How to update existing data in Master Data Services SQL Server 2022?

I am learning to use Master Data Services for the first time and currently stuck on **updating** existing data. This is also my first time using SSIS so I am currently learning on how to use SQL Command to update data.
**Overview data load workflow**
1. Data is being stored into a staging table (DQS_STAGING_DATA)
2. When load successful, data then will be loaded from DQS_STAGING_DATA into each staging table in MDS with import type 0 (Ex: stg.Person).
**My current SSIS workflow**
[Loading data into MDS stg.Person and stg.Company](https://i.sstatic.net/LBhe3Ldr.png)
**What I have tried**
Change import type from import type 1 to 0.
> 1: Create new members only. Any updates to existing MDS data fail.
> 0: Create new members. Replace existing MDS data with staged data, but only if the staged data is not NULL.
How do I update data inside of the stg.Person and stg.Company using my current SSIS workflow and ensure that Master Data Excel Add-ins will reflect the new data? Both of these staging tables also have their own subscription view.
**My expectation**
1. A simple to follow step by step and beginner explanation to update existing data in Master Data Services.
2. Comment and feedback on my current SSIS pipeline.

We are upgrading master data services (MDS) of SQL2016 to SQL2019.Is there a way to run excel 2019 addin for connecting to SQL 2019 MDS along side(parallely) with excel 2016 addin for connecting to MDS 2016 on user's desktop machine so that same user can connect to MDS 2019 with excel 2019 and MDS2016 with excel 2016 simultaneously?.The reason we want to run parallelly is we doing a migration for UAT environment to MDS2019 and we don't want to restrict their access to MDS 2016 till the time they are on prod.
We are open for any solution like techniques (if any) from desktop virtualization perspective or anything from SQL...Appreciate all the responses

Is it wise to change the Page Verification to CheckSum? Or should we wait for Microsoft to release a new version of MDS?

SQL Server Master Data Services database history by snapshots
I'm involved in a project where there is SQL Server 2012 Master Data Services used.

I'm involved in a project where there is SQL Server 2012 Master Data Services used. There's a requirement to save a version of the database contents in certain point of time, say, every month or a quarter or so and possibly replacing previous versions on a yearly rhythm. That is, if a monthly history of database versions is used, there will be at most twelve different snapshots at any given time.
I'm curious and hence two questions:
* Is this a preferred way of doing this?
* Would there be a better way?
For what I've seen, from a developer perspective, snapshots are utilised for example for reporting purposes, but dropped soon after they are done. It seems they impact performance and perhaps make backups and restores more difficult.
https://en.wikipedia.org/wiki/Slowly_changing_dimension) and it looks like the (great) majority of data does not change. What I know, or believe is that there are nightly bulk loads, but mostly the data loaded should be the same as it has been, and changes are mostly new items plus some small modifications and some additional attributes maintained purely by the data stewards. Then looking Technet regarding [Database snapshots](http://technet.microsoft.com/en-us/library/ms175158.aspx) it looks me it's difficult to run the system efficiently (e.g. I/O) and reliably (backups and restores) in presence of multiple snapshots, which do carry an operational and contractual purpose in this case.
Maybe I shouldn't fret or this. This doesn't even look like I have any real questions here anymore than
* Would it be normal to version database data in snapshots? Be it an operational database or a MDS one.

I have an instance of SQL Server Master Data Services installed, there are users managing the master data via the Excel add-in, now we're ready to integrate the master data into products. We've created and published subscription views, but users can't connect to the server to query from them. Our hope is to use PowerQuery in Excel to enable users to leverage the master data, so we're trying to figure out how best to manage the permissions.
**Are permissions to query subscription views managed separately from the master data permissions managed in the browser UI?**

Implement AKA in SQL Server Master Data Services
I'm working with a bunch of scientists and we're trying to implement a master data solution for the ingredients they use in formulations.

I'm working with a bunch of scientists and we're trying to implement a master data solution for the ingredients they use in formulations. The problem with their historic data is Scientist #1 will use Ingredient A but call it 'Alpha 100' while Scientist #2 will use Ingredient A and call it 'A100'. We want to implement Master Data Services to make sure the way the materials are characterized scientifically is consistent and then develop a template that will force scientists to pick ingredients from a drop down. However, Scientist #1 will be looking for 'Alpha 100' and Scientist #2 will be looking for 'A100' in a dropdown, so I'm curious, **is there a way to implement an AKA (also known as) solution is SQL Server Master Data Services?**
I was thinking it could just be a bunch of extra attributes that can be null and then unpivot them in a view, but that doesn't feel elegant.

Installed the Excel plugin too, but unable to connect to the web app. I keep getting this error "there was no endpoint listening at > that could accept the message. This is often caused by an incorrect address or SOAP action. See InnerException, if present, for more details (mscorlib)"
The URL is correct, I don't have extra items in the URL (like default.aspx etc). It isn't https, just http. The same URL works in the browser.
What else can I check?

I have recently automated the SQL patching of ~200 development servers.
Currently we have 6 servers that run the Microsoft Master Data Services feature.
After a SQL patch is applied there is a manual step to go in and open Master Data Services Configuration Manager and do an upgrade of the schema.
Since this kills my automation for those 6 servers I am trying to find out if there is a programmatic way to run this upgrade process after applying the SQL patch.

Until now, we have used stored procedures for data massaging and cleansing but we have now decided to move to using Data Quality Services (DQS) and Master Data Management (MDS) in our data warehouse projects.
There is one very common function which we use in our stored procedures - it trims and replaces the
, character with white space e.g.:
UPDATE [Table] SET Column=(ltrim(rtrim(replace(Column,',',''))))
I have spent hours to figure out a way to achieve this using DQS and MDM but couldn't find any way to achieve the same goal.
I would really appreciate if you guys can help me out with this.
In fact, thank you already for your precious time.

SQL Master Data Services database has huge leaf member staging table - can I purge old records?
One of our SQL instances has a large MDS database, and virtually 100% of the size is due to a 300+ million row table named `stg.Stg_Project_Leaf`.

One of our SQL instances has a large MDS database, and virtually 100% of the size is due to a 300+ million row table named
stg.Stg_Project_Leaf. It recently started blowing up our weekly index rebuilds, so I need to figure this out.
From what I can tell, this is a [Leaf Member Staging Table](https://technet.microsoft.com/en-us/library/ee633854(v=sql.110).aspx) for a "Project" entity, set up and automated (by a prior consultant) as a part of an ETL process that builds BI cubes/reports.
Looks like it has been processing about 10k rows per half hour for the past *several years* and has never been purged. When I check the ImportStatus_ID, though, I see 0 rows waiting to be processed. (Most are 1 - succeeded, less than 1% are 2 - failed.)
**Can I just TRUNCATE this table?**
This system is being used in an automated fashion, its not like people are logging into the MDS console and individually monitoring and rolling back changes. I found some references to stored procedures that purge these tables (mdm.udpStagingClear or maybe mdm.udpDeletedMembersPurge), but I'm not sure which of those is the one I'd need, nor do I know if they would blow up the log if they tried to do 300m rows at once.

I just installed MS SQL server, IIS and Master Data services, 2016 version. Everything seems fine, except the web application doesn't work. I am able to go to the home screen, but there are no models/versions listed in the Model: and Version: dropdown, even though I added two models using the MDSModelDeploy utility. The UI doesn't give me any error, but Chrome dev tools shows "401 Unauthorised" error.
So basically, the url "http://server-name:port/api/Models " is unreachable, giving "authorization has been denied for this request" error.
I've checked the usual places (allowing anonymous auth etc), they all seem correct. What else should I try?

Is the source system typically one of the fields used to uniquely identify business key?
One of the key components of designing a data vault is identifying **enterprise-wide unique business keys** ("business key" AKA "natural key").

This seems like the obvious solution, but I've not seen it mentioned in any of the Data Vault modeling documents I've found, so I wonder if there's some reason not to use this approach.

OrderID to identify records in an Orders table, because when you add another orders table from another source system (e.g., a brick-and-mortar store launches an online store), there may well be collisions.
In Data Vault best practices, should one include the name of the source system as one of the fields used to uniquely identify a record, when adding it to a hub table? Rather than searching for some combination of fields in Orders which will *hopefully* be universally unique ({ CustomerID, OrderID, and OrderDate }, maybe), one could identify brick-and-mortar orders with { "Brick-and-Mortar Order System", OrderID }, and one could identify online orders with { "Online Order System", OrderID }:
This seems like the obvious solution, but I've not seen it mentioned in any of the Data Vault modeling documents I've found, so I wonder if there's some reason not to use this approach.

I am now going to install Windows authentication to correct the problem. However, I have looked at the link and Windows 10 Pro is not listed as being compatible with SQL Server 2014 Developer edition. Is that correct?

I'm researching and investigating about all possible ways to create a master data database for my portfolio of applications.
To give you a quick overview, an example will come in handy:
I want to create a Users database that several different applications will use. Instead of creating user tables in each application I need to centralize in one point all these users data and their permissions, for each application.
All this applications have MS SQL server as rdbms, so the Replication engine with a single publisher and several subscribers is an option. However, I would like to know if there are other alternatives, and what's more important, if any of these alternatives could be platform independent (for example, a master DB designed in MySQL with two slaves which could be Oracle and MS SQLServer).
Thanks for your help!!
