You would use the dictionary item to know WHERE to put the data in U2  
which file, attribute etc.  if you are talking multi-values (or deeper) 
then this could also be driven from the dictionary, which would provide you 
with the capability of performing some mapping 

UNLESS 

you are in the position to dictate the format of the file you are trying to 
import (aka upload?) into UV.

But, if you wanted to be able to map an arbitrary data source, as suggested by 
George, using a dictionary would allow you to achieve the result in a point  
click manner -- and depending on the dictionary could also ensure that you 
don't download incomplete or invalid data into an otherwise (hopefully) 
clean environment, setup defaults etc

Re: [U2] UPLOAD not DOWNLOAD

 Maybe you could give an example of why you would read the Dict for an
upload.

Since one of my free tools has already come up in the discussion :)

For my various versions of IMPORT (including BCI.IMPORT) dictionaries are
used for two reasons:

1. to identify which fields to update in each source, so it can be used like
a regular verb.
2. to handle calculated fields that may also need to be inserted based on
the import data.

Here's the usage for BCI.IMPORT to give an idea:

BCI.IMPORT
--

BCI.IMPORT by Brian Leach

Import SQL data into Universe.

Syntax
--

BCI.IMPORT [FROM datasoure]
  [AS username][PASS[WORD] password]
  [EXEC statement|{TEXT|SQL} statement]
  [PARAM parameter..]
  [FIRST rows]
UPDATES filename
  [FIELD] fieldname {$n|EXPR expression|@special|'value'}
  [CONV code][{NUMERIC|DATE|TIME}]
  [LIST 'xxx,xxx'][RELATES file][BETWEEN n AND m]
  [PATTERN xxx][operator][REQUIRED]
  [MAP 'code=value[,code=value]']
[UPDATES filename ...]

Operators:
--

{INSERTFIRST|INSERTLAST|INSERTPOS|INSERTAL|INSERTAR|INSERTDL|INSERTDR|ADD|SU
B}

Expressions:

EXPR[ESSION] 'Expression'

Expression is made up of:
   numbers  eg 1.23
   operatorseg +
   dictionary names eg SURNAME
   uV Basic functions   eg FIELD()
   @Variables   eg @UserNo
   import column $n eg $2

eg. EXPRESSION TRIM($1:' ':$2:' ':$3)
EXPRESSION $1 * PRICE
EXPRESSION SUM(LINE_TOTAL)

Specials:
-
{@USER|@DATE|@TIME|@LOGNAME|@IMPORTFILE|@WHO|@ROW}

Example:

BCI.IMPORT FROM mysource
   AS sa PASSWORD admin
   EXEC 'sp_getData' PARAM 'OPEN'
   UPDATES FILE1
  FIELD @ID $1 NUMERIC
  FIELD DATE @DATE
  FIELD NAME EXPRESSION '$3: :$4'
  FIELD CODE $9 LIST 'ACA,ACB,ACC'
   UPDATES FILE2
  FIELD @ID $4
  FIELD ENTRIES $1 INSERTLAST
  FIELD QTY $7 INSERT BETWEEN 0 AND 
  FIELD TOTQTY $7 ADD

I write a lot of my utilities to be re-usable in this way, to be used as
verbs.

Brian

Re: [U2] UPLOAD not DOWNLOAD

2012-10-27 Thread Manu Fernandes
hi John,

Depending what you are looking for,
- a generic ETL tool where you define
1) Extract data from a defineable source (remote sql, csv-xls-dbf-xml-json 
files, webservice result , ...) with extendable method
2) Transform the received clob to internal UV data representation (iconv, mv'ed 
representation, build multi-part unique key, ...)
3) Load into U2 files (update one or more uvfiles into a Transaction (db 
transaction + application transaction))

That's not  a routine that's  complex tool with a lot of params and 
subroutines :-p

I have it, writen in SB+, require SB+ at runtime, but it's not free. Please let 
me know if you can be interested.

-

- Anyway, If you search routines to import, write one  record on one uvfile per 
received record,  from some specific data source I'm ready to share my 
experience (sql, dbf, csv, mdb, xls, xml, ...).

Please put some detail of the source.

regards
Manu

Will, if you don't want interactive (manual mapping), there is no other way 
aside from using DICT items that can be used to automatically map from an input 
file to your UV file, unless you feel like re-programming and compiling each 
time to change which columns go to which attributes. And you still may wind up 
having to manually map anyway, if your DICT name/description don't match column 
headers at all. 

I'm sure you have converted your share of client supplied files, and they are 
rarely the same, in column heading names or order of columns, even the 
formatting of dates, countries, states, phone numbers.

Did you read Brian Leachs document?
I think the way he solved this was rather clever, using a TCL command to 
associate the columns to attributes, then once you've done it once per 
definition, you can set it and forget it.

Much more clever than writing an import routine for every new type of document.

Well, what you say below is exactly opposite of what I described.
Normally I would encourage anyone else to re-read what I wrote and
cite specific text which leads to the conclusions below - in this
case... nah.

The data source never needs to know anything about the target - that
would be silly.

And no, I didn't describe a process that goes the wrong way - you
said *into* Universe (not out from it) which is what I described.
Perhaps what confused you is that the code for going in both
directions looks exactly the same - which is one of the neat aspects
of the approach.

BTW, someone might suggest from my code that the retrieval from the
source is done in bulk while posting  to the U2 target seems to be
done with individual transactions. That could be the case and for
large loads I'd modify the code to aggregate the data into a
collection and then post that to U2 in a single transaction.

BTW, the terms UPload and DOWNload are hugely ambiguous, and I believe
you have defined the terms backwards here. When I download to my PC,
it is TO my PC, not away from it. When I upload to a web server, the
data is moving out. And yet you define UPLOAD not DOWNLOAD as
meaning  *into* Universe (not out from it). The terms IMport and
EXport are more explicit. Your reference to the Cedarville Download
utility is a clue to the confusion. Cedarville is using Download in
the context of the recipient of the information downloading
information to a more familiar format from the Unidata server. From
the perspective of everyone in this group, that would be an Export,
and going in the opposite direction would be an Import. So what you're
describing is an Import into U2 ... traditionally described as a
download.

It would be counter-intuitive to call a system which loads data *into* Universe

or dict items that any of us here can write. The only thing new about
any such ETL project is the other side, which just requires some

Once someone internalizes that, the rest is fairly easy with Any

 I'm confused about your mention of Dict items because I don't see
 how you use Dict items for Uploading.  I see how you use them for
 Downloading.  Maybe you could give an example of why you would
 read the Dict for an upload.
 
In a public forum we discuss options. That doesn't necessarily mean
you're going to get a complete solution, or a completely free one. The
irony of your inquiries is that even when people give you complete and
completely free solutions, you tend to argue with them and change the
scope of the request. So my approach with you is simply to provide a
fishing line and point to where the fishing is good, and leave it to
you to catch your own fish. We've discussed this many times over the
years...

Anyway, to answer your question, depending on what the remote source
is you can use local dict items as a schema for validating data. Part
of the ETL process often involves data validation and/or cleansing. In
a homegrown solution you can provide the exact same data that is
required for a relational database, the table, key, and field names,
and loop to process inbound data. For a simple solution just read the
dict items, get the attribute number, and you now know where to put
the data. The point here is that the external interface doesn't need
to know that the CustomerName data is in attribute 2, it  just
provides a column name and the data and your code works out where it
goes.

Since you asked, I'll also hop into my salesman shoes with an [AD]:
mv.NET includes a feature called Solution Objects where strongly typed
class libraries (DAL and BAL) are generated using U2 file
dictionaries. If the ETL code is abstracted to a middle tier, you can
use a class like this to load your data using simple object instances:

var sourceData = GetDataFromWherever(mySpecs);
for(var rnum =0; rnum+=1; rnumsourceData.Count) {
  var source = sourceData[rnum];
  var toU2 = new Customer() {
Name = source.CustName,
Balance = source.AccountBal,
LastPaymentDate = source.LDate,  ...
  }
  toU2.Save();
}

The Customer class and properties were generated from dict items, and
an exception will be thrown if the data is bad, thus providing some
level of data integrity. The data can be saved directly into the file,
or the Save method can be configured to execute a BASIC program which
further processes the data into the right format and locations. I will
be happy to consult with developers toward creation of solutions as
described here.
[/AD]

Once again, the solution depends on a proper definition of the problem
to be solved. The above code pattern can be used to move data from
_anywhere_ into U2, which is a valid response to your general query.

Now, as usual, feel free to change the scope of the problem to
completely invalidate the responses provided thus far.

Re: [U2] UPLOAD not DOWNLOAD

2012-10-26 Thread Wjhonson
Interesting.  I'm just reading the documentation and it addresses a few nagging 
things that were floating around in my head about how this wouldn't work.  
Brian gives me a framework I can work in, I probably won't use his code, but 
just the skeleton of the ideas and write my own parser to work in a similar way 
to how he explains his.

You could modify Brian Leach's freeware BCI.IMPORT tool which is designed for 
SQL / BCI imports. But looks relatively easy to modify for what you want ! ;-) 

With his permission, of course ! I just downloaded to have a peek... as I have 
been looking at his other tools lately...

There is also provision for multivalues so that's great!

Check out Brian's website... http://www.brianleach.co.uk/pages/freebies.htm

That goes the wrong way.
Download does not depend on knowing who is consuming what to create it's 
results.

So Upload should not need to have interactive consumption details either.
That's my take.

It's reads a source and decides on its own without the sources assistance where 
to put what.

You're coming at it more from a point of view of both sides *agreeing* on what 
data is in what position.
