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.

Lectures related to master data bring forth all sorts of taxonomies intended to help clarify master data and its place within an organization. Sliding scales may be presented: at the top, not master data; at the bottom, very much master data; in the middle, increasing degrees of "master data-ness." For the longest of times everyone thought metadata was confusing enough ... oops, we've done it again. And, we have accomplished the establishment of this master data semantic monster in quite a grand fashion.

Many types of data change over time, and different users and applications have requirements to access data at different points in time. A traditional DBMS stores data that is implied to be valid at the current point-in-time, it does not track the past or future states of the data. For some, the current, up-to-date values for the data are sufficient. But for others, accessing earlier versions of the data is needed. Temporal support makes it possible to store different database states and to query the data "as of" those different states.

"Big data" and analytics have become the rage within the executive suite. The promise is immense - harness all the available information within the enterprise, regardless of data model or source, and mine it for insights that can't be seen any other way. In short, senior managers become more effective at business planning, spotting emerging trends and opportunities and anticipating crises because they have the means to see both the metaphorical trees and the forest at the same time. However, big data technologies don't come without a cost.

Let's tie together the last several columns on "2012 Might Really be The End of the World." In this series, I discussed several megatrends in the general IT industry that will have a tremendous impact on the database administration (DBA) profession. The megatrends include both software-related (virtualization and cheap cloud database services) and hardware-related (SSDs and massively multi-core CPUs). These technologies have the potential to obviate many of the core competencies of the DBA, with the first two eliminating or lessening the need for server and hardware configuration and provisioning, and the last two diminishing the need for IO tuning and query tuning, respectively. But those are trends that will take years to reach fruition. What about the near future?

Along with thousands of IT professionals, I was in the San Francisco Moscone Center main hall last October listening to Larry Ellison's 2011 Oracle Open world keynote. Larry can always be relied upon to give an entertaining presentation, a unique blend of both technology insights and amusingly disparaging remarks about competitors.

Retaining the particulars of change over time is a fairly intricate configuration. Audit log or shadow tables are sometimes employed, but on occasion there is a need for the "old" and "new" rows to exist in a single operation table for application use. Far too often, the implementation of temporal data structures is shoddy, loose, and imprecise; rather than the fairly complex dance move such temporal arrangements must perform in actuality. The sub-optimal result is much like one's performance of the Funky Chicken at a friend's wedding; the desired moves are mimicked, after a fashion, but it is unlikely to earn high marks on "So You Think You Can Dance." The usual temporal implementation simply slaps on start and stop dates, debates a little over default date values versus NULLs, then moves on to the next subject.

At the outset of each new year, I devote an edition of my column to review the significant data and database-related events of the previous year. Of course, to meet my deadlines, the column is written before the year is over (this column is being written in November 2011), so please excuse any significant news that may have happened late in December.

Most Oracle performance analysis is now time-based. But it is "total time"-focused: Time to process a SQL statement, a batch process, or the CPU consumed plus Oracle wait time that occurred over an interval of time. This is a fantastic way to approach optimization because it is easy to monitor improvement and it is closer to what a user is experiencing. And, with just a couple twists, we can unite Operations Research (OR) queuing theory with the Oracle time-based approach, opening up an entirely new arena for performance analysis.

In a world replete with regulations and threats, organizations today have to go well beyond just securing their data. Protecting this most valuable asset means that companies have to perpetually monitor their systems in order to know who did exactly what, when and how - to their data.

The cost for new development can often be easily justified. If a new function is needed, staffing a team to create such functionality and supporting data structures can be quantified and voted up or down by those controlling resources. Money can be found to build those things that move the organization forward; often, the expense may be covered by savings or increased revenue derived from providing the new services.

Being a successful database administrator requires far more than technical acumen and database knowledge. DBAs should be armed with a proper attitude as well as sufficient fortitude and personality before attempting to practice database administration. Gaining the technical know-how is important, yes, but there are many sources that offer technical guidance for DBAs. The non-technical aspects of DBA are just as challenging, though. So with that in mind, this month's column will offer 10 "rules of thumb" for DBAs to follow as they improve their soft skills.

Few things in the world are changing as dramatically as data. Data has tapped out a powerful rhythm to keep time with technology's bleeding edge, leaving many technologies struggling to keep up. It should come as no surprise, then, that many of the data strategies that IT departments developed, and still widely rely upon, are no longer sufficient for today's needs. You can put data marts near the top of that list.

It is not magic. Building a successful IT solution takes time. And that time is used in various ways: obtaining an understanding of the goal; mapping out what components are necessary and how those components interact; testing components and their interaction; and finally migrating those components into the production environment - otherwise known as analysis, design, development, testing, and deployment. Regardless of the methodology employed, these functions must always be addressed. Different approaches focus on differing needs and aspects. But any complete methodology must fill in all the blanks for accomplishing each of these tasks.
