Hi Folks, I recently published a new technical paper on the use of auxiliary processors on IBM System z class machines to support virtualization of mainframe data that allows you to bypass the need for extracting data prior to using that data for reporting and analysis. You can access the paper, which was sponsored by Rocket Software, via this link. Please email me or post comments and let me know what you think!
A few years ago I was working on configuring a test for comparing data transformation and loading into a variety of target platforms. Essentially I was hoping to assess the comparative performance of different data management schemes (open source relational databases, enterprise versions of relational databases, columnar data stores, and other NoSQL-style schemes). But to do this, I had two constraints that I needed to overcome. The first was the need for a data set that was massive enough to really push the envelope when it came to evaluating different aspects of performance. The second was a little subtler: I needed the data set to exhibit certain data error and inconsistency characteristics that simulated a real-life scenario.

Even if in reality the dividing lines for data management are not always well-defined, it is possible to organize different aspects of information management within a virtual stack that suggests the interfaces and dependencies across different functional layers, which we will examine from the bottom – up.

Data governance is a practice for ensuring that policies about information acquisition, use, protection, and disposition are defined, approved, and importantly, observed across the organization. Information policies are defined in relation to business policies and must be aligned with the corporate mission. Read more
I am assembling some presentations for a client on information strategy and thought it it might be interesting to share some of those thoughts as I develop my materials. This post provides a framing definition of information strategy.
A strategy is a plan and set of policies intended to help achieve specific objectives. An information strategy elucidates the way that principles for information use across the organization will help the organization achieve its intended goals. Read more
