Erwin 2021 - Selecting DynamoDB as Target - amazon-dynamodb

We recently upgraded to Erwin DM 2021 R1 and I am attempting a POC for a DynamoDB design. However, I don't see it listed as a Target Database option when creating my Erwin model.
What am I missing?
Thanks

Flyway switches to Teams edition without any teams features being used

I have recently started using the baseline and repeatable migrations in my app. Although I don't seem to be using any teams-edition features, yet flyway somehow switches automatically to the Teams edition instead of Community edition, and shows a message :
Flyway Teams Edition 8.2.0 by Redgate
Flyway Teams features are enabled by default for the next 27 days. Learn more at https://rd.gt/3A4IWym
Previously we had eight versioned migrations V1__xxxx.sql to V8__xxxx.sql
Now we have made the following changes :
All the eight migrations, plus some other init scripts have been combined into a single migration V1__seed-data.sql
Repeatable migrations have been put into R__xxxx.sql
Some placeholders have been placed into the flyway.conf like : fileflyway.placeholders.app_db_name=${APP_DB_NAME}
For our existing Production DB, which was already migrated till V8, we have Dropped the flyway_schema_history table and used the "flyway baseline" command with an environment variable FLYWAY_BASELINE_VERSION=1
After this, the flyway_schema_history shows us this result :
But after these changes, we are seeing the "Teams edition" message as above.
Earlier it used to show :
Flyway Community Edition 8.2.0 by Redgate
I am quite sure looking at the flyway documentation that we haven't used any Teams edition features. https://flywaydb.org/documentation/usage/commandline/baseline
Now I have 2 questions :
What caused flyway to switch to Teams edition without teams features being used?
What happens once the trial period ends? Does flyway block all our migrations in the future unless we buy the license?
Update Flyway to the latest version; the "Auto trial" feature created the "Teams edition" message you're seeing here, and was removed in Flyway 8.4.3 - release notes.

Saving veins data in a SQLite database

Good morning everybody.
I'm using Veins 4.4 and Omnet++ v4.6.
Is it possible to save data collected through a Veins simulation (i.e. WaveShortMessage fields) in my SQLite DB?
thanks in advance
BR
SQLite support for OMNeT++ 5.1 is a work in progress. There will be a preview release before the holidays so if you can port your code OMNeT++ 5.1 (PRE2) you will be able to configure an SQLite vector manager (instead of the current text based one) which will write out the vector data to a SQLite database. A preliminary version was presented at the 2016 OMNeT++ Summit: https://summit.omnetpp.org/archive/2016/assets/pdf/OMNET-2016-Session_3-03-Presentation.pdf

What is the best way to migrate or export/import data from Microsoft AX4 to AX7

On the one side I have a working AX4 environment and now want to upgrade to the new AX7.
Therefore we need some tables of the database to be imported or migrated to the new one.
What is the best way to achieve that?
There is no direct upgrade path from AX4 to AX7 (AFAIK), nor is there a way to directly move objects.
How many objects need migrated? You're essentially left with two options.
XPO objects into AX 2012 staging environment, then upload the AX 2012 modelstore to LCS and that will migrate the code and create the migration project in AX7 (See https://ax.help.dynamics.com/en/wiki/upg101-preparing-for-migration/)
Recreate the objects by hand :(
A little more detail on (1.) is in AX 2012, instead of the code being stored on disk in a bunch of layer files, it's stored in a separate SQL database. And a modelstore is conceptually a *.bak file of that database. So when you import an XPO into AX 4.0 CUS layer, it ends up in axCUS.aod; likewise when you import an XPO in AX 2012, it ends up in the modelstore in the CUS layer.
To uplift code in AX7 from AX12, you basically take that *.modelstore file and .zip (compress) it and upload it on lcs.dynamics.com. You also must connect LCS to VSO (visual studio online), because it creates tasks and things to do.
You then wait a while (usually about an hour, but I've had it take 1-2 days when they were changing the framework), then you have the objects in VSO and you can sync them to your AX7 environment.
EDIT: Regarding data from AX 4.0...I'm definitely not yet an expert on getting data into AX7 but they generally push data entities, which are essentially an abstraction of parts of the database. If it's one-time data moves, you can possibly use the Excel data connector.

Copying company data from one server to another, Ax 2009

We will soon be migrating company data from our pre-production server to production with Microsoft Ax 2009. I believe that there are two ways to do this and would like to know of any issues that might arise with the second. This is migrating data across servers and not a simple case of duplicating company data on the same Ax 2009 service.
Use the Import / Export functionality. Administration -> Periodic -> Data Export/Import, create a new definition group and then export it. Recreate the same definition group on the second server then import. Here's an example how to do it for Ax 2012.
Export/Backup the SQL Server database from the first server and restore it over the second. We then would merely be eliminating our test and template company data from the second server. The Ax servers need to have the same patches and development layers installed first. I note that we would need to edit the ServerID value within SysServerConfig table afterwards.
Thanks
The Backup/Restore way to do it is at least 10 times faster.
There are some issues to be aware of though:
Ensure that references to the file systems are correct (e.g. Document parameters)
Server configuration setup
UAC cache file issue described here
Update 1:
For AX 2012 you will also need to have the same model store on the production server as well, this can be accompliced by using database backup/restore or using export/import of the object store as described here.
Update 2:
Update 1 is partly rubbish, both data and model store are copied in the SQL backup/restore. No need to synchronize the database afterwards! But it may come as a surprise.

Oracle 11 g release 2 sample schema

I installed Oracle 11g Release 2 on a windows 7 laptop and created a database using DBCA. In one screen there is an option to create sample schema but it was greyed out so I could not select it.
I searched the dbhome\demo\schema\human_resources directory but there is only one file in it -
hr_code.sql(It created triggers in hr schema). There is no sql to create hr schema or populate schema tables. I searched the net to download the scripts but no idea where to get them. Can you help me
You can download the script from here.
Are you referring to the ASP.Net Membership / Role / etc schema? It's in <oraclehome><11g>\ASP.NET\SQL
