I mentioned in my developerWorks status at the middle of last year that I was working on a redbook on MDM and BPM integration. Well I am pleased to announce that this redbook has now finally been published!
The redbook titled : 'Aligning MDM and BPM for Master Data Governance, Stewardship and Enterprise processes' provides a detailed insight into the business benefits of running MDM and BPM projects side by side. It explains how combining the benefits of IBM InfoSphere MDM and IBM Business Process Manager to provide a platform for Master Data Governance and Stewardship, providing you with an industry lead
We'd love to hear what you think....

In Version 11 of InfoSphere MDM, some big changes happened. One change that might leave you scratching your head is the addition of new and changed terms for some familiar components. We also have a couple new components, so those might be unfamiliar too. Let's take a quick walk through the changed terms to get you started.
The first thing that you'll notice is an emphasis on capabilities rather than product names. You might not see these familiar product names anymore:
InfoSphere MDM Server
Initiate Master Data Service (MDS)
Other Initiate product names
Instead, you’ll see references to technical capabilities that those products achieve:
You might be wondering what exactly these technical capability terms mean. You can use virtual, physical, and hybrid MDM to manage your master data, whether you store that data in a distributed fashion, in a centralized repository, or in a combination of both.
The following definitions show the differences and the relationships among the technical capabilities:
The management of master data where master data is created in a distributed fashion on source systems and remains fragmented across those systems with a central "indexing" service.
The management of master data where master data is created in (or loaded into), stored in, and accessed from a central system.
The management of master data where a coexistence implementation style combines physical and virtual technologies.
Server and engine terms
Another new area that you’ll notice is a unified server, which is referred to by one common term:
The former InfoSphere MDM Server and the former Initiate Master Data Service are combined to share a single infrastructure in the application server. That single infrastructure is called the MDM operational server or operational server for short. The operational server is the software that provides services for managing and taking action on master data. The operational server includes the data models, business rules, and functions that support entity management, security, auditing, and event detection. For detailed descriptions and diagrams, see the arch
Records, member records, and entities
Finally, the concepts of entities and records were clarified:
A single unique object in the real world that is being mastered. Examples of an entity are a single person, single product, or single organization.
The storage representation of a row of data.
The representation of the entity as it is stored in individual source systems. Information for each member record is stored as a single record or a group of records across related database tables
Depending on your implementation style, these concepts reflect the technical capabilities of virtual, physical, and hybrid MDM. For example, an entity in virtual MDM is assembled dynamically based on the member records by using linkages and then is stored in the MDM database. Conversely, an entity in physical MDM is based on matching records from the source systems that are merged to form the single entity. For details, see the diag
I’ll leave a discussion of hybrid MDM to a future article. If you’d like to read some conceptual topics about hybrid MDM now, see its technical overview.

Skip the fluff and go deep into the technical details of InfoSphere MDM. In a series we're calling MDM Tech TV, several IBM engineers catch you up on technical topics. These informal video demonstrations give you a quick taste of various features.
The three new videos complement the existing MDM videos:

You must have faced quite a good amount of code generation issues if you are working on MDM Server v8 or v8.5. One of the main problems that I have faced was whenever we do not have a hold on the OOTB code generation technique. Say if you need to have OOTB TCRM
Errors logged during code generation
Errors occurred during execution
Error executing tag handler: java
Another problem which we face is, MDM does not support the Transient Object code generation in v8 or 8.5 Hence we have land up with no other option other than to create an Entity, its corresponding classes and will not be persisted. It would be used as a wrapper object. Therefore, your project may have unnecessary files which you may not use in MDM framework.
By this approach it helps the developer to have a strong hold on how your service description should be by writing your own WSDL and generating the java code based on the definition in the WSDL. Definitely, this approach would be challenging as it will not be as simple as clicking the Generate Code in the MDM Model Editor
RAD : 22.214.171.124
MDM : MDM Server v 8.5
WAS : v6.1
Creating Top-Down Web Service
Web services can be created using two methods: top-down development and bottom-up development. Top-down Web services development involves creating a Web service from a WSDL file.
When creating a Web service using a top-down approach, first you design the implementation of the Web service by creating a WSDL file. You can do this using the WSDL Editor. You can then use the Web services wizard to create the Web service and skeleton Java™ classes to which you can add the required code.
Although bottom-up Web service development may be faster and easier, the top-down approach is the recommended way of creating a Web service. By creating the WSDL file first you will ultimately have more control over the Web service, and can eliminate interoperability issues that may arise when creating a Web service using the bottom-up method.
The tools that help to generate the web service artifacts are WSDL2JAVA.bat and JAVA2WSDL.bat.
WSDL2JAVA generates the web service skeletons and the deployment descriptor templates against a WSDL. This is used for the top down approach
JAVA2WSDL generates WSDL from the Java class. This is used for bottom up approach.
This document helps you to create a top to down EJB implementation of Web Service for MDM services. It is quite simple to develop a web service with the help of Web Service editor that is available with the RAD.
By the end of this document, you will be able to create an ejb web service implementation from WSDL to invoke MDM services.
Note: We need to have manual effort to bring up the web service project structure in sync with the classes and the class names that gets generated with the help of MDM model editor.
RAD Preference Settings
Prior to developing the Web Service, you need to set certain Preferences in RAD.
1. Windows > Preferences > Web Services > Resource Management
Note: It is a good practice to select this option when you use utility JAR files or third party libraries, in order to avoid these loadable Java Classes that have to be regenerated.
Below are the steps which explain how to create a top down EJB web service implementation:-
Click Next > Generates the Web Service skeleton from the WSDL and publishes the project to the server
Note:- Start the server before generating the web service
i. Move the SearchBindingImpl to Proj
ii. Rename the below files:-
SearchBindingImpl -> SearchServiceBean
iii. ejb-jar.xml ->
a) Modify the mapping of
ix. If you have defined wrapper object in WSDL to hold any OOTB objects, make sure you create the BObj, Converter and Constructor for the same.

Before the MDM Developers group got going a few authors from the IBM development team posted on the MDM Workbench blog. Now that this group blog has a few posts as well it makes sense to combine the two, so we won't be posting to the separate MDM Workbench blog in the future.
This blog is for more than just the workbench but the biggest advantage is that it is much easier for anyone to contribute: any member of the group can write a blog post! If you have something to share that you think the community would find useful, give it a try. It's a great way to get early feedback on something that may turn in to a full developerWorks article over time. If you do write a post, just let me know as soon as you are ready for it to be published.
These are just a selection of some of the popular posts from the old blog:
And don't forget, there are still forums available for questions and discussions:

No results found is a common response to a search request, but how do you detect this in your BPM process ?
A “No Results Found” situation causes an exception to be thrown which means you can detect it using an intermediate error event, but you need to be able to handle a real errors as well as a no results found which is a special kind of exception.
Here we have a simple example of a search human service which applies equally to Physical and Virtual MDM Server.
There is an intermediate error event attached to the do search nested service that calls the MDM Search integration service. The gateway decision determines whether it is a no results found or not.
To determine how to configure the decision gateway we need to have a look at the format of the exception we get when a no results found is generated and this differs slightly between virtual and physical MDM Server.
Handling a Virtual MDM Server response
A sample of part of the xml format of the exception is shown here
Here is is the reason code we are interested in. So the decision gateway configuration looks like this
The decision logic being
extracts the reason code and checks for ENOREC.
Handling Physical MDM Response
The implementation remains the same, the test within the decision gateway needs to be altered as the location of the reason code is different to virtual. In this example the reason code that is checked is applicable to a Party or Person Search, however it is possible that the reason code will be different for different types of physical search.
A sample of part of the xml format of the exception is shown here
Here we see the reason code we are interested in is nested under the <errors> tag within an < element>.
So in this case we need the decision logic to be

The team here are pleased to announce that after many nights researching, writing and editing, a new IBM Redbook is due to be published entitled 'Designing and Operating a Data Reservoir'.
The book takes you through the steps an organization should go through when designing and building a data reservoir solution, In this book we base the scenario around a pharmaceutical company, however the discussions, principals and patterns included in the book are relevant for any industry.
A data reservoir provides a platform to share trusted, governed data across an organization. It empowers users to engage in the sharing and reuse of data to ensure that an organization can fully leverage their most important asset. - Data. A data reservoir allows for collection of vast sets of data that can be curated, shaped and monitored to allow advanced analytics to be constructed offering new insights to an organization about their data.
See this blog post for more background on the need for a data reservoir:
The new IBM Redbook, as been authored by thought leaders in the data management space and will be available as a full IBM Redbook publication shortly. In the mean time the draft is available directly from the IBM Redbooks website:
We'd love to hear your feedback on the book and would be keen to hear your stories around data reservoir solutions.
