MDS is a part of the SQL Server enterprise license. I am not aware of any additional costs.

The MDS/DQS are included in SQL Server Enterprise Edition.

Microsoft MDS is cost-effective because it comes with SQL Server Enterprise Edition at no extra software cost. The main expenses are for deployment, but it saves money by reducing the need for custom data forms. It includes an Excel add-on for easy data import and offers valuable features like business rules and approval processes for data. It is a valuable tool with low additional costs.

None as our in-house staff did the setup. There is no day to day maintenance needed. The 2016 version is no longer supported by modern browsers so high recommend only using the latest (2019) version available.

Microsoft MDS is an expensive solution. 

The solution is a bit expensive. We pay for it on a yearly basis. 

I'm not sure of the exact costs as I don't handle the payment processes. 

The solution does require a license and we have enterprise licenses.

MDS alone is a free product, but it comes with the complete package of Microsoft SQL Server. So while you are purchasing SQL Server Pro version or licensed version of SQL Server you also get SSIS, MDS and DQS. 

The price of the program has gone up, so I would like to see better pricing. But I like it that there are no additional fees that we have to pay.

With Microsoft, we buy everything though an agreement, so we purchase volume licensing every year. That is how our licenses are managed.

The pricing of this solution is good.

MDS is packaged as part of the Microsoft SQL Server platform and no additional license is required.
