I'd recommend a database, not a data warehouse. Sql Server Express would be an obvious choice to get started.

I just finished reading a book on deductive databases, which outlined the basics about Datalog and deductive databases (Deductive Databases and their Applications by M. Colomb, if anybody is interested). Now I wish to actually try using this acquired knowledge, and so here is the question.
What program do you advise using for somebody looking to work with Datalog for the first time (prefferably available for free for educational purposes)? I have been looking into it and thus far haven't found any software with it's own GUI and a good guide for newbies. (Most of them such as IRIS seem to be Java plugins, and I don't know how to make it work).
Have a good one.

What does the book suggest?
|
|
|
|

The book doesn't seem to suggest much of anything in terms of actual software to work with. It seems to be mostly about explaining Datalog on theoretical level (how the horn clause works within a database set-at-a-time environment and other concepts about it's inner workings) rather than outlining how to work with it on a specific platform.
Truth be told, as I am searching around, it seems there are no real Datalog focused platforms, just interpreters invoked as coding language libraries (for example IRIS for Java). The thing is, I have no idea how to make IRIS and it's libraries work. :/ Guess I will have to experiment around...

Doing it already. Hoping someone shows up who has screwed around with this before. Makes the search go faster.

Help you how? If you mean can someone write the code for you then I am afraid you have come to the wrong place.

Hi everyone,
First of all sorry for any mistake I might give as English it is not my natural language.
My issues is: I built a query where I had to join 8 tables. The query should only be returning 4 rows but instead it is returning 8 rows as one of the tables I'm using in the join's has a field type to identify , for example if it is source and destination(0 or 1). The final result should return only one row with either with source and destination information base on the type. Two different columns (source,destination) but same row.
Any ideas how to solve this?
I appreciate any help.
Many thanks.

Hi Michael,
Thanks for replying.
Please find below a sample of the SQL. It is not the real script but reflects the scenario I tried to describe.
"select shipId,number,reference,[weight],SA.typeOfAddress,addressLine as Source, addressLine as Destination
FROM Shipments AS S INNER JOIN ShipmentAddresses AS SA ON SA.shipmentId = S.shipId
INNER JOIN Addresses as A ON A.addressId = SA.addressId"
This query is returning 2 rows:
shipId | number | reference | weight | typeAddress| Source | Destination |
1 1 ref1 12 0 London Road London Road
1 1 ref1 12 1 LiverPool Lliverpool
I would like a single row:
shipId | number | reference | weight | Source | Destination |
1 1 ref1 12 London Road LiverPool
Note: the type of address in the first example of results was just to indicate that 0 is source and 1 is destination.
Many thanks for the help.

Try something like this:
SELECT
S.shipId,
S.number,
S.reference,
S.[weight],
SA.addressLine As Source,
DA.addressLine As Destination
FROM
Shipments As S
INNER JOIN ShipmentAddresses As SSA
ON SSA.shipmentId = S.shipId And SSA.typeOfAddress = 0
INNER JOIN Addresses As SA
ON SA.addressId = SSA.addressId
INNER JOIN ShipmentAddresses As DSA
ON DSA.shipmentId = S.shipId And DSA.typeOfAddress = 1
INNER JOIN Addresses As DA
ON DA.addressId = DSA.addressId

Hi Richard,
Sorry the delay in answering.
the strategy you described above worked perfectly on my real production scenario.
Many thanks.

Can you recreate the problem in a simple example on SQL Fiddle[^]? Without seeing your table structure, query, sample data, and expected output, it's almost impossible to answer your question.

I found the MS SQL database for a specific application and needed to change a record in the database. What needs to be changed is a field with the name of a pdf that the points to a server folder that holds all of the application pdf files. What I did was rename the record field to the correct new pdf file name and copy the new pdf file to the server pdf folder. When I try to access the pdf file from the application I select view pdf link and the new pdf does not opens. In the application when the same link was select the original pdf opened to show the pdf content. After that I tied to change the pdf field in the database back to the name of the original file name and now when I select the same link that worked before with the original pdf file that opened before it will not open and appears to have the same problem as what I changed for the new pdf. I made sure that the file is still in the application directory and everything is back to the way I started and it still does open either the original or updated file. When I checked both file permissions I don't see anything wrong. I don't know what could of caused this.

Debug through the application code and see what is being retrieved and the execution method for viewing the PDF file.

Hi All,
I am new to codesmith, but my company is using, I got a project which is using CodeSmith for ORM. But the source code doesn't have cst file, they only have .csp file. Is there anyway that I can create .cst file from .csp file?
Any help like a link or a suggestion or a code snippet would help, I am also searching but any help would be appreciated.
Thanks in advance.
Thanks,
Abdul Aleem
