        Predictive models based on math
        Different types of testing to find essential variables and outliers
        Statistical tools such as Microsoft Excel, software, etc.
        Interactive displays like charts, graphs, dashboards, scorecards
        Predicting old data


When data is analyzed using these ways, it gives significant results, which can be utilized by essential decision makers like company management, stakeholders, etc. to devise smart business strategies.
There are several reasons why learning business analytics will be beneficial for business management students in the future:

You Make Better Decisions Immediately 

Numerous students pursuing a business management program aim to achieve managerial positions as quickly as possible in the future. This is not only due to higher pay of managers in comparison to entry-level positions, but also since they have the right to take decisions that will have an enormous impact on the company they will work for. However, being able to make crucial business decisions also means you are at risk of significant consequences that the organization may not have prepared for.
The reasons why lousy business decisions are made are because of the attitudes of the managers themselves. They choose faultily out of:

        Sticking to old company strategies
        Performing impudently based on the wrong insights
        Not being cautious about the details


Business analytics solve all these issues by showing managers data-driven evidence on why traditional business tactics will not work anymore, what aspects were neglected in their previous decisions, and how wrong insights were poorly implemented.

You Can Come Out With Revolutionary Ideas

Examining data in newer ways may give you fresh ideas and perspectives. In a research conducted by Google, 64% of the interviewed people believed that first; data was making businesses breaking their traditional boundaries. Second, non-traditional organizations are able to disrupt the industry and succeed. Business analytics assists marketers to become more creative by informing them of new trends based on customer behavior and data and provide them with different techniques of testing their ideas.


You Are Warned About Problems Faster

Experts on how to start a business repeatedly state how ignorance will be the collapse of any company. Problems will occur in an organization without being observed because its people don’t have the resources to warn them of these problems when they are still small.
Business analytics have a solution for all these issues. It alerts you to the problems by examining adverse changes in your organization. Displays like dashboards and KPI metrics, ensure that employees are performing to their fullest.



A business analytics program from a top-quality institution can help you in gaining the insight which will help you in making crucial business decisions in the future. Premier institutions have quality faculty and resources to facilitate your learning procedure.

Role of Apache Spark in Big Data

Apache Spark has appeared as a much handier and compelling substitute for Hadoop. Apache Spark, like all other advanced Big Data tools, is really powerful and well-equipped for dealing with enormous datasets efficiently.


What is Apache Spark?

Spark is a general-purpose data handling and the processing tool that is appropriate for use in a range of situations. Data scientists utilize Apache Spark to enhance their questioning and analysis and also for the transformation of data. Tasks which are most frequently completed using Spark comprise interactive queries across huge data sets, examination, and processing of streaming data from sensors and other sources, and also from machine learning tasks.

What Does Spark Do?

Spark is capable of processing petabytes of data at a time. This data is disseminated across a collection of thousands of cooperating servers –virtual or physical. Apache spark comes with a broad set of libraries and API which support all the generally used languages such as R, Python, and Scala.

Some distinctive use cases of Apache Spark comprise:

Spark streaming and processing: Nowadays, managing “streams” of data is a real challenge for any data expert. This data comes, often from many sources and all at one time. While one way to store this data is- in disks and analyze it retrospectively, this would cost organizations huge. Streams of financial data, for instance, can be processed in real-time to recognize—and refuse—potentially false transactions. Apache Spark helps with this precisely.

Machine learning: With the growing volume of data, ML approaches are also becoming much more accurate and feasible. Today, the software can be taught to recognize and act upon triggers and then apply similar solutions to new and unknown data. Apache Spark’s unique feature of keeping data in-memory aids in quicker querying and therefore makes it an outstanding choice for training ML algorithms.

Interactive streaming analytics: Data scientists and business analysts want to examine their data by asking a question. They no longer wish to work with pre-defined inquiries to produce static dashboards of sales, production-line productivity, or stock prices. This collaborating query process needs systems like Spark that is able to reply quickly.

Data integration: Data is created by a range of sources and is rarely clean. ETL (Extract, transform, load) processes are often done to pull data from diverse systems, clean it, standardize it, and then stock it into a distinct system for analysis. Spark is progressively being used to decrease the cost and time essential for this.

Apache spark certification from a premier institute can help you learn the essentials of this domain quickly. Top institutions have the right resources and faculty to facilitate students’ learning.
