Study Notes

Microsoft Dataverse Tables and Columns

  • Dataverse instances have standard tables with predefined columns
  • Developers can select and populate standard tables with external data
  • Custom tables can be created if standard tables aren't suitable and can be renamed for better organization.
  • The 'New table' dialog box allows developers to specify table type and ownership.
  • Activity tables manage tasks like appointments, supporting calendar entries
  • Table ownership can be at the user/team level (user-controlled access) or organization level (organization-controlled access).
  • Activity tables are by default user/team owned.
  • Standard tables have standard columns, which can be numerous per table.
  • Columns contain specific data types (e.g., Multiline Text, Whole Number, Date & Time, Phone).
  • Developers can add custom columns as needed, using the 'Add column' feature.

Relationships Between Tables

  • Data can be organized in multiple tables for better structure, especially in complex apps.
  • Relationships between tables (invoice and products, for example) are often one-to-many (1:N) or many-to-one (N:1).
  • Lookup fields define many-to-one relationships.
  • Many-to-many (N:N) peer relationships are also supported in Dataverse.
  • The Relationships tab shows existing relationships between tables, enabling developers to add new relationships.

Standard Tables (People, Places, and Things)

  • Standard Dataverse tables store business data (e.g., Account, Address, Contact, User, Task).
  • These tables cover common business needs.
  • Tables have columns tailored to the data they store.
  • Standard tables are editable and customizable, allowing developers to add/modify columns.

Business Logic with Dataverse

  • Business logic is implemented through rules, workflows, and actions.
  • Business rules manage data conditions and actions.
  • Conditions define when actions occur, based on if conditions are true or false.
  • Actions can perform tasks like setting values, clearing fields, and validating data input.
  • Actions can also show, hide, enable, disable fields, useful for forms or apps.
  • Business rules handle 'if' statements (IF [condition] THEN [action]).
  • Real-time workflows automate processes (e.g., creating, updating, assigning records) with no user interaction. They follow stages and steps. Background workflows run automatically.
  • Actions/custom process actions are similar to workflows, enabling custom messages for complex steps.

Dataflows in Power Apps

  • Dataflows gather, transform, and store data from multiple sources.
  • Data can be stored in Dataverse tables or Azure Data Lake Storage.
  • Dataflows can be refreshed periodically.
  • Shared dataflows make data easily accessible to different app components.

Solutions Management

  • Solutions package changes to the Dataverse (customizations).
  • They include Power Apps components (apps, flows, connectors) but not business data.
  • Solutions can be unmanaged (for development/editable), or managed (for deployment, not editable).
  • Unmanaged solutions can be exported as managed solutions for final implementation.
  • Solutions manage application lifecycles and processes.
