It seems to me your bank is just using the wrong approach here. Why not
add a second system that links the data from the old system with data
from a new system? Compare it to building houses. If you have one house
with 4 floors, you can often add one or two more floors without having
to bread down the old building. Sometimes you will need to add some
reinforcements within the current building and perhaps adjust the
current roof but hey, it is possible. And if you really can't put
anything on top of it, put something next to it since that is always a
better solution than tearing down an existing solution and then hope
you'll get something back that is as reliable as the old one...
Replacing a well-proven system by an unproven new one is always a big risk. One flaw could become quite expensive...

RE: The redneck knows about us...
I think the problem with Oracle is that they don't know which platform to support so they use Java to create a GUI that's supposed to be supported by all platforms. Of course not even Java is truly platform-independant but okay. They've created something, it's crap but hey, it also works!
Oracle is primarely interested in optimizing the database and they don't care that users need to set thousands of tweak options to get it running in the most optimal way. Other databases have all kinds of tools and wizards that will just estimate the best settings for their database but this is something Oracle just can't think about. They're in the business of storing data so who cares about user-friendly installations?
Besides, the revenue from all those people who need to be certified Oracle geeks is quite high as long as the product is popular. Since Oracle is a major player on the Unix market, where most geeks dislike user-friendly tools in the first place, I don't think they will change their ways any moment soon...
Of course you can consider SQL Server a better product because it's more user-friendly and every moron can use it. But SQL Server only runs on the Windows platform and is considered hopelessly insecure because Windows needs to be patched about twice per week or so, to fix a bunch of vulnerabilities and buffer overflows. And then I haven't even started about all those computer virusses on the Windows platform. No, from a security point of view, Oracle is better because it requires professionals to set it up and it can be installed ion an Unix platform that is less likely to be infected with virusses or cracked by hackers.
At least, that's what most people think anyway...
Of course SQL server is also insecure because most people who install it just use default settings and thus end with mostly default usernames and passwords. And it might leave too many ways open to access the server too. Dumb users will create very vulnerable SQL Server installations but they fill fail at installing Oracle properly...
And as long as there's no serious competition on the Unix platform, Oracle will probably stay in business too. Of course, DB2 is a good alternative, yet with similar weaknesses. Too complex for the average user. InterBase is a lot easier to install and more user-friendly but it's not really capable of handling the huge pressure that many larger companies will have to deal with.
For personal use, MySQL or Access are much better alternatives anyway. But all those "minor" databases fail if they have to deal with the amount of data that average Oracle/SQL Server/DB2 databases have to deal with. These are the big players and as long as they don't have any serious competition, they will just do whatever they like... -

Darn. I should not have posted that. Now my topic is on the second place... [:S]
Btw. It would be nice if those RSS feeds would also bring me to that
last post. Especially useful for those topics that span multiple pages.
And perhaps you should offer the RSS feeds in two flavours. One sorted
by date of original post, which brings you to the first post. And one
sorted by date of last reply, which brings you to the last reply... -
RE: Rss .. Fixed?
I have to seriously disappoint you. I just noticed that this new RSS
feed, which you apparantly use for this forum, is messing things up a
bit in my FireFox/Sage environment. When I click on the feed, all posts
listed are in bold font, suggesting that these are new items.
Unfortunately, they are not but some topics might still be new.
Another problem is when I click on one of those links, I go to the page
but apparantly I'm not logged in. However, if I go to the RSS feed of
another forum and click there on a link, I am logged in again. (And no,
I don't have to log in again.) Apparantly those links are telling the
system that I am not logged in. But I am logged in! Weird. -
RE: Idea for new section
Actually, seals don't make that much sounds to begin with. Young seals
make some crying sounds when abandoned and hungry but most adults are
silent. I think you're confused with sealions again...
You do know the difference between sealions and seals, do you? A
sealion can stand on his front flippers and even use them to manipulate
objects. They can also bend theit back flippers below their body to sit
on them. Seals have shorter front flippers and their back flippers are
a bit stiff and directed to the back. They can't do much with them,
except in the water. In the water, seals are better swimmers than
sealions because their flippers are more streamlined and more stable.
Seals have a better stamina too.
Another difference is the amount of fat layers that they have. Sealions
tend to have less fat layers than seals. Not suprising, since sealions
live in more tropical and warmer areas while seals are found in the
most coldest places in this world. Which is why the flippers of seals
are also smaller because smaller extremities help to keep body heat
inside.
And if a seal does make a sound, it's more like a bark of a small dog
with the flu than the sound of a sealion. Or a growl if you're in their
way... And did I say already that they have a very mean bite? If a seal
bites you, you'll have to get a tetanus-shot because the bite will be
infectious. Seals are carnivores and wild seals can have pieces of
rotten fish between their teeth, which causes their bites to be
slightly poisonous... -
RE: The redneck knows about us...
<font size="3">I like his reply. He has an advertisement to a book at the bottom for a book called "</font><font color="#800000" face="Arial" size="3"> Oracle10g Grid Computing with RAC</font><font size="3">" and of course this book costs $69.95 and they hope you buy it. The most expensive toilet paper if you ask me but okay...
And did he address the valid points posted on this site? I'm not sure but I bet he would be a darned good politician. I see his words but they don't have any meaning. I'm not even sure if he agrees or disagrees with the IHOC...

RE: Do you have lots of pictures of yourself?
My parents have lots of those small transparent slides stored in several dozens of large boxes and I am on about one-third of those. My parents also have this big projector so we can all see them when we're bored which fortunately almost never happens. My dad is planning to scan them all in his computer but fortunately he still hasn't found any time for that either. I'm not that fond of pictures of me because I always tend to have a funny look, or an angry look, or i've spilled something over my clothing or whatever. So I'm happy about the way those pictures are stored right now. [:)]

RE: How many web design rules can I break in one project?
I came, I saw, I went blind from the color-scheme...
Some people need to be dipped in tar and feather and then kicked out from any civilized area. Let them waste their time on some deserted island with one coconut palmtree, lots of sand and a view over the ocean in all directions. Webdesigners like this one should be castrated to avoid them reproducing and producing more bad webdesigners...

RE: Even on a more basic level
Hey geys, you do realise that this only makes a difference when you're doing some calculation about half a billion times, or so, don't you? (And yeah, I've learned some basic assembler.)
On the lowest level, you'd get this for A += B:
mov ax, [A]
add ax, [B]
mov [A], ax
However, you can also do this in reverse order:
mov ax, [B]
add ax, [A]
mov [A], ax
at a level this low, it just doesn't matter in which order the calculations are done since the system will need to use some register for the calculations to begin with. So at the lowest level, no difference...
The problem however is at slightly higher levels where the compiler is generating code that will e.g. check for numerical overflows. something like 255 + 255 would never fit in a datatype of 1 byte so there needs to be some bounds checking. And only in such cases the you might get some better optimization results. But still, it doesn't change the fact that for any calculation there's always a need for one register for the result. Basically, any compiler will just load the first value, add the following values and then return the result.
The same can be used at the higher levels. When you use an object-oriented language that will allow you to overload operators then any use of those operators on an object will just create a new object. Thus when doing something like A = B + A, the compiler would start by creating a new object C and assign the value of B to C. It would then add the value of A to C. Finally A will be freed and point to C. The same happens when you say A += B, except in a slightly different order. It will create C, first load it with value A and then add value B before freeing A and then letting A point to C.
Don't forget, objects are basically just nothing more than pointers.
However, you could try to implement a faster solution for A += B by just adding B to A directly. That would indeed save the memory allocation for C and you wouldn't need to free the old A. But not all compilers will build code like that and just do it similar as A = A + B. On the other hand, some compilers will be smart enough to recognise that A = A + B can be optimized to A += B and will optimize the final output. It all basically depends on how the compiler is optimizing object-oriented code that supports operator overloading. And of course how people implement their own operator overloading code.
Still, at the lowest level we're still talking about registers and data in memory. And at this lowest level it's still done by first loading the first value in a register, then adding the next values and finally return the value of the register to the data location. At this point there's really no speed gain, unless you have your data stored in registers to begin with.
The speed gain comes from the overloaded operators, where objects need to be created to hold the result value while another object needs to be freed because it's not required anymore. Then again, working at higher levels will slow you down anyways. And if you really need to do billions of calculations in a very small amount of time, you shouldn't use things as complex as objects. (Yet if you use .NET then you have no other choice...)

Wow. I've been gone for a while, wasn't I? [:D] Yeah, well... So many things to do and so little time to do them all in...
About my site, my webhost decided to upgrade their systems and then
make it more user-friendly. For example, they reorganised the folder
structure and changed a few other things that crashed several of my
Delphi ASP.NET applications. Still haven't found time to fix that too.
AndHolland? That's the name of the two provinces in the west of the
Netherlands. We have a Northern part and a Southern part which used to
be one bigger Holland in the past but due to some silly wars it's split
up in two. Almost according to some religious borders, with the
Northern part more Protestant and the Southern part more Catholic.
Nowadays it's more like the Northern part are Ajax-supporters and the
Southern part are Feyenoord Supporters. (Both are soccer-teams.) There
are more teams in these provinces, of course, but these are the real
big names here.
