haiz.. term test is on monday le.. and i still haven study yet.. the prob is now the subjects i take i not sure i noe or donno.. haiz.. seems lyk i knew how to do it.. but sometimes i juz don understand anything. argh!! wats wrong with mi.. wth.. its juz term test and im stressed!! im totally stressed!! tis is the first time ever i feel stress for term test!! DSAG im not sure how to write recursion methods!! im confused abt linked list!! OOAD.. logical architecture so tough!! DBSY.. i donno whether im good at it onot.. ER diagram.. participation...cardinality.. the teacher seems lyk stressing mi all the time!! CSAD.. seems lyk veri lil things to study.. but alot of memorising work!!

ARGH!! wat i noe about DSAG.. is write class.. properties.. find output of recursion.. writing loop for linked list..

OOAD.. identify actors, use case, draw use case diagram, use case text, main flow, sub flow, alternating flow.. Draw domain model, identify candidate class using noun phrase approach, differentiate classes and attributes.. whether its relevant or irrelevant.. hmm.. association, generalisation, composition relationships, multiplicity.. 3 layers of logical architecture..

DBSY..primany, foreign, composite key.. ER diagram.. identify entity, attributes, relationships.. each relationship represent a foreign key.. each entity is a table.. the shapes tt represent relationships, weak relationship, attributes, derived attributes, multivalued attributes, entity, weak entity, cardinality, participation.. 1:1 relation the participation determines where the foreign key should be placed.. if not.. can be placed in any entity.. weak entity.. oways have total particiption with its owner, the unique attribute + the primary key of the owner forms a composite primary of the table. 1:n.. the foreign is oways on the N-side.. m:n forms a new entity itself.. multivalued attributes.. the primary key of the table + the mutivalued attribute form a table itself.. n-ary.. relation forms an entity itself with the primary key of the entities involved that make the primary of the relation.. converting er diagram to schema..

CSAD.. i donno haven study.. is PBL.. learn it urself..

ok.. thats basically i think wat i noe and donno.. donno.. got miss ou anything bah.. can i pass well with the things i noe now? haiz.. sianz.. no mood to study.. i last thing.. i hate theory qns!!
