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.

Mid-sized businesses are using and saving more data than ever before. Indeed, the phenomenon that IT engineers have come to refer to as "big data" is being felt in businesses of all sizes. At the same time, however, organizations are facing reduced budgets. Regardless of how much data their likely overburdened IT staff must manage today and tomorrow, mid-sized businesses must find ways to save money by keeping a tight rein on both capital and operational expenditures.

Oracle has introduced Oracle Business Intelligence 11g. "The new release allows customers to integrate relational and OLAP analysis across a multitude of different federated data sources and presents that in a very simple way to end users so that they can do analysis on their own without understanding or needing to know that there might be potentially multiple data sources beneath," Paul Rodwick, vice president of product management for Oracle Business Intelligence, tells DBTA. Representing the result of a large investment in simplifying the end user experience, adds Rodwick, companies will see "very interactive dashboards that are completely live and completely interconnected and allow business people to do their own analysis without really needing to go into any kind of query tool." The new release also provides new capablities for search and collaboration, and enhanced performance, scalability, and security through deeper integration with Oracle Enterprise Manager 11g and other components of Oracle Fusion Middleware.

UniVerse 11.1, scheduled for release in Q3 of this year, will include the External Database Access functionality that already exists in UniData. EDA allows users to map files to the format for another database, and then write directly to it. UniData EDA originally shipped with just a driver for DB2. "We released the API for building additional drivers with UniData 7.2. Once we were acquired by Rocket, we committed to delivering a driver for Microsoft SQL Server. Now we're in the process of building a driver that will work with Oracle," Susie Siegesmund, vice president and general manager, Rocket U2, tells 5 Minute Briefing. Rocket U2 is now looking for people who want to help by testing the driver with their application.

ONware is now offering the ability to use PostgreSQL as a database system for applications developed for U2, D3, MVON and other MultiValue and PICK database environments. The new support for PostgreSQL has been added based on feedback from prospective customers in the MultiValue world, Jack Roth, director of operations, ONgroup, tells 5 Minute Briefing. Roth notes that he has come across a number of companies that have other development in their organizations in Postgres. "They like Postgres and if they can support one database as opposed to two very dissimilar databases, that is an advantage for them," he explains.

Compliance is one of the most interesting elements of any data management plan - it's a microcosm of evolution in action. When many of the laws that impacted data retention were first enacted, business wasn't collecting a lot of information. Now, data collection happens everywhere. And, as citizens have come to realize that more and more of the information about their daily lives is recorded, they demand their governments provide privacy and protection from misuse of that data.

In this issue's column I'll be providing a fundamental introduction to database and database management concepts. Many of you may think that they understand the basic concepts and fundamentals of database technology. But quite a few of you likely do not, so please do not skip over this. First of all, what is a database? DB2 is not a database; neither are Informix, Oracle and SQL Server. Each of these is a DBMS, or Database Management System. You can use DB2 (or Informix or SQL Server) to create a database, but DB2, in and of itself, is not a database.

When integrating data, evaluating objects from multiple sources aids in determining their equivalence. Each source may identify customers, but determining which customer from each system represents the same customer can prove daunting. Sometimes matching things is straight-forward; for example, if all sources should have an accurate social security number or taxpayer ID, success involves simply linking the matching numbers.

Everybody seems to agree with the need for organizations to do a better job of protecting personal information. Every week the media brings us reports of more data breaches, and no organization is immune. Hospitals, universities, insurers, retailers, and state and federal agencies all have been the victims of breach events, often at significant costs. State privacy laws such as the new Massachusetts privacy statutes have placed the burden of protecting sensitive information squarely on the shoulders of the organizations that collect and use it. While some managers might view this as yet one more compliance hurdle to worry about, we feel it presents an excellent opportunity to evaluate existing practices and procedures. The good news is that there are some great solutions available today that can help organizations of all stripes address these requirements while at the same time tightening data security practices, streamlining operations, and improving governance.

If managing your corporate data for the long term isn't currently on your mind, it should be, and in several different ways: cost, performance, business continuity, and compliance. First, let's talk about cost and performance. You want to manage your database infrastructure so it can support your growing data needs within budget, while providing acceptable performance to your users. SANs (storage area networks) have enabled us to meet these contradicting goals over the last decade, and, as I mentioned in a previous column, SAN vendors are offering innovative new technologies to push on-disk storage even further. Some interesting new strategies also are helping organizations achieve a more balanced mix of cost versus performance through the use of "tiered storage."

Quality can be a hard thing to define. What is good and what is bad may not be easily identified and quantified. When a data mart accurately reflects data exactly as found in the source, should that be considered a quality result? If the source data is bad, is the data mart of high quality or not? If the data mart differs from the source, when is the difference an improvement of quality and when is said difference evidence of diminished quality? While it may seem self-evident that correcting the source of load data would be the "right" thing to do, in practice that direction is not necessarily self-evident. The reasons supporting this nonintuitive approach are varied. Sometimes changes to the source impact other processes that must not change, or the changes will expose problems that may provoke undesired political fallout, or it may simply be that making the proper adjustments to the source application would prove too costly to the organization. For all these reasons and more, in the world of business intelligence, the dependent data often is expected to be of higher quality than the source data. In order for that improvement to occur, data placed within the dependent mart or data warehouse must be altered from the source. Sometimes these alterations become codified within the process migrating data from the source. Other times changes are made via one-time ad hoc updates. Either way, this alteration leads to a situation in which the dependent data will no longer equate one-for-one to the source data. Superficial comparisons of this altered content will highlight the disparity that what exists for analytics is not the same as what exists for the operational system.

Before we go any further, let me briefly answer the question posed in this column's title: "No Way!" OK ... with that out of the way, let's discuss the issue ... Every so often, some industry pundit gets his opinions published by declaring that "Database administrators are obsolete" or that "we no longer need DBAs." Every time I hear this, it makes me shake my head sadly as I regard just how gullible IT publications can be.
