CIS-355: Business Intelligence Applications

CIS-355 at Southern New Hampshire University introduces business intelligence (BI): the tools and practices that turn raw data into information managers can act on.

SNHU's catalog says the course explores how BI applications improve management effectiveness through better decision-making, discusses the benefits and appropriate uses of BI, and has students use current BI tools to build realistic solutions. Current trends, including the growing role of big data, are also discussed.

The prerequisites tell you what the course expects: CIS-255 Applied Data Structure and Database, plus one statistics course (MAT-240 Applied Statistics or MAT-241 Modern Statistics with Software). The challenge is combining all three skills, data handling, basic statistics and clear business communication, in one piece of work.

What CIS-355 Covers

Key Concepts Explained

Facts and Dimensions

Reporting data is often arranged as a star schema. A central fact table holds measurable events (sales amounts, quantities), and dimension tables describe them (date, product, store, customer). This layout makes slicing data by any dimension simple.

Choosing a KPI

A good KPI is tied to a goal, measurable from available data and understood by the person who acts on it. Vanity numbers that rise without saying anything about performance do not help decisions.

From Chart to Decision

Every visual should answer a question. A line chart suits trends over time, a bar chart suits comparisons between categories, and a single highlighted number suits a headline KPI. Pair each with one sentence on what it means for the business.

Typical Assignments and How to Approach Them

Structuring a BI Scenario Paper

Scenario papers in a BI course usually ask you to show how business intelligence would support a particular organization. Markers look for a clear line from business question to data to insight to action.

• Business question: state the decision the organization faces, for example where to open a new store or why customer churn rose.
• Data sources: name the internal and external data needed and any quality problems you expect.
• Method: describe the preparation, measures and visuals, and why each suits the question.
• Findings: report what the analysis shows, with the visuals that support it.
• Recommendation and limits: say what the manager should do and what the data cannot tell them.

Noting limitations, such as missing data or a short time period, strengthens rather than weakens the paper, because it shows you understand how far the evidence goes.

Where Students Get Stuck

• Messy data. Inconsistent dates, duplicates and blanks break calculations; clean first and document what you changed.
• Too many charts. A crowded dashboard hides the message. Fewer, purposeful visuals score better.
• Statistics without context. Averages can mislead when data is skewed; consider medians and distributions.
• Missing recommendations. BI is about decisions, so end with what the manager should do.

Study Tips for CIS-355

• Revisit joins and GROUP BY from CIS-255; much BI preparation is the same logic in a different tool.
• Keep a log of each data cleaning step so you can explain and repeat it.
• Test your dashboard on someone who has not seen the data: can they state the main finding in ten seconds?
