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.

There comes a time at the start of a new engagement when the data architect must acquaint himself with the system for the first time. When first learning about a new application, the relevant data, and its foundational concepts, many questions are reviewed.

Before we even begin this month's column I had better define what I mean by a "black box." Simply put, a black box is a database access program that sits in-between your application programs and the DBMS. It is designed so that all application programs call the black box for data instead of writing SQL statements that are embedded into a program. The general idea behind such a contraption is that it will simplify application development because programmers will not need to know how to write SQL. Instead, programmers call the black box to request data. SQL statements become calls-and every programmer knows how to code a call, right?

While setting up a replication configuration, in which changes from a production or primary system are propagated to a standby or secondary system, is a fairly standard way to enable disaster recovery (DR) for business-critical databases, one of the important technology decisions that organizations must make upfront is the choice of the replication architecture, writes Ashish Ray, director of product management, high availability, at Oracle, in the current e-edition of Database Trends and Applications.

An inherent awkwardness exists in every many-to-many relationship between entities. Ambiguity causes this persistent awkwardness, primarily because a many-to-many relationship is such a fuzzy thing. In data discovery, encountering many-to-many relationships may actually expose a level of disregard about details by the subject matter experts.

The economy is a wreck and things will likely get worse before they improve. Unemployment is even worse; almost 600,000 jobs were lost in January 2009, sending the unemployment rate to 7.6%, the highest it has been in 16 years. So many data professionals are out there looking for their next challenge … and more probably will be job hunting before the year is out.

In a relational database approach, regardless of whether one is considering persisted data or transitory query results, almost everything is viewed as a logical table. Associations between these envisioned tables are based on data values, versus the alternative to the pre-relational idea of linking multiple data structures via "hidden" pointers maintained by the system. Relationships among objects are ultimately derived from the semantics of a situation.

The idea of "SQL Server in the cloud" is all the rage as I write this article. Many SQL Server experts already predict the demise of the IT data center and a complete upending of the current state of our industry, in which large enterprises can spend millions of dollars on SQL Server licenses, hardware and staff. I have to admit, when I first heard about this idea, I was ecstatic. What could be better for an enterprise than to have all the goodness of a SQL Server database with none of the hardware or staffing issues? However, on deeper examination, there is much about which to be cautious.
