Enterprise systems integration involves connecting disparate applications to produce unified functionality. There are different levels of integration maturity from point-to-point connections that require more maintenance over time, to integration tiers/middleware that standardize communication but have higher costs. The most advanced approach is service-oriented architecture (SOA) which defines services with standardized contracts to enable reuse and composite applications. Main architectural solutions for integration include message-oriented middleware with brokers, and business process management engines. Technical options cover messaging platforms and business process tools.

- 13. Main Integration Styles File Transfer – each application produce files of shared data for others to consume and consume files that others have produced. Shared Database – applications store the data they wish to share in a common database. Remote Procedure Invocation – each application expose some of its procedures so that they can be invoked remotedly, and have applications invoke those to initiate behavior and exchange data. Messaging – each application connect to a common messaging system, and exchange data and invoke behavior using messages. 13
