Frequently Asked Questions
Enterprise integration is a data challenge. So much data exists within organisations that the term Big Data now refers to the size and variety of data sources. A large volume of data existing in a variety of nonstandard formats can be of significant business value, but first, it must be integrated from multiple sources or applications. The Internet of Things (IoT) also represents a new opportunity to connect with customers and analyse useful data through everyday devices, but you must filter out the critical data that needs to go to your data centre. Web applications further add to the complexity of enterprise integration, especially when legacy applications must be integrated with a service-based architecture, like microservices.
Messaging is a way for different components in a distributed application architecture to communicate. Components can send and receive messages across different languages, compilers, and operating systems, as long as each side of the communication understands the common messaging format and protocol.
Application connectors are architectural elements that model the rules for how components interact. They are standard class connections customised for certain APIs, so they can be used to quickly integrate new end points.
SAP connectors allow the integration of different applications and technologies with SAP systems through open standards. The connectors are means for technical interoperability of SAP components (written in ABAP or ABAP objects) and other components (written in Java, C++, and Visual Basic, for example).
Data streams provide a constant flow of information that applications can add to or consume from, independent of the transmission of that data. For instance, SAP HANA, streaming analytics option, is a specialised option that processes streams of incoming event data in real time and collects and acts on this information. Smart data streaming is ideally suited for situations where data arrives as events happen and where there is value in collecting, understanding, and acting on this data right away.
Some examples of data sources that produce streams of events in real time include:
● Smart devices
● Web sites (click streams)
● IT systems (logs)
● Financial markets (prices)
● Social media
Data flows into streaming projects from various sources, typically through adapters, which connect the sources to the smart data streaming server. The streaming projects contain business logic, which they apply to the incoming data, typically in the form of continuous queries and rules. These streaming projects are entirely event-driven, turning the raw input streams into one or more derived streams that can be captured in the SAP HANA database, sent as alerts, posted to downstream applications, or streamed to live dashboards.
EIPs are collections of technology-independent solutions to common integration problems. Patterns also provide a common language for developers and application architects to describe integrations.
An API is a set of tools, definitions, and protocols for building application software. It lets your product or service communicate with other products and services without having to know how they’re implemented.
Integration platform as a service (iPaaS) delivers a cloud service for application, data, process, and service-oriented architecture (SOA) integration scenarios. It is a multitenant platform that supports cloud-to-cloud, cloud-to-on-premise, on-premise-to-on-premise, and B2B integration. It supports real-time integration and scales to meet the high-volume demands of mobile; extract, transform, and load (ETL); and electronic data interchange (EDI) environments.
An enterprise integration platform as a service (eiPaaS) is a suite of cloud services that addresses a variety of scenarios, including application and data integration, as well as some combination of process, ecosystems, mobile, AI-enabled systems, and IoT integration, as well as API management and digital integration hub capabilities.
