  A brief introduction of Power BI and Publishing Process
&lt;/h2&gt;

&lt;p&gt;Power BI is a business tool that has been developed for analysis by Microsoft to allow user visualization of data, create interactive reports and share some insights across an organization or company. Whereas publishing process is just sharing your report so that others can have access to it. So far learnt about Power BI Queries, DAX, data modelling, joins, charts, dashboards and reporting.&lt;/p&gt;

&lt;p&gt;Power BI consists of three main components:&lt;/p&gt;

&lt;ul&gt;
&lt;li&gt;Power BI Desktop - It is used to build reports and data models.&lt;/li&gt;
&lt;li&gt;Power BI Service - This is a cloud-based platform which is used to share, collaborate and one is able to access reports online.&lt;/li&gt;
&lt;li&gt;Power BI Mobile - These are just apps in the smartphones or tablets used for viewing dashboards.&lt;/li&gt;
&lt;/ul&gt;

&lt;h3&gt;
  
  
  Here are few steps to follow while creating workspace
&lt;/h3&gt;

&lt;p&gt;1). Create a Report &lt;/p&gt;

&lt;ul&gt;
&lt;li&gt;Ensure you have built your report in Power BI Desktop by using visuals like charts, tables and maps.&lt;/li&gt;
&lt;/ul&gt;

&lt;p&gt;2). Save the File&lt;/p&gt;

&lt;ul&gt;
&lt;li&gt;Always ensure your work is saved in (pbix format).&lt;/li&gt;
&lt;/ul&gt;

&lt;p&gt;3). Sign In&lt;/p&gt;

&lt;ul&gt;
&lt;li&gt;Log into your Power BI account (Usually through an organization or Microsoft Account).
Examples: &lt;a href="mailto:datascience@luxdevhq.com"&gt;datascience@luxdevhq.com&lt;/a&gt; or &lt;a href="mailto:johndoe@gmail.com"&gt;johndoe@gmail.com&lt;/a&gt;
&lt;/li&gt;
&lt;/ul&gt;

&lt;p&gt;4). Publish the Report&lt;/p&gt;

&lt;ul&gt;
&lt;li&gt;Click the publish button, a shade of blue at the far end on the left written Publish.&lt;/li&gt;
&lt;li&gt;Choose a destination Workspace in Power BI Service this can either be Shared Workspace for an organization or My Workspace for personal use.&lt;/li&gt;
&lt;/ul&gt;

&lt;p&gt;5). Access Power BI Service&lt;/p&gt;

&lt;ul&gt;
&lt;li&gt;Your report will be uploaded on cloud where it can be viewed in a browser.&lt;/li&gt;
&lt;/ul&gt;

&lt;p&gt;6). Share and Collaborate&lt;/p&gt;

&lt;ul&gt;
&lt;li&gt;Once the report is published you can share with colleagues via links, apps or workspace access.&lt;/li&gt;
&lt;li&gt;You can also restrict your work by choosing to make it public or private, choosing who can or cannot see it.&lt;/li&gt;
&lt;/ul&gt;

&lt;p&gt;7). Schedule Refresh&lt;/p&gt;

&lt;ul&gt;
&lt;li&gt;This is optional, you can decide to refresh your report so that it can be up to date. &lt;/li&gt;
&lt;/ul&gt;

      <title>UNDERSTANDING DATA MODELLING IN POWER BI</title>
      <dc:creator>Diana Wachenje</dc:creator>

      <guid>https://forem.com/diana_wachenje_c0bc1d1f1c/-understanding-data-modelling-in-power-bi-5hf2</guid>
      <description>&lt;h2&gt;
  
  
  Introduction
&lt;/h2&gt;

&lt;p&gt;Power BI is a business analytic platform that transforms raw data into actionable insights through visualizations and reports that helps users to analyze data, identify trends securely across organizations to make data-driven decisions.&lt;br&gt;
Data modelling is the process to connect, structure, optimize data tables to work efficiently together.&lt;/p&gt;

&lt;h3&gt;
  
  
  Concepts to Understand
&lt;/h3&gt;

&lt;ul&gt;
&lt;li&gt;&lt;p&gt;Joins&lt;br&gt;
Joins are performed in Power Query where you combine two columns by selecting the first and the second table and join them by clicking on the headers. Also ensure they have same data type for accurate matching.&lt;/p&gt;&lt;/li&gt;
&lt;li&gt;&lt;p&gt;Relationships&lt;br&gt;
Relationships define how table connect. These are,&lt;/p&gt;&lt;/li&gt;
&lt;li&gt;&lt;p&gt;One-to-Many (Most common)&lt;/p&gt;&lt;/li&gt;
&lt;li&gt;&lt;p&gt;Many-to-One&lt;/p&gt;&lt;/li&gt;
&lt;li&gt;&lt;p&gt;Many-to- Many (Used carefully)&lt;br&gt;
Example:&lt;/p&gt;&lt;/li&gt;
&lt;li&gt;&lt;p&gt;One customer- Many Sales&lt;/p&gt;&lt;/li&gt;
&lt;li&gt;&lt;p&gt;Schemas&lt;br&gt;
Schemas refers to the way your data is structured either in facts tables or dimensions and organized in the data model.&lt;/p&gt;&lt;/li&gt;
&lt;li&gt;&lt;p&gt;One Central fact table&lt;/p&gt;&lt;/li&gt;
&lt;li&gt;&lt;p&gt;Multiple surrounding dimension tables&lt;/p&gt;&lt;/li&gt;
&lt;/ul&gt;

&lt;h4&gt;
  
  
  Power BI Relationships
&lt;/h4&gt;

&lt;ul&gt;
&lt;li&gt; Cardinality
Cardinality is how rows relate:&lt;/li&gt;
&lt;li&gt;One-to- One&lt;/li&gt;
&lt;li&gt;One-to- Many&lt;/li&gt;
&lt;li&gt;&lt;p&gt;Many-to- Many&lt;/p&gt;&lt;/li&gt;
&lt;li&gt;&lt;p&gt;Cross Filter Direction&lt;br&gt;
It controls how filters move between tables:&lt;/p&gt;&lt;/li&gt;
&lt;li&gt;&lt;p&gt;Single direction&lt;/p&gt;&lt;/li&gt;
&lt;li&gt;&lt;p&gt;Both directions&lt;/p&gt;&lt;/li&gt;
&lt;/ul&gt;

&lt;h5&gt;
  
  
  Commonly modelling issues
&lt;/h5&gt;

&lt;ul&gt;
&lt;li&gt;Not using proper Data Table&lt;/li&gt;
&lt;li&gt;Mixing fact and dimensional data &lt;/li&gt;
&lt;li&gt;Creating too many many-to-many relationships&lt;/li&gt;
&lt;/ul&gt;

&lt;h6&gt;
  
  
  Steps-by-steps Data modeling process
&lt;/h6&gt;

&lt;p&gt;Step 1: Load Data&lt;br&gt;
Import from Excel, SQL etc.&lt;br&gt;
Step 2: Clean Data (Power Query)&lt;br&gt;
Fix structure before modelling&lt;br&gt;
Step 3: Create Relationships&lt;br&gt;
Go to model view and connect tables&lt;br&gt;
Step 4: Build Star Schema&lt;br&gt;
Organize tables properly&lt;br&gt;
Step 5: Create measures (DAX)&lt;br&gt;
Add business logic&lt;br&gt;
Step 6: Optimize Model&lt;/p&gt;

&lt;ul&gt;
&lt;li&gt;Remove unused columns&lt;/li&gt;
&lt;li&gt;Use correct data types&lt;/li&gt;
&lt;li&gt;Avoid unnecessary relationships &lt;/li&gt;
&lt;/ul&gt;

&lt;h6&gt;
  
  
  # Simple Real-life Examples
&lt;/h6&gt;

&lt;p&gt;In a mini mart setup:&lt;/p&gt;

&lt;ul&gt;
&lt;li&gt;Sales table- transactions &lt;/li&gt;
&lt;li&gt;Product table- item details&lt;/li&gt;
&lt;li&gt;Customer table- buyer information&lt;/li&gt;
&lt;/ul&gt;

&lt;h6&gt;
  
  
  ## Why Data Modelling is important
&lt;/h6&gt;

&lt;ul&gt;
&lt;li&gt;Faster reports&lt;/li&gt;
&lt;li&gt;Accurate Insights
-Easier Dashboards&lt;/li&gt;
&lt;/ul&gt;
