Gartner defines data integration as the discipline comprising the architectural patterns, methodologies and tools that allow organizations to achieve consistent access and delivery of data across a wide spectrum of data sources and data types to meet the data consumption requirements of business applications and end users. Data integration tools enable organizations to access, integrate, transform, process and move data that spans various endpoints and across any infrastructure to support their data integration use cases. The market for data integration tools includes vendors that offer a stand-alone software product (or products) to enable the construction and implementation of data access and data delivery infrastructure for a variety of data integration use cases.
Gartner defines integration platform as a service (iPaaS) as a vendor-managed cloud service that enables end users to implement integrations between a variety of applications, services and data sources, both internal and external to their organization. iPaaS enables end users of the platform to integrate a variety of internal and external applications, services and data sources for at least one of the three main uses of integration technology: Data consistency: The ability to monitor for or be notified by applications, services and data sources about changes, and to propagate those changes to the appropriate applications and data destinations (for example, “synchronize customer data” or “ingest into data lake”). Multistep process: The ability to implement multistep processes between applications, services and data sources (for example, to “onboard employee” or “process insurance claim”). Composite service: The ability to create composite services exposed as APIs or events and composed from existing applications, services and data sources (for example, to create a “credit check” service or to create a “generate fraud score” service). These integration processes, data pipelines, workflows, automations and composite services are most commonly created via intuitive low-code or no-code developer environments, though some vendors provide more-complex developer tooling.
