Core Challenges

Slow SQL Database Data Retrieval 

The main challenge at first was getting data straight into the Power BI report from the SQL database. Because there were many sophisticated queries and large amounts of data, the procedure was performed slowly. To address the issue of slow data retrieval, a pipeline was created to integrate data from the SQL database into Direct Lake. 

Migration to Lakehouse Architecture 

This required building SQL views and adding capabilities like schema enforcement, indexing, and query optimization to turn the current data lake into a Lakehouse.

Data Modelling 

The limitations of the current views and the restrictions imposed by the data structures that were provided made it difficult to implement additional modelling.

Overcoming Issues with Large Data Sizes using Fabric License Solutions 

We decided to use a fabric license as a solution to the problem caused by the massive data size. We were able to handle and analyse massive amounts of data successfully once this solution addressed the problem. 

Optimal Schema Selection for Data Models 

The applicability of the star and snowflake schemas is counsel to clients while developing data models. We guarantee customized, functional data models by coordinating the choice of schema with report requirements.

Optimizing Data Models using Date Filtering  

The date/time structure of the date table and the large amount of data in the previous data model delayed the data filtering process. We suggested that the date part in the date column be shown only (with the time set to 00:00:00) to resolve issue. This increased the speed and expedited the data filtering process. 

Complexity of utilizing DAX Functions with Direct Query

Using Data Analysis Expressions (DAX) functions might be difficult when utilizing Direct Query mode, even though it provides real-time access to data

Modern Lakehouse Architecture

Centralized Data Management System

As part of the transition to a Lakehouse architecture, we leveraged data from the OneLake Datahub. Our aim was to centralize all business data. This approach simplified data access and improved governance. It created a single source of truth for enterprise-wide analytics.

Optimized Data Modelling & Query Performance

We transformed the current data lake into a Lakehouse by implementing SQL views, query optimization, indexing, and schema enforcement. Data modelling challenges within Medialab entities were resolved through a structured approach. This ensured that high-performance datasets were optimized for Power BI reporting.

Interactive Analytics & User Experience

Real-Time Reporting with Direct Query

Power BI reports were built using DirectQuery mode. This led to real-time data analysis directly from the Lakehouse without duplication or caching. It made way for up-to-date insights. At the same time, it maintained data integrity and reduced storage overhead.

Flexible Dashboards & Embedded Analytics

Interactive dashboards with drag-and-drop capabilities allow users to easily reorganize charts and visual elements. No layouts are disrupted during this. Reports are seamlessly embedded into websites and applications using Power BI Embedded. This allows users to access rich, interactive analytics within their existing workflows.

Integration

Equipped with a variety of data source. 

A wide range of integration options are available in Power BI to improve its functionality and compatibility with different tools and applications. To create this report, we have leveraged the following integration capabilities

  • SQL Server
  • Azure Services (Azure SQL Database, Azure Analysis Services)
  • Python
  • Lakehouse and Warehouse (Fabric Integration)
  • Notebook

Enhancement by adding useful features.

Drill Down

Users can view related line charts instantaneously by clicking on primary chart points, which facilitates diving down

Top N

Add a "Top N" function to table visuals to improve data visibility. This enables users to concentrate on the top N things according to predetermined criteria.

Page Navigation

Make navigating between charts easy by using dropdown menus or obvious back buttons.  

Button and Tooltip

Add interactive buttons to visualizations to give consumers choices they can take action on. Better yet, include tooltips to help users comprehend button operation and provide contextual information.

Built-in Format Capabilities

"Bring to Front" feature makes it possible to precisely align shapes over card images, guaranteeing a professional and uniform formatting.

Sync- Slicers

Users can coordinate the slicer choices across several report pages in Power BI by using Sync Slicers. With this functionality, users can filter a report consistently across several pages by selecting the same value in one synchronised slicer, which is simultaneously selected in other synchronised slicers as well.

Single Sign-on (SSO)

Installed an integrated Single Sign-On authentication system, enabling users to log into several applications with just one set of login credentials.

Scheduled Data Refresh

This report's implementation of periodic data refresh guarantees that the data is updated on a regular basis, preserving its relevance and accuracy.

Customized UI

To increase accessibility and functionality, this required improving the visual layout, including clear navigation components, and maximizing interactive features.

Key Performance Indicators

Integrated a wide range of KPIs to systematically evaluate and enhance the productivity, and overall performance of healthcare practices.
