  We describe three real time data analysis systems implemented during the
third phase of the OGLE survey (OGLE-III). The EWS system is designed to detect
on-going microlensing events. The EEWS system monitors the microlensing
phenomena for anomalies from the single mass microlensing. The NOOS system
detects transient objects in the OGLE-III fields (SNe, microlensing events,
variable stars) that normally are below the detection threshold. Information on
objects detected by each of these systems is distributed to the astronomical
community for follow up observations. Also a short description of the OGLE-III
hardware and photometric data pipeline is presented.
