THis work demands an expert in relational databases. The case study is similar to the one below. This is urgent and only those who are EXCELLENT should bid please. IF YOU DONT HAVE FEEDBACK PLEASE DONT BID, AS I HAVE A BAD EXPERIENCE BEFORE Melanie and John are the proprietors of Premiertech Conferences, a conference org. buz in Melbourne's eastern suburbs. Since 1985, PC has been a major provider of information and education in network technologies through annual conf. in Mel.,bringing together the world's leading authorities on strategic technologies and key topics such as globalisation and technology. PC organizes each individual conf. via its own conferencing system. the computerised conferencing system currently provides prospective presenters and delegates with information about a particular conf, arranges for them to register for the conf.,book accomodation, and book for the conf. dinner. PC is a completely computerised company. HOwever, recent trends and new delegates requirements have placed demands on their computerised conf information system which it cannot cuurently support. these new demands include higher delegate expectations of svc, and additional conf facilities. Description of Operations and Problems PC books a conf venue for each conf, and arranges dates and times fo the conf, which typically last 3 days. Sharon and Jon have now recognized the need to arrange several presenters and delegates through brochures and other media. Sharon and John organize several keynote speakers to attend each conference, and details of those apper in the promotion material. within the conference promotion material, a request is issued for potential additional presenters to submit presentation proposals, in the form of printed draft papers submitted to Melanie or JOhn.
