The Zwicky Transient Facility is a new robotic-observing program, in which a newly engineered 600-MP digital camera with a pioneeringly large field of view, 47~square degrees, will be installed into the 48-inch Samuel Oschin Telescope at the Palomar Observatory. The camera will generate ~petabyte of raw imagery over three years of operations.  In parallel related work, new hardware and software systems are being developed to process these data in real time and build a long-term archive for the processed products.  The first public release of archived products is planned for 2018, which will include processed images and astronomical-source catalogs of the northern sky in the $g$ and $r$ bands. Source catalogs based on two different methods will be  generated for the archive: aperture photometry and point-spread-function fitting.
