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.

Just about every company with a DBMS has that binder full of corporate and/or IT standards. That one over there in the corner with the cobwebs on it — the one that you only use when you need an excuse to avoid work. Okay, well, maybe it's not quite that bad. Your standards documents could be on the company intranet or some other online mechanism (but chances are there will be virtual cobwebs on your online standards manuals, too).

I was recently chatting with a good friend of mine who's very highly placed in the Microsoft SQL Server team. Our conversation was wide ranging and covered a lot of topics, such as internal features and upcoming announcements. (I'm under at least three different NDA's. So don't expect me to give up anything too juicy or gossipy.) For example, we spent quite a while discussing the ton of great new features and improvements just over the horizon with the recent release of SQL Server 2014 CTP1.

A former colleague is looking for a database server to embed into an important new factory automation application his company is building. The application will manage data from a large number of sensor readings emanating from each new piece of industrial equipment his company manufactures. These values, such as operating temperature, material thickness, cutting depth, etc., fit into the data category commonly called "SCADA" - supervisory control and data acquisition. Storing, managing and analyzing this SCADA data is a critical enhancement to this colleague's new application. His large customers may have multiple locations worldwide and must be able to view and analyze the readings, both current and historical, from each piece of machinery across their enterprise.

One of the principles within relational theory is that each entity's row or tuple be uniquely identifiable. This means the defined structure includes some combination of attributes whose populated values serve to identify an individual row within the table/relation. This, or these, attribute(s) are the candidate key(s) for the structure. The candidate key is also known as the primary key, or if a structure has multiple candidate keys, then one of them is designated as the primary key. When building up a logical design, primary keys should be identified by the actual data points in play.

These are heady times for data products vendors and their enterprise customers. When business leaders talk about success these days, they often are alluding to a new-found appreciation for their data environments. It can even be said that the tech vendors that are making the biggest difference in today's business world are no longer software companies at all; rather, they are "data" companies, with all that implies. Enterprises are reaching out to vendors for help in navigating through the fast-moving, and often unforgiving, digital realm. The data vendors that are leading their respective markets are those that know how to provide the tools, techniques, and hand-holding needed to manage and sift through gigabytes', terabytes', and petabytes' worth of data to extract tiny but valuable nuggets of information to guide business leaders as to what they should do next.

The grain of a fact table is derived by the dimensions with which the fact is associated. For example, should a fact have associations with a Day dimension, a Location dimension, a Customer dimension, and a Product dimension, then the usual assumption would be for the fact to be described as being at a "by Day," "by Location," "by Customer," "by Product" metrics level. Evidence of this specific level of granularity for the fact table is seen by the primary key of the fact being the composite of the Day dimension key, Location dimension key, Customer dimension key, and Product dimension key. However, this granularity and these relationships are easily disrupted.

Although storage management can be an afterthought for the DBA, it really shouldn't be. Storage issues are vitally important and unless managed appropriately, it can be very costly. The cost of managing storage can be as much as 10 times higher than the initial cost of acquiring the storage—and the growth rate for disk storage was 37% between 1996 and 2007. Even so, it is common for storage-related issues to be relegated to the backburner by DBAs, but every database professional should understand modern storage basics.
