murinmalengko 0 Report post Posted February 21, 2007 ermm..assalammualaikum..saya dah letak soalan ini dalam pengkalan data...saya rase soalan saya sebenarmyer lebih berkisar kepada penggunaan aspmaker ...mintak tlg pada mereka2 yg pandai.. saya tgh berusaha buat sistem online utk tuntutan elaun perjalanan ..masalahnye skrg..saya sangkut kat database..saya menggunakan aspmaker dan msAccess utk buat sistem ni...relationship antara table2 membuatkan saya semakin pening dgn sistem ni...mm...bendenye rasenye simple jer..tp sy still x tau mcmner dan apa yg sy tgh lakukan sbnrnyer...dlm sistem ni..let's say,sorang pensyarah...pergi kursus kat sabah sana..dia melibatkan satu tuntutan,byk perjalanan dan kemungkinan byk tol...die bergerak dari rumah naik kereta sendiri (tuntutan perbatuan) then kena g KLIA..katekan die kena byr tol kat sg besi...naik kpl terbang(waran,x pyh tuntut)..naik teksi kat sana(tuntutan teksi)..then stay kat hotel(yg ini melibatkan mkn , lojing,etc sumer)..lepas tu balik semenanjung semula..naik kereta...kene tol...sampai rumah...view sistem tu lebih kurang camni arr..user (user dalam sistem)tuntutan ( bole buat byk tuntutan,tp satu je dlm satu bulan)perjalanan(tol) (dalam satu tuntutan tu ade byk byk perjalanan and dlm perjalanan tu ade tol yg juga mungkin bole byk)adeii ...pening2 ...cmne nak relatekan semua rekod2 ni supaya saya bole recall semula utk history dlm sistem tu...that's mean,pensyarah tu bole buat tuntutan baru utk bulan seterusnya,tp still bole tgok dienyer tuntutan yg lama2??dlm aspmaker tu ,mmg die generate sumer table yg kite dah relatekan tu...tp masalahnye,katekan kalo kite add new perjalanan, mmg die masuk dlm database...tp user bile nak view data dlm list...user bole tgok sumer perjalanan user2 lain...sy tatau nak restrict kan die...ni kene pakai accesslevel dlm aspmaker tu ker?nak setup mcmner?bile buat tuntutan tol pon same..sy menggunakan tol id sbg PK(autonumber) ,bile saya relatedkan dgn id_tuntutan atau id_perjalanan..user kena input id tersebut...dimana mereka sudah semestinye x tahu apa2...saya guna alternative nokadpengenalan utk mudahkan input data...tp masalahnya kalo camtu..Id_tol tu x update dalam table perjalanan..bile dalam perjalanan x update...table tuntutan pon x update...and so on..waaa..pening2... blink.giftlg ek pada sape2 yg pandai...trimas Quote Share this post Link to post Share on other sites

ijurq 0 Report post Posted February 21, 2007 (edited) database ko ni tak cukup normal..ce buat normalization....kalau nak buat sistem...kenal pasti la sape actor, ape role masing2....and sbb ko nye ni web based..ce ko buat satu activity flow ke..and then ko kena pasti ape data yg terlibat...baru nmpk ape jenis table ko nak pakai...ni pendapat aku la..

Unless memang dah last minute mm..actually mmg dah masuk fasa last minute dah ni...hehe...about one and half month to go and baper hari je lagi utk 1st review...xpe..nikmat coding still akan dirasai sbb sistem ni more pada application....waa...ni yg mentel ni..saya pilih utk guna aspmaker sbb senang nak control security die..lagipun dalam sistem saya ni ada 3 pihak...pemohon..pengesah..and admin...so view dorang lain2...rasenye kalo pakai aspmaker ni kat admin and pengesah tu dah xde masalah...generate then edit view je...tp kat pemohon ni yg susah banyak...camne tu camne ni....

ijurq 0 Report post Posted February 21, 2007 Database Normalization When creating a database, it is often useful to learn from the mistakes of others. Within the Relational Database Model, a set of rules has been established to aid in the design of tables that are meant to be connected through relationships. This set of rules is known as Normalization. In this Tutorial we will address the first of five normal forms, and the ways in which normalizing your database will help prevent problems as you add to it. The concept of database normalization is not unique to any particular Relational Database Management System. It can be applied to any of several implications of relational databases including Microsoft Access, dBase, Oracle, etc. The benefits of Normalizing your database include:• Avoiding repetitive entries • Reducing required storage space • Preventing the need to restructure existing tables to accommodate new data. • Increased speed and flexibility of queries, sorts, and summaries.There are five normal forms in all, each progressively building on its predecessor. In order to reach peak efficiency, it is recommended that relational databases be normalized through at least the third normal form. In order to normalize a database, each table should have a primary key field that uniquely identifies each record in that table. A primary key can consist of a single field (an ID Number field for instance) or a combination of two or more fields that together make a unique key (called a multiple field primary key).

murinmalengko 0 Report post Posted February 21, 2007 Database Normalizationsaya dah try wat normalization pakai analyzer...rasenye saya dah faham sket...tapi saya x sure ape yg saya buat tu betul ke salah sbb hasilnye hanya nampak kat query...saya nak tanye...apa yg terjadi kalo sebenarnye database kite r/ship die MANY-TO-MANY???kite kena create bridge (junction table) jgk ek?saya bayangkan table saya ikut situasi ni...1 person in Employee table can take several courses,and the same course in the Courses table can be taken by several employees1 person in pemohon (Data Peribadi table) table can make several tuntutan,in the same tuntutan (Data Tuntutan Table) bole menuntut claims untuk several perjalanan (Data Perjalanan table) ,in the same Perjalanan can include several bayaran tol (Tol table) ke saya boleh teruskan je dgn database ni...pakai table2 yg saya dah linkkan tu?
