ACCESS,need little Basic code.For the common application at desk system,I think,ACCESS is a good one.
It will help us do most of the works,includes interface,sql statement generating...

A girl should be a gentlewoman more
I think,a girl should appear a gentle face and with a tough-minded heart.This is my education principle to my two-years' daughter.
I found there are some different opinions about education for daughter between her mother and I,this need time to communicate,and,I think,these communication should choose the time that daughter is absent.Maybe,there will be a violent argument between us:)
make a quick review of Advanced Math
In order to learn Probability,I must make a quick review of Advanced Math.I found if I learn it carefully,it will take me a lot of time, and,to understand something in it at my first review is a bit difficult.So,the iteration method should be imported in my learning it.
After two weeks' tuning,I will start a new learning phase.
Finished PRE-TEST UNIT 2 of NCE
The same mistake always happens again and again for me in learning english.
1.Present tense can express an action always happens,but express an action always happened in the past time should use Past tense except in the direct speech which person said that in the past time;
2.The position of adverb to express frequency:
1)He always does this.
2)He must always does this.
warning,your learning english have stopped a week!
Learning need persistence,can't break a long time,or the time before will waste.So,I must learn it continuely next week!
ArgoUML says:"...ran out of memory..."
This is a strange thing,although I have resolved it,but I haven't understood it yet.About a week ago,when I run ArgoUML,it said "ran out of memory,rerun argouml with heap size increased." regularly.Then I did a lot of things:scan viruses,update jdk to 1.5,reinstall OS...,but it is no effection!
Later,I searched a mail at argouml.tigris.org,resolved this matter by adding Non-Standard Options with "java" command.it is:java -Xmx192m -Xms192m -Xss8m -jar argouml.jar.
There are still two doubts in my mind:
1.Why did I run the argouml normally before a week ago but can't run it normally later?
2.Does argouml on earth need so large memory to run it?I have a lot of doubts!
the usage of 'except'
If "except" is at beginning of the sentence,"except for" is used,it is equal to "apart from".
i.e.
Except for/Apart from this thing,everything else is good.
All students go to cinema except John.
"must" and "may,might"
He looks very sadly,he must have gotten a bad score at last test.(express the deduction from known facts);
He may have gotten a bad score at last test.(express the possibility or conjecture)
If it is a logical reasoning then the word-'must' is used,or if it is a subjective guess then the word-'may' or 'might' is used.'May' express a stronger possibility than 'might'.
fail again
These days,I tried to model Filesharing Module with activity diagram mainly.But,activity diagram cann't express the interaction between objects.
This time,I tried to put analysis and design model into one file.I think,the fruit of analysis model can be used to yield other design scheme.But,my experiment has been proven that it fail again.
If an activity diagram can't express interaction?
If "actionstate A" will call "actionstate A1",and "actionstate A1" will call "actionstate A11",then there is an "actionstate B" after "actionstate A"...
Can the activity diagram express these interaction?
A sad truth,there isn't sequence diagram in ArgoUML.If the activity diagram can't express the interaction between Objects,I will use collaboration diagram to express these model in my design phase of Filesharing module.
