Incremental Loading:Its also called retrospective data load.In this data being loaded on a regular inerval and only new data is moved.
eg in ur data warehouse ur loading "Transactional Data" on daily basis and its happning only for new Transactions because old Data is already in the Data warehouse.
Batch Processing:
Its processing of Jobs/Task together.
eg if u have a staging area u may have valid reason to get data for different Departments there first and then move all that in one shot to production.
