1 , System Analysis and Design Objectives: T understand the cncepts f system develpment life cycle t develp and implement a system and gain awareness regarding electrnic payment mechanisms and RFID. Curse Outcmes Upn cmpletin f the curse, students shall be able t CO: Categrize and grup different systems develped fr human and business requirements. CO: Develp the steps f SDLC fr different systems and hw t apply them t a real system. CO3: Recgnize the value f infrmatin gathering mechanisms and interactive methds. CO4: Design and develp data flw diagrams fr real systems. CO5: Cmprehend the usage f data dictinary fr analyzing data riented systems and the purpse f prcess specificatin. CO6: Design effective data capturing prcesses frm peple and systems.
