Hi all,

 

We are wondering about the best form to import in DHIS2 data from legacy
applications.

 

In chapter “26.4. Transforming data - a Java route” of the User Manual we
see that there is a way to do this integration using Java routes, but we are
having some difficulties in implementing a proof of concept.

 

In our PoC scenario we have a XLS file sent by an external application
(DataValues.xls in attach). Our idea is to create a Java route in order to
import all data values that exist in that file.

 

Following the tutorial “Customer 3: Excel via e-mail” presented in the
Apache Camel page -
<http://camel.apache.org/tutorial-business-partners.html>
http://camel.apache.org/tutorial-business-partners.html - we have been able
to transform the XLS file in a list of DataValue objects. 

 

Basically, we only had to create a XLSDataIn route and a ExcelConverterBean
(files in attach). The XLSDataIn takes an InputStream of an XLS file and
calls the ExcelConverterBean. The ExcelConverterBean iterates through the
file, and for each data value row, creates a new DataValue object and adds
that object to a list of DataValue objects.

 

Now we are having some issues because we don’t know the best way to insert
these data values in DHIS2.

 

The questions we are having are:

1.       The approach that we have used to implement our PoC is the correct
one? I mean, XLS -> List<DataValue> -> import is correct or we should use
XLS -> CSV -> import?

2.       How should we proceed, after the XLS file has been processed by the
ExcelConverterBean?

 

 

Thanks for your support,
