MBS (MIMAS) / MIS533 / Deploying IT Resources
Course Objective
This course deals with planning, developing and managing database environments. It
will introduce students to the ways in which database management systems (DBMS) can
support the management of data/information.
MBS (MIMAS) / MIS533 / Deploying IT Resources
Topics covered
• SAD methodologies • Infrastructure planning • Strategic dimension of data management• Requirements analysis and systems design• Process modelling • Data modelling • Enterprise systems• Database development (MS Access and Oracle).

Assessment dates
• A practical exam (20%) which will be the development of a small database from a business scenario – For example, system to support administration of Cork
Film Festival
– Scenario to be distributed by 17th November 2005
– Deadline 8th December 2005
• An MCQ (20%) on the 28th February 2006

Definitons : Analysis & Design
• Analysis : what users need the system to do
• Design : how the system will meet the need
MBS (MIMAS) / MIS533 / Deploying IT Resources
Understanding requirements
• Why do we need information systems?• Reduces possibility of error (eg. same seat not
allocated to 2 passengers)
• Volume of information (eg. all possible flights and connections)
• Speed of transaction (eg. immediate confirmation at point of sale)
MBS (MIMAS) / MIS533 / Deploying IT Resources
Background to SA & SD
• Output Oriented
• Process oriented : DFD’s
• Data-Oriented (ERD’s)
MBS (MIMAS) / MIS533 / Deploying IT Resources
What’s the best approach?
• Failings of these methods– Maintenance
• Lack of flexibility
• Resilience
• Quality
– Re-usability of code– Backlog (visible and invisible)
MBS (MIMAS) / MIS533 / Deploying IT Resources
What is Systems development
Systems development refers to all activities that go into producing an IS solution :– Systems Analysis
– Modeling
– Design
– Implementation
– Testing
– Maintenance
MBS (MIMAS) / MIS533 / Deploying IT Resources
What is so difficult about Analysis and Design?
• It involves listening, understanding, documenting and clarifying
• It takes time, patience and humility
• It works best within a framework (methodology)
• Design always influenced by experience
MBS (MIMAS) / MIS533 / Deploying IT Resources
Bad systems design
• SNCF : ticketing system
• Bank of Ireland on-line (what direct debits are on my account?)
• ERP systems: getting reports out
• Your own examples?

Understanding requirements ...
• Analysing problems– Functional decomposition– Process specification– Flow Charts– Use case– Activity diagrams
• Designing solutions– Data flow diagrams– Entity relationship model
MBS (MIMAS) / MIS533 / Deploying IT Resources
Building a model
• Functional decomposition
• Data Flow Diagram– Context diagram
– Processes
– Data Flow
– Data store
– External entities

Example : www.RyanAir.com
• Input :– Flight details (eg. SNN-BVA, 8 Oct, 10.35)– Credit card details (eg. VISA no, Expiry date)
• Process :– Confirms price (eg. EUR 79)– Makes reservation & processes payment
• Output :– Reservation reference (eg.CGHKCA)
