CS and CE Examination!

Haha....last day for the foundations in Arts for computing studies and computing essentials!! Any tips? I have some, so go and post the tips in there...woohoo! ^^

Computing Studies? Wow.....examination is coming eh? Tips...haha, well, I wish all the best of you in da exams! ^^

wei wei wei .... got tips dont wan to post up

everybody will kill u de...hehehe

Hahaha.....computing studies? Hmm....did school of music have to take this subject too? hmm......haha, anyway good luck to you all! ^^

haha...we need tips....come on kendrick to be our saviour!!!!

Haha.......kendrick as the saviour? ^^ you were cute lar J-kid.....haha, good luck in da exams ! and Computing studies too!

Haha....ok ok, now i will be giving out some tips regarding CS....take it as a Study Guide...lol
Section A:

---- 4 number System Questions
(Can say like convertion from bases to other bases...lol)

---- 1 machine language Questions
(Hmm.....remember the RXY thingy? and C000 as system halt? That is the one ...lol)

---- 1 Flowchart Question
(OMG!! here it comes....drawing of da flowchart)

Section B

Okay.....divided in to three types....MCQ, True and False and Short answers(Fill in da blanks)

All from chapters 11,12, 13 and 14 (70% ooo...)

Okay....now some guide...lol

In da flowchart question, the question will be sort of like that--> Draw a flowchart that when you Input an integer number ,it will auto calculate the factorial number and display the factorial numbers out.

Next :Chapter 11, read these points then you can pass lol..^^

Competencies :

1. Data organization

• characters, fields, records, files
  

2. Batch and real-time processing
3. Master files and transaction files
4. File organization sequential, direct, index sequential
5. Advantages of a database
6. DBMS elements Competencies
7. DBMS organization

• hierarchical
  
• network
  
• relational
  
• object-oriented
  

8. Individual, company, distributed, and proprietary databases characteristics
9. Productivity and security
(Note:DBMS stands for Database management Systems)

Overview:

1. Finding the information
   
2. Scalable data files and databases
   
3. Sophisticated database capability
   
4. Internet access expands data access
   
5. Data Files
   
6. Understanding how data files work
   
7. understanding data organization
   
8. key fields
   
9. batch versus real-time processing
   
10. master versus transaction files
    
11. file organization.
    

Data Organization:

• Character
  
• Field
  
• Record
  
• File
  
• Database
  
• field
  

Data Organization(2):

• Character
  
• Field
  
• Record
  
• File
  
• Database
  
• Key Field
  
• A unique identifier for each record
  
• Contains unique information
  

File Organization:
Direct file organization:

1. Records stored at a specific address
   
2. Hashing converts the key field value into a corresponding address
   
3. Must be done on a disk
   
4. Record can be quickly accessed by going directly to its address
   
5. Higher cost than sequential
   
6. Direct File Organization
   

File Organization:

1. Index sequential file organization
   
2. Compromise between direct and sequential
   
3. Records stored sequentially
   
4. Index created that records address
   
5. Index Sequential File Organization
   
6. Database
   
7. Databases integrate data
   
8. DBMSs create, modify and access databases
   
9. Traditional file management systems inefficient
   

Result of the use of Database:

• data redundancy
  
• lack of data integrity
  
• Database Management
  

Enable users to:

• create, modify and gain access
  

• Data dictionary
  
• Data structure description
  
• Defines field names, types and sizes
  

Need for Databases (Why need it?)

1. Sharing of information
   
2. Security
   
3. Reduced data redundancy
   
4. Data integrity
   
5. Database Management
   

DBMS organizations (Types)

• hierarchical
  
• network
  
• relational
  
• object-oriented.
  
• Query language
  
• Method of access
  
• Easy-to-use language
  
• Structure Query Language (SQL)
  

Hierarchical Database:

• Structured in nodes
  
• Viewed as branches
  
• Each item is subordinate to parent node
  
• Only one parent per node
  
• Subordinate is the child node to the parent
  

Hierarchical Database:

If parent node is deleted, all the child nodes deleted
New parent node must be created before adding new child node
Limited by rigid structure
No direct relationships between child nodes
Hierarchical Database
Network Database
Hierarchical node arrangement
Child nodes may have a many-to-many relationship
The interconnected design allowsfor access via multiple pathways:

1. Network Database
   
2. Relational Database
   
3. No pre-determined access paths
   
4. Data stored in a table or relation
   
5. Tables may be linked via a key field
   
6. Easy to add, delete and modify the data and table structures
   

Relational Database :
Access Database Window

Continue next post....lol

Continued....

Okay...
Chapter 12, 13 and 14...

Chapter 12 will be System analysis and Design,

so , read the 6 phases of sytems life cycle.
----and the elaborate the 6 terms (Read it throughly)
Dun forget designing alternative systems on Economic Feasibility, Technical Feasibility and Operational Feasibility .
Also not to forget system implemention - Direct approach, parallel approach, Pilot approach, ans phased approach.
Maintainence on AUDIT....

Examples :
The ____________approach conversion type simply involves abandoning the old system and using the new.
A. Direct B. Pilot C.Phased D. Parallel

Chapter 13, programming and languages

Note: Remember the 6 steps of software developement!!
Elaborate each of the steps, not to forget PSEUDOCODE,
FLOWCHARTS, LOGIC STRUCTURES, SEQUENCE ,LOOP and SELECTION structures,
SYNTAX and LOGICAL errors, DESK CHECKING, DOCUMENTATION,CASE TOOLS,
OBJECT-ORIENTED SOFTWARE DEVELOPEMENT (OOP), and the 5 generations of
programming languages....^^

The final one on Information Systems

• Organizational Flow
  
• Management levels
  
• Information flow
  
• Computer based Information Systems
  
• Transaction Processing Systems (DPS-Data Processing Systems)
  

Hmm....I
want to say that I dun really sure if our Lecturer will came out 100%
in the guide given above but this guide may help us gain marks...haha.
anyway, i want to say good luck to everybody in Computing Syudies Exam!
Gambateh! ^^

Whats the different with reading the whole chapter ? XP

Yalar....hahaha...its only a guide....its is a guide for you to read through the book...wakakaka, its not TIPS, its study guide...lol

Its far more different...
Just like point form...
Not recomended if you use to study the chapter for the 1st time...
Better read trough the notes first then use this to rivise...

SCREWWWWWWWWWWWWWWWWWWWWWWWWWWed

ya...wish you all the best in next semester!^^

.....NaMoOlyTuoFo....God bless you.....!:tongue:

when is the final exam for UCSI students? hope u guys PASS WIF FlYING COLOURS in the exam..

GAMBATEH

What I can tell is that, programming is way more harder to study.... So have to study and learn that many kinda things like that is not an easy thing to do.
If for me, I'll also be dying for learning all of these...

Haha! Kendrick, talking about the pseudocodes.... I think most of us didn't like it at all during the time at senior3 last year...
All of us juz got mcc when teacher Vivian was teaching us... and we usually, especially, uncle yap and jiun ming always got many questions to ask and made her confused... and the gals are all poped up with question marks and only Ah yu knows what the teacher was saying...haha!
I do really miz the time....
Btw, I can see that your computing studies is more in to the database and programming topic, rite? Cuz' I saw you guys have to study for pseudocodes, the program structure design and the database hierarchy and database management system kinda things like that....
For me, I'm juz started to study about the basic of theses topics only, not into complex level. But I believe in next sem, I'll have to study something like that, soon.... So I think I be dying with it....
Anyway, for Kendrick and those of you who study this cource or Kendrick's classmate, hope you guys can pass or pass in higher gred in you exam! So gambateh, and good luck to you all! May God bless you guys!

Thank you wah^2, haha, your wish is really meaningfull to us Thank you very much and good luck to you too! Gambateh we both!!

Wow...all here wishing...okay, i am here to support all of you who are taking computing studies. Good luck!

Thank you!!hehe, support!! Support!! Over!
