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.

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.

Have you noticed that dynamic SQL is more popular today than ever before? There are a number of factors contributing to the success of dynamic SQL. Commercial off-the-shelf applications, such as SAP, Siebel, and PeopleSoft, utilize dynamic SQL exclusively. In many cases, too, dynamic SQL is the default choice for in-house application development.

In formulating the tenets of relational theory, issues anent to order were explicitly addressed. These relational theory tenets included defining a relational database so that it need have no concern with the order of columns in a row, or with the order of rows in a table. And yet, such a stance seems counter-intuitive since the database brings structure and organization to content. Chaos is the primordial soup from which all things originated. Thus it seems only reasonable that a relational database, being the best and brightest of its kind, should abhor such chaos and bring ever more order instead, right?

The time is past when the unique attributes of the MultiValue database model alone provided sufficient justification for the use of the technology, according to Pete Loveless.

With Quest's new tool, VSTS can now support both Oracle and SQL Server databases.

The optimizer is the heart and soul of a relational DBMS. It analyzes SQL statements and determines the most efficient access plan for satisfying each statement. The optimizer accomplishes this by parsing the SQL statement to determine which tables and columns must be accessed. It then queries system information and statistics stored in the system catalog and directory to determine the best method of accomplishing the tasks necessary to satisfy the request.

Occasionally the database under design becomes more than a one-off project. For example, the data mart or data warehouse might act as a profit center for the organization, and as a solution sold to many customers. The possibility exists to capture a basic truth for a given industry in a simple universal design exactly suiting everyone. But unless the situation really qualifies as a valid "one-size-fits-all" circumstance, one needs a level of customization within the architecture.

SQL Server has supported VLDBs (very large databases) for some time now. Back in the SQL Server 2000 days, I recall hearing multi-terabyte databases were unusual but doable. Now, they are commonplace, while databases in the hundreds of terabytes inhabit the part of the map that says "there be dragons." While VLDBs are quite common on SQL Server today, highly scalable systems that can be flexibly extended in the same fashion as Oracle/RAC are less so. So, how do you design a highly available architecture for SQL Server if it's not like Oracle/RAC.
