WHAT IS SNOWFLAKES?

Snowflake is a cloud-based data warehousing platform that is built on top of Snowflake’s data warehouse as a service (DWaaS) engine. It allows users to create and share analytics reports, dashboards and data visualizations of the open-source technology stack, Amazon Web Services (AWS).

Snowflake provides a simple, secure way to manage and access your data, whether you’re an individual or a large enterprise. of Amazon Web Services. It provides you with all the tools needed to build a scalable data warehouse and to connect it with your applications and analytics tools of Amazon Web Services (AWS). It allows users to store, query and analyze data using simple drag-and-drop features.

There are two main ways you can use Snowflake. You can use it as a cloud-hosted data warehouse that allows you to store and analyze large amounts of data, or you can use it as a cloud-based ETL (extract, transform and load) service that simplifies the process of moving data between multiple systems. It provides you with all the tools needed to build a scalable data warehouse and connect it with your applications and analytics tools of Amazon Web Services (AWS). It allows users to store, query and analyze data using simple drag-and-drop features.

While it’s not a self-service platform, you can use its web interface to build queries and reports for your data warehouse. It also offers integration with Amazon Redshift, Amazon Athena and Amazon Quick Sight. It also provides you with a cloud-based environment where you can run your queries, visualize data and create reports. You can easily share your data warehouse with others so that they can view, refresh and add their own data to it.

SNOWFLAKES KEY FEATURES

  • Standard and Extended SQL support : It supports both Standard and Extended SQL, which means it can be used by developers with any existing database skills. It also means that if you’re already using an existing database system, you won’t have to re-train staff or learn a new syntax when switching over.
  • Command Line Interface : It has a Command Line Interface (CLI) that makes it easy to get started and provides access to many of the same features that you’d find in a traditional database management system. This means that you can use Snowflake without having to learn any new tools or syntaxes.
  • Rich Set of Client connectors : It has a rich set of client connectors, including Java, .NET and Python. This makes it easy for developers to integrate Snowflake into their existing applications or use it as the back-end for new systems. It also means that you can use the same languages that you’re already familiar with when working with databases.
  • Bulk Loading and Unloading Data : It has a number of features that make it easy to load and unload large datasets. This includes support for bulk loading data using Amazon S3, as well as the ability to connect directly with any application that can send data over TCP/IP. Snowflake makes it easy to load and unload data, which can be useful if you want to move large amounts of information from one location to another without having to do it manually. This feature is especially helpful if your company has a lot of data that needs to be transferred on a regular basis.
  • Advanced Analytics Capabilities : Snowflake offers some advanced analytics capabilities that allow users to perform complex calculations on their datasets while still keeping them in the cloud.

What is a Data Warehouse?

  • The Snowflake data warehouse is a cloud-based, massively parallel processing (MPP) platform that enables you to ingest, store and analyze massive amounts of data.
  • It can help you run queries on petabytes of information in seconds so you can make timely decisions based on the most current data available. The Snowflake platform provides tools for building your own custom applications that work with the data warehouse or connect directly to the database itself.
  • Snowflake is a cloud-based data warehouse that’s built for the modern enterprise. It provides you with the security, flexibility, and control of your own on-premise solution, but without the hassle or expense of managing hardware infrastructure.
  • You can access all your data in one place—no matter where it lives—and use it to make faster decisions. Snowflake is a cloud-based data warehouse service that provides fast, scalable and secure storage for your data.
  • It enables you to run complex queries across all your data sources, including internal systems and third-party platforms like Salesforce, Oracle or SAP. Snowflake also gives you access to advanced analytics capabilities such as machine learning and natural language processing (NLP).
  • Snowflake is a cloud-based data warehouse that makes it easy to ingest, store, manage and analyze large amounts of data. It’s built for modern workloads and can scale up or down as needed, so you don’t need to worry about overpaying for infrastructure that sits idle most of the time. You can also run standard SQL queries against Snowflake through its user interface or with Python or R scripts in the cloud.
  • Snowflake is a great choice for enterprises that want to move their data warehouse off-premises, but it’s also suitable for smaller companies that want to analyze external data sets. It supports most major databases including Oracle, PostgreSQL and MySQL, plus it has an open application programming interface (API) so you can integrate with existing applications.

How to connect SnowFlakes

to other systems : Snowflake’s data warehouse can be connected to any system that uses SQL or NoSQL databases. It provides an API for accessing its data and supports a variety of authentication methods, including OAuth and Kerberos.

To Microsoft SQL Server: If you’re a Microsoft enterprise, you can use Snowflake’s ODBC driver to connect to your SQL Server database. This provides an easy way to access data from any application or tool that supports ODBC.

To do this, follow these steps:

1) Go to the following link and download the driver file: https://github.com/snowflakehq/snowflake-odbc-driver

2) Install the driver file by double-clicking it and following the prompts.

3) Open up Visual Studio and create a connection to your database using this code

4 ) Unzip the file and place it in the ODBC directory of your computer.

5) Install the driver on your machine.

6) Run the following command in a terminal: echo “driver={Your Snowflake ODBC Driver Path}” | sudo tee -a /etc/odbcinst.ini

7)Open a command-line window and run “snowflake-odbc-driver -v” to verify that it’s installed correctly.

8) Connect to your database using Microsoft SQL Server Management Studio or any other tool that supports ODBC drivers.

Loading Data Into Snowflakes

1) Create a new table in your database that mirrors the schema of the data you want to load. 

2) Use Snowflake’s command-line interface to load your data into the table using this syntax: schema_name.csv snowflake-loader –table [tablename] –source [sourcepath]

If you’re loading data into a new Snowflake database, you need to create an empty table with the following characteristics:

  •  It must have a column of type STRING (for example, VARCHAR(256)).
  •  This column should have the name “SID” (for example, “SID”).
  •  The value in this column should be set to a unique integer value for each row

peter#(DATALOAD)@(DEMO_DB.PUBLIC)>COPY INTO contacts;

                    FROM @csvfiles

                    PATTERN = '.*contacts0[1-4].csv.gz'

                    ON_ERROR = 'skip_file';

INTO defines where the table data to be loaded, PATTERN specifies the data files to load, and ON_ERROR informs the command when it encounters the errors.

  • If the load was successful, you can now query your table using SQL

peter#(DATALOAD)@(DEMO_DB.PUBLIC)>SELECT * FROM contacts LIMIT 10;


Staging the files :

The first step is to create the files that will be used to load data into Snowflake. This can be done using any text editor of your choice, or you can use a tool such as Microsoft Excel or Google Sheets. The only requirement is that each file contains data in comma-separated values format (CSV) with a header row containing column names.

The next step is to create a staging table for your data.

You can do this by running the following command:

-snowflake –create-staging-table [tablename] -snowflake –create-staging-table [tablename]

Once created, you will see a new table appear in the Snowflake Console: The SnowSQL Loader requires that your CSV files be staged in the correct location on your file system.

For example, if you want to load data into a table named mytable in a database named mydatabase, and the source directory is called /data/mydata , then the files would need to be staged at /data/mydata/mytable .

Before loading the data, you must move all of the files into an Amazon S3 bucket. After moving them to the Amazon S3 bucket, you can then use SnowSQL Loader to load them into Snowflake.

1) Create a folder on your computer called “csv_files”.

2) Copy the CSV files into this folder.

3) Open a terminal window and go to the directory where you have copied the CSV files with the following command: cd csv_files

Loading the Data :

1) From the command line, enter the following command:

snowload –source mytable –destination s3://mybucket/data/mydata/mytable

2) When you run this command, SnowSQL Loader will prompt you to specify a password for your Amazon S3 bucket.

3) You can leave the password blank if you want but it is highly recommended that you specify one.


SNOWFLAKES WORKING ARCHITECTURE
