Here are some of the differences:
1. Power BI Desktop supports bi-directional cross filtering relationships, security, calculated tables, and Direct Query options.
2. Power Pivot for Excel has single direction (one to many) relationships, calculated columns only, and supports import mode only. Security roles cannot be defined in Power Pivot for Excel.

Power Pivot is an add-in for Microsoft Excel 2010 that enables you to import millions of rows of data from multiple data sources into a single Excel workbook. It lets you create relationships between heterogeneous data, create calculated columns and measures using formulas, build PivotTables and PivotCharts. You can then further analyze the data so that you can make timely business decisions without requiring IT assistance.

Below are the most important BI add-in to Excel:
* Power Query: It helps in finding, editing and loading external data.
* Power Pivot: Its mainly used for data modeling and analysis.
* Power View: It is used to design visual and interactively reports.
* Power Map: It helps to display insights on 3D Map.

Below are some of the benefits:
* By declaring and evaluating a variable, the variable can be reused multiple times in a DAX expression, thus avoiding additional queries of the source database.
* Variables can make DAX expressions more intuitive/logical to interpret.
* Variables are only scoped to their measure or query, they cannot be shared among measures, queries or be defined at the model level.
Posted Date:- 2021-09-26 22:48:28
These are the only functions that allow you modify filter context of measures or tables.
* Add to existing filter context of queries.
* Override filter context from queries.
* Remove existing filter context from queries.
* Filter parameters can only operate on a single column at a time.
* Filter parameters cannot reference a metric.
Posted Date:- 2021-09-26 22:47:06
The FILTER function returns a table with a filter condition applied for each of its source table rows. The FILTER function is rarely used in isolation, it’s generally used as a parameter to other functions such as CALCULATE.
* FILTER is an iterator and thus can negatively impact performance over large source tables.
* Complex filtering logic can be applied such as referencing a measure in a filter expression.
FILTER(MyTable,[SalesMetric] > 500)

Below are some of the most commonly used DAX function:
SUM, MIN, MAX, AVG, COUNTROWS, DISTINCTCOUNT
IF, AND, OR, SWITCH
ISBLANK, ISFILTERED, ISCROSSFILTERED
VALUES, ALL, FILTER, CALCULATE,
UNION, INTERSECT, EXCEPT, NATURALINNERJOIN, NATURALLEFTEROUTERJOIN,
GEOMEAN, MEDIAN, DATEDIFF
Posted Date:- 2021-09-26 22:44:51
To do basic calculation and data analysis on data in power pivot, we use Data Analysis Expression (DAX). It is formula language used to compute calculated column and calculated field.
* DAX works on column values.
* DAX can not modify or insert data.
* We can create calculated column and measures with DAX but we can not calculate rows using DAX.
Sample DAX formula syntax:
For the measure named Total Sales, calculate (=) the SUM of values in the [SalesAmount] column in the Sales table.

The following are the Building Blocks (or) key components of Power BI:
1. Visualizations: Visualization is a visual representation of data.
Example: Pie Chart, Line Graph, Side by Side Bar Charts, Graphical Presentation of the source data on top of Geographical Map, Tree Map, etc.
2. Datasets: Dataset is a collection of data that Power BI uses to create its visualizations.
Example: Excel sheets, Oracle or SQL server tables.
3. Reports: Report is a collection of visualizations that appear together on one or more pages.
Example: Sales by Country, State, City Report, Logistic Performance report, Profit by Products report etc.
4. Dashboards: Dashboard is single layer presentation of multiple visualizations, i.e we can integrate one or more visualizations into one page layer.
Example: Sales dashboard can have pie charts, geographical maps and bar charts.
5. Tiles: Tile is a single visualization in a report or on a dashboard.
Example: Pie Chart in Dashboard or Report.

The list of data sources for Power BI is extensive, but it can be grouped into the following:
<> Files: Data can be imported from Excel (.xlsx, xlxm), Power BI Desktop files (.pbix) and Comma Separated Value (.csv).
<> Content Packs: It is a collection of related documents or files that are stored as a group. In Power BI, there are two types of content packs, firstly those from services providers like Google Analytics, Marketo or Salesforce and secondly those created and shared by other users in your organization.
<> Connectors to databases and other datasets such as Azure SQL, Databaseand SQL, Server Analysis Services tabular data, etc.

Power BI is a cloud-based data sharing environment. Once you have developed reports using Power Query, Power Pivot and Power View, you can share your insights with your colleagues. This is where Power BI enters the equation. Power BI, which technically is an aspect of SharePoint online, lets you load Excel workbooks into the cloud and share them with a chosen group of co-workers. Not only that, but your colleagues can interact with your reports to apply filters and slicers to highlight data. They are completed by Power BI, a simple way of sharing your analysis and insights from the Microsoft cloud.

Adjustments aimed directly by a User are referred to as actions. For example, you can use an action to perform SQL Database operations such as lookup, update, and delete data. All actions will be directly mapped to Swagger operations.
Triggers: Several connectors include triggers that will notify your app when certain events occur. Consider the case of an FTP connector with the OnUpdatedFile trigger. You can create a Logic App or a flow that listens for this trigger and takes action whenever it fires.
Triggers are classified into two types.
Polling Triggers: These triggers can call your service at a specific frequency to check for new data. When new data becomes available, it will trigger a new run of your workflow instance with the data as input.
Push Triggers: Such triggers can pay any attention to data on an endpoint, which means they will wait for an event to happen. When the event occurs, your workflow instance is restarted.

A power apps canvas app lets users make their own powerapps. In powerapps, power users can select from a list of functions and choose the ones they wish to use.
The powerapps patch function is used when there are many conditions in one powerapp and if they all have to be satisfied the user has to go over all these powerapps and then use powerapps patch.
The powerapps patch function basically lets the user combine multiple powerapps into one powerapp by using an if-then statement.

Components are referred to as the reusable building blocks for canvas apps so that app makers will be allowed to create the custom controls and use them across apps. Components can either be exported and imported in different apps across organizations. The Components are helpful and allow you to build larger apps that have the same control patterns. For example, we can build a navigation control and use it across our app on different screens. Once a component is updated, all instances in the app will be reflecting your changes. Components make sure that the performance is enhanced or improved and will also help in standardizing the look and feel of PowerApps applications in an organization. A component also consists of the input properties that are capable of receiving values from the app, and the component can make use of these internally. Components also include the output properties that are capable of providing output values to the app.
