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.

In recent years, the networks of developers, integrators, consultants, and manufacturers committed to supporting database systems have morphed from one-on-one partnerships into huge ecosystems in which they have become interdependent on one another, and are subject to cross-winds of trends and shifts that are shaping their networks. Nowhere is this more apparent than the huge ecosystem that has developed around Oracle. With Oracle's never-ending string of acquisitions, new functionality, and widespread adoption by enterprises, trends that shape this ecosystem are certain to have far-reaching effects on the rest of the IT world. Concerns that percolate through the ecosystem reflect — and influence — broad business concerns. New paradigms — from cloud computing to big data to competing on analytics — are taking root within the Oracle ecosystem long before anywhere else.

Big data is toughfor enterprises to handle, and adding to the challenge is the fact that much of it is unstructured data—business documents, presentations, log files, and social media data. Respondents to a survey of 264 data managers and professionals—subscribers to Database Trends and Applications—almost unanimously agree that unstructured data is on the rise and ready to engulf their current data management systems. The trouble is, their management typically does not understand the scope of the challenge and is failing to recognize the significance of unstructured data assets to the business.

If you've worked with relational database systems for any length of time, you've probably participated in a discussion (argument?) about the topic of this month's column, surrogate keys. A great debate rages within the realm of database developers about the use of "synthetic" keys. And if you've ever Googled the term "surrogate key," you know the hornet's nest of opinions that swirls around on the topic. For those who haven't heard the term, here is my attempt at a quick summary: A surrogate key is a generated unique value that is used as the primary key of a database table; database designers tend to consider surrogate keys when the natural key consists of many columns, is very long, or may need to change.

If you have not heard the buzz around Oracle's Engineered Systems, then you must not be keeping up with Oracle's marketing promotions, reading any technical journals, or even just walking through any airports lately. While the marketing claims are impressive, the use of Marvel's characters was imaginative and Oracle's use of the slogan "Hardware and Software Engineered to Work Together" is enticing, you may be asking yourself, "What does all of this mean to me?" Well, let's illustrate by example.

It is impossible to have missed the sweeping changes being thrust upon the data world due to regulatory compliance. But even if you've noticed, chances are that the sheer volume of regulations was too mind-boggling to fully digest. Compliance starts with the CEO, but it works its way down into the trenches, and impacts database administration. With that in mind, this month's column will offer a brief introduction to the regulatory landscape and its impact on database administration.

SQL Server 2012 includes a lot of new and exciting features. One feature that has caught the imagination of many in the user community is the high-performance feature called Columnstore Indexes. (Incidentally, it was also known as Apollo during its beta cycles). Columnstore indexes, as their name implies, store indexed (and always compressed) data contiguously in columns, rather than in standard format where the data is stored contiguously on 8Kb data pages according to the rows in which the data resides. Because of their structures, columnstore indexes speed up read-heavy operations like data warehouse queries from factors of 10x to 100x.

A database design may occasionally show evidence that it lacks proper prioritization. Data models should express truths about the business, or about the universe of discourse. But in expressing business truth this does not mean a data model should express absolutely every truth that anyone might conceive. Some relationships are significant while other relationships are not. And as a general rule, database design is not an exercise in trivial pursuit. Insignificant truths only clutter up a design, increasing complexity, causing users' eyes to glaze over more quickly, and adding no real value towards the endeavors of the enterprise.

Throughout the 2000s, a huge number of website developers rejected the Enterprise Java or .NET platforms for web development in favor of the "LAMP" stack - Linux, Apache, MySQL and Perl/Python/PHP. Although the LAMP stack was arguably less scalable or powerful than the Java or .NET frameworks, it was typically easier to learn, faster in early stages of development - and definitely cheaper. When enterprise architects designed systems, they often chose commercial application servers and databases (Oracle, Microsoft, IBM). But, when web developers or startups faced these decisions, the LAMP stack was often the default choice.

With the rise of big data,the database and data management tools market is in a state of flux, the likes of which have not been seen in this sector before. Companies are now awash in big data, and end users are demanding greater capability and integration to mine and analyze new sources of information.

Big data is one of the most significant industry disruptors in IT today. Even in its infancy, it has shown significant ROI and has almost universal relevance to a wide cross-section of the industry. Why? Big data turns traditional information architecture on its head, putting into question commonly accepted notions of where and how data should be aggregated, processed, analyzed, and stored. Enter Hadoop and NoSQL, the open source data-crunching platform. Although these technologies are hotter than an Internet IPO, you simply can't ignore your current investments - those investments in SQL which drive everything from your data warehouse to your ERP, CRM, SCM, HCM and custom applications.

In the always-on global economy, access to enterprise data is critical, and interruptions and delays in the flow of information necessary for decision-making can have serious consequences. A new study fielded by Unisphere Research among IOUG members and sponsored by Oracle explores the issues related to planned and unplanned downtime, alongside high availability and disaster recovery solutions. The survey which garnered input from 358 data managers and professionals, finds that at least half of the respondents are working to provide their organizations with real-time or near-real-time data, but the challenge to meeting this goal is increasing as data volumes escalate and the variety and velocity of data heightens as well.
