Part I: Getting Started with your Web Browser
Open your web browser, Internet Explorer on Windows.
(Note: You can also choose to use FireFox on a Macintosh.)
If you are working with Windows XP, and plan to export data in either XLS or CSV
format (readable by Excel), make a change in Internet Explorer’s options for adding
Trusted Sites. Directions are in Appendix A. (Windows 2000 does not require any
change in options.) Depending on your computer’s settings, Excel may open in a
separate window. If instead, it opens inside Internet Explorer, as a plug-in, and you
would prefer a separate window, follow the directions in Appendix B.
Type dataview.wnyric.org into the location bar of your browser (do not enter www in
front of the address).
The dataview home page should look like the image shown below.
On the left side of the page, there are some web page links to additional information.
Clicking on Home (after you have clicked on any of the other links) will bring you back
to this page, for Log On options. Clicking on Liaison & Trainers will show you each of
the local BOCES designated Data Warehouse support personnel. Clicking on Districts
will allow you to see what other districts are participating in the Data Warehouse Service,
along with a contact name at each district. To access Cognos’ own user manuals, you can
click on Cognos Help. These manuals show all the functionality of the web applications,
but the examples are based on business use (product sales, salesmen, etc.). Clicking on
Data Readiness is one of the forms for communicating with our users and will be
covered in more detail in the last section of this guide - Communicating and Getting
Assistance.

Part II: Navigating and Customizing the COGNOS Connection Web Portal
You should now be looking at a screen like the one below. This is the Public Folders
screen, and is the default home page. You may decide to change your home page after
you see what’s available, in Public Folders and My Folders.
The COGNOS Connection portal provides users with a single web-based point of access
to data cubes and reports (each cube is a specific subset of the whole data warehouse).
In the Public Folders, you will see all of the accessible folders, available to all districts
that are members of the Data Warehouse Service. (These are the same groups of cubes as
you are used to from the previous version of COGNOS.) As you work with the various
cubes, you may want to save your own custom views in the area called My Folders.
What you save here will only be seen by using your ID and password.
There are many items in the toolbar to help you in find and organize cubes and reports.
Use the Search feature by typing a word in the box and click here to see the results list.
Click on one to go directly there.

You can change the view to show details, explaining what is in the items.
Click here to see the Detail View.
Click here if you prefer the List View.
Now click on My Folders. This
will be empty until you create
your own folders, save cube
views, or save finished reports.
You can just place your saved views and reports directly in My Folders, or you may
prefer to organize it with multiple folders, as you would with files on your hard drive.
To create a New Folder, click here. Specify a folder name (description etc. is optional)
and click OK.
The next button starts the New Job wizard, allowing you to set up a report to run on a
certain date, or on recurring dates, in the desired format(s).
Although most people will keep internet bookmarks/favorites in their browser directly,
you can use this button to add a New URL to one of your folders.
You may prefer to create a New Page (another tab next to My Folders) instead of, or in
addition to, having more folders inside My Folders.

Part III: Manipulating Cubes with PowerPlay Web Explorer
PowerPlay allows the user to disaggregate and analyze the student (or budgetary) data.
The following section covers features of PowerPlay, using the NYS Assessments cube
and Student Demographic cube, to look at student data for my imaginary “Central School
District” and their buildings, “Main Street ES”, “School Road MS”, “Center HS” and
“Out of District Service Provider”.
From the Public Folders screen, click on the Student Summary Cubes folder, and then
click on the NYS Assessments (K-12) cube. (Each function of the software will work in
any cube selection.)
If your district has more buildings,
there will see more columns displayed.
dimension
viewer
tool bar
dimension
line
data display area
The dimension line lists the data fields used in this cube. To move to the right or left in
the list, use the arrows at the beginning and end of the line.
To see all of the dimensions at the same time, in a wrapped list, click here.
Now that the full dimension line is visible, close the dimension viewer area by
clicking here. That allows for more space on the screen for the data.
Erie 1 BOCES, 2007
Page 10
Western New York Regional Information Center
Data Warehouse User Guide
Now the dimension line looks like this, wrapping the dimension items in this cube.
The data display area shows the selected data elements. This display style is called the
crosstab display and is the default style. Other styles include the indented crosstab and
the various graphs. The tool bar at the bottom of the screen contains several buttons or
icons for manipulating your view of the data, as well as exporting and saving the data.
Their use will be covered later.
When viewing any cube…
The first dimension on the dimension line is the default for your row headings.
The second dimension is the default for the column headings.
The data inside each cell of the display represents (in this cube) the number of assessment
records that correspond to each assessment type, for each year. We need more detail to
analyze the data.
To access the next level of detail (subsets of data), you will be drilling down (also called
filtering). There are a few ways to accomplish this task.
The first way to drill down is from the data display. Move your mouse cursor over the
row heading NYS and click on it. This drills down one level, to show all of the different
NYS assessments in the multiple years of data in this cube.
Click on the row heading ELA to drill down another layer, to see each of the ELA 3-8.
Erie 1 BOCES, 2007
Page 11
Western New York Regional Information Center
Data Warehouse User Guide
For everything you learn, you need be able to undo it. To go back to All Assessments,
click on ELA on the dimension line to see the selections.
.
Then click on All Assessments
here. This called drilling up.
To drill down multiple levels at once, click on the All Assessments dimension to open it,
float your mouse over a subject, and then click on the desired assessment. In this
example, float over ELA and then click on Grade 3 Math.
The resulting display shows the number of assessments records for each year, with a
district total at the right of the display.
The columns with zeros are wasting space on the screen. To clean up the display, click
on the zero suppression icon on the toolbar. (Click it again if you want to turn it off.)
If you click on the little arrow next to the icon, you will have the option of choosing from
full zero suppression, rows only, or columns only. This gives you more control.
Erie 1 BOCES, 2007
Page 12
Western New York Regional Information Center
Data Warehouse User Guide
Now the data display looks like this.
The process of setting constraints on any one or more dimensions is called filtering.
Place your mouse over
the dimension labeled
All Income Levels, and
click once to open the
selection menu. Slide
your mouse to your
choice, and click to
make the selection.
Place another filter on the dimension All Education Types, selecting Special Education.
Now the data display looks like this.
Notice that the dimension line reminds you what you have drilled down or filtered on, by
keeping those dimension labels in bold text.
To remove a filter, click on it on the dimension line, to open it, and then click on All… to
set it back up to the top of the hierarchy.
If you want to get back to the top of the hierarchy for all of the dimensions at once, there
is a shortcut. (You don’t have to open each dimension separately to select the top level.)
To the right of the dimension line, you will see a curved arrow,
pointing upward. Click on this button to reset all of the dimensions
at once. (The other arrow, to its right, is the wrap/unwrap tool.)
Erie 1 BOCES, 2007
Page 13
Western New York Regional Information Center
Data Warehouse User Guide
Let’s see what you have learned so far. Still in the NYA Assessments cube, drill down to
the NYS Math 3-8 assessments, filter on Special Education, and make sure you have the
zero suppression turned on. So far, we have looked at numbers of students in the data
display. You are probably more interested in seeing performance at levels 1, 2, 3 and 4.
What you really want to do is compare the data for each of those levels all on one screen.
The action by which you can compare sub-categories of a dimension on one screen is
called nesting. To accomplish this, drag and drop the desired dimension into position, in
this case, just to the right of the row headings.
Click and hold the mouse
button down over the
dimension All Standards Met,
then drag your cursor, until you
see the blue highlighted area,
and then let go.
The result looks like this, where each assessment now breaks out by performance levels.
Notice that for Grade 6 Math, there is
no row for Level 4. This is because
zero suppression is turned on, and
because there are no Special Ed.
Students performing at that level in
any year.
Erie 1 BOCES, 2007

Data Warehouse User Guide
You can also choose to nest in the columns instead of in the rows. Click and hold the
mouse button down over the dimension All Genders, and then drag, until you see the blue
highlighted area under the column headings, and then let go.
Here is the resulting display.
So you know how to create nested data, but you also need to know how to delete them.
To delete (remove a nest) in
the columns, click on the
narrow band to the left of the
nested column headings, and
then click on the delete icon.
Or…
If you prefer words to icons,
right-click on the narrow band,
and then click on Delete.
Erie 1 BOCES, 2007
Page 15
Western New York Regional Information Center
Data Warehouse User Guide
Similarly, to remove a nest in the rows,
you can either click on the narrow band
just above the nested row headings and
then on the delete icon,
Or…
Right-click on the band, and then click
on Delete.
Another way to use the drag and drop feature is for replacing columns or rows with
another dimension. Let’s say you want to look at the demographics of the students who
took the Math 4 assessment. In the NYS Assessments cube, drill down to NYS and then
Grade 4 Math, click on zero suppression, and then nest All Standards Met in the rows.
To replace the current column headings with the ethnicity sub-categories, click and drag
the All Ethnicity dimension until you have highlighted all the current column headings…
Erie 1 BOCES, 2007
Page 16
Western New York Regional Information Center
Data Warehouse User Guide
When you let go, the columns are replaced. (This is data for several years. If you want
to see just one year, place a filter. To compare Ethnicity by levels over time, nest the
years in the columns or the rows.)
Is the data display too wide? Or, maybe you just prefer the levels as your columns, and
the Ethnicity headings in the rows.
You can click on the Swap button on the tool bar to get this view.
Another example of
changing the shape of
the data display is used
when you have multiple
nests in the rows. Here,
I have nested Education
Types and then nested
Genders into the rows.
Notice how the series of
row headings take up a
lot of space left to right.
Erie 1 BOCES, 2007

The solution to this problem is the Indented Crosstab
display, available from the toolbar at the bottom of
your screen. The default display style is called a
Crosstab, and shows here.
To access the Indented Crosstab, click on the arrow to
the right to bring up the selections, and click on it.
Your display will look similar to the one below. The row headings take up much less
screen space. There is more room for the data itself on the screen. If you don’t prefer
this display style, click on the icon again to open it, and select Crosstab to set it back.
So far, the numbers appearing in the cells of a crosstab display represent the count of
students who fall into a particular category. Here is an earlier example.

Interpreting the performance can be difficult, for example, when comparing multiple
years of Grade 4 Math that show classes of different sizes for each year. For a better
comparison, the relative or proportional performance is what should be analyzed. We
want the percent at each level, for each year.
There are two ways to change the display from the count of student assessments to a
percentage option. You can right-click on as values in the display, to bring up the menu
of possible choices.
Then click on the as % of…
that will place the 100%
totals where it best suits the
analysis of the data. For this
example, I want to select
as % of column total.
If you don’t like right-clicking, you can also access the percentage selections by clicking
on the Specify display options icon on the tool bar, which opens a list of items.
Click on the first item, Options.
You will get the dialog box shown
here.
Then click on
the arrow to
open the menu.
Click on your
selection, and
then click on
OK.

Using % of column total, the comparison of change over time is now easily viewed.
When analyzing nested data, selecting as % of column subtotal (or row subtotal) may
be best.
Choosing % of grand total creates a display where the % in each cell is that part of the
whole district.

Let’s take a look at some Regents data, in the process of showing more of the PowerPlay
features. Starting from Public Folders, click on the Student Summary Cubes folder
and then the NYS Assessments cube. Remember to wrap the dimension line to show all
of the fields of data. Below, I have already filtered on Regents (from All Assessments),
clicked on zero suppression, and replaced my columns with All Standards Met.
When viewing any cube, you may want to limit the rows viewed at one time. If there
were rows of zeros to eliminate, you could use Zero Suppression. In this case, all of the
rows have data. But if you are the Math/Science department head at this school district,
you just want to analyze the rows for the Math and Science exams.
The solution is to use the Hide/Show feature.
Right-click on the white space in one of the row
(or column) headings that you want to hide.
From the fly-out menu, click on Hide Selection
to hide just this one row. To hide multiple rows,
selecting from a dialog box, click on Hide/Show.
Since I already hid Second Languages, it shows under the
Hidden Categories on the right. Click any category on the
left, and click the move button to place it on the right.
When you have moved the desired categories, click OK to
complete the process. (To Show a category, move it from
right to left.)
Erie 1 BOCES, 2007

Here is the result of hiding all but two rows of data. Notice that the column totals still
show, and that the summations still include the hidden rows! To hide the totals, you can
right-click on the heading Regents, and then click on Hide Selection.
Now the display shows just what I want to see.
You can also access Hide/Show from the tool bar. But before you click on the icon, you
must highlight one row (or column). To highlight, click near a heading (clicking on a
heading will drill down).
Let’s go a step further. The Curriculum Coordinator wants to know the number of
students that were below the standard in Math and Science respectively. (You decide
whether 55%-64% is above or below passing in your school.)
Let the software do the Math. Right-click
near the Scored below 55% heading and then
left-click on Insert Calculation. Or, you can
click near the heading to highlight it, and then
click on the icon on the tool bar instead.
Either way, you will see a dialog box to set up the calculation.
Erie 1 BOCES, 2007
Page 22

Select the operation, type in a calculation name (this will be your new column heading),
highlight the categories to be included (hold down the control key while clicking), and
then click on OK. The result is below. Notice how the new column appears in italics.
Now here is a test of your knowledge so far. Create another calculation for the students
above the standard (add columns 65%-84% and 85%-100%). Use the Hide/Show feature
to show all subject areas (drill up to Regents subjects). Use Hide/Show to display only
your calculated columns, below standard and above standard. Finally, compare the
percentage of students who were above and below standard (using % of row total).
Your screen should look something like this.
You can choose to see this in graph form. There are several graphs to choose from on
the tool bar. Click on the arrow here to see all of the choices.
Depending on the data you choose to display in a
graph, one may do a better job than another in
representing the data in a usable way. In this
example, the clustered bar graph is a good choice.
Keep in mind that the bars or sections of a graph,
break down by the column headings that were in
the crosstab display.

Here are the rows from the
original crosstab display.
The columns are
represented here.
If you aren’t happy with how the categories are displayed, try clicking on the Swap
button (swapping rows for columns affects the graphs as well as the crosstab).
Which way do
you prefer?
There is no
right or wrong
choice. It’s a
matter of what
way you want
to analyze the
data.
Some people like numeric displays, some prefer graphs, but you may want to show both
at once. Click on the specify display options icon, and then click on Split View choice.

feature, first click on the specify display options icon, and then click on Options.
Or, you can right-click anywhere on your graph, and then left-click on display options.
(This is the same dialog box used before to change to a percentage display.) On the right,

Set this to find text in Cube. When you click on Find, the results will appear on the right.
You can then choose to use that field to create a

For this example, you are looking for the 04-05 population data disaggregated by gender,
and by regular and special education, for each grade level.
Do the following…
Filter on your Middle School and filter on the year 2004-05. Replace the columns with
Gender and replace the rows with Education Types. Nest Grades in the columns and

For the next ranking example, first
drill down to the 2003-04 year, and
then hide the January data column as
well as the column totals on the right.
It should look like this.
Use Insert Rank, and make the selections as shown
here… notice this time, the sorting order is set to
Ascending. Click on OK.
See how the rows are
now sorted by their
rank, instead of the
original order by the
key idea headings.

This next feature was designed more for a business application of data analysis, rather
than an educational setting. (Please share any useful applications you discover.)
Using the 80/20 Suppression, removes rows or columns whose values do not contribute
to the top 80% of results. It then summarizes the removed data into a category called
"Other." Click it once to turn it on and again to turn it off.
Custom Exception Highlighting allows you to define and apply color formatting to
defined numerical ranges appearing in selected rows or columns.
Starting again from Public Folders, go to the Student Summary Cubes folder and then
go to the NYS Assessments cube. Drill down to Science (from All Assessments to
Regents to Science). Use zero suppression and nest All Standards Met in the rows.

Let’s say that I only want to see the most recent 3 years of data. How can this be done?
One could use the Hide/Show feature to hide the rows not wanted. But then the totals on
the right, for All Test Dates are still based on all the years, so they don’t make any sense.
I could choose to hide the summary column, and then use the calculation feature to create
my own totals… but wait, the next item on the toolbar, called Custom Subsets, is easier.
Hold down the Ctrl key on your
keyboard, and click near the
column headings, to highlight the
ones you want to keep visible.
Right-click near one of those row
headings to get the fly-out menu,
and left-click on Create Custom
Subset. Or, to avoid rightclicking, you can just click on the
Custom Subsets icon on the
toolbar, and bring up a dialog box.
Note:
If you use this from the fly-out
menu, the default name of the new
subset will be ‘Custom Subset 1’.
If you want to decide the name of
the subset, use the toolbar icon to
get to the dialog box.
Type the name here.
Select the dimension from which
you will select for the subset list.
Then click on Next.

Highlight each item and then click on the green arrow to bring them to the right side.
Move them in the order in which you want them to appear in the cube view.
When all the items are in the results set, click on Finish.
Now, the named subset shows up in the dimension line and the label for the totals here.
Also, notice that all the totals are calculated correctly.

Part IV: Drilling Through with ReportNet Web Reports
Below, I have disaggregated student data to the point where a crosstab displays numbers
of responses in the Item Response Math 8 cube, disaggregated by levels 1 through 4, for
the year 2004-05. You want to know who the students are, what their individual
responses were, especially for students at levels 1 an 2. The process called Drill Through
launches a predefined query, based on the selections you have made within PowerPlay,
resulting in a ReportNet Web Report in the Adobe PDF file format.
Viewing this type of
detailed report begins with
your manipulation of a
PowerPlay cube, until you
are looking at the desired
subset of data.
Then you can click on the
Drill Through button.
You will get a confirmation page (which helps our programmers if you have a problem).
Just click on OK to continue.

question, compared to your BOCES region of component school districts, and also
compared to all districts combined (including districts who scan answer sheets from O/N,
Erie 1, Erie 2, CA, GST, Monroe 1, Monroe 2, WFL, GV, Rochester, and Buffalo).
