object relational mapping — (programming, database) (ORM) The software development activity that defines a correspondence between objects in a program and rows in a database table. Atomic object properties correspond to columns in the table, non-atomic data types and relations between objects are represented as foreign keys referring to other tables. An object persistence mechanism is responsible for maintaining the correspondence between objects and the database contents at run-time.
of someone's acquaintance — A person of your acquaintance is someone who you have met and know.
office of war information — OWI.
on the big/small etc side — If you say that something is on the small side, you are saying politely that you think it is slightly too small. If you say that someone is on the young side, you are saying politely that you think they are slightly too young.
permanent virtual circuit — (networking) (PVC, or in ATM terminology, "Permanent Virtual Connection") A virtual circuit that is permanently established, saving the time associated with circuit establishment and tear-down.
phase contrast microscope — a microscope that utilizes the phase differences of light rays transmitted by different portions of an object to create an image in which the details of the object are distinct despite their near-uniformity of refractive index.
phase-contrast microscope — a microscope that utilizes the phase differences of light rays transmitted by different portions of an object to create an image in which the details of the object are distinct despite their near-uniformity of refractive index.

property damage insurance — insurance against losses arising from damage to the property of others, as in a motor-vehicle accident.
rate monotonic scheduling — (algorithm) A means of scheduling the time allocated to periodic hard-deadline real-time users of a resource. The users are assigned priorities such that a shorter fixed period between deadlines is associated with a higher priority. Rate monotonic scheduling provides a low-overhead, reasonably resource-efficient means of guaranteeing that all users will meet their deadlines provided that certain analytical equations are satisfied during the system design. It avoids the design complexity of time-line scheduling and the overhead of dynamic approaches such as earliest-deadline scheduling.
