Tracking Data Model changes
Hello everyone,
For one of my assignments, I need to find out entity changes that took
place between an older release and the latest release.
One of the solutions that came up was comparing the database using MySQL
Workbench or some other utility. I found around 60+ new entity changes and
a lot of minor field changes since last big book was published (OFBiz 9 I
suppose).
It's fascinating for me that around 8 years passed since then and data
model still stands well (Kudos to Universal Data Model that we followed in
OFBiz)
Just a proposal, since we don't have so many frequent changes in the data
model. It will be good to have a page or some other method defined to keep
a track of such changes.
I feel such information can be quite helpful when migrating from an older
to some newer release.
Please share your thoughts.
Thanks and Regards,

Hi Taher,
You mean something more than https://cwiki.apache.org/confluence/display/OFBIZ/Revisions+Requiring+Data+Migration+-+upgrade+ofbiz ?
If yes, why?

Re: Tracking Data Model changes

That would be a much effective solution.
As far as https://cwiki.apache.org/confluence/display/OFBIZ/
Revisions+Requiring+Data+Migration+-+upgrade+ofbiz page is concerned I find
it quite absurd that we provide information based upon only revisions while
users deal with releases.
Though it would be better to link it to data migration page so that user
gets all information through a single path.

Hi Aditya,
One way we could use and is already used for the Gradle and Birt Flexible documentation in wiki is to create README.md files, uses Pandoc to generate
a HTML file from it in tools\wiki-files and import this file in wiki using the HTML import macro.
Doing so we follow both way you suggested. So users have it in 2 places while it's only maintained in one place where it's versioned (though
Confluence also versions pages)
Maybe an overkill in this case though. Since we have already
https://cwiki.apache.org/confluence/display/OFBIZ/Revisions+Requiring+Data+Migration+-+upgrade+ofbiz to start from

Re: Tracking Data Model changes
Posted by Aditya Sharma <ad...@hotwaxsystems.com>.
I see two ways to do that
1. A page maintained on Confluence where all the data model changes are
updated. Here, we can have a page maintained for the upcoming release when
the release is out we make it sub child titled with the release name.
2. A file is maintained in ofbiz-framework code base itself that goes with
the package with information about data model changes. Whenever someone
downloads the package this file will help track data model changes that
come with the package.
We can make it part of contributor's practice to update it whenever such
changes are done.
Which way should we go?

+1 for the documentation of database changes.
We alreadyy do this for customer projects, along with (database
specific) data migration scripts.
I'm not sure if we can afford to provide sophisticated additional tool
support which is maintained continiously?
As a conclusion, I think we should setup a convention that any database
model change has to provide a proper change log and migration script for
the embedded database (if applicable).

Re: Tracking Data Model changes
Posted by Taher Alkhateeb <sl...@gmail.com>.
Groovy scripts are also great and can do the job. To comment on the
"advantage" of something like flyway or liquibase I can try to list
some:
- The scripts might get too big or complex to accommodate different
databases and platforms.
- Out of the box, these solutions are database independent
- Ability to redo / undo on schema changes
- Supporting declarative style for schema definitions based on
multiple formats (YAML, XML, JSON, etc ..)
- The DSL is easier to use (declarative and short)
So in short, both solutions are viable, and existing solutions might
be a bit easier to implement especially if you consider additional
features in those solutions.

I'm in favor to tracking the different migration but at this time I
didn't see the advantage to use flyway or other instead of manage easily
by ofbiz throw groovy script.
I'm available to help for design or create a POC do realize it because
many time in the past (and currently ow) I want to refactoring some
code/db schema with data migration but we haven't clean process to do that.

Thank you all for your valuable inputs.
We have added the markdown file to trunk with all the data model changes
from Release 9 to Release 17 at R1818765 and it will soon be part of the
next release. The page is also added as child page to wiki page Revisions
Requiring Data Migration - upgrade ofbiz
<https://cwiki.apache.org/confluence/x/LoBr> as Data Migration by releases
<https://cwiki.apache.org/confluence/x/07JzB>
Thanks Sonal Patwari for the efforts put into gathering information for the
Big Book.
Thanks Jacques Le Roux, Michael Brohl, Pranay Pandey, and Deepak Dixit for
providing personal attention to the whole effort.

Re: Tracking Data Model changes
Posted by Aditya Sharma <ad...@hotwaxsystems.com>.
Hello all,
I have created a ticket here
<https://issues.apache.org/jira/browse/OFBIZ-9902>.
I will be adding information about data model changes between OFBiz.9 to
OFBiz.17.11 in the initial file.
As commented on the ticket,
The file will have the format:
Entity Changes:
Here we will have a bulleted list with entity names and the revision number
1. Added Entities
2. Removed Entities
Field changes:
Here we will show data in tabular form in following format:
entityname | field | action | isPK | revision
Any suggestions are warmly welcomed.
Thanks and Regards,
*Aditya Sharma* | Enterprise Software Engineer

+1 for tracking datamodel changes together with data migration scripts
In our customer projects, we track every change in a simple text file in
the source code repository. It contains description of the changes,
references to issues or requirement documentation and SQL scripts for
migrations.
In OFBiz, we should at least provide SQL scripts for the embedded Derby
database, maybe there will be contributions for other databases as well.
Something like db-changelog.derby.txt, db-changelog.mysql.txt or similar.
Cheers,
Michael

Re: Tracking Data Model changes
Posted by Taher Alkhateeb <sl...@gmail.com>.
Hi Ashish,
With respect to Jacques' question, I kind of already answered in that
it is not only documentation but also automation.
Now with respect to which releases to incorporate, it really depends
on what the community decides. I would personally prefer to not go any
earlier than 13, or preferably just 16 to trunk, which means we design
this solution for the future, not necessarily the past. The powerful
thing in using something like liquibase is that not only do you change
the schema (the entity engine can do that partially) but you also
decide on how to migrate the existing data to the new schema. For
example, you might need to split a field to two, or merge two fields,
and so on and so forth.
Anyway, this is only an idea if people are interested in it. The
original idea of just documenting is also perfectly reasonable and
beneficial.

+1, Taher. I will wait for your comment on Jacques question, we already
have a document but I think the automated script that can be implemented
here. Liquidbase and flyway seem to be promising solutions!
One question always comes to my mind: Can we say that automated scripts
will support the migration from last two or at max three known releases?
I think we should not put the effort in building the migration script that
could migrate ofbiz earlier version(Let's say Ofbiz 10 or 9 or 4) to the
latest version. Please share your thoughts on this.

Good idea! Why not take it a step further, and write data migration
scripts? They will serve two purposes in one: 1) document changes 2)
automate upgrades.
You can experiment with solutions like liquibase or flyway

Hello everyone,
For one of my assignments, I need to find out entity changes that took
place between an older release and the latest release.
One of the solutions that came up was comparing the database using MySQL
Workbench or some other utility. I found around 60+ new entity changes and
a lot of minor field changes since last big book was published (OFBiz 9 I
suppose).
It's fascinating for me that around 8 years passed since then and data
model still stands well (Kudos to Universal Data Model that we followed in
OFBiz)
Just a proposal, since we don't have so many frequent changes in the data
model. It will be good to have a page or some other method defined to keep
a track of such changes.
I feel such information can be quite helpful when migrating from an older
to some newer release.
