How to execute a function on module installation properly?

Question

I recently needed to execute a function on module installation.

My research has brought up two different ways:

Using the _init() function of a class
Using the data.xml file (noupdate="1") to call a function of a model

Which one is recommended? What are the differences? Is it version dependend?

Thanks!

Hi,
The noupdate parameter is used to indicate if the values in the xml file must be re-imported when a module in updated. noupdate="1", if we delete a data record and update the custom module, the deleted data not will be imported again._init() function is used assign values to the data members of the class when an object of class is created. The better option for your question is _init() function.
Regards
