CompTIA Data+ (DA0-002)

Course Description

CompTIA Data+ (DA0-002) develops practical capability to collect, prepare, analyze, visualize, govern, and communicate data using the DA0-002 competency areas. The learning path begins with data concepts, structures, architecture, and business requirements and acquisition, profiling, cleansing, transformation, and quality, connecting technical or business decisions to measurable outcomes, security, evidence quality, and operational responsibility.

Applied work is framed around a business analytics team combining operational, customer, financial, and service data for recurring decisions. Learners then progress through descriptive analysis, statistics, queries, and interpretation and visualization, reporting, governance, privacy, and stakeholder delivery, producing data requirement and architecture map, prepared dataset and quality exception log, analysis notebook and interpretation record, and validated dashboard and governance checklist.

By completion, participants can plan, implement, validate, troubleshoot, communicate, and hand over the course workflows with clear assumptions, tests, corrective actions, rollback points, ownership, and prioritized next steps.
