Power BI Architecture Overview: The Potential of Data in Manufacturing

In BI, data are the building blocks of meaningful insights. From sales figures to production metrics, data represent the details that reveal trends, performance, and areas for improvement. For Power BI, data are the lifeblood that fuels the entire BI process, allowing you to generate reports, monitor key metrics, and predict future outcomes. Without correct data, BI insights lose value. This is why data integrity, structure, and accessibility are essential.

In the context of Power BI, the data come from diverse sources—databases, apps, cloud services, or even Excel spreadsheets. Each data source contributes a piece of the puzzle, providing the foundational information that you can later transform into visual, actionable insights.

Power BI’s architecture organizes data processing into several phases. Each phase prepares the data for analysis and reporting, allowing you to create reliable insights at each stage of the BI process.

Power BI starts by connecting to a variety of data sources, from cloud services like Azure, AWS, web APIs, and Google Analytics to on-premises databases. This flexibility allows manufacturers to gather insights from multiple operational systems—ERP, CRM, supply chain management systems, and more.

In the practice, a manufacturing company would connect Power BI to its ERP system to access production and inventory data, giving leaders a real-time view of stock levels and manufacturing efficiency.

Power Query, Power BI’s ETL (Extract, Transform, Load) tool, helps you clean, structure, transform, and model data to make it usable. In this phase, you can filter irrelevant data, fill in missing values, and create new calculated fields.

For example, a manager in a manufacturing firm may use Power Query to filter out irrelevant time periods, ensuring they only analyze data from the most recent production cycles.

Once the data is transformed and ready for analysis, Power BI Desktop allows you to create reports with visualizations tailored to specific questions or metrics. From line charts to heat maps, Power BI’s visual tools help you see patterns and outliers at a glance.

A typical example involves a plant manager comparing a monthly production output vs. machine downtime visuals, enabling the team to identify patterns and optimize maintenance schedules.

Reports can then be combined into dashboards that provide an overview of key metrics. This is particularly valuable for C-level executives who need to monitor KPIs in real-time without diving into detailed reports.

Normally, a plant manager will have a dashboard displaying real-time data on production efficiency, employee performance, and safety incidents, providing a quick overview of the plant’s health.

Power BI’s architecture is composed of several key components, each playing a specific role in the BI process. Here’s a breakdown of each one:

Power BI can connect to a wide array of data sources, providing unmatched flexibility for businesses to bring in all types of information. These data sources range from cloud platforms (like Azure, AWS, Snowflake, and Salesforce) to on-premises databases (SQL Server, Oracle) and even simple Excel spreadsheets.

For manufacturing, this means Power BI can integrate data from production systems, ERP, and inventory management software into one centralized platform, ensuring that decision-makers have a comprehensive view of operations.

Power BI uses connectors for each source, which act as translators, making it possible for diverse systems to “speak the same language” when delivering data. This connectivity ensures data accuracy, completeness, and up-to-the-minute relevance, which are crucial for generating insights that lead to actionable decisions.

Power Query is Power BI’s ETL (Extract, Transform, Load) engine, a fundamental tool in the architecture. It allows users to pull raw data from sources, clean it, and shape it into a usable format—all without advanced coding. The ETL process is divided as follows:

Power Query is invaluable in manufacturing, where raw data often arrives in complex formats. With Power Query, manufacturing leaders can transform scattered production data into insights that highlight efficiency, find bottlenecks, and inform production planning.

The Data Model is the structural backbone of Power BI, where data tables are related in ways that support complex analysis. Using a star schema model, Power BI establishes relationships between different tables, making it easier to conduct multi-dimensional analysis. This structure allows for dynamic queries and calculations that respond to specific business questions.

For instance, a manufacturing company might have separate tables for inventory, production schedules, and sales orders. The Data Model would link these tables so that executives can easily track how production aligns with sales demand, allowing for adjustments to prevent overproduction or stockouts.

Data modeling not only improves analysis accuracy but also streamlines report creation, as users don’t need to repeatedly process and structure data for each report.

Power BI Desktop is the primary tool with which users can build data models, design reports, and create visualizations. Its drag-and-drop interface makes it user-friendly, while its robust features allow for in-depth data manipulation and customization.

Power BI Desktop provides:

In manufacturing, Power BI Desktop enables engineers and analysts to create reports that visualize meaningful production KPIs, monitor OEE and downtime, and track defect rates.

Power BI Service is a cloud-based platform that allows users to share, publish, and collaborate on reports and dashboards. Unlike Power BI Desktop, which is mainly used to create reports, Power BI Service focuses on accessibility and collaboration, ensuring that data-driven insights are always at hand for decision-makers, even on the go.

Power BI Service offers:

For executives in manufacturing, this means they can review real-time data on production performance and make quick, informed adjustments from anywhere, enhancing decision-making speed and efficiency.

Power BI Gateway acts as a bridge between on-premises data sources and Power BI’s cloud environment. This gateway is crucial for manufacturing companies with sensitive data stored on local servers rather than the cloud.

With Power BI Gateway, manufacturers can securely access critical on-premises data, such as production metrics and inventory levels, from the Power BI Servicewithout compromising data security.

Power BI Report Server is a solution for organizations that prefer to keep their reports and data on-premises. This server-based option provides Power BI flexibility but within an internal server.

Key features include:

In the manufacturing industry, where data privacy and control are critical, Power BI Report Server ensures that insights stay within company walls, maintaining data security while still offering rich BI capabilities.

Power BI Mobile brings data accessibility to smartphones and tablets, allowing managers and executives to monitor KPIs on the go. With the Power BI app, users can access dashboards and reports optimized for mobile consumption, complete with interactive visuals.

For example, a plant manager can check production metrics from their phone during a facility inspection, allowing them to make on-the-spot decisions. Power BI Mobile supports real-time monitoring, so executives have access to the latest information, even if they’re away from their desks.

DAX, or Data Analysis Expressions, is the formula language in Power BI that enables users to create custom calculations and metrics. DAX allows for advanced data manipulation that goes beyond basic arithmetic, enabling complex calculations that reveal deeper insights. 

In manufacturing, DAX can be used to calculate metrics like:

DAX empowers manufacturing analysts to tailor calculations to their unique KPIs, enabling a customized BI experience that aligns with their specific operational needs.

Row-Level Security (RLS) is a security feature that restricts data access based on user roles, ensuring that employees only see data relevant to their position. RLS enhances security by allowing organizations to implement access rules that meet both compliance requirements and internal data privacy standards.

For instance, a manufacturing organization might use RLS to restrict access to financial data, allowing only finance and executive teams to view it. Meanwhile, production managers can access data relevant to their departments, ensuring that sensitive information stays protected.

The Power BI API provides a programming interface that enables organizations to customize Power BI, integrating it with other systems and automating specific tasks. The API allows developers to create custom applications, embed reports, and automate the deployment of dashboards.

For manufacturing companies, the Power BI API can automate data updates, ensuring that reports always show the most current data without manual intervention. It can also be used to embed Power BI visuals into internal applications, streamlining data visibility and enhancing the user experience.

Power BI Embedded is a feature that allows companies to incorporate Power BI’s reporting and visualization tools into their own applications. This capability makes it possible for manufacturing companies to share insights with customers, partners, or stakeholders without requiring them to log into Power BI separately.

For example, a manufacturing company might embed a Power BI dashboard into a customer portal, allowing clients to track their order status or view production timelines. This provides customers with direct access to relevant data, improving transparency and customer satisfaction.

Power BI works through two primary layers: the front-end and the back-end.

The front-end, including Power BI Desktop and Power BI Service, is where users interact with data. This is where reports are built, dashboards are viewed, and data-driven decisions are made

The back-end handles data transformation, modeling, and storage. Power Query and the data model form the backbone of Power BI’s data management capabilities, ensuring that data is organized and prepared for analysis.

Power BI offers role-based security options that allow organizations to control who accesses specific data. Through Row-Level Security, Power BI administrators can assign roles, limiting access to sensitive information.

In this case, for example, supervisors will only see data related to their specific lines, while plant managers and executives have access to a higher-level view of all operations.
