Database Connection

Hello,

I have created several models on manufacturing lines but I am now looking to create a new model which is essential a digital twin. I have access to an SAP database where the data I need is stored. The data is mostly numercial (quantities + times).

I have read about the database connector but have not yet been able to test it as I am waiting on a few things. I'm seeking any advice about how I should go about this and how I should use this database? Should I be running SQL through FlexSim itself via code editor or otherwise?

Also is there anything specific to using SAP that I should know?

Thanks in advance.

Software Version:

FlexSim 25.0.0

What data do you want to retrieve, store or update in/from the SQL database? Also have you checked it has been deployed on a standard DB or has an ODBC connector, or is it on a (proprietary) cloud service?

You can predefine import/exports via the DB Connector's properties GUI or you can use FlexScript directly. Imports use SQL while the export reads from a FlexSim table. To export using FlexScript you'd probably use sql INSERT INTO statements.

I won't be updating the database, just retrieving data from it. The data varies but most of the data I need is times in seconds. Specifically cycle times of machines. I want to get the latest of these times to import the average into the model.

The data is on a standard DB, no connector.

@Jason Lightfoot The current plan is to import without using a connector. Just to confirm...here I will be importing using SQL in Flexsim?

Should this SQL be exclusively in the import logic or can this SQL be used anywhere in Flexsim?

Wherever you can use Flexscript in the model you can use it to import data - whether this makes sense as the model runs is another matter.

I've also been able to load external data and create empirical distributions from that - which would save you from having to use just the average value - you could sample empirical values or fit a curve to the data.
