Snowflake Architecture & Key Concepts for Data Warehouse
This article was published as a part of the Data Science Blogathon.
Introduction on Snowflake Architecture
This article helps to focus on an in-depth understanding of Snowflake architecture, how it stores and manages data, as well as its conceptual fragmentation concepts. By the end of this blog, you will also be able to understand how Snowflake architecture differs from all the cloud-based websites of the Massively Parallel Processing Databases.
What is a Data Warehouse?
Businesses today are full of data. The amount of data produced daily is truly amazing. With Data Explosion, it becomes increasingly difficult to capture, process, and store large or complex data sets. Therefore, it becomes necessary for organizations to have a Central Archive where all data is stored securely and can be re-analyzed to make informed decisions. This is where Data Warehouses comes into play.
The Data Warehouse, also known as the “One Source of Truth”, is a Central Database that supports the activities of Data Analytics and Business Intelligence (BI). Data Warehouses stores large amounts of data from multiple sources in one place and is intended for questioning and analysis to improve their business. Its analytical power allows organizations to obtain important business information from their data in order to improve decision-making.
What is the Snowflake Data Warehouse?
Snowflake is a cloud-based Data Warehouse solution provided as Saas (Software-as-a-Service) with full ANSI SQL support. It also has a unique structure that allows users to simply create tables and start query data with very little management or DBA tasks required. Find out about Snowflake prices here.
Features of Snowflake Data Warehouse
Let’s talk about some of the great features of Snowflake data warehouse:
1. Data Protection and Protection: Snowflake data repository provides advanced authentication by providing Multi-Factor Authentication (MFA), federal authentication and Single Login (SSO) and OAuth. communication between client and server is secured by TLS.
2. Standard and Extended SQL Support: Snowflake data repository supports multiple DDL and SQL DML commands. It also supports advanced DML, transactions, lateral views, saved processes, etc.
3. Connectivity: Snowflake Database supports a comprehensive set of client and driver connectors such as Python connector, Spark connector, Node.js driver, .NET driver, etc.
4. Data Sharing: You can securely share your data with other Snowflake accounts.

Types of Data Warehouse Architecture
There Are 3 Ways To Improve Data Warehouse:
• Single-Tier Architecture: This type of architecture aims to extract data in order to reduce the amount of data stored.
• Two-tiered Architecture: This type of architecture aims to separate the actual Data Sources from the Database. This enables Data Warehouse to expand and support multiple end users.
• Three-tiered Architecture: This type of architecture has 3 phases in it. The section below contains Data Warehouse Server Databases, an intermediate section of Online Analytical Processing (OLAP) Server used to provide a vague view of Websites, and finally, the advanced section Advanced Client Framework that includes tools and APIs used to extract data.
Components of the Database Development
The 4 components of the Data Warehouse are as follows.
1. Database Warehouse Database
The website forms an integral part of the Database. Database stores and provides access to corporate data. Amazon Redshift and Azure SQL come under cloud-based Database services.
2. Extraction, Transform, and Load (ETL) Tools
All activities associated with the extraction, conversion, and uploading (ETL) of data in a warehouse fall under this category. Traditional ETL tools are used to extract data from multiple sources, convert it to readable format, and finally upload to Data Warehouse.
Metadata provides the framework and definitions of data, allowing for the creation, storage, management, and use of data.
4. Database Access Tools
Accessibility Tools allow users to access usable and business-friendly information from Data Warehouse. These Warehouse tools include Data Reporting Tools, Data Inquiry Tools, Application Development Tools, Data Mining Tools, and OLAP Tools.
Snowflake architecture contains a combination of standard shared disk and unallocated formats to provide the best for both. Let’s go through these buildings and see how Snowflake integrates them into a new mixed-type construction.
Shared-Disk Architecture Overview
Used on a standard website, shared disk architecture has a single storage layer accessible to all cluster nodes. Many cluster nodes with CPU and Memory without disk storage themselves connect to the central storage layer for data processing and processing.
Shared-Nothing Architecture Overview
In contrast to the Shared-Disk architecture, Shared-Nothing architecture distributed cluster nodes and disk storage, its CPU, and Memory. The advantage here is that data can be categorized and stored across all cluster nodes as each cluster node has its own disk storage.
Snowflake Architecture – Hybrid Model
The snowflake supports high-level formation as shown in the diagram below. Snowflake has 3 different layers:
1. Storage Layout
2. Computer Layer
3. Cloud Services Background
1. Storage Layout
Snowflake organizes data into many smaller compartments that are internalized and compressed. Uses column format to save. Data is stored in cloud storage and acts as a shared disk model thus providing ease of data management. This ensures that users do not have to worry about data distribution across all multiple nodes in the unassigned model.
Calculation notes connect to the storage layer to download query processing data. Since the storage layer is independent, we only pay for the monthly storage amount used. As Snowflake is offered on the Cloud, storage is expandable and charged as per the monthly TB use.
2. Computer Layer
Snowflake uses the “Virtual Warehouse” (described below) to answer questions. Snowflake splits the query processing layer into disk storage. It uses queries in this layer using data from the storage layer.
Virtual Warehouses MPP compiles include multiple nodes with CPU and Memory provided in the cloud by Snowflake. Multiple Virtual Warehouses can be created on Snowflake for a variety of needs depending on the workload. Each visible warehouse can operate on a single layer of storage. Typically, the visible Warehouse has its own independent computer collection and does not interact with other warehouses.
Benefits of Virtual Warehouse
Some of the benefits of a visual warehouse are listed below:
1. Virtual Warehouses can be started or suspended at any time and can be measured at any time without the impact of effective queries.
2. They can also be set to auto-stop or restart automatically so that storage is stopped after a certain period of inactivity and when the query is sent it is restarted.
3. It can also be set to default on a smaller and larger collection size, hence e.g. we can set a minimum of 1 and a maximum of 3 so that depending on the load of Snowflake can provide between 1 to 3 bulk storage containers.
3. Cloud Services Layer
All functions such as authentication, security, uploaded metadata data management and query integration linking Snowflake across this layer occur in this layer.
Examples of services hosted in this layer:
1. If the application for entry is filed it must go through this section,
2. The query sent to Snowflake will be sent to the developer in this layer and forwarded to the Compute Layer for processing the query.
3. Metadata needed to improve query or filter data is stored in this layer.
These three layers measure independently and charge Snowflake for storage and a warehouse that looks separately. The service layer is managed within the given computer nodes, which is why it can be charged.
The advantage of this Snowflake structure is that it can measure any one layer without the other. For example. you can measure the storage layer by extension and you will be charged for storage separately. More virtual repositories can be provided and rated when additional resources are needed to quickly process queries and improve efficiency. Learn more about Snowflake buildings from here.
