Learn Access Database Concepts and Office Data Integrity
Model information as related records
Start by identifying the entities in a process and the fields that describe each one. A primary key identifies a record; a foreign key connects it to a related table. Separating repeated details can reduce inconsistent edits and make relationships easier to query.
Protect data quality
Use suitable field types, required values, validation rules, and unique identifiers. Check for duplicates and missing relationships before reporting. Sample records should be synthetic during practice, and any real office data must remain within approved access and retention rules.
Choose the right tool for the job
A spreadsheet is useful for flexible analysis and small, controlled datasets. A database is a better fit when records have relationships, multiple users, or stronger consistency requirements. Consider the number of users, permissions, backup, and support needs before selecting a tool.
Practice task
Design a small fictional request register with separate requester and request tables. Identify primary and foreign keys, define required fields, and list checks for duplicates and missing relationships.
