RE: Productivity metrics
Do the metrics take the impact of tools into account ? Some of the examples I've looked at seem to include all lines of code produced from an environment like Delphi or VB, even though 80% of this code is produced from the IDE. I'm sure the same would be true of tools like SB+, and certainly with our Viságe product, though in both cases this would be offset to a degree by the effort involved in smartening up dictionaries Many of the things that historically required hard code can now be reduced to parameter settings for an object - how do you measure this ? Or the flow through effect of changing an output conversion from, say, D2/ to D4/, in an active dictionary environment. The productivity impact is obvious - but how do you quantify that sort of gain ? especially when it may be tempered by the fact that other parts of an organization/system may still be using old fashioned, hand crafted PickBasic ? (I don't really want/need an answer to this, as I think the results could be skewed to show anything, and the time taken to gain the result/insight could be longer than the time taken to get the job done ?!?)

Productivity metrics
Hi all, IBM initiated a metric called Function Points that attempts to provide a means for measuring programming tools by the amount of code that has to be written in order to produce a program of a certain complexity. There have been several studies by which programming languages have been ranked in terms of lines of code (LOC) per function point (FP) Smalltalk, for example, is reckoned to have a ratio of 20 LOC per FP. Java and C++ come in around the 50 mark. Is anybody aware of studies that have applied this kind of scoring to the BASIC used in MV databases, or any other study that seeks to rank programming languages in terms of programmer producivity and that includes MV BASIC? Thanks Bob -- u2-users mailing list [EMAIL PROTECTED] http://www.oliver.com/mailman/listinfo/u2-users
Re: Productivity metrics
I've worked with the function point methods for some time and I don't think MV BASIC has been mapped. You could check with Dave Garmus, who is a central figure in FP (Google him, he comes up near the front). In order to do it you need to run some statistics against a number of carefully selected projects that have application function point counts and their source code. That hopefully will average out all the implementation variations. The other thing to do is try to interpolate using existing, measured langauges. Indeed it might be fair to say MV BASIC is more COBOL-like in productivity than traditional Dartmouth BASIC. Both have known LOC/FP ratios. A more careful assessment of where our BASIC lies relative to other languages would probably come up with a reasonably close ratio value.

RE: Productivity metrics
The other interesting thing I noted @ the HELLO WORLD site was that we had FULL source code for things like delphi - even though 99.9% was produced automatically from the IDE !

Meaningless then. You can write some pretty hairy nested stuff into a single 'C' statement. How is that counted? If you call a library function, do you count all the lines in that function? If you execute a SQL command under TSQL, how much of the SQL library is included in the tally? It's like those old programming competitions - write the shortest program in any computer language that prints itself, and so forth (before anyone pipes up, my entry: pg $0) I used a class generator a while back to generate VB classes to access a data source. The classes are horrible, complicated, long winded things - but since they were machine generated and provide just about every method I might need my productivity was actually improved by using them. A uvCase screen is built using a screen designer or from a short script. But the screen interpreter includes thousands of lines of Delphi code. Again, which is counted? As a measure it all sounds a bit pointless - I can't see how number of statements relates to programmer productivity when there are so many different ways to pare a moggie.
