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.

A new science called "data persona analytics" (DPA) is emerging. DPA is defined as the science of determining the static and dynamic attributes of a given data set so as to construct an optimized infrastructure that manages and monitors data injection, alteration, analysis, storage and protection while facilitating data flow. Each unique set of data both transient and permanent has a descriptive data personality profile which can be determined through analysis using the methodologies of DPA.

Storage Area Networks (SANs) and Network-Attached Storage (NAS) owe their popularity to some compelling advantages in scalability, utilization and data management. But achieving high performance for some applications with a SAN or NAS can come at a premium price. In those database applications where performance is critical, direct-attached storage (DAS) offers a cost-effective high-performance solution. This is true for both dedicated and virtualized servers, and derives from the way high-speed flash memory storage options can be integrated seamlessly into a DAS configuration. There are three primary reasons now for the renewed interest in NAS.

One of the principles within relational theory is that each entity's row or tuple be uniquely identifiable. This means the defined structure includes some combination of attributes whose populated values serve to identify an individual row within the table/relation. This, or these, attribute(s) are the candidate key(s) for the structure. The candidate key is also known as the primary key, or if a structure has multiple candidate keys, then one of them is designated as the primary key. When building up a logical design, primary keys should be identified by the actual data points in play.

Oracle Database 12c is available for download from Oracle Technology Network (OTN). First announced by Oracle CEO Larry Ellison during his keynote at Oracle OpenWorld 2012, Oracle Database 12c introduces a new multi-tenant architecture that simplifies the process of consolidating databases onto the cloud; enabling customers to manage many databases as one - without changing their applications. During the OpenWorld keynote, Ellison described Oracle Database 12c as "the first multi-tenant database in the world" and said it provides "a fundamentally new architecture" to "introduce the notion of a container database" with the ability to plug in multiple separate, private databases into that single container.

In the realm of 21st century data organization, the business function comes first. The form of the data and the tools to manage that data will be created and maintained for the singular purpose of maximizing a business's capability of leveraging its data. Initially, this seems like an obvious statement but when examining the manner in which IT has treated data over the past four decades it becomes painfully obvious that the opposite idea has been predominant.

In the last several articles, I've been describing the benefits of reading and analyzing the benchmarking case studies released by the Transaction Processing Council. I've given you from a broad overview of the TPC benchmarks and shown ways that the vendor-published TPC benchmarks can help you save money and how the vendor-published TPC benchmarks must explain in disclaimers how they tweak their workloads. I have described how to run your own benchmarks and explained how to properly prepare your environment for a benchmark test. Now, it is time to show you where the rubber really hits the road, testing and benchmarking tools that can run highly scalable benchmarking workloads against your database servers.

These are heady times for data products vendors and their enterprise customers. When business leaders talk about success these days, they often are alluding to a new-found appreciation for their data environments. It can even be said that the tech vendors that are making the biggest difference in today's business world are no longer software companies at all; rather, they are "data" companies, with all that implies. Enterprises are reaching out to vendors for help in navigating through the fast-moving, and often unforgiving, digital realm. The data vendors that are leading their respective markets are those that know how to provide the tools, techniques, and hand-holding needed to manage and sift through gigabytes', terabytes', and petabytes' worth of data to extract tiny but valuable nuggets of information to guide business leaders as to what they should do next.

The grain of a fact table is derived by the dimensions with which the fact is associated. For example, should a fact have associations with a Day dimension, a Location dimension, a Customer dimension, and a Product dimension, then the usual assumption would be for the fact to be described as being at a "by Day," "by Location," "by Customer," "by Product" metrics level. Evidence of this specific level of granularity for the fact table is seen by the primary key of the fact being the composite of the Day dimension key, Location dimension key, Customer dimension key, and Product dimension key. However, this granularity and these relationships are easily disrupted.

Although storage management can be an afterthought for the DBA, it really shouldn't be. Storage issues are vitally important and unless managed appropriately, it can be very costly. The cost of managing storage can be as much as 10 times higher than the initial cost of acquiring the storage—and the growth rate for disk storage was 37% between 1996 and 2007. Even so, it is common for storage-related issues to be relegated to the backburner by DBAs, but every database professional should understand modern storage basics.

Over the past year it has been great to see the "Big Data" moniker lose some of its glamour as a catch-all phrase. Fortunately, Hadoop's role is now well understood for processing massive amount of old data for analytics for use cases, which are not sensitive to latency. But, increasing numbers of companies are building new applications that are driving real competitive advantage and disrupting established markets—on the Web, over mobile, or in the Cloud—generating massive amounts of "Big Data." In these new cases, latency matters.
