What is a data platform: Understanding its key components
A data platform is a technology environment designed to collect, store, manage, and analyze data. It’s a place where data is brought together from multiple sources and is made available to users like data scientists, analysts, and business teams who can then extract insights from the data to inform decision-making or to create data-driven products.
Here are some key elements that define a data platform:
- Data collection and ingestion
- Data storage and management
- Data processing and transformation
- Data analysis and visualization
- Scalability and performance
- Security and compliance
- Interoperability and flexibility
Now, let us look into each of the above key elements in brief:

The platform provider must ensure the platform’s robustness, scalability, and security, while the developers and users rely on the platform to build, deploy, and operate their data-driven applications and services. The success of the platform provider is tied to the success of the users and developers, creating a symbiotic relationship.
What is a data platform architecture? Understanding it with a schematic representation
A data platform architecture refers to the underlying structure and layout of a data platform, which consists of various technologies, tools, and methodologies to collect, process, store, manage, and analyze data.
A data platform architecture is generally built around the following components:
- Data ingestion: This is the process by which data is collected or imported into the data platform. It could be real-time data (streaming) or batch data. Tools like Apache Kafka, Amazon Kinesis, or Google Pub/Sub are used for real-time data ingestion, while ETL (Extract, Transform, Load)tools like Talend, Informatica, or AWS Glue are used for batch data ingestion.
- Data storage: This is where the data resides after it is collected. It could be in a data warehouse (like Amazon Redshift, Google BigQuery, or Snowflake), a database (like MySQL, PostgreSQL, or MongoDB), or a data lake (like Amazon S3, Azure Data Lake Store, or Google Cloud Storage).
- Data processing: This is the act of transforming and cleaning the raw data into a form that can be used for analysis. It could involve data normalization, aggregation, and other kinds of data transformation.
- Data management: Data needs to be managed for consistency, reliability, and compliance. This involves data governance, metadata management, data lineage, and data security. Tools like Atlan could be used for data governance and metadata management and data lineage.
- Data analysis and visualization: The processed data is analyzed and visualized using tools like Tableau, Looker, PowerBI, or programming languages like Python or R for custom analysis.
- Data science and machine learning: The platform may include a suite of machine learning tools for predictive modeling, clustering, recommendation, etc. This could involve platforms like Databricks, Google AI Platform, or AWS SageMaker.
- Infrastructure: This could be on-premises, cloud-based (like AWS, Azure, Google Cloud), or hybrid. It defines where the actual hardware and software resources that power the platform reside.
These components are connected together in a way that allows for secure, reliable, and efficient flow and processing of data from the point of ingestion to the point of consumption (like a dashboard or report). The architecture is also designed to be scalable to handle growing data volumes and complex workloads. The exact design and technologies used in a data platform architecture will depend on the specific needs and goals of the organization.
Data platform architecture schematic representation
A data platform consists of several interconnected components that work together to collect, store, process, analyze, and visualize data. In this section, let us explore the key components of a data platform and how they help in data-driven decisions.
A textual schematic could look something similar to this:
[Data Sources] --> [Data Ingestion] --> [Data Storage] --> [Data Processing] --> [Data Analysis] --> [Data Visualization] | | | | | (Collects data) (Secures & stores) (Transforms data) (Analyzes data) (Visualizes results) | | | | | v v v v v (Raw Data) (Stored Data) (Processed Data) (Insights/Patterns) (Reports/Dashboards)
Let us understand each of the components in the above schema:
- Data sources
These are the original sources of data, which can include databases, APIs, files, streams, or even real-time data from IoT devices.

Traditional data platform vs. modern data platform: Their evolution and what makes them different
Traditional data platforms, characterized by structured and centralized approaches, relied on relational databases and data warehouses. However, as data volumes, velocity, and variety increased, these platforms faced limitations in handling big data, real-time processing, and unstructured data.
That led to the emergence of modern data platforms that offer enhanced capabilities to meet the demands of today’s data-rich environments. In this section, we will explore the differences between traditional and modern data platforms:
Traditional data platforms
In the past, traditional data platforms typically followed a structured and centralized approach. They primarily consisted of relational databases and data warehouses. These systems were designed to handle structured data and were often on-premises, meaning they were physically located within the organization.
- Relational databases
These databases use a schema to define data relationships, and data must be structured to fit this schema. Examples include MySQL, Oracle Database, and SQL Server.
- Data warehouses
Data warehouses are used for reporting and data analysis. They are optimized to process large amounts of data and support complex queries.
However, traditional data platforms had limitations. They struggled with large volumes of data (what we now call “big data”), they weren’t built to handle real-time data processing, and they didn’t support unstructured data well, which makes up a large portion of modern data (e.g., text, images, videos).
Modern data platforms
Modern data platforms have evolved to overcome these limitations and support the diverse needs of today’s data-rich environments. They have the ability to handle enormous volumes of data, process data in real-time, and manage both structured and unstructured data. Furthermore, they often leverage cloud technologies for scalability, flexibility, and cost-effectiveness.
- Big data technologies
Tools like Hadoop and Apache Spark allow for distributed processing of large data sets across clusters of computers.
- Data lakes
Data lakes store data in its raw format, supporting structured, semi-structured, and unstructured data. They provide flexibility as the need for pre-defined schemas is eliminated or reduced.
- NoSQL databases
NoSQL databases are designed to handle unstructured data, scale horizontally, and support real-time processing. They can store and retrieve data that is modeled in means other than the tabular relations used in relational databases.
- Real-time processing
Tools like Apache Kafka and Apache Flink allow for real-time data ingestion and processing.
- Cloud-based services
Modern data platforms often leverage cloud-based services for storage, processing, and analysis. Examples include Snowflake, Google BigQuery, AWS Redshift, and Azure Data Lake Storage.
- Machine learning and AI
Modern platforms often incorporate machine learning and AI capabilities, making it easier to build and deploy predictive models.
- Data governance and security
With the increasing importance of data privacy and protection, modern platforms incorporate advanced data governance and security features.
While modern data platforms provide many advantages, they also introduce complexity due to the variety of tools and technologies involved. Therefore, organizations need to carefully consider their specific needs and capabilities when designing their data platforms.
Traditional data platform vs. modern data platform: A tabular view
Here is a comparison between traditional and modern data platforms in a tabular format:
|Feature||Traditional Data Platform||Modern Data Platform|
|Data Type||Primarily structured data||Structured, semi-structured, and unstructured data|
|Data Volume||Limited; struggles with large volumes ("big data")||Handles very large volumes of data ("big data")|
|Data Processing||Batch processing; struggles with real-time processing||Both batch and real-time processing|

In the table above, we have provided you a general comparison. But, the specific capabilities and characteristics can vary based on the tools and technologies used in the data platform.
Data platform vs database: Uncovering their differences
While a database and a data platform both deal with data, they serve different purposes and operate on different levels of complexity.
Database: A database is essentially a structured set of data. It’s a place to store, manage, and retrieve data efficiently.
- A database can be used to hold tables of data, relationships between them, views, indexes, and procedures.
- Examples include SQL databases like MySQL, PostgreSQL, or Oracle, and NoSQL databases like MongoDB or Cassandra.
- Databases usually offer capabilities like transactions, allowing multiple operations to be treated as a single unit of work.
Data platform: Like we defined above, a data platform is an architecture or environment that houses not only databases but also other components necessary for storing, processing, and analyzing large volumes of structured, semi-structured, and unstructured data.
- A data platform may encompass data ingestion tools, data storage (like databases, data warehouses, and data lakes), data processing engines, analytics and business intelligence tools, and often machine learning capabilities.
- It also includes data governance and security mechanisms.
- Examples include big data platforms like Amazon Web Services, Microsoft Azure, and Google Cloud Platform.
In simple terms, a database can be considered as one component or a building block of a data platform. A data platform not only stores data (in databases, data lakes, or data warehouses) but also provides various capabilities to process, analyze, and gain insights from this data.
