Module 3 & 4 Flashcards
Defined as the ability to deliver an integrated suite of business applications.
Example:
SAP, Oracle, Peoplesoft
Enterprise Resource Planning (ERP)
▪ If important data is captured in a given application, it must be manually entered into other applications
▪ If important data is modified in a given application, the changes will not be reflected in other applications -the changes must be entered manually
▪ If an application needs data that exists in another application, a user must manually search for that data
Business inefficiencies
The solution to the lack of communication between enterprise apps.
Enterprise Application Integration (EAI)
Most Common Enterprise Application Type:
▪ Accounting systems
▪ Automated billing systems
▪ Business analytics and intelligence platform
▪ Business continuity planning (BCP)
▪ Content management system
▪ Customer relationship management (CRM) tools
▪ Email marketing platform
▪ Enterprise resource planning (ERP)
▪ Enterprise messaging systems
▪ Payment processing
▪ Service desk application
Enterprise organizations that deploy many externally and internally facing applications need to integrate data from across those applications, ensuring that databases are synchronized and streamlining data access and availability throughout the entire organization
Data Integration
Enterprise application integration helps reduce an organization’s dependence on individual software vendors by abstracting business policies or rules from the application and into a middleware framework.
Vendor Independence
Enterprise application integration creates an opportunity for common facades that can access multiple applications.
Common Interfacing
3 Enterprise Needs for Adoption of EAI
▪ Data Integration
▪ Vendor Independence
▪ Common Interfacing
The earliest application integrations were done using this connection. A script would be used to extract data from one application, modify its structure or format, and send it to a different application.
Point-to-Point Integration
A centralized hub connects to enterprise applications, captures, and re-formats data and decides where that data should be distributed.
Hub-and-Spoke Integration
Represents an evolution of the hub-and-spoke model that runs without human interference. It uses a defined set of standards to govern the flow of data between applications, enabling any application to transmit or receive data according to the applied business rules and policies.
Bus Integration
A category of a software tool that sits between application user interfaces and operating systems.
Middleware
The current standard for enterprise applications that are deployed in the cloud. Enterprises that run their applications in the cloud can capture data from each deployed microservice and route that data to the required destinations and databases using APIs
Microservices
Five Models for Enterprise Application Integration
▪ Point-to-Point Integration
▪ Hub-and-Spoke Integration
▪ Bus Integration
▪ Middleware
▪ Microservices
