Data analytical skills are important whether you are aspiring to become a data scientist or simply a student or a professional specializing a different field but somehow needs to deal with a large chunk of data. This page is the ideal place to start learning the basics about database programming and how to manipulate a massive amount of data using our platform. The steps below will first introduce you to SQL Lab and the basic functions you need to know to start using our platform effectively.
The SQL Editor
The SQL editor is a powerful tool that allows you to type SQL commands, build and run queries, create and edit your data, visualize results, and many others.
Accessing Public and Private Datasets
If you are a new user, you will see an untitled query tab on the left side of the page. Below the tab are configuration options which allow you to choose a database and dataset. A public schema dataset is uploaded by default for your convenience. It is composed of public datasets which you can use as a reference. However, the schema is read-only so you cannot make any changes to it.
You also have access to your own dataset repository under your private schema username where you will have full privileges, such as reading or editing your datasets. Under your private schema, you are given the freedom to move data from other schemas or upload your own CSV file.
Running the SQL Query
Next to the configuration sidebar is a workspace where you can type SQL queries. You can start with basic commands such as SELECT, FROM, WHERE, GROUP BY and ORDER BY. We will learn more about this in the next tutorial. For now, it is enough for you to familiarize the functionality of the SQL editor.
Visualizing Your Dataset
You can also have the option to visualize data and turn them into meaningful graphs.
Saving a CSV File
Now you have the CSV file saved in your folder, you should be able to open it using a compatible program installed on your computer (such as MS Excel) to view your dataset.

If you’re a professional in the workforce, you’ve probably seen a cultural shift towards making data-driven decisions. If you’re a student, you’ve probably seen new classes teaching business and marketing majors new data analytical tools and coding languages. You don’t need us to convince you that new skills and capabilities are needed to stay competitive in the workforce, especially in business and marketing functions.
But which skills or capability do I need to learn to stay competitive? It’s been said that engineers have the technical skills necessary to analyze the data but don’t know how to ask the right questions. Business professionals ask the right questions but don’t know how to analyze the vast amount of data. The ideal case is to obviously find a person that can ask the right business questions and analyze the data.
So, again, which skills or capabilities do I need to learn? Almost all data these days are stored in a database. So you can learn any tool that can take data out of the database and analyze it. But most common tool/language is SQL but there are also other tools out there like python, R, and Tableau. Once the data is out of the database, you’ll need to put on your business hat to analyze the dataset in a meaningful way.
We have some guides to help you along your journey. You should get started right away!
Here are the some reasons why understanding databases and having data analytical skills are useful in business analytics:
Easily Access and Manipulate Data
As more and more data come on your way, there’s no better option than having a database system. Here, you can just pull out the specific information you need from a vast ocean of data. Simply type a query to get what you need – sounds more convenient, right? An SQL database keeps your data organized and speed up data processing. Having a database management system definitely makes your life easier!
Analyze Data with Only A Few Commands
There’s no easier way to analyze trends than visualizing them with colorful details! By adding the parameters you need and setting up the graphics command, your data instantly comes to life. In business, understanding trends is very important. You will be updated with new insights and come up with wiser decisions for your business operations.
Help You Support Prototyping, Data Management, and Reporting
With the advancement of technology, a lot of systems being used in businesses today are already automated. A few basic skills in SQL will help you understand the data and provide you the information you want to extract from the system. This in return makes it easier for you to create analysis and reports, as well as build prototypes for your projects or case studies.
More Opportunities in the Business World

In the business world, data is everything. We use data to help us understand the market and our customer. Successful businesses are data-driven and integrate their data-driven decision making into their business processes. We’ve seen the continuous growth of the tech industry – think Facebook and Google – in part due to their data-driven approach to building and growing products.
Data itself has been democratized. Companies collect vast amounts of internal and external data. Data engineering and science teams are formed to help turn data into insights, and it’s becoming apparent that if you want to stay competitive in your career, you will need to develop enough technical capabilities to analyze large amounts of data using sophisticated and powerful tools beyond Excel.
How does a non-technical business and marketing professional build powerful analytical skills? Most books and tools are written by engineers for engineers. We, at Strata Scratch, understand this problem. It’s impossible to find resources tailored to the non-technical professionals – there are no tools easy enough for novices; there are no guides and exercises written for business and marketing professionals that also leverage these powerful tools.
We hope to help the new business and marketing professionals. We have a tool easy enough for non-technical novices to use, with SQL and Python guides and exercises tailored to the business and marketing professional.
