  1. Power Apps for business applications

    Every Power Platform decision starts with the same question: what does the business need to end up with? When the answer is an application people open and use, the service is Power Apps.

    Microsoft Power Apps is a low-code application development platform for creating custom apps that solve business problems. It supports business users without a coding background as well as professional developers who build enterprise-grade solutions.

  2. Power Apps for business applications

    Power Apps offers multiple app development approaches for different combinations of user skill, scenario complexity, and design flexibility. Its business value is the ability to match a business application need with an appropriate development approach while keeping the solution within Power Platform.

    Who is building What Power Apps offers them
    A business user with no coding background A low-code route to a real business application
    A professional developer Enterprise-grade solutions on the same platform

    That range is the point. A department lead and a development team are not handed one tool and told to cope; they are given different entry points into the same platform. So "we need a custom app" points at Power Apps whatever the skill level of the person building it.

    2 / 20

  3. Quick check

    A department needs a custom application, and the people who will build it range from a business analyst to a professional developer. Which service fits, and why?

    1. APower Automate, because a workflow can stand in for the application interface the department is asking for

      Power Automate is the choice when the requirement is repeatable work or a workflow rather than an application interface.

    2. BPower Apps, because it offers several development approaches for different skill levels

      Right. Power Apps is the low-code application platform, and it offers multiple development approaches for different combinations of skill, complexity and design flexibility.

    3. CDataverse, because tables are the app

      Dataverse organizes the business data behind an application; it does not supply the application itself.

    3 / 20

  4. Power Automate for process automation

    Microsoft Power Automate is a cloud-based process automation platform for streamlining repetitive tasks, automating workflows, and connecting applications and services without deep programming expertise.

    It can replace manual steps such as forwarding messages, copying data between systems, routing documents for approval, entering form data into databases, and running recurring reports. Every item on that list is something a person currently does by hand, on a schedule or on demand.

    4 / 20

  5. Power Automate for process automation

    Removing those manual steps frees employees for higher-value work and reduces errors associated with manual processes. The second half of that sentence is the one people forget: automation is not only faster, it is more accurate, because the copy-and-paste step that used to drop a digit is gone.

    This makes Power Automate the service to select when the central requirement is repeatable work or a workflow rather than an application interface or a data store. Listen for the verbs in a requirement — forward, copy, route, enter, run every Monday — they describe a process, not a screen.

    5 / 20

  6. Quick check

    Staff spend each morning copying form submissions into a database and emailing them onward for approval. What should lead the solution, and what is the gain?

    1. APower Apps, because the requirement is a custom interface

      A screen may well be part of the solution, but the described work is a repeatable process rather than an application interface.

    2. BPower Pages, because approvals happen on a business website

      Power Pages is the choice when the required output is a business website, which is not what this requirement asks for.

    3. CPower Automate, because the requirement is repeatable work, and removing the manual steps frees people for higher-value work and reduces errors

      Right. Copying data between systems and routing documents for approval are exactly the manual steps Power Automate replaces, and doing so frees employees for higher-value work while reducing manual errors.

    6 / 20

  7. Dataverse for organized business data

    Microsoft Dataverse is a cloud-based, low-code data platform that simplifies data storage, management, and application development. It organizes business data in tables and enriches that structure with metadata, predefined relationships, and integrated business logic.

    Dataverse lets makers focus on business problems instead of manually managing database infrastructure. There are no servers to size, patch or index before the first table exists.

    7 / 20

  8. Dataverse for organized business data

    Security is part of what you get, not a project of its own. Dataverse provides role-based access control, row-level access restrictions, and column-level security without requiring custom security code.

    Layer What it controls
    Role-based access What a role is allowed to do
    Row-level restrictions Which records a user can reach
    Column-level security Which sensitive columns a user can see

    Compare that with keeping the same records in a plain file: every one of those rules would have to be invented, written and maintained by hand.

    8 / 20

  9. Quick check

    What separates Dataverse from simply keeping the same business records in a plain data file?

    1. ATables with metadata, relationships, business logic and built-in security

      Right. Dataverse organizes data in tables enriched with metadata, predefined relationships and integrated business logic, and adds role-based, row-level and column-level security without custom security code.

    2. BDataverse renders the finished user interface and publishes it to external website visitors

      Publishing an external-facing website is the business value of Power Pages, not of the data platform underneath it.

    3. CDataverse schedules the workflows that route each record onward for approval

      Routing work onward is process automation, which is what Power Automate contributes to a solution.

  11. The Common Data Model

    You rarely have to invent the shape of a customer from scratch. The Common Data Model supplies predefined table definitions for business concepts such as accounts, contacts, products, and cases.

    Shared definitions improve consistency, reduce duplication, and make connected solutions easier to create across Microsoft products. When two teams both mean the same thing by account, their solutions can meet without a translation layer in between.

    10 / 20

  12. Quick check

    A team wants standard shapes for accounts, contacts, products and cases instead of designing each table from scratch. What supplies them?

    1. AConnectors, which package the definition of every business concept and expose it to any application that asks

      A connector packages authentication, endpoints, triggers and actions for one service; it does not define business tables.

    2. BThe Common Data Model definitions in Dataverse

      Right. The Common Data Model supplies predefined table definitions for concepts such as accounts, contacts, products and cases, which improves consistency and reduces duplication.

    3. CPower Pages, which publishes the standard definitions as a business website for the rest of the organization

      Power Pages delivers a website as a solution output rather than a shared set of table definitions.

    11 / 20

  13. Connectors for apps, flows, services, and data

    Connectors bridge Power Automate and external services. A connector encapsulates authentication, endpoint configuration, and the available triggers and actions for a specific service.

    Connector-specific actions let a cloud flow interact with the service represented by its connector. Power Apps also uses connectors so a canvas app can work with Microsoft and third-party data sources in one application.

    12 / 20

  14. Connectors for apps, flows, services, and data

    What a connector carries Why it matters
    Authentication The app or flow does not implement the sign-in itself
    Endpoint configuration The address of the service is already known
    Triggers and actions The operations that service can start or perform

    One boundary is worth stating plainly. Connectors provide integration; they do not replace the app, flow, website, or data platform that uses the connection. A connector is the bridge, never the destination.

    13 / 20

  15. Quick check

    A canvas app must read from a Microsoft service and a third-party service on the same screen. What provides that reach, and what does it not provide?

    1. AConnectors provide the integration, but not the app, flow, site or data platform itself

      Right. Power Apps uses connectors so a canvas app can work with Microsoft and third-party sources in one application, and connectors integrate rather than replace the app, flow, website or data platform.

    2. BDataverse tables provide it, by replacing each external service with a local copy of its records

      Dataverse is the organized business-data foundation; it is not a substitute for reaching the external services themselves.

    3. CA cloud flow provides it, removing any need for the app to connect

      A flow can use connectors for its own steps, but it does not remove the app's own need to connect to the sources on its screen.

    14 / 20

  16. Power Pages for websites

    Power Pages sites are website objects that can form part of a complete Power Platform solution. Plans in Power Apps can generate a solution that includes Power Pages sites alongside Dataverse tables, canvas or model-driven apps, Power Automate cloud flows, Power BI, and Copilot Studio agents.

    Choose Power Pages when the required solution output is a business website, rather than a custom app, an automated workflow, or an organized business-data foundation. The test is the word website in the requirement: everything else in the solution can already be present and a site is still missing.

    15 / 20

  17. Quick check

    A solution already has Dataverse tables, a canvas app and a cloud flow, and it still needs a supplier-facing website. What is added?

    1. AAnother canvas app, since an app is what a website is

      An app and a website are different solution outputs, and the app is already in place here.

    2. BAnother cloud flow, since a workflow can serve the pages

      A cloud flow automates a process; it does not deliver the business website the requirement is missing.

    3. CA Power Pages site, the website object that completes the solution alongside the tables, app and flow

      Right. Power Pages sites are website objects that can form part of a complete Power Platform solution alongside tables, apps and flows.

    16 / 20

  18. Selecting the service by outcome

    Choose Power Apps for a custom business application, Power Automate for a repeatable process, Dataverse for organized business data, connectors for service and data integration, and Power Pages for a business website.

    The output the business asks for The service that owns it
    A custom application Power Apps
    A repeatable process or workflow Power Automate
    Organized business data Dataverse
    Reach into another service Connectors
    A business website Power Pages

    These services can participate in one solution while retaining different responsibilities. A flow can use a connector to react to a service, an app can work with connected data, and Dataverse can provide the structured business-data foundation.

    17 / 20

  19. Quick check

    Which reading of a requirement points most reliably at the right service?

    1. AThe output the business is asking for

      Right. Each service owns a different output: an application, a repeatable process, organized data, integration, or a business website.

    2. BThe number of people who will eventually use whatever gets built in the end

      Audience size does not distinguish an application from a workflow, a data foundation or a website.

    3. CThe technical skill of whoever happens to be free to build it this quarter and next

      Power Apps already offers development approaches for different skill levels, so skill does not decide which service owns the outcome.

  21. Quick check

    Which line-up of service and responsibility is correct?

    1. APower Apps for websites, Power Pages for apps, Dataverse for integration

      Power Apps creates applications and Power Pages creates websites, and Dataverse organizes data rather than integrating services.

    2. BPower Apps for apps, Power Automate for processes, Dataverse for data, connectors for integration, Power Pages for websites

      Right. Each service keeps a distinct responsibility even when all of them appear in one solution.

    3. CConnectors for data storage, Dataverse for integration, Power Automate for interfaces, Power Apps for websites, Power Pages for processes

      Every pairing here is swapped: connectors integrate, Dataverse stores, Power Automate automates, Power Apps builds apps and Power Pages builds websites.
