It comprises several components that work together to form a cohesive system. Here are the key components of a modern data stack architecture:
Data sources refer to the different systems and platforms from which data originates. It can come from multiple sources such as social media platforms, IoT devices, third-party data providers, internal systems such as CRM, ERP, or HR, and many more.
The value of data sources lies in their ability to equip organizations with critical insights regarding their customers, operations, and business performance. This helps companies to optimize their strategies, refine their products and services, and ultimately drive business growth.
However, collecting data from multiple sources can be challenging, as data may be stored in different formats, have varying levels of quality, or require different access methods. Therefore, modern data stack architecture typically includes tools and technologies for data integration and ingestion, which allow organizations to collect data from different sources and load it into a central repository or data warehouse.
Data integration is a critical aspect of modern data architecture, which involves the amalgamation of data from multiple sources into a cohesive and unified view. It involves a set of technologies, processes, and practices that allow organizations to combine data from diverse internal and external sources and load it into a centralized place.
By merging data from different sources, organizations can eliminate data silos, reduce redundancy, enhance data quality, and establish a single version of the truth.
Some popular tools for data integration are Fivetran, Airbyte, and Segment.
There are several approaches to data integration, including:
1. Extract, Transform, and Load (ETL): This involves extracting data from various sources, transforming it into a common format, and loading it into a target system such as a data warehouse.
2. Extract, Load, and Transform (ELT): This approach is similar to ETL, but it involves loading the data into a target system first and then transforming it. ELT can be more efficient than ETL in some scenarios because it reduces the time taken to transform the data.
3. Application Programming Interfaces (APIs): APIs enable different software applications to communicate and exchange data in real-time. This approach is ideal for organizations that need to integrate data from cloud-based applications or external data sources.
4. Data Virtualization: With data virtualization, organizations can access data from various sources without the need to physically combine it.
