Analysis --- In order to provide functions, what core mechanism should be in the system. Design---In order to provide performance, how to realize the core mechanism of the system with selected technology
Shao Xiao (20***28) 14:09:43
Teacher I think this sentence is not right
Shao Xiao (20***28) ) 14:10:48
Design---In order to achieve function and satisfy performance, how to realize the core mechanism of the system with selected technology
Shao Xiao (20***28) 14:11:50
I think the purpose of design is not performance
Shao school (20***28) 14:11:58
function is the main performance is secondary.
Shao school (20***28) 14:12:27
I was confused when I first read this sentence.
Pan Jiayu (3504847) 14:14:12
@绍校 That's right. The function (core domain knowledge) is solved in the analysis workflow.
Shao Xiao (20***28) 14:14:38
Yes, analyze and find out the function. But design is not designed for performance.
Shao school (20***28) 14:15:05
Is the purpose of design for performance? Obviously not
dust language <xnon***[email protected]> 14:15:11
Shao school is very serious
analysis-function
design-performance
dust language <xnon***[email protected]> 14 :16:19
The focus of the design stage should shift from function to performance
Shao Xiao (20***28) 14:16:39
The teacher said, code is design. Not writing code for performance. Write code in order to satisfy the function. It's just that the code written at this time, there are high-performance and low-performance
Chenyu <xnon***[email protected]> 14:16:48 The
focus is different, the focus is different.
The dust language <xnon***[email protected]> 14:17:14
code contains all the results of the previous stage.
Chen Yu <xnon***[email protected]> 14:17:20 and
finally implemented
Shao Xiao (20***28) 14:17:42
Yes. That is the purpose of this sentence. It is for performance.
Shao school (20***28) 14:17:46
I think it is a partial overview .
Shao school (20***28) 14:18:30
analysis-refine function design-realize function
dust language<xnon ***[email protected]> 14:19: 10
layers of decomposition The
dust language <xnon***[email protected]> 14:19:23
The focus of each layer is different.
Shao Xiao (20***28) 14:20:29 If you
design, you should use design patterns to deal with real changes. And using design patterns, can it definitely improve performance? In most cases , Pan Jiayu (3504847) 14:20:29 reduces performance. A final source code (the so-called design) realizes the analysis and conception mechanism, indirectly realizes the system requirements, and indirectly improves the value of the organization. Indirectly increased the total welfare of mankind. However, the same analysis, why you choose this design, the focus of thinking is performance. Pan Jiayu (3504847) 14:21:10
@绍校Analysis-Refining Function Design-Realizing Function-
I'm
not right, then review Pan Jiayu (3504847) 14:21:39 Think clearly about what workflow concept "function" belongs to
Shao school (20***28) 14 :21:51
Analysis---In order to provide functions, what kind of core mechanism should be in the system. Design---In order to provide performance, how to realize the core mechanism of the system with selected technology
Shao school (20***28) 14:22:04
I mean to refine the function and realize the function is the purpose
Shao school (20***28) ) 14:22:08
instead of the process
Pan Jiayu (3504847) 14:22:54
and review again Chenyu
<xnon***[email protected]> 14:26:21
The focus point of each layer is different, so eyebrows and beards are not allowed Grabbed.
In the design stage, if the analysis is not in place, you should return to the previous level and make adjustments there.
This discussion is pretty good:)
For someone like me who doesn't read carefully.
Shao Xiao (20***28) 14:29:48
"Design---In order to provide performance, how to implement the core mechanism of the system with selected technology". What does the term "selected technology implementation" mean? The type of language selected, the platform of the system? Can there be good performance with c++? Is it worse with other performance?
Shao school (20***28) 14:30:09 Does the
selected technology mean to select the language and deployment environment?
Shao school (20***28) 14:30:38 The
design process is more than just selecting the technology , And also need to use technology to achieve.
Shao school (20***28) 14:30:46
I think the realization is the main thing
Shao Xiao (20***28) 14:31:18
Design is a process of realization
Chenyu <xnon***[email protected]> 14:31:38
Analysis - Mapping
--Design (framework, database, program code,..., deployment environment) Chenyu <xnon***[email protected]> 14:32:36
Well
Shao school (20***28) 14:32: 41
According to Qian Ge, design is to directly select the implementation method.
Shao school (20***28) 14:32:46
has nothing to do with writing code
Shao school (20***28) 14:32:58
choose a set of program performance is better
Shao school (20***28) 14: 33:03 Set
b is the second, choose a
Shao school (20***28) 14:34:03
But most of the work lies in the core domain to code mapping
Shao school (20***28) 14:34:28
The focus is not the same
Shao school (20***28) 14:35:19
The focus of the teacher is selected again.
Shao Xiao (20***28) 14:35:29
My focus is on the realization process
Pan Jiayu (3504847) 14:37:53
@绍校 The new version has been modified, you can see the web version of
Shao Xiao (20** *28) 14:38:06
Okay. I will look again, thank you teacher Pan
Pan Jiayu (3504847) 14:38:10 Chen Yu <xnon***[email protected]> 14:40:19 Analysis <---forward and inverse---> design <---forward and inverse---> code , Database,... Pan Jiayu (3504847) 14:42:15 @尘语code, database...is the design Chenyu<xnon***[email protected]> 14:42:25 ah Shao school (20** *28) 14:42:32 Yes, I understand what the teacher means. The analysis is to meet the functional design is to meet the non-functional requirements. But what I mean is that one of the important purposes of design is to achieve functionality. It's not just non-functional. Function is more important. Isn’t the analyzed artifacts to better enable the design to achieve functions? Because the analysis phase has not yet implemented the function. Shao Xiao (20***28) 14:43:37 in turn think about where the function is realized. Where is the mapping code mapped. Isn't it the realization of the analysis artifact? Shao Xiao (20***28) 14:44:25 According to the teacher's modeling workflow, the result of the analysis is the precondition of the design. Shao Xiao (20***28) 14:44:30 analysis did not realize the function Shao Xiao (20***28) 14:44:57 So why did not say that the function was realized in the design stage, and it went to the dust with performance Language <xnon***[email protected]> 14:45:06 is implemented in a virtual operating environment Chenyu <xnon***[email protected]> 14:45:22 For example, in the brain
Shao Xiao (20***28) 14:45:44 The
ultimate goal of software development is to obtain a set of source code
Chenyu <xnon***[email protected]> 14:45:45
I will go out to
Chenyu<xnon* **[email protected]> 14:46:09
Well, you have to get it in your head first.
Shao Xiao (20***28) 14:46:21
code is the result of the implementation.
Chen Yu <xnon***[email protected]> 14:47:29
We are not users,
we are analysts and designers.
Check whether the system can be realized by yourself, you have to do it.
Direct code?
Chenyu <xnon***[email protected]> 14:47:38 Cross the
river by touching the stones?
Shao Xiao (20***28) 14:48:21
So the design should contain two purposes in order to achieve functional and non-functional requirements and design constraints
Shao Xiao (20***28) 14:48:34
the knowledge part you said
Shao school (20***28) 14:48:37
is just
dust language <xnon***[email protected]> 14:48:37
book review.
Teacher's class.
Shao school (20***28) 14:48:55
Okay, let's discuss it here. Thank you
Chen Yu <xnon***[email protected]> 14:49:02
Discussion and discussion are very good.
Pan Jiayu (3504847) 16:28:00
@绍校 A few of my answers should be more clear, take a closer look at my words.
