If you are just getting started with Power BI, understanding the key terms will help you navigate the platform more effectively. Here are the top 10 Power BI terms every new user should know:

1) Dataset

A dataset in Power BI refers to information that has been imported from Excel, SQL or cloud services. Reports and dashboards can only be created by first having the necessary datasets. They save everything, including the raw data and the designs, relationships, measures and calculated columns we’ve built in Power BI. Creating, handling and updating datasets are basic skills needed because data push in analytics, give instant business insights and bind different data sources.

2) Report

A Power BI report is made up of charts, graphs and tables, all built from data in a dataset. With reports, we have an interactive tool to explore your notes, click deeper and review additional information. Every report page is designed to communicate a certain story or point out a specific part of your data. To ensure your organization makes good decisions, it helps to know how to create and customize reports.

3) Dashboard

The dashboard in Power BI are a grouping of visual components and metrics. It gives a general and joined-up look at important observations, unlike reports that just provide a detailed view of each report or group of data. They offer business leaders an easy way to monitor and check business KPIs at any time. Managers and executives benefit from dashboards, since they can get the needed performance updates without going through many detailed reports.

4) Visualization

A visualization in Power BI presents the data using images. It is sometimes known as a visual or chart. Bar charts, pie charts, line graphs, maps, tables and similar options are part of visualizations. They change difficult-to-read information into clear graphics that can show trends, unusual values and details quickly. With Power BI, users have many ways to change how the visualizations look for their organization. To make exciting reports and dashboards, we should learn to use visualizations well.

5) Measure

In Power BI, measures are calculations designed to study data, and we can build them using DAX (Data Analysis Expressions). Unlike regular columns, measures can refresh their values at any time based on reports or what a user selects. It is easy to find the total, average, ratio, percentage and complex groups with measures. Working on efficient measures helps we turn your data into useful insights and boosts your analytical skills within Power BI.

6) Calculated Column

To create a calculated column, we add a DAX formula to some input fields in your data. We can add new information to your data using calculated columns such as grouping, marking special items or defining values for ourselves. Unlike measures, these columns are evaluated when the data refreshes rather than at query time. Having calculated columns in our data model ensures that your reports become richer and better fit your company’s specific needs.

7) Filter

We can narrow the data in your charts and graphs using filters in Power BI. They can be used at the report, page or graphical levels. Using filters, we can narrow down your analysis to a particular time, type or area of the business. Additional options available include slicers, filters for dates and filters for moving down to the next page. Adding the right filters makes your reports more relevant, so stakeholders can easily spot the main insights.

8) Data Model

Any Power BI project depends on a solid data model as its core structure. It shows the connections between data tables by using relationships, Primary Keys and Foreign Keys. In addition, the data model has calculated columns, measures and hierarchies to organize your data for use properly.

With a proper data model in place, our analysis results are correct, queries are fast, and your visualizations are easy to interact with. To create stable and scalable Power BI projects, one must learn about modelling.

9) DAX is Data Analysis Expressions

Power BI provides DAX as a language for creating your calculations in measures, calculated columns and tables. DAX has functions, operators and values that make it possible to create advanced rules for a business.

When we master DAX, we can use analytics for many purposes, including complex grouping, analyzing time and transforming the data. Knowing the basics of DAX will help new Power BI users make the most of the product’s reporting capabilities.

10) Power Query

The purpose of Power Query is to prepare your data for use in Power BI. The platform enables users to bring data from various locations, clean it, format it and transform it before it enters the data model. An easy-to-use interface and the M language in Power Query make it simple to merge, filter duplicates, organize columns and fill out repetitive tasks on the table. By using Power Query, it becomes smoother to ETL your data and it is always accurate and easy to analyze.

Conclusion

2-SAT Problem in C++

The 2-SAT problem involves determining if a given Boolean formula, consisting of variables and clauses with exactly two literals per clause, is satisfiable. In C++, it can be solved using graph theory, specifically by constructing an implication graph and checking for strongly connected components (SCCs). If any variable and its negation belong to the same SCC, the formula is unsatisfiable. Tarjan’s or Kosaraju’s algorithm is often used for SCC detection.

Wilson's Theorem in C++

Wilson's Theorem states that for a prime number pp, (p−1)!≡−1 (mod p)(p - 1)! \equiv -1 \ (\text{mod} \ p). In C++, we can implement this theorem by calculating the factorial of p−1p - 1 and then finding its remainder when divided by pp. If the result is -1, pp is prime. The theorem is often used in primality testing algorithms.
