Approaching Your IS Project: A Step-by-Step Guide
- 1. Approaching your IS Project Kevin Murani BIF 4 Student Strathmore University
- 2. what, why, how so, .... what is it exactly? collecting, filtering & processing data create and distribute information
- 3. what, why, how and ... why exactly? support operations, management and decision making
- 4. what, why, how and ... how again? system analysis & design, database management, information security
- 5. how to start identify a problem or opportunity unaddressed issue, existing but lacking solution, unidentified opportunity get familiar with the background and domain this is the basis of the proposal. your idea does not exist in a vacuum know how far you can go be ambitious, but back it up. at the end of the day, you need to pass!!!
- 6. what you need to know Best practice object oriented concepts OOP relation database systems RDBMS know a few design patterns pick the right tools and the right methods this will allow you to design & build your system
- 7. always have a database some level(s) of authentication add, edit, delete, list and view report generation an efficient solution / clever approach
- 8. by example A local primary school is having a problem generating reports for it's exams. The process is painstakingly slow. Reports are required by the school, the teachers, the students and their parents. The process is manual. It's is slow, error prone and vulnerable to loss of data over time. How can we help them?
- 9. by example identify the requirements of the system what does the system need to do? 1. allow for the creation of exams 2. allow for the entry of marks 3. allow for the viewing of marks 4. generate exam reports
- 10. by example identify the actors who uses the system? 1.an administrator 2.a teacher 3.a student*
- 11. by example identify the roles who can do what? 1.an admin can manage different exams 2.a teacher can manage different marks 3.a students can view their results
- 12. by example this is obviously too general 1.log in/authentication, 2.forms for adding, 3. forms for editing, 4.forms for deleting 5.views for listing, 6.views for viewing, 7.searching features
- 13. by example ... approaching the DB Assuming you are using OO Concepts (and you should be) What is a database? collection of tables What is a table? collection of records What is a record? collection of attributes What is a class? state (attributes) + behavior (methods) how does this work?
- 14. by example ... approaching the DB each table in your database should be represented by a class in your code. a class is an instance of an object. each record in your table can therefore have an object UML unified modeling language ORM object relational mapping
- 17. the tools your editor Sublime Text your design tools Valentina Studio: manage dbs & draw schemas XAMPP, WAMP, etc other stuff frameworks that leverage MVC twitter bootstrap (UI purposes) please try and consider UX and we can't google & stackoverflow
- 18. in closing • it's not all that hard: be willing • other's have done this before: ask around • don't complicate things: know whats feasible
- 19. I did not go as far as you wanted so, what do you want to know?
- 20. oh, these slides ... ? i've posted a link on twitter @amurani
