What does BI stand for in a business context?
Binary Increment
Business Intelligence
Business Invoicing
Business Integration
Business Intelligence refers to the strategies and technologies used by enterprises for data analysis and decision making. It encompasses data mining, process analysis, performance benchmarking, and predictive analytics. The acronym BI stands for Business Intelligence. Learn more.
Which of the following is a popular BI data visualization tool?
Dropbox
GitHub
Tableau
Slack
Tableau is a leading business intelligence tool used for data visualization and dashboard creation. It helps users transform raw data into interactive, shareable dashboards. Other tools like GitHub, Slack, and Dropbox serve different purposes. Learn more.
What is the primary purpose of a data warehouse in BI?
To manage transactional operations in real time
To host web applications and websites
To store historical business data in a central repository
To serve as an OLTP database for daily transactions
A data warehouse centralizes and stores large volumes of historical business data to support reporting and analysis. It allows for optimized query performance and data consolidation from multiple sources. It is distinct from OLTP systems designed for transaction processing. Learn more.
Which processing type is OLAP best suited for?
Simple record insertions
Data entry forms
Real-time transaction processing
Complex analytical queries
Online Analytical Processing (OLAP) systems are designed for fast retrieval of aggregated and complex analytical queries. They optimize multi-dimensional analysis rather than frequent transaction updates. OLTP systems handle transaction processing tasks. Learn more.
Which schema organizes data around fact tables and dimension tables?
Flat file schema
Snowflake schema
Star schema
Entity-relationship schema
A star schema organizes data into fact tables containing quantitative metrics and dimension tables containing descriptive attributes. It simplifies queries and improves performance in data warehousing. Snowflake schemas are normalized extensions of star schemas. Learn more.
In an ETL process, what does the 'T' represent?
Transmit
Transform
Translate
Transfer
ETL stands for Extract, Transform, Load. The 'Transform' step involves cleaning, aggregating, and converting data into a suitable format for analysis. Transformation ensures data quality and consistency before loading. Learn more.
Which chart type is most effective for showing trends over time?
Pie chart
Scatter plot
Line chart
Heat map
Line charts plot data points connected by lines, making them ideal for visualizing trends and changes over time. They clearly show progression and patterns. Other chart types are better for part-to-whole relationships or distribution. Learn more.
What is a KPI in business intelligence?
Knowledge process interface
Key process integration
Key performance indicator
Knowledge performance index
A Key Performance Indicator (KPI) is a measurable value that demonstrates how effectively an organization achieves key business objectives. KPIs help track strategy execution and performance over time. They are central to BI dashboards. Learn more.
Which normal form eliminates transitive dependencies in a relational model?
Boyce-Codd normal form
First normal form
Second normal form
Third normal form
Third normal form (3NF) requires that all attributes are functionally dependent only on the primary key, eliminating transitive dependencies. This reduces redundancy and improves data integrity. BCNF imposes stricter rules but 3NF specifically addresses transitive dependency. Learn more.
In a Slowly Changing Dimension Type 2, what happens when an attribute value changes?
No action is taken
The existing record is overwritten
The dimension table is truncated
A new record is created to track history
Type 2 Slowly Changing Dimensions track historical changes by creating a new record with the updated attribute, preserving the old record. This allows BI systems to report on data as it was at any point in time. Overwriting would lose history. Learn more.
OLAP cubes typically store data in which structure?
Multidimensional arrays
Flat files
Graph databases
XML documents
OLAP cubes store data in multidimensional arrays, allowing fast retrieval of aggregated results along multiple dimensions. This structure optimizes analytical queries. Flat files and XML are not designed for efficient OLAP operations. Learn more.
In Microsoft Analysis Services Tabular models, which in-memory analytics engine is used?
SSAS Multidimensional engine
TabularX engine
Vertex engine
xVelocity (VertiPaq)
Analysis Services Tabular models use the xVelocity (formerly VertiPaq) in-memory engine for fast columnar storage and compression. This engine enables high-speed query performance and efficient memory utilization. The Multidimensional engine is used in SSAS OLAP models. Learn more.

Cheat Sheet

  1. Data Warehousing & Schema Design -

    Review star and snowflake schemas using resources like Stanford's CS145 and Kimball Group articles to understand how dimension tables detail attributes and fact tables store measures. Master the "DDF" mnemonic - Dimensions Detail, Facts Follow - to remember table roles in a data warehouse. Proper schema design speeds query performance and is fundamental for any business intelligence test.

  2. ETL Process Fundamentals -

    Understand the Extract, Transform, Load workflow with guides from MIT OpenCourseWare and Oracle's ETL documentation, visualizing ETL like cooking: gather ingredients (Extract), prep them (Transform), then serve (Load). Practice hands-on in tools like Talend or Informatica to reinforce each step and hone your skills. This solid foundation ensures you excel on your business intelligence test and real-world projects.

  3. Interactive Reporting Tools -

    Build proficiency in Power BI, Tableau, or Looker through Microsoft Learn and Tableau Academic Programs so you can ace any business intelligence quiz or BI analyst assessment test.
