Craig Mullins: Articles Published in 2008
The Database
Report: 2Q2008. This installment of "The Database Report" covers DBMS industry new for the second quarter of 2008, spanning April thru June.
Consider Data Access Auditing to Classify Database Data. A detailed classification of which data is being used, how it is being used, and when it is being used is required to align data with appropriate regulations and storage types. This article suggests one method for creating such a classification scheme.
The Rise of
Dynamic SQL. This month in z/Data Perspectives we examine the factors contributing to the increasing popularity of dynamic SQL in DB2 applications and systems.
The Growing
Importance of Metadata. Without metadata data cannot be turned into information. But aside from this fact, governmental regulations require the classification of data, which is also impossible without metadata. On Recovery
Service Levels. Well-planned recovery procedures should be able to assure a complete recovery of enterprise-critical data within a pre-defined time window that provides for minimum disruption of the business. However, within complex environments, it is nearly impossible to perform recovery tests without disrupting the production system. With these issues in mind, this article examines the risk management of business availability, especially focusing on database health.
The Cost of
a Data Breach. If you read the It press these days you know that data breaches are quite pervasive. We keep hearing about data being lost, stolen, and nefariously accessed. It is all enough to give a data professional a throbbing headache. But what is the actual cost of these data breaches?
Use
Real Time Statistics to Automate Your Database Maintenance. This month in z/Data Perspectives we examine the Real Time Statistics (RTS) and the benefits that can be accrued by using RTS.
The Database
Report: 1Q2008. This installment of "The Database Report" covers DBMS industry new for the first quarter of 2008, spanning January thru March. Database Data Needs Long-Term
(100 Year) Archiving Solution. Long-term data retention is a reality. And in this edition of the DBA Corner column I review a recent survey on archiving and relate the findings to the retention and preservation of database for long durations. Collecting
Histogram Statistics With RUNSTATS. This article discusses one of the many new enhancements that have found their way into DB2 9 for z/OS -- the ability to gather histogram statistics with the IBM RUNSTATS utility.
An Update on Data Professional's Salaries. In this edition of the DBA Corner, I review the recent salary surveys with a particular emphasis on the pay for data-related jobs.
Much Ado About DB2 Locking. This month in z/Data Perspectives we examine the new locking-related features of DB2 for z/OS.
Keeping Up With The DBMS. One of the more troubling aspects of the DBA job these dayss is keeping up with the latest version of the DBMS. A typical release cycle for DBMS software is 18 to 24 months for major releases with constant bug fixes and maintenance delivered in between major releases. Indeed, keeping DBMS software up-to-date can become a full-time job. Compliance Needs Drive Data Access Auditing
Requirements. An increasing number of regulations are being passed that require effort to be exerted to better secure and protect the accuracy and privacy of enterprise data. This expanding need for data auditability is the focus of this issue's column. Data Management Made News in 2007. In this month's edition of DBA Corner I take a look back at the machinations within the database market over the past year.
The Database
Report: 4Q2007. This installment of "The Database Report" covers DBMS industry new for the Fourth quarter of 2007, spanning October thru December.

But it is critical that retention policies not stop there. The transactional data stored in database systems also must be readily accessible in the event of an e-discovery request.
Simplified Database Search. This month in the DBA Corner we ruminate on methods of enabling an easier-to-use search capability for production databases much like the ubiquitous search capability available on the web.
The
Buffer Pool:
