A Beginner’s Guide to Getting Started with Snowflake

In today’s data-driven world, having a robust, scalable, and easy-to-use data platform is crucial for businesses of all sizes. If you’ve been exploring modern data solutions, you’ve likely come across Snowflake, a cloud-based data warehousing, analytics, and data sharing platform. Designed to handle large volumes of structured and semi-structured data, Snowflake has quickly become a favorite tool for organizations aiming to unlock deeper insights from their data while controlling costs and complexity.

If you’re completely new to Snowflake, this guide will walk you through the fundamentals—what Snowflake is, why it’s popular, and how you can get started.

What is Snowflake?

At its core, Snowflake is a cloud-native data platform that separates storage from compute. Unlike traditional data warehouses that require significant up-front hardware, complex setup, and ongoing maintenance, Snowflake runs entirely on the cloud (AWS, Azure, or GCP). This means you pay only for the resources you actually use, and you can scale up or down as your data or query needs fluctuate.

Key Benefits Include:

  • Scalability: Instantly scale compute resources up or down to handle peaks in workload, then scale back to minimize costs.
  • Performance: Run complex queries efficiently with Snowflake’s highly optimized engine.
  • Ease of Use: A fully managed service means less time spent on maintenance, tuning, and capacity planning.
  • Security & Compliance: Built-in security features, encryption, and compliance certifications keep your data protected.
  • Data Sharing: Securely and seamlessly share data between organizations without having to move or copy it.

Before You Begin

Before diving into Snowflake, it’s helpful to understand a few core concepts:

  1. Warehouses: In Snowflake, a “warehouse” is a virtual cluster of compute resources. Think of it as the engine that executes your queries. You can have multiple warehouses for different workloads (e.g., one for data loading, another for analytics).
  2. Databases and Schemas: Snowflake organizes data into databases and schemas, much like a traditional relational database system. Within a database, a schema stores tables and views. This logical hierarchy helps keep your environment tidy and organized.
  3. Tables, Stages & Files: You’ll load your raw or processed data into tables. Stages (either internal or external, like Amazon S3) are used as intermediaries for loading and unloading data, ensuring you can seamlessly move data in and out.
  4. SQL Knowledge: Snowflake uses SQL as its main query language. Basic SQL proficiency goes a long way. If you’re new to SQL, brushing up on SELECT, JOIN, and GROUP BY commands will help you hit the ground running.

Getting Started Step-by-Step

Step 1: Sign Up for a Free Trial Head over to Snowflake’s website and sign up for a free trial. Once you’ve completed the registration, Snowflake provides a temporary environment with free credits so you can experiment without upfront costs.




Step 2: Choose a Cloud Provider During the setup, you’ll pick from AWS, Azure, or Google Cloud Platform. If you already have a preferred cloud provider, stick with that for easier integration. If not, choose any—the Snowflake experience remains consistent.



Step 3: Familiarize Yourself with the Web UI After signing in, you’ll find yourself in the Snowflake web interface. From here, you can explore databases, write queries, manage warehouses, and monitor usage. Take a few minutes to click around and learn where everything is.

Warehouses

In Snowflake, warehouses are virtual clusters of compute resources responsible for executing queries and performing data operations such as loading, transforming, and analyzing data. They are not physical servers but scalable, on-demand compute engines that Snowflake provides as part of its cloud architecture.


Key Features of Warehouses

  1. Compute Power: A warehouse processes SQL queries and handles tasks like data ingestion and processing.
  2. Scalability: You can easily scale warehouses up (increase size) for faster performance or down to save costs.
  3. Pay-Per-Use: Snowflake charges for warehouse usage only when it is active, enabling cost control.
  4. Multiple Warehouses: You can create multiple warehouses for different workloads, such as separating analytics, ETL (data loading), and reporting.
  5. Suspending and Resuming: Warehouses can be paused when not in use to save costs.


Why Start with Warehouses?

Warehouses are fundamental to query execution in Snowflake. Without a warehouse, you cannot run queries or perform operations because there is no compute power allocated.

In Step 4, you start with creating a warehouse because:

  1. Queries Need Compute Resources: Warehouses are required to run any SQL commands, including querying and analyzing data.
  2. Cost Control: Starting small allows you to experiment without incurring significant costs.
  3. Separation of Workloads: By creating a warehouse early, you can manage workloads (e.g., ETL vs. reporting) efficiently as you grow.

Think of a warehouse as the engine of Snowflake—creating one early ensures you have the compute power necessary to load data, explore it, and perform operations.


Step 4: Create Your First Warehouse

First, Make sure you select the AccountAdmin



Navigate to the “Admin\Warehouses” section and create a new warehouse. It only takes a few clicks. Begin with a small size—Snowflake uses a pay-as-you-go model, so starting small ensures you won’t incur unnecessary costs.






Snowflake Worksheets

In Snowflake, Worksheets are interactive environments within the Snowflake web interface where users can write, execute, and manage SQL queries. Worksheets are designed to provide an intuitive and efficient way for users to interact with their Snowflake data, analyze results, and manage resources. Let’s break this down step by step.


What is a Worksheet?

A worksheet is essentially a tab-based workspace in the Snowflake UI where you can:

  • Write SQL queries: Develop, test, and run SQL code.
  • Execute Queries: Run one query or multiple queries to interact with your Snowflake database.
  • View Query Results: See the output of your queries in an organized format.
  • Manage Warehouses: Select the compute resources (warehouses) that will execute your queries.
  • Save and Share: Save your worksheets for future use and share them with teammates.


Step 5: Creating a Worksheet

to get to worksheets, you need to select it under "Projects" as follows:


Create a New Worksheet

  • At the top of the page, click on the “+ Worksheet” button.



  • This will open a blank worksheet tab where you can start writing SQL queries.


Key Components of Snowflake Worksheets

SQL Editor The main area of a worksheet where you write and execute your SQL code. It supports syntax highlighting, query formatting, and auto-completion for SQL keywords, table names, and functions.


Query Execution You can execute SQL queries in two ways: Run the current query where your cursor is located, or run all queries within the worksheet.


Results Pane Located below the SQL Editor, the Results Pane displays query results, execution status, and export options, such as saving the output as a CSV file.


Warehouse Selector Each worksheet requires a virtual warehouse to execute queries. Warehouses provide the compute resources needed to run your workloads efficiently.


Context (Database and Schema Selector) You can set the context for your queries by choosing the database (where the data is stored), the schema (which organizes tables and views), and the role (permissions for data access).


Multiple Worksheets Snowflake allows you to open multiple worksheets simultaneously. These appear as tabs, similar to browser tabs, enabling you to switch between tasks seamlessly.


Save and Share Save your worksheets for future use and share them with teammates to collaborate effectively.

Query History Snowflake tracks all executed queries, allowing you to review, re-run, or debug past SQL commands as needed.


Step 6: Select Database

In the SQL editor, type the command "USE DATABASE ", and leave the cursor after the sapce after the word "DATABASE"

Go to the Databases tab and select the sample data one as shown below:


Select the The Database TPCH_SF1 and place its name in the editor


This will place the database name at the place of the cursor on the Editor


Now, let's view the contents of the Customer Table "SELECT * FROM " and Place the Name in the editor


Now run the query (or Ctrl + Enter) and see the results below
