    SAP-HCM/HR uses iDoc from SAP to IDM and RFC calls via JCo2/3 to set values in
    SAP and to perform queries.
    SAP-UM can use iDocs and RFC from SAP to IDM and also uses JCo2/3 to write
    to/query SAP
    SAP-Portal is unidirectional IDM to SAP and uses SPML over HTTP, AKFAIK

    JCo2/3 is also known as BAPI. If that helps.

    iDoc = Intermediate Document, a text file format to exchange data between SAP
    and external systems (actually the by far most complicated text file format
    I've ever run into.)

    RFC = Remote Function Call, SAP lingo for RPC (Remote Procedure Call) and their
    way of calling programming interfaces over network connections, usually on
    TCP/33xx.

    BAPI = Business Application Programming Interface, the endpoints SAP offers to
    connect and trigger actions

    JCo = SAP Java Connector, a Java library implementing RFC calls to SAP BAPIs.
    Provided by SAP to be used by 3rd party application like IDM. Earlier IDM shims
    used JCo version 2, all current shims are based on JCo v3.
