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.

Two columns ago, I described how the TPC benchmarks are useful for getting a general idea of the performance characteristics of your preferred database vendor and hardware platform. And in last month's column, I described how the published TPC benchmarks can even help with pricing, especially when you don't have your own quantity discounts in place.

Two big questions are on the minds of data professionals these days. How are increasing complexity and the inevitable onslaught of big data shaping the future of database administrators and data architects? How will our roles change? In the interest of studying the evolving landscape of data, the Independent Oracle User's Group (IOUG) took the pulse of the community. The Big Data Skills for Success study polled numerous individuals in the IOUG Oracle technology community, to identify just how the responsibilities of handling data are changing and what the future of these roles looks like.

When data professionals think about regulatory compliance we tend to consider only data in our production databases. After all, it is this data that runs our business and that must be protected. So we work to implement database auditing to know who did what to which data when; or we tackle database security and data protection initiatives to protect our data from prying eyes; or we focus on improving data quality to ensure the accuracy of our processes.

Databases are restricted by reliance on disk-based storage, a technology that has been in place for several decades. Even with the addition of memory caches and solid state drives, the model of relying on repeated access to information storage devices remains a hindrance in capitalizing on today's "big data," according to a new survey of 323 data managers and professionals who are part of the Independent Oracle Users Group (IOUG). The survey was underwritten by SAP Corp. and conducted by Unisphere Research, a division of Information Today, Inc.

A profound shift is occurring in where data lives. Thanks to skyrocketing demand for real-time access to huge volumes of data—big data—technology architects are increasingly moving data out of slow, disk-bound legacy databases and into large, distributed stores of ultra-fast machine memory. The plummeting price of RAM, along with advanced solutions for managing and monitoring distributed in-memory data, mean there are no longer good excuses to make customers, colleagues, and partners wait the seconds—or sometimes hours—it can take your applications to get data out of disk-bound databases. With in-memory, microseconds are the new seconds.

EMC Corporation has updated its appliance-based unified big data analytics offering. The new EMC Greenplum Data Computing Appliance (DCA) Unified Analytics Platform (UAP) Edition expands the system's analytics capabilities and solution flexibility, achieves performance gains in data loading and scanning, and adds integration with EMC's Isilon scale-out NAS storage for enterprise-class data protection and availability. Within a single appliance, the DCA integrates Greenplum Databases for analytics-optimized SQL, Greenplum HD for Hadoop-based processing as well as Greenplum partner business intelligence, ETL, and analytics applications. The appliances have been able to host both a relational database and Hadoop for some time now, Bill Jacobs director of product marketing for EMC Greenplum, tells 5 Minute Briefing. "The significance of this launch is that we tightened that integration up even more. We make those two components directly manageable with a single administrative interface and also tighten up the security. All of that is targeted at giving enterprise customers what they need in order to use Hadoop in very mission-critical applications without having to build it all up in Hadoop themselves."

Today's data warehouse environments are not keeping up with the explosive growth of data volume (or "big data") and the demand for real-time analytics. Fewer than one out of 10 respondents to a new survey say their data warehouse sites can deliver analysis in what they would consider a real-time timeframe. Nearly 75% of respondents believe that in-memory technology is important to enabling their organization to remain competitive in the future. Yet, almost as many also indicate they lack the in-memory skills to deliver even current business requirements. These are among the findings of a new survey of 323 data managers and professionals who are part of the Independent Oracle Users Group (IOUG). The survey was underwritten by SAP Corporation and conducted by Unisphere Research, a division of Information Today, Inc.

Let's talk about database application benchmarking. This is a skill set which, in my opinion, is one of the major differentiators between a journeyman-level DBA and a true master of the trade. In this article, I'll be giving you a brief introduction to TPC benchmarks and, in future articles, I'll be telling you how to extract specific tidbits of very valuable information from the published benchmark results. But let's get started with an overview.

Within the information technology sector, the term architect gets thrown around quite a lot. There are software architects, infrastructure architects, application architects, business intelligence architects, data architects, information architects, and more. It seems as if any area may include someone with an "architect"status. Certainly when laying out plans for a physical building, an architect has a specific meaning and role. But within IT "architect" is used in a much fuzzier manner.

Not long in the past, SQL Server licensing was an easy and straightforward process. You used to take one of a few paths to get your SQL Server licenses. The first and easiest path was to buy your SQL Server license with your hardware. Want to buy a HP Proliant DL380 for a SQL Server application? Why not get your SQL Server Enterprise Edition license with it at the same time? Just pay the hardware vendor for the whole stack, from the bare metal all the way through to the Microsoft OS and SQL Server.

A proper database design cannot be thrown together quickly by novices. A practiced and formal approach to gathering data requirements and modeling data is mandatory. This modeling effort requires a formal approach to the discovery and identification of entities and data elements. Data normalization is a big part of data modeling and database design. A normalized data model reduces data redundancy and inconsistencies by ensuring that the data elements are designed appropriately.
