Database Management

Relational Database Management Systems (RDBMSs) continue to do the heavy lifting in data management, while newer database management systems are taking on prominent roles as well. NoSQL database systems such as Key-Value, Column Family, Graph, and Document databases, are gaining acceptance due to their ability to handle unstructured and semi-structured data. MultiValue, sometimes called the fifth NoSQL database, is also a well-established database management technology which continues to evolve to address new enterprise requirements.

Four top Microsoft SQL Server executives will present keynote addresses at the Professional Association for SQL Server's PASS Summit Unite 2009 conference, Nov. 2-5.

There are mainly four kinds of information management professionals in an OLTP environment—data architects, database architects, application DBAs and operational (or production support) DBAs. It should be the aim of an information management professional to master all the four roles and seamlessly shift between them with ease. Once you are able to shift roles easily, be assured that you're adding to the revenue of your business.

The data manager's job has never been easy, often presenting significant challenges, including data system rewrites, data security, regulatory compliance, and reporting. And the digital age, with a myriad of new and innovative data sources and more sophisticated analytic models, presents its own unique hurdles to implementing a successful data-management and data-quality program in the modern insurance enterprise.

New data modelers often see things as black and white. But rather than being concrete flooring beneath our feet, knowledge is more like a gossamer web that builds up layer upon layer to provide the effect of a solid foundation. We may think we know facts, such as one plus one equals two, or Columbus discovered America in 1492. What we have come to know about our world comprises our own internal knowledge base. We gain much of this knowledge because it has been passed onto us by others, people with experience, parents, educators, clever friends, verbally or in print. But how do we know such items are real, actual, absolute bona fide beyond-a-shadow-of-a-doubt truths?

Microsoft SQL Server's relational engine has offered new instrumentation that improves by light years with each new release. The introduction of Dynamic Management Views (DMVs) in SQL Server 2005 provided a much-needed equivalent to Oracle's long-standing and capable V$ and X$ system views. SQL Server 2008 has provided another dramatic improvement to its instrumentation with Extended Events (also known as XEvents) that promises to offer even greater opportunities to tune, trace and troubleshoot the inner workings of a SQL Server application. All of this stands in stark contrast with the anemic instrumentation offered in SQL Server Analysis Services, Microsoft's wonderful multi-dimensional data repository that is a free feature-set within the SQL Server product.

As the U.S. markets strive for a recovery in 2009, many IT managers are cringing at the thought of managing their data through what may be a record year of mergers and acquisitions. Managing an ever-increasing mountain of data is not a simple task in the best of times, but doing so while combining formerly separate entities during an economic slowdown can be a monumental challenge.

While good database design is always necessary, the value of good design is reinforced by such endeavors as service-oriented architecture. The semantics-laden engineering of service-oriented tactics used in creating solutions melds seamlessly into the semantics-laden world of data modeling. Although one aspect does not necessarily build on top of the other, each works as part of a team in braiding solutions that grow in usefulness as they emerge. The processes surface as a method to further define the meaning of an object, and the object serves as a harbinger of the processes that must exist. Business rules much more advanced than today's simple constraints may one day reside within the database itself as a built-in function of a some future DBMS. Therefore, data architects should never try to wall themselves behind a veneer of thinking only in terms of data without a thought regarding the processes that touch the data. As a database designer, working within projects that use service-oriented architecture approaches can be exhilarating.

Protecting the data in our enterprise databases is extremely important. But what exactly does that mean? Oh, at one level we have the database authorization and roles built directly into the DBMS products. You know what I'm talking about: GRANT and REVOKE statements that can be used to authorize access to database objects, resources and statements. Many organizations have adopted policies and products to migrate this type of security out of the DBMS and into their operating system security software.

At a rather muted Microsoft TechEd in Los Angeles in May, the crowds were diminished and the educational content was slimmed down. In the past, SQL Server sessions were so abundant that you'd have trouble choosing which of several you might want to attend. This year, the state of the economy was reflected in many ways, including the one, or, in just a few cases, two sessions per time slot allotted SQL Server professionals. Despite the low ebb, the Microsoft SQL Server team made an exciting announcement about the upcoming availability of the SQL Server 2008 R2 CTP (Community Technology Preview).

Before we even begin this month's column I had better define what I mean by a "black box." Simply put, a black box is a database access program that sits in-between your application programs and the DBMS. It is designed so that all application programs call the black box for data instead of writing SQL statements that are embedded into a program. The general idea behind such a contraption is that it will simplify application development because programmers will not need to know how to write SQL. Instead, programmers call the black box to request data. SQL statements become calls-and every programmer knows how to code a call, right?

While setting up a replication configuration, in which changes from a production or primary system are propagated to a standby or secondary system, is a fairly standard way to enable disaster recovery (DR) for business-critical databases, one of the important technology decisions that organizations must make upfront is the choice of the replication architecture, writes Ashish Ray, director of product management, high availability, at Oracle, in the current e-edition of Database Trends and Applications.

An inherent awkwardness exists in every many-to-many relationship between entities. Ambiguity causes this persistent awkwardness, primarily because a many-to-many relationship is such a fuzzy thing. In data discovery, encountering many-to-many relationships may actually expose a level of disregard about details by the subject matter experts.

The economy is a wreck and things will likely get worse before they improve. Unemployment is even worse; almost 600,000 jobs were lost in January 2009, sending the unemployment rate to 7.6%, the highest it has been in 16 years. So many data professionals are out there looking for their next challenge … and more probably will be job hunting before the year is out.
