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.



Database Management Articles

As my regular readers know, toward the end of each year I devote an edition of my column to review the significant data and database-related events of the past year. Of course, to meet my deadlines, the column is written before the year is over (this column is being written in November 2010), so please excuse any significant news that may have happened late in the year!

Red Gate has launched Data Compare for Oracle, a new tool that compares database table contents, highlights differences, generates SQL scripts to match the tables up, and automatically aligns them if desired. "More and more development teams are automating the building and testing of their Oracle databases," Tom Harris, head of Red Gate's Oracle tools division, tells 5 Minute Briefing. "Driven by an increased enthusiasm for agile development practices and scrum methodologies, many development team leads are borrowing techniques and technologies from application development. Tooling to generate database schemas and populate them with test data that can be run as part of the continuous integration process is key. The Deployment Suite for Oracle from Red Gate Software fills that gap."

At SAP TechEd 2010 held in Bangalore, India, last week, SAP AG announced availability of the new High-Performance Analytic Appliance (HANA). According to the company, the SAP in-memory computing engine that resides at the heart of SAP HANA is an integrated database and calculation layer that allows the processing of massive quantities of real-time data in main memory to provide immediate results from analyses and transactions. The engine supports industry standards such as SQL and MDX but also incorporates a high-performance calculation engine that embeds procedural language support directly into the database kernel. This approach, SAP explains, eliminates the need to read data from the database, process it, and then write data back to the database.

How does one know what one doesn't know? When evaluating what one knows, it is hard to know where to begin. The wise men say, "The more you know, the more you know you don't know." If one believes such commentary, what is known constitutes the tip of the proverbial iceberg. Databases have an easier time with such missing circumstances. If the rows of a database table are lacking referents, an outer join query filtering for NULLs might detail for you all the missing items. In developing and delivering projects, such a reference list for our minds to link to does not exist, for an outer join or anything else. Often, we do not know everything that needs to be done, particularly as a project starts. The difference between success and failure is not so much what one knows, but in how one handles the gaps between what is known now and what needs to be known before one finishes.

Fifty percent of enterprises are now using open source databases in a production environment, according to Forrester Research.This is a multi-digit jump from data available just a few years ago. And this isn't just one or two particular business verticals either; just about every sector of the economy is deploying open source databases in production now. Moreover, Forrester predicts that by 2014, 75% of all businesses will be using open source databases to power their key applications.

Assuring optimal performance of database applications starts with coding properly formulated SQL. Poorly written SQL and application code is the cause of most performance problems. As much as 75% of poor relational performance is caused by "bad" SQL and application code. But writing efficient SQL statements can be tricky. This is especially so for programmers new to a relational database environment or those who have never been trained to properly write SQL.

There comes a point in technology evolution when the question of adoption moves from "why implement" to "when to implement." Typically, we reach this inflection point when technology has developed sufficient functionality to represent a mature solution. In data virtualization, we have recently reached this inflection point of "When data virtualization?" Its functionality has matured to a fitness for both project-level and enterprise-scale implementations in a variety of use cases.

The year 2010 brought many new challenges and opportunities to data managers' jobs everywhere. Companies, still recovering from a savage recession, increasingly turned to the power of analytics to turn data stores into actionable insights, and hopefully gain an edge over less data-savvy competitors. At the same time, data managers and administrators alike found themselves tasked with managing and maintaining the integrity of rapidly multiplying volumes of data, often presented in a dizzying array of formats and structures. New tools and approaches were sought; and the market churning with promising new offerings embracing virtualization, consolidation and information lifecycle management. Where will this lead in the year ahead? Can we expect an acceleration of these initiatives and more? DBTA looked at new industry research, and spoke with leading experts in the data management space, to identify the top trends for 2011.

Psychiatrists report play is important for keeping our minds and bodies healthy and happy. It has been uncovered that without at least some play, we mentally and physically deteriorate. Lack of play can lead to depression. Our brains are so hardwired in their need for playful activities that without such expressions we loose focus. Play enhances the creativity and imagination within us. Likewise, play has a proper role within our work. And not just for the psychological benefit to the individual, but for the overall health of the organization. For an IT development group, play is essential for finding better ways to approach problems. Within an IT context, play involves evaluating new ways to handle old problems. Prototyping, at times, constitutes play. Prototypes can be used for more than just the practicalities of the user interface; sometimes a prototype of specific functions is necessary for comparisons in order to judge how non-obvious techniques may perform. Such prototype endeavors can involve not only new algorithms, but potentially variant data structures. Ideally, such prototypes will improve team understanding of the data structures and offer insights into potential new and innovative approaches.

I am attending my first Professional Association for SQL Server (PASS) Summit in Seattle this month. A lot of DBAs I meet are very keen to attend these events as the standard of speakers and quality of content is so high. Travel, accommodation and attendance costs are often prohibitive, however, let alone getting the time away from the office. Getting managers' approval to attend and justifying the cost can be difficult, especially for those of us based outside the U.S. PASS also runs a European event in April each year in Germany and, in the U.K., we have the SQL Bits conference. Those who wish to attend can still run into the same objections, however.
