Thanks so much Madam Badariah coz teach me and guide me….

Ahmad Marzuki 

Puan Badariah teached me chapter 11

what is Software Rejuvenation

Redocumentation:  static analysis adds more information
Restructuring:  transform to improve code structure
Reverse engineering:  recreate design and specification information from the code
Reengineering:  reverse engineer and then make changes to specification and design to complete the logical model;  then generate new system from revised specification and design

this is the last attendance  day ……

lecturer explain about the meaning of system evolution means enhancement of functionality system,correct maintenance and correcting error

lagacy system means use system for old people use such as banking system.

It seemed there is hope to get marks in assignment 2 project from the meeting to Madam Badariah  this week.To all group member strive the best in assignment 1 & assignment 3 project.

member group cooperation is so significant to get hingest mark…

i hope madam can reconsider our assignment 2 project .

Stage of Testing

Regression testing. Where this version of the software is tested with the automated test harnesses used with previous versions to ensure that the required features of the previous version are still working in the new version.
Recovery testing. Where the software is deliberately interrupted in a number of ways, for example taking its hard disc off line or even turning the computer off, to ensure that the appropriate techniques for restoring any lost data will function.
Security testing. Where unauthorised attempts to operate the software, or parts of it, are attempted. It might also include attempts to obtain access the data, or harm the software installation or even the system software. As with all types of security it is recognised that someone sufficiently determined will be able to obtain unauthorised access and the best that can be achieved is to make this process as difficult as possible.
Stress testing. Where abnormal demands are made upon the software by increasing the rate at which it is asked to accept data, or the rate at which it is asked to produce information. More complex tests may attempt to create very large data sets or cause the software to make excessive demands on the operating system.
Performance testing. Where the performance requirements, if any, are checked. These may include the size of the software when installed, the amount of main memory and/ or secondary storage it requires and the demands made of the operating system when running within normal limits or the response time.
Usability testing. The process of usability measurement was introduced in the previous chapter. Even if usability prototypes have been tested whilst the application was constructed, a validation test of the finished product will always be required.
Alpha and beta testing. This is where the software is released to the actual end users. An initial release, the alpha release, might be made to selected users who would be expected to report bugs and other detailed observations back to the production team. Once the application has passed through the alpha phase a beta release, possibly incorporating changes necessitated by the alpha phase, can be made to a larger more representative set users, before the final release is made to all users.

i hope all can attend to discuss about assignment 3.
