  • Entity Framework 5, separating business logic from model - Repository?

    - by bnice7
    I am working on my first public-facing web application and I’m using MVC 4 for the presentation layer and EF 5 for the DAL. The database structure is locked, and there are moderate differences between how the user inputs data and how the database itself gets populated. I have done a ton of reading on the repository pattern (which I have never used) but most of my research is pushing me away from using it since it supposedly creates an unnecessary level of abstraction for the latest versions of EF since repositories and unit-of-work are already built-in. My initial approach is to simply create a separate set of classes for my business objects in the BLL that can act as an intermediary between my Controllers and the DAL. Here’s an example class: public class MyBuilding { public int Id { get; private set; } public string Name { get; set; } public string Notes { get; set; } private readonly Entities _context = new Entities(); // Is this thread safe? private static readonly int UserId = WebSecurity.GetCurrentUser().UserId; public IEnumerable<MyBuilding> GetList() { IEnumerable<MyBuilding> buildingList = from p in _context.BuildingInfo where p.Building.UserProfile.UserId == UserId select new MyBuilding {Id = p.BuildingId, Name = p.BuildingName, Notes = p.Building.Notes}; return buildingList; } public void Create() { var b = new Building {UserId = UserId, Notes = this.Notes}; _context.Building.Add(b); _context.SaveChanges(); // Set the building ID this.Id = b.BuildingId; // Seed 1-to-1 tables with reference the new building _context.BuildingInfo.Add(new BuildingInfo {Building = b}); _context.GeneralInfo.Add(new GeneralInfo {Building = b}); _context.LocationInfo.Add(new LocationInfo {Building = b}); _context.SaveChanges(); } public static MyBuilding Find(int id) { using (var context = new Entities()) // Is this OK to do in a static method? { var b = context.Building.FirstOrDefault(p => p.BuildingId == id && p.UserId == UserId); if (b == null) throw new Exception("Error: Building not found or user does not have access."); return new MyBuilding {Id = b.BuildingId, Name = b.BuildingInfo.BuildingName, Notes = b.Notes}; } } } My primary concern: Is the way I am instantiating my DbContext as a private property thread-safe, and is it safe to have a static method that instantiates a separate DbContext? Or am I approaching this all wrong? I am not opposed to learning up on the repository pattern if I am taking the total wrong approach here.

  • SQL Server 2008 Spatial Index Performance

    The institution I work with has decided to migrate their database system to SQL Server 2008. One of the applications uses geospatial data, which consists of millions of rows.

  • Cleaning Up SQL Server Deployment Scripts

    Although, generally speaking, source control is the truth, a database doesn't quite conform to the ideal because the target schema can, for valid reasons, contain other conflicting truths that can't easily be captured in source control.

  • Using a PowerShell Script to delete old files for SQL Server

    Many clients are using custom stored procedures or third party tools to backup databases in production environments instead of using database maintenance plans. One of the things that you need to do is to maintain the number of backup files that exist on disk, so you don't run out of disk space. There are several techniques for deleting old files, but in this tip I show how this can be done using PowerShell.

    As I have been asked,  here to tidy up yesterdays post is the procedure my startup procedure calls along with the logging table deployed in the DBA database.

  • Supermicro motherboards and systems

    - by jchang
    I used to buy SuperMicro exclusively for my own lab. SuperMicro always had a deep lineup of motherboards with almost every conceivable variation. In particular, they had the maximum memory and IO configuration that is desired for database servers. But from around 2006, I became too lazy to source the additional components necessary to complete the system, and switched to Dell PowerEdge Tower servers. Now, I may reconsider as neither Dell or HP are offering the right combination of PCI-E slots. Nor...(read more)

  • Archiving SQL Server Data Using Partitioning

    Many companies now have a requirement to keep data for long periods of time.

  • How to separate production and test assets during development?

    - by bcsanches
    Hi Folks, this is like a complement for Assets Management, database or versioning system?. I am wondering about how to separate development, specially programmers assets from production assets? For example, if we keep all the assets on the same repository, how do you keep with programmers assets and final game assets? Do you keep a separate directory for each of those, allowing duplicates? Or do you use some fancy scheme for striping out the "development" and "test" assets from final build?

  • Registering domain during Christmas holidays

    - by arkascha
    One of the domain names I tried to register previously has been blocked by a domain grabber two days prior to my own attempt. That was about 1 year ago. The attempt to buy the domain from that person failed due to a totally exaggerated price. So I dropped the issue and watched the domain (offered at sedo.com). As expected there were no more offers, the domain was not sold. Now I learn from the whois database that the registration of that domain name ends on 25 Dec 2012 (Christmas holiday). This raises two questions for me, I fail to find reliable answers on the internet. So maybe someone experienced here can drop a statement or a hint: Is it reasonable that the domain name in question really will be free again when that date mentioned in the whois database up to when the domain is registered has passed? I certainly know that the registration can be prolonged, that is not what I mean. I expect (hope) that that domain grabber does not extend the registration, since it costs money and effort and he failed to sell the domain. Provided this is the case and the domain registration is not prolonged, is that date mentioned reliable? Or might it just be some 'default' date? I would like to try to register that domain name as soon as it is unregistered. Since that domain grabber registered that domain only two days before my own registration attempt I would like to prevent such annoying interference next time. So I ask myself: is it possible to register a domain name on a holiday? I mean not to send an email to my provider to do so on that day or before, but to actually have to process taking place as not to wait for 1-2 days after the unregistration? My own provider which I am very happy with does not offer such service on a holiday (which is perfectly understandable). They are 'still checking' if they can offer something automatic. I researched and did not find an answer to the question if that is possible at all. Is an automatic registration attempt on a holiday possible? Where can I do that? Is that reliable?

  • Where should I start and how to progress when learning Java EE

    - by danizmax
    I know basic stuff like, what are beans, jsp, servlet, jsf and how this stuff should work together. I know how to make basic jsp page with database query for example. Now I need to know what is the best path to learn all this stuff. My plan is to learn in this order: jsp (including persistance and JSTL) servlets + beans jsf The jump to frameworks (hibernate, struts, spring, etc) Also I'm not exactly sure about JSF, is it a must to make great pages or is it just a convenience to know?
