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.

DBAs and IT operational teams, pressured by the unabated flow of data streaming in from an ever wider range of sources, require proactive self-managing and automated systems to supplement or replace manual techniques and processes which are no longer scalable given the rate of data growth, according to the results of a new Independent Oracle Users Group (IOUG) study on database manageability. With input from 445 member respondents from within the IOUG community, the survey finds that forward-looking companies, led by Oracle technologists and DBAs, are meeting their growing data management challenges by employing more advanced database management policies. This survey was conducted by Unisphere Research, a division of Information Today, Inc., in partnership with Oracle Corporation. Among the key findings are that more than one-third of respondents indicate their companies' data stores are increasing at a rate greater than 20% a year, and, the survey finds, this growth is a main contributor to many of the difficulties DBAs currently face.

Furthering its support for Java-based mobile development, Oracle has announced Oracle Application Development Framework (ADF) Mobile Client, an extension of the Oracle Application Development Framework. A component of Oracle Fusion Middleware, Oracle ADF Mobile Client allows developers to extend their existing skills into mobile devices. It simplifies application creation and deployment using a single, standard Java user interface (UI) framework and tooling for all supported devices. Developers can build once and deploy to multiple devices - and as support for new devices is added in Oracle ADF Mobile Client, applications can be deployed to the new platforms without redevelopment. "It is all about linking the enterprise and mobile devices," Duncan Mills, senior director of product management for Oracle Fusion, tells 5 Minute Briefing. The approach takes Oracle's existing philosophy of "a single set of development skills, broadening the envelope to include native mobile applications which can run online and offline, and then managing all of the tricky data synchronization tasks on top of that."

Microsoft extended support for all editions of SQL Server 7.0 ended on Jan. 11. Considering that this edition was initially replaced 11 years ago by SQL Server 2000 (and there have been three more major releases since), this may not seem to be big news. However, I'm always amazed by the number of DBAs I meet who are still responsible for keeping a few instances of this, or even version 6.5, running in production.

2010 was a very good year for open source databases, with the top RDBMSs like Oracle's MySQL and PostgreSQL showing momentum with impressive customer gains and new releases that delivered much-desired functionality. Everything points to similar energy in 2011 with the top analyst groups and big-name system integrators like Accenture proclaiming "the coming age of open source." A study done by Accenture in late 2010 showed that more than two-thirds of organizations anticipate increased investment in open source, with more than one-third expecting to migrate mission-critical software to open source in the next 12 months.

One of the ongoing goals of database administration is to minimize downtime and improve availability. If the DBMS is down, data cannot be accessed. If the data is not available, applications cannot run. And if your applications cannot run, your company is losing business. Lost business translates into lower earnings and perhaps even a lower stock valuation for your company. These are all detrimental to the business and therefore, the DBA is called upon to do everything in his or her power to ensure that databases are kept online and operational.

A new survey of database administrators and managers reveals that a pervasive culture of complacency hampers information security efforts, and as a result of lax practices and oversight, sensitive data is being left vulnerable to tampering and theft. While tools and technologies provide multiple layers of data security both inside and outside the firewall, organizations appear to lack the awareness and will to make security stick. The study, "Data in the Dark: Organizational Disconnect Hampers Information Security," was conducted by Unisphere Research among 761 members of PASS, the Professional Association for SQL Server, in September 2010. The survey was fielded in partnership with Application Security, Inc.

To help organizations prevent internal and external attacks from reaching their enterprise database targets, Oracle has introduced Oracle Database Firewall, which is intended to act as the "first line of defense for databases."

A new survey of 430 members of the Oracle Applications Users Group (OAUG) reveals that organizations lack a sense of urgency about securing critical data, and the greatest challenges to securing application and data environments are primarily organizational and budget-related. The survey was conducted by Unisphere Research, a division of Information Today, Inc., in partnership with Application Security, Inc. (AppSec), a provider of database security, risk and compliance solutions, in December 2010. According to the OAUG's 2011 Data Security report, "Managing Information in Insecure Times," 53% of respondents stated that budget was the greatest impediment holding back information security efforts. Thirty-three percent claimed a lack of an understanding of the threats prevents them from rallying support for countermeasures. And more than one-quarter of respondents cited a disconnect between IT teams and executive management as a major impediment to implementing proper security measures. The study shows a serious lack of understanding and concern for data and application security in today's organizations, according to Thom VanHorn, vice president global marketing at AppSec. "My take-away from the study is that there is a lack of communication, there is a lack of buy-in at the highest levels, and there is not a focus on implementing best practices," VanHorn says.

Depending on their industry sectors, many database professionals have to deal with audits at some stage, often removing vital years off their lives and inches off their hairlines! Having worked as a DBA in the financial industry, I've experienced both internal and external auditor visits on multiple occasions. In all cases, we pretty much had to drop all other work to ensure they were provided with the relevant information, or to implement the changes they required so we could provide the information in the future. The auditors' levels of experience and understanding varied wildly. This was not their fault, as they are not paid to be database experts, but it could make them frustrating to work with.

One of the most fertile grounds for disagreement between database professionals is the appropriate usage of views. Some analysts promote the liberal creation and usage of views, whereas others preach a more conservative approach. When properly implemented and managed, views can be fantastic tools that help to ease data access and simplify development. Although views are simple to create and implement, few organizations take a systematic and logical approach to view creation. And therein lies the controversy. A strategic and reasonable policy guiding the creation and maintenance of views is required to avoid a muddled and confused mish-mash of view usage. Basically, views are very useful when implemented wisely, but can be an administrative burden if implemented without planning.
