MDS – Brief history

Microsoft acquired Stratature MDM product

titled +EDM in 2007

Shipped with SQL Server 2008 R2

Almost useless, in that state

Major improvements in SQL Server 2012 release

No improvements in MDS for SQL Server 2014

26-11-2014

Scenario

26-11-2014

Approve or Dismiss

Scenario

Have to be able to calculate stockvalue after

provision and excess

Have to be able to generate import file to

Navision after calculation

Have to be easy to use, for controllers

MUST use data from Datawarehouse

26-11-2014

Solutions

Develop an application solely for this purpose

Look for standard software from Microsoft,

that we already paid for

Small changes / custom development is allowed

Keep the manual process

26-11-2014

We chose

We chose Master Data Services from Microsoft

Comes out of the box with SQL Server 2008r2/12/14 (Enterprise and BI)

Fairly easy to use

Add-in for Excel

Fairly easy to implement business rules

Custom workflows and Custom Business rulescan be implemented

SQL Server already bought and paid for

MDS

Solution implemented

Data read daily from datawarehouse

Until freezedate is hit, the load stops

At freezedate, data is moved to separate

MDS entities (lists)

When freezeperiod is over data, is loaded

again.

26-11-2014

Solution implemented

26-11-2014

1. Check if Version exists in MDS

1. Yes - Then delete (to empty)

2. No – Then copy from template

2. Truncate MDS staging

3. Move data into MDS staging

4. Load data MDS staging to Model

5. Validate Model

MDS API

Most operations can be started by T-sql or by

stored procedures in SSIS

Open API, not like in Data Quality Service,

where everything is encrypted

Not that much documentation at hand

A few blogposts so far, community is building

Use Profiler to listen and catch T-SQL and

Stored procedure calls from MDS manager

26-11-2014

Profiler Demo

26-11-2014

Set up profiler

Navigate MDS manager

MDS as application

Either in Browser (silverlight)

MDS as application

Or in Excel

26-11-2014

MDS List

The controller can only see and

edit his own data

And only the columns that need

information from him

Custom Workflow i MDS

Almost no documentation – one article on

technet http://tinyurl.com/nhaknla

Must be installed by hand

No good debugging

Blogpost on the way describing this in details

Workflow DLL – C#

Remember to add references to the MDS workflow

Microsoft.MasterDataServices.Workflow;

Microsoft.MasterDataServices.WorkflowTypeExtender;

XmlNode xmlBusinessRule =

dataElement.SelectSingleNode("//ExternalAction/Server_URL");

string BusinessRule = xmlBusinessRule.InnerText;

26-11-2014

Workflow DLL – C#

26-11-2014

using Microsoft.MasterDataServices.Workflow;

using Microsoft.MasterDataServices.WorkflowTypeExtender;

namespace EaOBusinessRule

{

public class GNCustomWorkFlow : IWorkflowTypeExtender

{

public void StartWorkflow(string workflowType, System.Xml.XmlElement dataElement)

{

XmlNode xmlBusinessRule = dataElement.SelectSingleNode("//ExternalAction/Server_URL");

string BusinessRule = xmlBusinessRule.InnerText;

switch (BusinessRule)

{

case "CalculateTotals":

ExecuteBusinessRule_CalculateAfterAdj(workflowType, dataElement);

break;

//case "do something else

//ExecuteBusinessRule_CalculateSomethingElse(workflowType, dataElement);

default:

break;

}

}

Workflow DLL – C#

Attribute names in XML

Blanks will be replaced by _x0020_

dataElement.GetElementsByTagName

("Adjustment_x0020_Obsolete")[0].InnerText;

26-11-2014

Workflow DLL – C#

Look up attributeID’s in MDS datamodel

EntityID is read from MDS XML

dataElement.GetElementsByTagName("Entity_ID")[0].InnerText;

SELECT CAST([ID] AS VARCHAR(100)) AS [ID]

FROM [mdm].[tblAttribute] AS attributes

WHERE attributes.[Entity_ID] = " + EntityID.ToString() + "

AND attributes.[Name] = 'Total Provision'

26-11-2014

Custom Workflow i MDS

Configured by XML

26-11-2014

<applicationSettings>

<Microsoft.MasterDataServices.Workflow.Properties.Settings>

<setting name="ConnectionString" serializeAs="String">

<value>Server=10.200.10.160;Database=MDS;Integrated Security=SSPI</value>

</setting>

<setting name="WorkflowTypeExtenders" serializeAs="String">

<value>MDSWFS=EaOBusinessRule.GNCustomWorkFlow, EaOBusinessRule, ….</value>

</setting>

</Microsoft.MasterDataServices.Workflow.Properties.Settings>

</applicationSettings>

Debugging Custom Workflow

Easiest way to debug is writeing to the

console

Start workflow service in ”console mode” on

the server where MDS is running

Microsoft.MasterDataServices.Workflow.exe

–console
