Abstract: A method for data-centric networked application development includes: modifying a graphical user interface of a networked application development environment with a selectable component for including a reusable data entity in a project, the reusable data entity being defined and bound to a form component via interaction with the graphical user interface; and configuring a block of a data-centric form of the project with the form component in response to selection of the selectable component at a design surface of the graphical user interface.

Abstract: The present invention relates to an apparatus for measuring a compound using a photo-ionization detector. The apparatus comprises: an ultra violet (UV) lamp (10) which is filled with a krypton gas as an inert gas and emits UV light of 10.6 eV; a photo-ionization detector (PID) unit (100) which detects a compound (50) ionized by the UV lamp; a delay unit (200) which delays the compound (50) ionized through the PID unit so as to change the ionized compound into the original compound; and a collection unit (300) for collecting the compound (50) outputted through the delay unit. Accordingly, the PID unit is connected through the delay unit to the collection unit so that the compound which is quantitatively analyzed by the PID unit can be grasped in detail by the collection unit.
