IBM DB2 Web Query for i is an analytics tool for modernizing Query/400 reports and delivering analytics to the web or mobile devices. It's a web-based Business Intelligence (BI) solution for visualizing, analyzing, and sharing critical business data. Available since 2007 on the IBM i platform, DB2 Web Query has delivered through the years a steady heartbeat of new function.

 

One of the new functions recently delivered is Wizard Analytics. Wizard Analytics provides a jump start into reporting, allowing individuals to generate reports and dashboards against their DB2, spreadsheet, or delimited flat file data with a few clicks of the mouse! Wizard Analytics combines data upload, metadata definition, data profiling, and report generation into a single workflow. Business analysts, developers, administrators, and even non-technical individuals can get started generating sophisticated reports and visualizationsover their own datain minutes!

 

Wizard Analytics consists of two wizards:

  • The Upload Wizard, featured in this Part 1 article, guides users through the process of uploading data from a PC into DB2 for i.
  • The Metadata Wizard, featured in Part 2, connects to existing DB2 data sources (or another supported relational data adapter).

 

Both wizards automatically create a standard suite of reports, charts, and dashboards over the data.

 

Upload Wizard

The Upload Wizard uploads data from Excel spreadsheets or delimited flat files on your PC into DB2 for i. It provides a two-step process that

  • Uploads the data
  • Automatically creates metadata into application folders

 

And then, touch-free, builds a suite of reports, charts, and dashboards.

 

To launch the Upload Wizard from the Web Query BI portal, create a top-level folder (or choose an existing one). Right-click it, select Upload, and select Wizard, as shown in Figure 1.

A dialog pops up, and the first step, Upload Desktop File, is highlighted on the ribbon. You are prompted for the file you want to upload. Either drag the spreadsheet you want to upload onto this panel from Windows Explorer or click Select Upload File to navigate and select it. See Figure 2.

Figure 2: The first step of the two-step process is to select the file.

 

Next, tell Web Query how the data should be interpreted. As shown in Figure 3, you can indicate such things as the number of header rows, whether to create/append/replace the target DB2 table, or which sheet of a spreadsheet to use.

As step 1 completes, the data is uploaded to DB2 on i and metadata is created over it. Metadata describes the data and is an extremely important concept for true business intelligence tools as it simplifies the structures of the data for report authors and end users.


Next, step 2, Measures and Dimensions, is highlighted on the ribbon. The wizard makes assumptions about your data, categorizing it into measures, dimensions, and hierarchies, as shown in Figure 4. This step will be explained in more detail in Wizard Analytics, Part 2, but suffice to say that you have the opportunity to change the assumptions, including hierarchy ordering.

The Express Analytics Generator kicks in and builds an impressive set of reports. Figure 5 shows a sample dashboard consisting of three charts and an Active Report. The charts utilize the latest capabilities of the HTML5 Web standard, including animation and attractive gradient effects.

The wizard typically generates between 20 and 40 reports, placing them into subfolders of the top-level folder you started with. The actual number depends on how many measurements (typically numerical fields like REVENUE or COST_OF_GOODS_SOLD) are found in the data or identified by you. As you can see in Figure 6, the wizard generates a set of reports for each measure, a set of reports by transaction, and more.

Besides dashboards and charts, several other report types are generated:

  • A drill-down that hides data in a report until you click to reveal a new level of detail.
  • An Active Report that allows you to work with the data in the report, for example, to sort or filter fields.
  • An accordion, which expands or collapses fields to focus on certain elements, as in Figure 7.

The generated reports can be deployed in any number of ways: synch them with a mobile device, schedule them to run and send out to a distribution list, or place any individual report in an active or personal portal dashboard. You can also learn and build from them, using them as examples when developing other customized reports, to further exploit the relevance and usefulness of your data.

 

Some Additional Info

The Wizard Analytics feature is available in the recently released Web Query 2.1.1. It is also available in Web Query 2.1.0, with group PTF level 10 or later.

 

DB2 Web Query includes a Security Center to assign roles to authorized users of the product. In order to run the Upload Wizard, a user must be licensed to Web Query and defined in Security Center as one of the following:

  • A Web Query administrator
  • A Developer and DBA for the top-level folder
  • An Analyst and DBA for the top-level folder

 

Videos that demonstrate the wizard functions can be found along with a series of other "getting started" videos on the Web Query wiki here. And stay tuned for Wizard Analytics, Part 2 to learn more about the Metadata Wizard!
