• PowerPivot and the Slowly Changing Dimensions

  - by AlbertoFerrari

  Slowly changing dimensions are very common in the data warehouses and, basically, they store many versions of the same entity whenever a change happens in the columns for which history needs to be maintained. For example, the AdventureWorks data warehouse has a type 2 SCD in the DimProduct table. It can be easily checked for the product code “FR-M94S-38” which shows three different versions of itself, with changing product cost and list price. This is exactly what we can expect to find in any data...(read more)

• SQL Server 2012 : Changes to system objects in RC0

  - by AaronBertrand

  As with every new major milestone, one of the first things I do is check out what has changed under the covers. Since RC0 was released yesterday, I've been poking around at some of the DMV and other system changes. Here is what I have noticed: New objects in RC0 that weren't in CTP3 Quick summary: We see a bunch of new aggregates for use with geography and geometry. I've stayed away from that area of programming so I'm not going to dig into them. There is a new extended procedure called sp_showmemo_xml....(read more)

• how to get 12 for joel test working in a small team of 3-4 on php website?

  - by keisimone

  Hi i read this inspired, i am asking for specific help to achieve a 12 for my current project. i am working in a team of 3-4 on a php project that is based on cakephp. i only have a dedicated server running on linux which i intend to have the website live on. and i have a plan with assembla where i am using its svn repository. that's it. i like to hear a major, impactful step towards answering each point raised by the joel test. by impactful i mean doing just this one thing would raise my project to scoring or close to scoring on that area of the joel test. lets begin: 1) do you have a source control system? I am very proud to say learning how to use svn even though we know nuts about branch/release policies made the biggest impact to our programming lives. and the svn repos is on assembla paid plan. Feel free to add if anyone thinks we can do more in this area. 2) Can you make a build in one step? i think the issue is how do i define as a build? i think we are going to define it as if tomorrow my dedicated server crashed and we found another server from another normal hosting provider and all my team's machines all destroyed, how are we going to get the website up again? my code is in svn on assembla. 1 step means as close to 1 button to push as possible. 3)Do you make daily builds? i know nothing about this. please help. i googled and came across this phpundercontrol. but i am not sure if we can get that to work with assembla. are there easier ways? 4)Do you have a bug database? we have not used the assembla features on bug tracking. ashamed to say. i think i will sort this out myself. 5)Do you fix bugs before writing new code? policy issue. i will sort it out myself. 6)Do you have an up-to-date schedule? Working on it. Same as above. estimates have historically been overly optimistic. having spent too much time using all sorts of funny project management tools, i think this time i am going to use just paper and pen. please dont tell me scrum. i need to keep things even simpler than that. 7)Do you have a spec? We do, but its in paper and pen. what would be a good template? 8)Do programmers have quiet working conditions? Well we work at home and in distributed manner. so .. 9)Do you use the best tools money can buy? We use cheap tools. we are not big. 10)Do you have testers? NO testers. Since we have a team of 3, i think i should go get 1 tester. even on a part time basis. so i should get this 1 part time tester test in what manner to extract maximum effects? should i get him to write out the test scenarios and expected outcomes and then test it? or i write the test scenarios and then ask him to do it? we will be writing the test cases ourselves using simpletest. i came across selenium. how useful is that? 11)Do new candidates write code during their interview? Not applicable. But i will do it next time i try to hire anyone else. hires or contractors alike. 12)Do you do hallway usability testing? Will do so on a per month or per milestone basis. i will grab my friends who are not net-savvy. they will be the best testers of this type. Thank you.

  Were you aware there are two versions of the Access .accdb file format? The 2007 “ACE” version and the 2010 “ACE” version both use different drivers. If you’ve tried to use the Access Database .accdb format on DiscountASP.NET servers and it failed you must have been using a Data file created with the 2010 version of Access. OK, you’re shouting at me right now for even suggesting Access Databases for Shared hosting, right? I agree, SQL Server is the way to go and I personally help a lot of developers...(read more)

• SQL Server 2008 R2 still requires a trace flag for Lock Pages in Memory

  - by AaronBertrand

  Almost two years ago, I blogged that Lock Pages in Memory was finally available to Standard Edition customers (Enterprise Edition customers had long been deemed smart enough to not abuse this feature). In addition to applying a cumulative update (2005 SP3 CU4 or 2008 SP1 CU2), in order to take advantage of LPIM, you also had to enable trace flag 845. Since the trace flag isn't documented for SQL Server 2008 R2, several of us in the community assumed that it was no longer required (since it was introduced...(read more)
