attention!!!
why human need brain??

 answer is as a storage part and saving information part

So, same as computer its needs brain also as its data storage.

 

 

      thats is: 

1.   RAM is random-access memory

allow stored data to be accessed in any order in a constant time

 2. ROM is read-only memory

computer can read only or retrieve data and programs

3. Flash memory

 

ROM + RAM= can be update to store new information + not lose information when turn off.

others memoery:

• DIMM is dual-in line memory module

• cache (pronounced cash) memory 

• virtual memory

b4 that here i have some tips for u how can computer run faster:

designing alternative system

hye you alls...

today i would like to talk about designing alternative system....

do you know,what is that?????

*system design can be developed to meet the informatin needs

*system designers evaluate each alternative system for feasibility

there is three type of alternative system:

ECONOMIC FEASIBILITY

will new system give you profit?

can we make profit from the system?

investment for system,is that give profit?
ok...
that is the question that we should ask,before we make the system...
cost versus benefits,time for the system to pay for itself.

TECHNICAL FEASIBILITY

before we make the sysytem...

the things that we need to do is...

we need to study thus the system suggested the tecnology already there?

Hardware and software reliability;available and training.

as example:we want to make system which were match with our technology,then the new tecnology that we developed,is that already use here (Malaysia)

 are understand now??

OPERATIONAL FEASIBILITY

will the system work within the organization...?

okey....

this one...

i will explain..

the system that you want to design,is that can be used for the people within the organization?

if it can't be used...better you dont waste your money to design the system...

:)

thanks tq...

CASE (Computer-Aided Software Engineering)

Assalamualaikum
 and
 Good morning alls....
do you know about CASE..?

it stands for Computer-Aided Software Engineering
~~
CASE was originated in the 1970s when computer companies were beginning to borrow ideas from the hardware manufacturing process and apply them to software development (which generally has been viewed as an insufficiently disciplined process).
~~
This tools is used to organize and control the development of software, especially on large, complex projects involving many software components and people...


There are some benefits of using this tools


A product is more likely to meet real-world requirements
~~
Encourages code and design reuse
~~
Reducing costs
~~
 Improving product quality
~~
Quality products tend to improve a corporation's image
~~
Providing a competitive advantage in the marketplace




based on my finding about CASE,
I recommend this tools to you if you want to organize and manage your systems more effective...
this is suitable for you if you are the code writer, designer, tester, planner and manager...
CASE also allow you to share a common view of where a project stands at each stage of development...
CASE tools supported the concepts of structured programming and similar organized development methods...
CASE tools have had to encompass or accommodate visual programming tools and object-oriented programming...
In corporations, a CASE tool may be part of a spectrum of processes designed to ensure quality in what is developed...

Batch vs Real-time processing

hye....

now we are back......

with new information....

Batch vs Real-time processing..... 

Information systems are designed as a combination........

 of real-time and batch processing subsystems.....

Real-time processing is daily work......

 Also called online processing........

 it means that the database is updated as soon as a transaction is received.......

For example........ 

A sales order depletes inventory.......

 a stock sale updates the last close........

 a pledge adds to the fund raising balance........

 Transaction processing keeps business records up-to-date .....

the moment transactions are keyed into or transmitted ...

Batch processing is end of cycle..........

 A month-end report is batch processing as is printing payroll checks.......

There are many jobs that can be more economically processed at the end of a cycle........

 For example........

 the electronic transactions for telephone calls.......

 are stored in the computer until month end........

 when they are matched .....

against the customer tables for updating......

 with all the other telephone transactions at the same time.

that a little bit about it....

that all from us....

see ya....

android ???!?

hye u all...
today i want to share about android...
do u know what is it?


ok..
let me help u..
android is a new 0perating system,that has been use,in handphone...
okey..
for the rest...
 u just keep reading the info that i already find for u...

~this is android diagram~


Android delivers a complete set of software for mobile devices: an operating system, middleware and key mobile applications. The Android Software Development Kit (SDK) is now available.

Open

Android was built from the ground-up to enable developers to create compelling mobile applications that take full advantage of all a handset has to offer.

 It was built to be truly open. For example, an application can call upon any of the phone's core functionality such as making calls, sending text messages, or using the camera, allowing developers to create richer and more cohesive experiences for users. Android is built on the open Linux Kernel. Furthermore, it utilizes a custom virtual machine that was designed to optimize memory and hardware resources in a mobile environment. Android is open source; it can be liberally extended to incorporate new cutting edge technologies as they emerge. The platform will continue to evolve as the developer community works together to build innovative mobile applications.

All applications are created equal

Android does not differentiate between the phone's core applications and third-party applications.

 They can all be built to have equal access to a phone's capabilities providing users with a broad spectrum of applications and services. With devices built on the Android Platform, users are able to fully tailor the phone to their interests.

 They can swap out the phone's homescreen, the style of the dialer, or any of the applications. They can even instruct their phones to use their favorite photo viewing application to handle the viewing of all photos.

Breaking down application boundaries

 Android breaks down the barriers to building new and innovative applications. For example, a developer can combine information from the web with data on an individual's mobile phone -- such as the user's contacts, calendar, or geographic location -- to provide a more relevant user experience. With Android, a developer can build an application that enables users to view the location of their friends and be alerted when they are in the vicinity giving them a chance to connect.

Fast & easy application development

Android provides access to a wide range of useful libraries and tools that can be used to build rich applications. For example, Android enables developers to obtain the location of the device, and allows devices to communicate with one another enabling rich peer-to-peer social applications. In addition, Android includes a full set of tools that have been built from the ground up alongside the platform providing developers with high productivity and deep insight into their applications.

structure of DBMS

hey..

in this post

im here to share with you about 

structure of DBMS

based on this page that i got it..

for your information..

database management system (DBMS)

~~~~~~~

are actually interface between user and database

~~~~~~~

perform various operations on database

but, 

what help DBMS to perform this all various operation?

^^ dont worry..i will tell you..

~~~~~~~

components of DBMS 

help to perform all these requested operations

on the database and 

provide necessary data to the users

DDL Compiler

Data Description Language compiler

it processes schema definitions specified in DDL

DML Compiler and Query optimizer

The DML commands 

such as insert, update, delete, retrieve from the application program

sent 

to the DML compiler 

for compilation 

into object code for database access

then

optimized the best way execute query by query optimizer

and

send to data manager

Data Manager

central software component of DBMS

========================

here we go..

just that for this post!!

see you again..

Best regards,

comparison tool can keep your data..

hye u all...

today i would like share with u,something that maybe help u to safe your databse~

okey!

usually when starting a new project or changing over to a new software program,

 your company's important data will need to be transferred without hassle.

 Database comparison tools make it easy to transfer data or convert a database no matter large or small the database. 

So whether you own a small accounting office, a busy grocery store or factory, it's important to have a safe method of transferring and comparing your data.

Transfer without Error

Data must be transferred or migrated to a new location while remaining in tact.

 You can't risk losing important information such as customer names and phone numbers, or accounting data.

 Your company probably relies heavily on the integrity and accuracy of your database. That's why using data compare tools for a smooth transition is so important.

Reduce Time Frame

You might be overwhelmed with the thought of transferring a large database from one location to another, or even from one type of software to another.

 But thanks to professional tools that compare databases such as Cross-Database Studio, this process can be completed speedily. 

Your database developers can implement the tools and transfer your data in just a few hours or less.

 The data transfer will be quick, but you won't have to worry about loss of data during the process.

How It Works

Database comparison tools have several functions to make your data transfer go smoothly. 

Using these tools, your developer will first generate SQL synchronization or migration scripts. Then he can select the schema objects that need to be migrated. Once selected, migration scripts will need to be created for the selected database objects and saved into an export file. The SQL scripts can be previewed and edited as needed. The next step will be to copy the export file to an offsite location and execute it.

Schema Comparison a Cinch

DB compare tools make schema comparison a cinch once your transfer has been completed. These enable you to compare data to make sure no discrepancies exist. The comparison can be assigned to happen during the night hours when the company is closed or any time that's convenient for your operations. Scheduling capabilities enable you to use the tools whenever it is convenient without actually having someone present at all times.

With database comparison tools such as Cross-Database Studio, your database transfer will not interfere with users as they operate the computers. The package will be compressed to reduce transfer and upload time, the tools can be used again and again, and maintained per product version.

Use database comparison tools

to synchronize a database, accomplish database replication and more. Diff database software, Cross-Database Studio and other tools can be ordered online for your convenience. Start enjoying the freedom and flexibility these tools.

DBMS

Assalammualaikum and good morning everyone...
i hope today is more better than yesterday...=)
today, i want to share about DBMS environment..


do you know what DBMS is..?
DBMS stands for Database Management System
it is a software system that enables users to define, create, maintain, and control access to the database..




there are 5 components of DBMS Environment
which is 

Hardware
can range from a PC to a network of computers
~~
Software
operating system, network software and also the application programs
~~
Data
used by the organization and a description of this data called the schema
~~
Procedures
instructions and rules that should be applied to the design and use of the database and DBMS
~~
People
all users of the database system
system and database administrators, database designers, system analysts and programmers and end users




now, i gonna tell you about...

the functions of DBMS


data storage management
- creates and manages complex structures required for data storage
- stores database in multiple physical data files
~~
data transformation and presentation
- transforms data entered to conform to required data structures
- transforms physically retrieved data to conform to user's logical expectations
~~
security management
creates a security system that enforces user security and data privacy
~~
multiuser access control
uses sophisticated algorithms to ensure concurrent access does not affect integrity
~~
backup and recovery management
provides backup and data recovery to ensure data safety and integrity


and...


the advantages of DBMS


- improved data sharing
- improved data security
- better data integration
- minimized data inconsistency
- improved data accessibility and responsiveness
- improved decision making
- increased end-user productivity
- control of data redundancy
- more information from the same amount of data
- enforcement of standards
- economy of scale
- balance conflicting requirements
- increased productivity
- improved maintenance through data independence
- increased concurrency
- improved backup and recovery services


but...


 it also had some
disadvantages of DBMS
such as..


- complexity
- size
- cost of DBMS
- additional hardware costs
- cost of conversion
- performance
- higher impact of a failure


i get this information for 
Database Principles : Fundamentals of Design, Implementation, and Management
Ninth Edition
