INFOSYS National J2EE Fast Track Batch 8 Week 2

30/01/2013 (Wednesday)

Starting to learn:

- RDBMS.
- ER modeling.
- ERD case studies.
- Transforming ER model to relational schema.
- Functional dependencies.

Meh Anna terang sikit sebanyak apa yang Anna belajar hari ni...

* RDBMS stand for Relational Datbase Management System. RDBMS ini merupakan satu software yang digunakan untuk menyimpan data menggunakan SQL (Structured Query Language). Data-data disimpan dalam bentuk table dan mempunyai hubungan antara table-table tersebut atau dalam erti kata lain database management system (DBMS) that stores data in the form of related tables. Relational databases are powerful because they require few assumptions about how data is related or how it will be extracted from the database. As a result, the same database can be viewed in many different ways.

* ER Modeling stand for Entity Relationship Modeling. ER Modeling is data model for describing a database in an abstract way. ER Modeling ni mengandungi entity, attribute dan hubungan.


* ERD case study ni pulak, kita akan diberi satu case study and then solve dalam bentuk diagram.


*  Transforming ER model to relational schema example:



Student(ssn, last, first, streetaddress, city, state, country, zip)
Course(dept, number, title, description, credits)
Section(crn, days, time, room)
Faculty(ssn, last, first, title, dept, office, phone)
