Key Characteristics of the Modern Data Stack

To understand what sets the modern data stack apart, let’s examine its defining characteristics:

  • Cloud-first: Modern data stack tools are designed to leverage cloud infrastructure, offering scalability, elasticity, and ease of integration with existing cloud services.
  • Built around cloud data warehouses/lakes: The central component is typically a cloud data warehouse (e.g. Snowflake, BigQuery) or data lake, optimized for analytics workloads.
  • Modular design: Components can be easily swapped or upgraded without disrupting the entire system, providing flexibility as needs evolve.
  • Open-source friendly: Many tools in the stack are open-source, fostering innovation and community support.
  • SaaS and managed services: Commercial distributions often offer low-code or no-code interfaces, reducing the need for specialized technical expertise.
  • Data democratization: The stack promotes wider data access and self-service analytics capabilities across the organization.
As we delve deeper into the components that make up the modern data stack, it’s essential to understand how each element contributes to a holistic data management strategy that empowers organizations to harness their data effectively.

Modern Data Stack Architecture

The architecture of the modern data stack is designed to streamline the flow of data from sources to insights, providing a coherent structure that enhances efficiency and collaboration within organizations. At a high level, this architecture typically consists of several key components. Let’s dive into the top 8 components that make up a typical modern data stack:

1. Data Sources

The journey begins with data sources – the various systems and applications generating raw data. These can include:

  • Databases (SQL and NoSQL)
  • SaaS applications (e.g. Salesforce, Zendesk)
  • Web and mobile applications
  • IoT devices and sensors
  • Event streams
  • External APIs

Peliqan offers connectivity to over 100+ SaaS applications, files, and databases, making it easy to bring all your business data together in one place

2. Data Integration

To make sense of data from disparate sources, it needs to be consolidated. This is where data integration tools come in. Modern data integration follows the ELT (Extract, Load, Transform) approach:

  • Extract: Data is pulled from source systems.
  • Load: Raw data is loaded into the central data warehouse or lake.
  • Transform: Data is transformed within the warehouse for analysis.

Peliqan provides one-click ETL from any source, automatically creating and maintaining data pipelines that require zero maintenance. It also offers real-time access to external databases through its federated query engine.

3. Data Storage

The central repository in the modern data stack is typically a cloud data warehouse or data lake. These systems are designed to handle massive volumes of data and provide fast query performance for analytics workloads.

Peliqan offers a built-in data warehouse, but also supports integration with popular cloud data warehouses like Snowflake, BigQuery, Redshift, and SQL Server. This flexibility allows organizations to choose the storage solution that best fits their needs.

4. Data Transformation

Once data is centralized, it often requires further processing to make it suitable for analysis. This is where data transformation tools come in. They allow data teams to clean, restructure, and model data within the warehouse.

Peliqan provides multiple ways to transform data:

  • SQL models for data analysts
  • A spreadsheet-like interface for business users
  • Low-code Python scripts for developers

This flexibility ensures that users of all technical levels can work with and transform data effectively.

5. Data Analytics and Business Intelligence

With clean, transformed data available in the warehouse, the next step is to extract insights and visualize the data. Modern BI tools allow users across the organization to create dashboards, reports, and perform ad-hoc analysis.

Peliqan integrates with popular BI tools and also offers a built-in spreadsheet BI interface for business users. Additionally, it provides one-click deployment of tools like Metabase and Apache Superset, allowing organizations to quickly set up powerful BI capabilities.

6. Data Science and Machine Learning

For more advanced analytics, the modern data stack incorporates tools for data science and machine learning. These enable organizations to build predictive models, perform complex statistical analyses, and leverage AI capabilities.

Peliqan supports data science workflows through its low-code Python scripting environment and one-click deployment of Jupyter notebooks. It also features an AI assistant that can help generate SQL queries based on natural language questions, making it easier for non-technical users to derive insights from data.

7. Data Orchestration

To tie all these components together and ensure smooth data flows, orchestration tools are essential. They manage the scheduling and execution of data pipelines, handling dependencies and error recovery.

While Peliqan automates much of the data pipeline process, it also offers one-click deployment of Apache Airflow for users who need more advanced orchestration capabilities.

8. Data Governance and Observability

As data becomes a critical asset, ensuring its quality, security, and compliance is paramount. Modern data stacks incorporate tools for:

  • Data cataloging and metadata management
  • Data quality monitoring
  • Access control and security
  • Lineage tracking
  • Compliance management

Peliqan addresses these needs with its built-in data lineage and data catalog features. It automatically detects table and column lineage across the entire data stack, providing visibility into how data flows and transforms throughout the system.

Modern Data Stack Benefits

As we explore the numerous advantages of adopting a modern data stack, it’s essential to understand how each component contributes to a more efficient and effective data strategy.

  • Improved Decision-Making: By centralizing and transforming data, organizations can access real-time insights, enabling better and faster decision-making across all levels of the business.
  • Scalability and Flexibility: The modular nature of modern data stacks allows businesses to easily scale their data operations and adapt to changing needs, ensuring they stay competitive in a fast-paced environment.
