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.

Oracle OpenWorld, the company's annual Oracle event for business decision-makers, IT management, partners and end users, introduced a flurry of new and updated products and technologies. Here, a round-up of some of the major announcements unveiled at the conference.

Posted September 27, 2013

Oracle CEO Larry Ellison made three key announcements in his opening keynote at Oracle OpenWorld, the company's annual conference for customers and partners in San Francisco. Ellison unveiled the Oracle Database In-Memory Option to Oracle Database 12c which he said speeds up query processing by "orders of magnitude," the M6 Big Memory Machine, and the new Oracle Database Backup Logging Recovery Appliance. Explaining Oracle's goals with the new in-memory option, Ellison noted that in the past there have been row-format databases, and column-format databases that are intended to speed up query processing. "We had a better idea. What if we store data in both formats simultaneously?"

Oracle holds an enviable position in the IT marketplace with a wide array of database systems, development tools, languages, platforms, enterprise applications, and servers. Riding the coattails of this industry giant is a healthy and far-flung ecosystem of software developers, integrators, consultants, and OEMs. These are the partners that will help make or break Oracle's struggle with new forces disrupting the very foundations of IT. And lately, Oracle—long known for its own brand of xenophobia and disdain for direct competitors—has been making a lot of waves by forging new alliances with old foes. This is opening up potentially lucrative new frontiers for business partners at all levels.

Database management systems support numerous unique date and time functions - and while the date-related functions are many, they do not go far enough. One date-driven circumstance often encountered has to do with objects having a type of date range that needs to be associated with it. While there are some exceptions, this date range need generally ends up implemented via two distinct date columns—one signaling the "start" and the other designating the "end." Maybe, should the creative juices of DBMS builders' flow, such things as numeric-range-datatypes could be created in addition to a date-range data-type. Who knows where things could end up?

Many of the new features coming in SQL Server 2014, now available in Community Technology Preview, are encapsulated within broader and rather intuitive categories. The major categories for new features in SQL Server 2014 are Mission-Critical Performance Enhancements, Business Intelligence Insights, and Hybrid Cloud Enhancements. In addition, one of the interesting knock-on effects of retooling SQL Server to run in the cloud is that the code has tightened up a lot.

DBAs need to make many different types of changes to a database over its lifetime. Some will be simple and easy to implement, others much more difficult and complex. It is the DBA's job to understand the best way to implement any type of database change, but often, simple changes become more difficult in the real world. Database change management tools help to make this job easier and is one of the first tools acquired by many organizations when they implement a database of any size.

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.

Just about every company with a DBMS has that binder full of corporate and/or IT standards. That one over there in the corner with the cobwebs on it — the one that you only use when you need an excuse to avoid work. Okay, well, maybe it's not quite that bad. Your standards documents could be on the company intranet or some other online mechanism (but chances are there will be virtual cobwebs on your online standards manuals, too).

I was recently chatting with a good friend of mine who's very highly placed in the Microsoft SQL Server team. Our conversation was wide ranging and covered a lot of topics, such as internal features and upcoming announcements. (I'm under at least three different NDA's. So don't expect me to give up anything too juicy or gossipy.) For example, we spent quite a while discussing the ton of great new features and improvements just over the horizon with the recent release of SQL Server 2014 CTP1.

A former colleague is looking for a database server to embed into an important new factory automation application his company is building. The application will manage data from a large number of sensor readings emanating from each new piece of industrial equipment his company manufactures. These values, such as operating temperature, material thickness, cutting depth, etc., fit into the data category commonly called "SCADA" - supervisory control and data acquisition. Storing, managing and analyzing this SCADA data is a critical enhancement to this colleague's new application. His large customers may have multiple locations worldwide and must be able to view and analyze the readings, both current and historical, from each piece of machinery across their enterprise.

Consider a professional baseball game or any other popular professional sporting event. When a fan sits in the upper deck of Dodger Stadium in Los Angeles, or any other sporting arena on earth, the fan is happily distracted from the real world. Ultimately, professional sports constitutes a trillion dollar industry - an industry whose product is on the surface entertainment but when one barely pierces that thin veneer it quickly becomes clear that the more significant product produced is data. A fan sitting in the upper deck does not think of it as such but the data scientist recognizes the innate value of the varied manifestations of the different forms of data being continuously produced. Much of this data is being used now but it will require a true Unified Data Strategy to fully exploit the data as a whole.

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.

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.
