Enterprise Application Integration is the regular exchange of information between applications within an enterprise. Typically, this is done through the process of data extraction (outbound) or data loading (inbound). Common tools for this job fall into the Extract-Transform-Load category. This process is managed by a scheduler (Cron, AutoSys, Maestro, etc.) and is generally referred to as "the Nightly Batch," because data transfers are typically done at close of business. EAI also refers to real-time sharing of information, as well as transaction boundaries that are imposed over multiple data flows. Common tools for this job fall into the Message Oriented Middleware (MOM) and Transaction Process Montior (TPM) categories.
