Thanks guys.

I read somewhere that the rules of normalisation are not to be followed in absolutely all cases. Is this one of those cases? I really don't know.

I understand that in samm's solution, there are three columns in the course table that are redundant, score1, score2, score3 and this is probably the reason sbucareer normalised the the course table and used a foreign key instead. The problem is that I do not understand how the normalisation and consequent usage of a foreign key would handle the three required scores e.g. midsemester, assignments and final exam as indicated in samm's solution. I understand it is good practice to avoid repitition of columns but how would the normalised version actually work in handling the three scores.

Could anyone please explain this to me? Thanks a bunch.

@sbucareer
Thanks for your contribution. It is highly appreciated.

@samm
Thanks again.

I understand basic database design concepts (primary keys, foreign keys, etc.) and I'm sure that has helped me in understanding your ideas and putting them into my skull and they seem to be a really good way out of my problem. Thanks a lot. I'll work on this and see how it goes.

I respect,

Samm, thanks a lot. I will go through your idea.

More design ideas are welcome by any other person willing to help,

Thanks a lot guys.

I would really appreciate any help from you, kolinz.

As to why I would suggest Python. Python is a powerful object-oriented programming language with really simple syntax. It therefore goes a long way in illustrating programming concepts which run through most languages in an easy to understand way. Python is sufficiently powerful and useful on its own for various sorts of applications but if one decides to learn any other programming language after thoroughly understanding Python syntax and concepts, the person in question would find the learning process easier due to his previous knowledge of Python. That has been my experience.

I've been wondering how to come up with a relational database design for a student grading and result collation system. I am not particularly good at database design and I would need some expert help.

What I want to know in essence is how to design a relational database to handle student results and GPA calculation for a typical university (100L - 400L/500L). The data would be stored in such a way that a particular student would have his records stored from 100L - 400L during his stay in the university.

Please, my explanation may not be exhaustive enough but what I am essentially trying to know is how a database is designed to handle student results and GPA in a university.

Database design happens to be my bane in computer programming and I need serious help please!!! Thanks a bunch.

I'd say anyone should start learning programming by learning Python.

I don't know about Styl Plus, but Peter can hardly do without Paul.

Just be careful in the choices you make on how to approach this, lady.

Quite unfortunate. Maybe she should explain things to her boyfriend in full.

As long as you are not Joseph, it's just a dream.

tough question, I'll just assume never saw it,

, zooming off,

The first time I heard one of Durella's songs, I actually thought it was D'Banj.

The guy is really good, no doubt. The first time I heard Ololufe, I did not know it was a Nigerian song until I heard the chorus. His voice is really good and I hope he plays his cards right 'coz I thiink he deserves to be one of the very best in the Nigerian music industry.

one of my colleagues in office uses flex. its very cool. i have seen some of the projects he and other flex fans have design. they are very cool. it works with any lang such as php, delphi etc nto just actionscript

Right now I am studying understanding the Adobe Flex application in order to compiling the SWF build using FlashDevelop 3. I am so excited!

Yeah,I have heard applications created with Flex are pretty cool. And I have heard it is pretty exciting. I'm planning to get familiar with the it too. Just needed some encouragement. Thanks guys.

Yeah, but we get the point though.

Adooooooooooooooooooobbbbbbbbbbeeeeeeeeee Dreeeeeeeeeaaaaaaaaaaammmmmweeeeeeeeeeaaaaaaveeeeeeeeeeeerrrr

Sorry about my fantacism

Let's see the logic. Personally, I would love to see it. It would go a long way in getting you help. Anyone who is bored by it, probably is not willing to or cannot help.

I'm surprised nobody is talking about time travel, probably because it is merely a far-fetched dream.

Actually, I strongly believe humans would get to a stage where we would be able to manipulate the time-space continuum. Although, this may have disastrous consequences, I believe this would a wonderful discovery that would change the world as we know it.

Someone recently introduced (or rather told me about) me to Adobe Flex. I would like to know if there are any experienced users of Adobe Flex in the nairaland community to educate me on its pros and cons and its role in software development.

I know it is flash-based and its operational language if ActionScript.

Just how cool is it?

Linux and other Unix derivatives are not usually open to a lot of threats, that's just why I love it in the first place.

Laptop is slow - Most likely virus problems, get a good antivirus and carry out a full system scan.
Battery life is not more than ten minutes - Battery is used out, get a new battery.

I think it is that simple.

Is it actually true that hibernating a laptop diminishes your overall battery life over time? That is, does it actually destroy your battery?

banky did not start wit wbutte metta. he started with songs like ay mami, capable, majekodunmi, my regret, work you out, then ebute metta, the fact that ebute was a gift and curse to him does not say dude is not talented, so if u don't understand publicity, sshut the fuc kup. because banky got what it takes than anyone else. banky is more appealig than wande coal. even though wande has agreat voice!

Absolutely true talk, pal

Cassie is cute, Rihanna is trying to be cute.

She's okay, not spectacular, but okay

Some tracks in the Hot Candy Album are cool shaa e.g. 4 Minutes feat. Timbaland.
