Use BizTalk XML Polling to Pull SQL Server Generated XML

Introduction
BizTalk has long been one of the most complex and powerful integration platforms out there. With BizTalk, developers and business users alike have been able to create powerful inter-organizational integrations to automate complex business processes. While most BizTalk developers should be familiar with the basic features of the core BizTalk components such as schemas, maps, orchestrations, pipelines, and receive/send ports the same cannot be said for some of the more hidden and/or complex features. If used properly these features can greatly reduce the amount of development overhead for more complex integrations. One of these features is the XmlPolling option in the WCF-SQL receive configurations.

X12 EDI Databases for HIPAA Transactions

The X12 HIPAA transaction set is used across the healthcare industry to transmit claim, enrollment and payment information. Given the importance and ubiquity of these EDI files, you might assume that translating them from ANSI to a relational database format would be well-supported with a range of options.
In practice, a task as common as parsing a claim or encounter and storing it in a database can quickly escalate into a significant problem.
One solution we’ve seen involves archiving a snapshot of the EDI file using filestream storage. This can satisfy some retention requirements, but provides little in terms of fine-grained tracking or analytic capabilities.
A more complete approach is to parse the X12 file into its discrete elements and store them in a relational database. The ideal solution captures the full extent of the EDI transactions while also applying a reasonable leveling of flattening to keep in the number of table joins under control.

Data Virtualization: Unlocking Data for AI and Machine Learning

For reliability, accuracy and performance, both AI and machine learning heavily rely on large sets. Because the larger the pool of data, the better you can train the models. That’s why it’s critical for big data platforms to efficiently work with different data streams and systems, regardless of the structure of the data (or lack thereof), data velocity or volume.
However, that’s easier said than done.
Today every big data platform faces these systemic challenges:

Compute / Storage Overlap: Traditionally, compute and storage were never delineated. As data volumes grew, you had to invest in compute as well as storage.
Non-Uniform Access of Data: Over the years, too much dependency on business operations and applications have led companies to acquire, ingest and store data in different physical systems like file systems, databases and data warehouses (e.g. SQL Server or Oracle), big data systems (e.g….

Keeping Freight Moving in Denmark with SQL Server 2016

Efficient data management keeps goods flowing smoothly in Denmark. Danske Fragtmaend, the country’s largest national transport and distribution firm, has been moving freight for more than a century. Today, Danske Fragtmaend delivers more than 40,000 consignments each day throughout Denmark, and businesses from small mom-and-pop operations to factories rely on its services.
The firm handles logistics in a central location, where 200 dispatchers keep an eye on the movement of thousands of trucks and their cargo. Both drivers and dispatchers need the latest information to operate efficiently, so they rely on a data platform based on SQL Server 2016. The storage system includes 160 terabytes of flash memory for fast I/O and high uptimes. Throughout the day, drivers continually scan transactions with PDAs and send shipping information including GPS coordinates to the data platform. Fast access to information is essential. Ulf…

Using T4 Templates to Generate C# Enums from SQL Server Database Tables

When building applications with C# and SQL Server, it is often necessary to define codes in the database that correspond with enums in the application. However, it can be burdensome to maintain the enums manually, as codes are added, modified, and deleted in the database.
In this blog post, I’ll share a T4 template that I wrote which does this automatically. I looked online first, and did find a few different solutions for this, but none that worked for me as-is. So, I built this generic T4 template to do the job, and you can use it too.
Let’s say you’ve got a Color table and ErrorType table in the database, populated as follows:

Now you’d like enums in your C# application that correspond to these rows. The T4 template will generate them as follows:

Before showing the code that generates this, let’s point…

The Top 5 Reasons to Upgrade to SQL Server 2016

Upgrading your software can be daunting, Microsoft knows. The fast pace of business makes it easy to tell yourself, “I’ll do it later when I have time.” Microsoft gets it! But here are five key reasons to make time to upgrade to SQL Server 2016, which was named DBMS of the Year in 2016 by DBengines.com.

Seamless step-up without rewriting apps. Thanks to November’s SQL Server 2016 Service Pack 1 (SP1), SQL Server now has one programming surface across all editions. If you switch from Express to Standard, or Standard to Enterprise, you don’t have to rework code to take advantage of additional features. Time saved! In addition, the change brings access to innovative features across performance, security, and analytics not previously available in Express or Standard—a great reason to upgrade applications that run on those editions. The Enterprise edition of…

Part 2 – Analysis Services Multidimensional: “A Duplicate Attribute Key Has Been Found When Processing”

Introduction – Part 2

Part 1 of this post focused on the first category of how the Analysis Services Multidimensional (MD) duplicate attribute key error can arise. It reflects the perspective of an atomic attribute – an attribute having no attribute relationships other than with the dimension key attribute.
This post focuses on the second category of this error, which can arise when an attribute does have attribute relationships besides the (required) one with the dimension key attribute.
As is well known, creating attribute relationships is a best practice in Analysis Services MD for improving query performance. The most common reason attribute relationships are created is to support a natural hierarchy – so your data model has to have one for this to arise. The next most common reason is to support attribute properties, such as a sort order – i.e. when the…

Microsoft’s SQL Platform Continues to Lead the Market with Advanced Data Security

Securing customer data while maintaining the highest levels of privacy have always been top priorities for Microsoft and the SQL organization. As a result, SQL Server, which also powers Azure SQL Database and Azure SQL Data Warehouse, continues to be one of the most secure Relational Database Management Systems (RDBMS) on the market.[1]
At the RSA Conference last year, Microsoft talked about their commitment to security and privacy. Microsoft wants to share a few examples of industry-leading security features they shipped since then and update you on their plans to deliver the highest levels of security across the SQL Database product lineup.
Announcing the April general availability of Azure SQL Database Threat Detection for proactive monitoring and alerting of suspicious database activities and potential vulnerabilities.
Using machine learning, SQL Database Threat Detection continuously monitors and profiles application behavior, and detects suspicious database activities…

Fixing SQL Server 2012 Support for Custom SSIS Objects in Visual Studio 2015+

You’re using the new One Designer cross-versioning in SQL Server Integration Services, and everything breaks when you try to downgrade to SQL Server 2012. The little icon that indicates that everything has gone wrong shows up,
or when you try to interact with any custom components or tasks you get the following error, or something similar:

 
Now, there are three things worth checking:

Are your UpgradeMapping files set up correctly? They should point to a valid strong-named assembly, and use the same alias, for both versions of SQL Server that you’re attempting to deploy to. If not, fix this issue first and try again.
After migrating your custom objects, navigate to the UserComponentTypeName property (for PipelineComponents) or to the CreationName field of the corresponding DTS:Executable in the package XML.

These should contain either the alias (typically the qualified name of the class, i.e. Sample.SSIS.CustomTask),
or the strong-name associated with…

Analysis Services Tabular: Many-To-Many Relationships, Bridge Tables, and Blank Members

With bidirectional filtering in SQL Server Analysis Services (SSAS) Tabular 2016, it’s easier than ever to build many-to-many relationships into your model. But what are some ways to avoid trouble when building them? This post covers two topics: (1) a scenario that can cause Tabular to match completely unrelated groups across a many-to-many relationship, and (2) some strategies for automating your bridge tables (including where they might need some brains!). If you’re already comfortable with this topic, and just want to see some DAX, feel free to skip right to the calculated bridge tables.
Otherwise, let’s say you’ve built up your many-to-many relationship based on a bridge or relationship table someone generated in the database, and have measures based on one or both of the tables connected by the bridge. When looking at the results, you see that a number of the results…
