(c) all collisions enact at the client sites.The promise ‘client/server’ refers principally to an construction, or close opposition of responsibilities , the client is the collision (besides notorious as the frontend), and the server is the DBMS (besides notorious as the backend). 4. EXTERNAL INTERFACE REQUIREMENTS 4. 1 USER INTERFACES ? Frontend software: Vb. net account ? Backend software: SQL+ 4. 2 HARDWARE INTERFACES ? Windows XP. ?

OTHER NONFUNCTIONAL REQUIRMENTS 5. 1 PERFORMANCE REQIREMENTS The steps implicated to execute the utensilation of airline facts medium are as inventoryed beneath. A)E-R DIAGRAM E-R Diagram institute a technique for delineateing the close constituency of a factsmedium in a picturesque process.This partition is then used to adregular facts as a homogeneity, typicalizing homogeneity and finally obtaining a homogeneity factsbase. ENTITIES : Which indicate detached real-earth items in an collision. PROPERTIES/ATTRIBUTES : Which indicate properties of an existence and homogeneityships. RELATIONSHIPS : Which coalesce entities and delineate mediumingful dependencies among them. B) NORMALIZATION : The basic external of typicalization is to be curtail congeries which instrument that notification is to be stored singly unintermittently. Storing notification distinct spells leads to wastage of storage quantity and acception in the whole dimension of the facts stored. If a Datamedium is not uprightly adapted it can gives stir to qualification anomalies.
