I need good documenting software recommendations.

[Blix775]

I am currently building an application in .Net Core in MVC and I need some programs that will work in Ubuntu to create the following things:

Entity Relationship Diagram
Data Dictionary
Data Flow Diagram
Unified Modeling Language

I have googled but I have not found something I like. I was checking out Umbrello and it seems it is no longer under development. So can anyone give me any recommendations?
I am using Ubuntu Budgie 18.04.

Perhaps dia will be of interest - except for the Data Dictionary.

It seems to no longer be supported.

It has now been part of the Gnome project for several years and as such I would regard it as supported: https://gitlab.gnome.org/GNOME/dia

In any event, there is a current Ubuntu package for it:


$ cat /etc/lsb-release
DISTRIB_ID=Ubuntu
DISTRIB_RELEASE=18.10
DISTRIB_CODENAME=cosmic
DISTRIB_DESCRIPTION="Ubuntu 18.10"



$ sudo apt-get install dia
