codes.

CONFIGURATION AND SYSTEM MAINTENANCE FEATURES----
Variable substitution in SQL views: You can insert variables directly in SQL
views and pass in values to be substituted in the request URL. This adds
flexibility in how you create SQL statements, and can improve performance since
you can place variables in the main where query, as opposed to filtering the
entire result set as it is done with the existing criteria function.
Demo | Docs | Screenshot
Materialized SQL views: You can create materialized SQL views. In the “add new
SQL view” screen you can select “Materialized SQL view”. Materialized views
store a copy of the actual result set of the view query. This performs better
than regular SQL views which needs to be retrieved from the underlying table
each time. The down

Option set and long text attribute types: Dynamic meta-data attributes can now
be of type option set, which display as a drop-down selection field; and long
text, which has no length limit and displays as a text area.
Demo | Screenshot
Resend user invitations: In the user app > list of users, you can re-send
invitations to create user accounts by clicking on an unrealized account
invitation. This is useful as people sometimes fail to notice the invitation
email or it ends up in spam filters. Requires full system authority.
Screenshot
Identifier and code matching in GML import: The GML importer lets you match
incoming features using UIDs and codes. Previously only matching name was
supported. This is useful for scenarios where established identifier / code
lists are in use.
Docs
Footers in email messages: A footer with a reply link has been added to email
messages. This is useful in order to easily reply to messages which are read in
an email client. This requires that you set “Server base URL” under general
settings and configure an SMTP server under email settings.
Demo
Offline org unit level cache per org unit level: The number of organisation
unit levels to cache offline for data entry purposes can now be controlled per
organisation unit level. This is useful for global system implementations, e.g.
where you have global users which do not need to do offline data entry and do
not want to wait for a very large number of org units to be cached.
Screenshot
Analysis about page: All analysis apps now have an about page which shows time
since last analytics table update, current DHIS 2 version, revision and
username. This also applies to the about page under profile. This is useful
when debugging and supporting end-users. Click on About in the top right corner
on the demo.
Demo
Separate logs for background processes: Output from processes such as analytics
table generation, data exchange and data synchronization are now written to
separate logs. Main log is also written to a dedicated log file. These logs are
found under DHIS2_HOME/logs and are capped at 50MB. Main logs are still written
to standard out.
Docs
TRACKER AND EVENT FEATURES----
Location in map: In event capture you can set the location in terms of
longitude and latitude for where an event took place directly from Google Maps.
This requires that coordinate capture is enabled for the program. In the add
new event form, click the blue icon next to longitude to open the map, then
click on the map to set the location. Try it out on the demo on the
“Information campaign” program.
Demo | Screenshot
Search in org unit tree: In tracker capture search you can now search across
all organisation units that you have access to by opening an org unit tree
inside the advanced search area. This is useful as you can now search across
organisation units independently of which organisation unit you have selected
for registration of persons in the left-side tree selector.
Demo | Screenshot
Enrollment status filter in search: In tracker capture search you can now
filter on persons based on their enrollment status. The options are active,
completed and cancelled enrollments. Use the 4 icons at the top to filter.
Demo | Screenshot
Custom form for person registration: You can define custom forms to use for
registration of people and things. This is useful when you have detailed
requirements of need for scripting for registration. You can create custom
registration forms from Programs / attributes > Tracked entity form. Check it
out on the demo by registering a child for the “Child Programme”.
Demo | Screenshot
Nicer program summary: The tracker program summary report is now easier to read
and looks better. Each program stage appear in tabs, and each person or thing
is displayed with event date and organisation unit.
Demo | Screenshot
Next and previous in dashboard: In tracker capture dashboard you can quickly
navigate between persons and things by clicking on the next and previous button
in the top left corner.
Demo | Screenshot
Tracker dashboard layout: The tracker dashboard now remembers the position of
each widget between each time you access it.
Demo
Periodic events: You can capture events at fixed, periodic intervals. The
period type of the interval can be set in the program stage management. When
creating a new event for that stage the user is asked to enter a period, e.g. a
month, instead of the usual date.
Screenshot
WEB API FEATURES----
Translations: Translations are now included in the standard meta-data payload,
meaning you can easily export and import meta-data translations. Also, a locale
query parameter can now be supplied to all meta-data resources to get the
meta-data translated according to the desired locale.
Docs
Enum options: All valid options for enum-type properties are exposed through
the API payload. This makes it easier to use such properties in apps. See e.g.
report table > aggregation type property.
Demo
Meta-data validation: Meta-data is now being validated according to constraints
such as min and max-length and not null. You can investigate current
constraints and validate your payload against the schemas resource to check
validness.
Docs
Merge strategies: When importing meta-data now you can now define whether the
API should merge existing properties or overwrite when updating objects.
Docs
Approval level parameter in analytics: You can define an explicit approval
level in analytics request which tells the system to only include data up to
that approval level in the aggregation.
Docs
Data validation: Data values for a data set can be validated according to
relevant validation rules using the new validation resource.
Docs
Identifier schemes for event export: You can now choose between using UIDs or
codes as identifiers for event export payloads.
Docs
Preheat cache for data import: The dataValueSet data import resource now
supports a preheat cache option for controlling whether to load all necessary
meta-data into memory before import.
Docs
Scheduling: All background tasks such as analytics table generation and data
monitoring can be scheduled through the new scheduling resource.
Docs
Field filtering: Support for filtering of fields has been added to the schemas,
properties and dimensions resources.
