This challenge is faced by too many people… But there is light at the end of this black hole of data… See how our heroine, Amanda Lee managed to solve this challenge.

We take you on a captivating journey with Amanda, an employee who faced a daunting challenge: analyzing complex data from SAP.

Her determination, resourcefulness, and expertise in SQL, Excel, and Power BI led her to become a valued data analyst within her organization.

Let’s delve into the Case Study of Amanda and explore the transformative power of these tools, and how Amanda managed to survive the day and thrive…

The SAP Data Conundrum:

Amanda, a dedicated employee known for her analytical skills, was tasked by her manager to analyze data from SAP, the company’s backbone for managing vital business information.

The data was available in multiple places in some standard reports, and some custom reports.Data in multiple silos can be combined with Power BI, SQL, Python. Learn how to do this at Intellisoft Courses in Singapore.

But the manager wanted a perfect report, and it was difficult to make sense of the whole, big picture from multiple sections.

So Amanda was tasked to take this challenge and make it work.

The challenge lay in finding a single report that provided a comprehensive overview of the required data. Undeterred, Amanda set out to conquer this data conundrum.

Exploring Standard Reports:

Amanda embarked on a meticulous exploration of SAP’s standard reports, hoping to find the perfect report or a solution.

She dedicated countless hours to examining various reports, seeking the elusive comprehensive data set.

However, despite her best efforts, none of the reports met the boss’s requirements.

Exporting and Excel Limitations:

Not one to give up easily, Amanda decided to export the data from SAP Reports into Excel, believing it would allow her to manage and analyze the information more effectively.

To her dismay, the exported data turned out to be massive, exceeding the limits of Excel’s capabilities. It became evident that relying solely on Excel would not suffice to solve this complex data puzzle.

Plus, loading multiple huge report files, and other Master data files at the same time caused her computer to crash often.

Excel and the Power of VLOOKUP:

Determined to find a solution, Amanda delved deeper into Excel’s functionalities and discovered the power of VLOOKUP.

She realized that by merging data from multiple sources, she could create a more comprehensive dataset. This process, however, proved to be laborious and error-prone, requiring significant time and effort to align the data properly.

Learning VLOOKUP is one thing, and applying it to lookup multiple codes & descriptions from multiple sheets and multiple Excel files was too cumbersome and slow.

Discovering SQL:

Driven by her desire for efficiency, Amanda set out on a quest to find a more robust solution. She began exploring the world of databases and stumbled upon SQL (Structured Query Language).

Recognizing its potential in handling large datasets and performing complex queries, Amanda dedicated to mastering SQL language.

With a single SQL query, the query effortlessly pulled out the required information, bypassing the arduous process of manual data manipulation.

Amanda’s achievement in harnessing the power of SQL marked a significant turning point in her quest for analytical excellence.

Excel Dashboards and Visualizations:

With the right data finally at her disposal, Amanda exported it back into Excel, now equipped with the necessary insights.

She utilized Excel Dashboards to create various analyses and visualizations, bringing the data to life in a meaningful and impactful way.

The management was astounded by the depth of insights provided by these visualizations, realizing the untapped potential of data analysis.

Introducing Power BI:

The success achieved with Excel Dashboards paved the way for an even more remarkable transformation. Amanda was introduced to Power BI, a powerful business intelligence tool, by the Corporate HQ of the company.

She was spellbound by the dynamic, beautiful, amazing analysis capabilities of Power BI.

She began to migrate the entire solution from Excel to Power BI, creating interactive dashboards and reports that enabled the entire organization to access and explore the latest data analysis  effortlessly, from any device, without waiting for manual data refreshes and month end jobs to complete running.

Becoming the Data Analysis Expert:

Amanda’s expertise in SQL, Excel, and Power BI elevated her to a coveted position within the company.

She became the go-to analyst for senior management, constantly engaging in discussions and providing innovative solutions to analyze and visualize information for the leadership team.

Her journey from an individual contributor to a key player in shaping data-driven decisions exemplified the transformative power of mastering these tools.

What is SQL & Why You Should Learn It

Learn SQL to query any database quickly in Singapore
SQL training in Singapore
SQL training in Singapore

SQL stands for Structured Query Language. It is the language used to interact with any RDBMS (Relational Database Management System) like Oracle, SQL Server, MySQL, PostgreSQL.

Attending a SQL training course will teach you how to query SQL databases, step by step. The most common types of requests are where you want to pick out some rows or records from a database table. You want to analyze data yourself.

To extract the data from any database, we can write a SELECT query, to extract that data from the table within the database.

A single table SQL query is pretty easy to write. It almost reads like English. You can qualify which columns you want, and what you want to filter out, based on your criteria.

Once you execute the query, the results from the database are picked up and displayed almost instantly. Retrieval of SQL data from a database is usually extremely fast.

A multiple-table SQL query requires you to understand the relationships between the different tables within the database, the primary key and secondary keys of the various tables, and then carefully do the joining of the common fields between the different tables.

Once the common fields are linked between the tables, a data model is created. The common fields help to essentially create a long flat row, where you can pick any columns (or field) from any table in the combined row. This is the power of SQL. It is the reason almost everyone wants to learn SQL.

Multiple table queries are more useful, and they are similar to writing multiple VLOOKUPs in Excel to get to the Master & Transaction data in a single row.

Writing Multiple table SQL queries is where most people get stuck… because of the various ways to join – right join, left join, inner join, outer join etc.

This is where attending a SQL Training Course comes in handy. By joining a short 2 day SQL workshop, you can understand the fundamentals of SQL.

You will be able to do use these SQL Commands after attending a SQL workshop in Singapore:

  • How to insert data into a database table with the SQL INSERT statement,
  • how to delete records from any table by writing a SQL DELETE statement.
  • how to modify any data in any table within the SQL Database using the UPDATE statemet,
  • how to retrieve any number of columns from a single or multiple related tables, based on any selection criteria, with the SELECT SQL Statement.

If you can attend a classroom training course for SQL, I would seriously recommend it. The reason is that in a Classroom SQL Course, you can ask questions on the spot, and there is an expert SQL trainer to assist you too.

Check out our SQL Training Course in Singapore for Classroom Training

In our most popular SQL course in Singapore, we cover SQL statements like SELECT, INSERT, UPDATE, DELETE, CREATE TABLE, CREATE INDEX, CREATE VIEW, DROP, JOINS, and much more.

SQL is a very standard language, simple & business-like. It is like talking to someone in English. Pretty simple & straightforward. And it does not feel like learning a new language. It is pretty intuitive and easy to learn. A two day SQL workshop is more than sufficient to get you going on your journey to pick any data from your corporate databases.

A standard SQL based on the American National Standards Institute ANSI is best because you can then apply the standard SQL on any ANSI Relational Database.

The version of SQL is not really important, as most modern SQL database systems are up to date with the latest ANSI standards.

Using SQL, you are no longer at the mercy of the IT programmers to extract certain reports for you. You also do not have to be satisfied with the run of the mill standard reports coming out of the systems.

Most systems provide basic transnational reports, but when you want to go beyond, customize them or tweak them, you realize that it is simply not possible.
