Azure Data Fundamentals: Lessons & Preparation Route
Short lessons, worked examples, and practice that connects.
Search lessons, illustrated explanations and study references within this exam.
Data representations
Classify the actual representation and preserve the information relationships that matter.
Files,databases,and storage fit
Choose a representation and storage role by reader,update and processing requirements.
Transactional and analytical work
Separate live record changes,historical analysis and ACID properties by the question being asked.
Task-based data roles
Route work by its affected data layer without assuming one person can hold only one role.
Relational tables, keys, SQL and objects
Trace rows and keys, explain why normalization reduces duplicated facts, and read a small SQL query without confusing the output with the stored data.
Relational Azure service boundaries
Separate database and instance features,engine compatibility and guest OS control.
Object,file and key/attribute storage
Compare required operations and protocols before treating services as substitutes.
Cosmos DB API and partition boundaries
Keep document flexibility,client API compatibility and transaction scope separate.
Ingestion and analytical data stores
Trace data from source through processing,storage and analytical outputs.
Batch and streaming reasoning
Separate arrival pattern,ingestion buffering,computation and output timing.
Power BI models and visual choices
Match the analytical question,model roles and visual to the actual variables.
Normalize the fact, then check the SQL result
Identify which entity owns a fact, enumerate join outputs, and separate row counts from non-NULL value counts.
Service contracts and transaction boundaries
Separate client compatibility, host responsibility, partition scope and version-aware updates.
Analytical grain, timing and platform evidence
Test output grain, event clocks and shared platform capabilities with explicit counterexamples.
