• What is the best way to archive data in a relational database?

  - by GenericTypeTea

  I have a bit of an issue with a particular aspect of a program I'm working on. I need the ability to archive (fix) a table so that a change anywhere in the system will not affect the results it returns. This is the basic structure of what I need to fix: Recipe --> Recipe (as sub recipe) Recipe --> Ingredients So, if I fix a Recipe, I need to ensure all the sub recipes (including all the sub recipes sub recipes and so forth) are fixed and all its ingredients are fixed. The problem is that the sub recipe and ingredients still need to be modifiable as they are used by other recipes that are not fixed. I came up with a solution whereby I serialize (with protobuf-net) a master object that deals with the recipe and all the sub recipes and ingredients and save the archive data to a table like follows: Archive{ ReferenceId, (i.e. RecipeId) ReferenceTypeId, (i.e. Recipe) ArchiveData varbinary(max) } Now, this works great and is almost perfect... however I totally forgot (I'd love to blame the agile development mentally, however this was just short sighted) that this information needs to be reported on. As far as I'm aware I can't think how I could inflate the serialized data back into my Recipe Object and use it in a Report. I'm using the standard SQL 2005 report services at the moment. Alternatively, I guess I could do the following: Duplicate every table and tag the word "Archive" on the end of the table name. This would then give me an area of specific archive data... but ignoring my simplified example, there'd actually be about 15 tables duplicated. Add a nullable, non-foreign key property called "CopiedFromId" to every table that contains fixed data and duplicate every record that the recipe (and all it's sub recipes and all their sub recipes) touches. Create some sort of denormalised structure that could be restored from at a later date to the original, unfixed recipe. Although I think this would be like option 1 and involve a lot of extra tables. Anyway, I'm at a total loss and do not like any of the ideas particularly. Can anyone please advise the best course of action? EDIT: Or 4) Create tables specific to what the report requires and populate them with the data when the user clicks the report button? This would cause about 4 extra tables for the report in question.

• How may I teach that SOAP is not a reliable transport?

  - by Eduardo

  I need to teach that a HTTP SOAP call may be received but the caller may not get the response due to a network failure (among other problems). (This problem made WS-ReliableMessaging be developed) How would you guys show this problem to a web service developer so they can develop taking into account that duplicate messages may be received?

• Is there a pretty print for PHP?

  - by Aaron Lee

  I'm fixing some PHP scripts and I'm missing ruby's pretty printer. i.e. require 'pp' arr = {:one => 1} pp arr will output {:one = 1}. This even works with fairly complex objects and makes digging into an unknown script much easier. Is there some way to duplicate this functionality in PHP?

• How to disable automatic loading in NHibernate?

  - by Drevak

  This question might be a duplicate of this one: http://stackoverflow.com/questions/217761/nhibernate-disable-automatic-lazy-loading-of-child-records-for-one-to-many-rela I'd like to know if there is any way to tell nhibernate to do not load a child collections (best if it's with fluent Nhibernate) unless i do it manually with a query (keeping all the mappings!). The problem is that even turning off lazy loading the collections get eager-loaded automatically. I'd like that no collections are loaded unless I specify a fetchmode in my query.

• JavaScript/jQuery short hand function definitions

  - by Baddie

  I'm using a jQuery plugin that has its functions defined as such: $('#mydiv').pluginAction({ someproperty: val, format: 'mm hh', labels: ['yes', 'no', 'maybe'], labels1: ['never', 'always'] }); In my HTML page, I have multiple DIVs that have the same properties for format, labels, labels1, but different values for someproperty. Is there some type of JavaScript notation I can take advantage of to shorten the definition so that I don't have to have duplicate code?

• Get Criteria by associationPath

  - by niklassaers

  Hi guys, Every so often, I get a "org.hibernate.QueryException: duplicate association path: myAssociation". This is because the complex criteria I'm working with can define the same path in many places. I'd love to do something like Criteria association = myCriteria.getAssociation("wax"); if(association == null) association = myCriteria.createCriteria("wax"); Is there any such way that I can check if an association is already in place? Cheers Nik

• Multi Process Configuration

  - by user200937

  Hi, I have a product built out of multiple processes. Each process uses internally commons configuration. Does anyone have an idea how to manage the config? I.e. we do not want to duplicate variables so each process will be able to read them. Additionally, DB solution is no good, as we do not want to be dependent on DB for something like configuration. Thanks Yair

• How to create a drop-in replacement for an existing dll?

  - by Bogatyr

  Beyond creating a dll with all the same functions with the same interface and calling conventions, does the replacement dll need to exactly duplicate the export map including ordinal numbers of the original as well? So that not only explicit loading via GetProcAddress works, but implicit linking as well?

• Why can't I save my model with a generic relation twice in Django?

  - by e-satis

  I got a model TrackedItem with a generic relation linking to any model it is supposed to track. If I do that: t = TrackedItem(content_object=MyModel) t.save() t.save() I get : IntegrityError: (1062, "Duplicate entry '1' for key 'PRIMARY'") Indeed, the first save has created an entry with "1" as a PK. But the second save should not insert, it should update. How am I suppose to update a model I can't save twice? With an ordinary model I can save as much as I want.

• Are there any implementations of multiset for .Net?

  - by dangph

  I'm looking for a .Net implementation of a multiset. Can anyone recommend a good one? (A multiset, or bag, is a set that can have duplicate values, and on which you can do set operations: intersection, difference, etc. A shopping cart for instance could be thought of as a multiset because you can have multiple occurrences of the same product.)
