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.

There is no doubt that virtualization is radically changing the shape of IT infrastructure, transforming the way applications are deployed and services delivered. Databases are among the last of the tier 1 applications to be hosted on virtual servers, but the past year has seen a huge wave of increase for production Oracle, SQL Server and other databases on VMware platforms. For all the benefits of virtualization, including cost-effectiveness, there are some impacts on the IT staff involved. Unfortunately for the DBAs virtualization often means losing control and visibility of their systems, which can ultimately hinder their ability to deliver database-oriented business solutions. While in the past DBAs had perfect visibility to the physical servers hosting the databases, the virtualization layers and the tools to manage them are typically out of bounds to them. While all the excitement of late has centered on VMware and other virtual machine systems, the DBAs have a valid reason for skepticism.

Given all of the recent discussion around big data, NoSQL and NewSQL, this is a good opportunity to visit a topic I believe will be (or should be) forefront in our minds for the next several years - high velocity transactional systems. Let's start with a description of the problem. High velocity transactional applications have input streams that can reach millions of database operations per second under load. To complicate the problem, many of these systems simply cannot tolerate data inconsistencies.

By implementing a business analytics information platform that allows sharing of computing and data resources through the new Sybase IQ PlexQ technology, the company says enterprises can break down user and information silos to increase analytics adoption throughout their entire organization. There is a lot of talk about big data, but how to manage it and analyze it is only half the problem, observes David Jonker, senior product marketing manager of Sybase IQ. "The other half is how do you make it more pervasive throughout the enterprise and from our perspective that is where a lot of the existing data warehousing solutions fall down."

Naïve approaches to business intelligence will occasionally trap designers as they juggle operational data stores and data warehouses. The trap results from an honest endeavor to simplify designs and increase consistency throughout the solution. Under the umbrella of consistency a designer may plan for a reference table used for operational look-ups to perform a second service as a star schema dimensional table. Some or all reference tables then are declared by fiat to also be dimensions. While on a superficial level there are similarities between dimension tables and more normalized look up or reference tables, fundamentally these two concepts are separate things.

Like most people, I chuckled under my breath when doomsayers started publishing books about the apocalypse predicted by their interpretation of the Mayan calendar. In their view, the Mayan calendar ends in 2012 and thus spells doom for us all - despite the fact that the classical Mayan calendar, like ours today, was cyclical. But as I was considering some of the momentous and disruptive changes we're facing lately, it suddenly hit me. The year 2012 might be the year when life as we've known it as IT and data professionals changes, completely and irrevocably

Simplification is important in today's era of increasing complexity and ever-changing software environments. A key component of simplification is to remember the basics and apply some elementary rules and practices to your database environment. Many problems arise because we don't keep track of the things most of us already know. I stumbled upon the idea for this month's column after recalling Malcolm Gladwell's excellent business book Blink: The Power of Thinking Without Thinking. In this book, Gladwell offers up case studies and examples depicting the benefit of our "adaptive unconscious" - a powerful innate ability that provides us with instant and sophisticated information.

Time series data is a sequence of data points typically measured at successive times and may be spaced at uniform time intervals. Time-stamped data can be analyzed to extract meaningful statistics or other characteristics of the data. It can also be used to forecast future events based on known past events. Time series data enables applications such as economic forecasting, census analysis and forecasting, fleet management, stock market analysis, and smart energy metering. Because it is time-stamped, time series data has a special internal structure that differs from relational data. Additionally, many applications such as smart metering store data at frequent intervals that require massive storage capacity. For these reasons, it is not sufficient to manage time series information using the traditional relational approach of storing one row for each time series entry.

Today, we operate in a global economy at internet speed. Globalization of our workforce has shifted the way work gets done. The explosion of wireless and edge technology has raised the expectations of consumers, who are more informed, educated, and knowledgeable about products and services. This changing landscape places immense pressure on business applications in organizations worldwide. Critical application outages caused by software defects can cost the business millions of dollars in revenue for every hour of downtime.

As the economy shifts to expansion mode, and businesses start hiring again, a familiar challenge is rearing its head. Companies are scrambling to find the talent needed to effectively run, maintain, and expand their technology platforms. This is not a new problem by any means, but this time around, it is taking on a greater urgency, as just about every organization relies on information technology to be competitive and responsive to growth opportunities. A new survey of 376 employers finds a majority depend on the educational sector - universities and colleges - to provide key IT skills, often in conjunction with their own internal training efforts. However, few of the executives and managers hiring out of colleges are entirely satisfied with the readiness of graduates.

Is the day of reckoning for big data upon us? To many observers, the growth in data is nothing short of incomprehensible. Data is streaming into, out of, and through enterprises from a dizzying array of sources-transactions, remote devices, partner sites, websites, and nonstop user-generated content. Not only are the data stores resulting from this information driving databases to scale into the terabyte and petabyte range, but they occur in an unfathomable range of formats as well, from traditional structured, relational data to message documents, graphics, videos, and audio files.

One of the things I repeatedly encounter when speaking to database professionals working with Microsoft SQL Server is that many of them simply don't know about some of the most elementary and fundamental means of investigating SQL Server performance. For example, I recently created a popular poster for Quest Software that shows all of the most meaningful and useful Windows Performance Monitor (PerfMon) counters. Now friends, PerfMon has been with us since Windows NT Server, and yet, PerfMon counters are a mystery to at least half of the DBAs I meet. Half!

I just got back from the very well done 2011 MySQL Conference put on by O'Reilly out in Santa Clara, California. I believe this was my sixth time at the MySQL show, although this year it was somewhat of a different experience for me. This time, instead of representing the MySQL band of merry men (and women), being that I am now at EnterpriseDB, I was promoting PostgreSQL. In fact, if you want to hear something really strange: EnterpriseDB was the only diamond sponsor of the event. A PostgreSQL vendor? The diamond sponsor at a software show catering primarily to MySQL professionals? What gives?

The DBA, often respected as a database guru, is just as frequently criticized as a curmudgeon with technical knowledge but limited people skills. Most programmers have their favorite DBA story. You know, those anecdotes that begin with "I had a problem ..." and end with "... and then he told me to stop bothering him and read the manual." DBAs do not have a warm and fuzzy image. This may have something to do with the nature and scope of the job. The DBMS spans the enterprise, effectively placing the DBA on call for the applications of the entire organization. Database issues can require periods of quiet reflection and analysis to resolve, so DBAs generally do not want to be disturbed. But their quiet time is usually less than quiet; constant interruptions to answer questions and solve problems are a daily fact of life.

Occasionally, one sees a data structure abomination. This atrocity involves an object of almost any type, in almost any database wherein the object has a start date but no end date. It is not that the finish date currently has no value and is null; it is that the end date does not even exist on the table structure. The stop date was never intended to exist. The object in question starts, but it doesn't ever end.
