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.

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.

Representing a continued expansion of its big data analytics portfolio, IBM has introduced a new addition to the Netezza product family of analytics appliances that is designed to help organizations uncover patterns and trends from extremely large data sets. The appliance is the first to be delivered by IBM since it acquired Netezza in November 2010. According to IBM, using the new appliance, businesses can now more easily sift through petabytes of data, including banking and mobile phone transactions, insurance claims, electronic medical records, and sales information, and they can also analyze this information to reveal new trends on consumer sentiment, product safety, and sales and marketing effectiveness. "This new appliance takes the scalability to a completely new dimension," says Razi Raziuddin, senior director of product management at IBM Netezza.

When you think of mission-critical services, perhaps none is as critical as electrical service. Not much can happen in modern businesses, government offices, or even homes without it. Central Vermont Public Service (CVPS) is the largest electric company in Vermont. More than 159,000 customers in 163 communities rely on the electrical service CVPS provides. And, according to J.D. Power and Associates, a global marketing and surveying company, for overall customer satisfaction, CVPS continues to rank in the top tier of utilities in the eastern region, more than 50 points above the regional average.

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.

Through the many changes in IT over the years, one constant has always been a concern for performance. With database systems there is especially true. Even with the many advances in relational database technology, SQL performance still remains a key concern for IT professionals and management. Writing SQL for performance is one of the single biggest opportunities for professionals to contribute efficient, effective, cost saving deliverables to projects. Writing SQL for performance can also avoid having to respond to an urgent problem with performance in a production environment. To a considerable extent, a person can choose whether they are running because it is lunch or whether they are running because they are lunch, by following a few simple techniques for writing SQL for performance.

Design reviews are an important facet of the system development lifecycle for database applications. It is during the design review that all aspects of the database and application code are reviewed for efficiency, effectiveness, and accuracy. It is imperative that all database applications, regardless of their size, are reviewed to assure that the application was design properly, efficient coding techniques were used, and the database is accessed and modified correctly and efficiently. The design review is an important process for checking the validity of design decisions and correcting errors before applications and databases are promoted to production status.

Tables within a database management system (DBMS) need primary keys and defined indexes in order for the DBMS to have the opportunity to provide good query performance. Without indexing, the worst possible query performance is guaranteed. The content of these non-keyed tables remains unknown to the DBMS, a black box, where the only possible approach for query execution is to read every row one-by-one. Under such scenarios, the DBMS is little more than a file server that operates more slowly than usual. Without the primary key and indexing, the DBMS may expend even more processor cycles in moving data in and out of the DBMS proprietary storage areas than a file server uses in opening files.

I have been working with SQL Server for more than 10 years now, and my time with Quest has been spent as a consultant visiting hundreds of customer sites, and discussing their environments and matching products to their issues. This has given me a fairly unique insight into how SQL Server is changing. It has also been intriguing to work closely with colleagues from the Oracle world, and seeing how their opinion of SQL Server has changed. They now take it very seriously, something I like to think I have played a positive part in! The most striking trend I have noticed is the lack of expertise in some environments when using SQL Server. I can confidently say you are extremely unlikely to run an Oracle database without an Oracle DBA. However, in the SQL Server world this practice seems to be commonplace.
