  • SQL restore from single file db to filegroup

    - by Mauro
    I have a 180GB MOSS 2007 database whose maintenance (i.e. backups and restores) are becoming a problem. Part of the issue can be resolved by splitting the three content sites down into their own site collections, however this will likely still leave me with a 100gb DB to deal with. Whilst this isnt entirely problematic for SQL it does mean that backups / restores take far too long. my idea is to split each of the databases to 30gb files, then to import the content into them which should distribute the content across the file groups,making it much easier / faster to backup/restore. Is there a way to backup from a single file and restore to a filegroup? If i have the wrong understanding of filegroups then I'm more than happy to find out other methods of managing the size of databases.

  • super light software development process

    - by Walty
    hi, For the development process I have involved so far, most have teams of SINGLE member, or occasionally two. We used python + django for the major development, the development process is actually very fast, and we do have code reviews, design pattern discussions, and constant refactoring. Though team size is small, I do think there are some development processes / best practices that could be enforced. For example, using svn would be definitely better than regular copy backup. I did read some articles & books about Agile, XP & continuous integration, I think they are nice, but still too heavy for this case (team of 1 or 2, and fast coding). For example, IMHO, with nice design pattern, and iterative development + refactoring, the TDD MIGHT be an overkill, or at least the overhead does not out-weight the advantages. And so is the pair programming. The automated testing is a nice idea, but it seems not technically feasible for every project. our current practices are: svn + milestone + code review I wonder if there are development processes / best practices specifically targeted on such super light teams? thanks.

  • Logging in with a different password than the database password, PHPMyAdmin

    - by Andrew M
    I am trying to install PHPMyAdmin on my server to manage my MySQL databases. Right now I have only one I want to add, but I would like to be able to manage multiple databases from the same account on PHPMyAdmin. How would I configure PMA so I could login with "andrew" and a password of "examplepassword" instead of the annoyingly long and unchangeable database user and password I am provided (ie. db3483478234, password of random characters)? I can't seem to find an area to specify a different password than the regular database username and password.

  • simple script to backup PostgreSQL database

    - by Mick
    Hello I write simple batch script to backup postgeSQL databases, but I find one strange problem whether the pg_dump command can specify a password? There is batch script: REM script to backup PostgresSQL databases @ECHO off FOR /f "tokens=1-4 delims=/ " %%i IN ("%date%") DO ( SET dow=%%i SET month=%%j SET day=%%k SET year=%%l ) SET datestr=%month%_%day%_%year% SET db1=opennms SET db2=postgres SET db3=sr_preproduction REM SET db4=sr_production ECHO datestr is %datestr% SET BACKUP_FILE1=D:\%db1%_%datestr%.sql SET FIlLENAME1=%db1%_%datestr%.sql SET BACKUP_FILE2=D:\%db2%_%datestr%.sql SET FIlLENAME2=%db2%_%datestr%.sql SET BACKUP_FILE3=D:\%db3%_%datestr%.sql SET FIlLENAME3=%db3%_%datestr%.sql SET BACKUP_FILE4=D:\%db14%_%datestr%.sql SET FIlLENAME4=%db4%_%datestr%.sql ECHO Backup file name is %FIlLENAME1% , %FIlLENAME2% , %FIlLENAME3% , %FIlLENAME4% ECHO off pg_dump -U postgres -h localhost -p 5432 %db1% > %BACKUP_FILE1% pg_dump -U postgres -h localhost -p 5432 %db2% > %BACKUP_FILE2% pg_dump -U postgres -h localhost -p 5432 %db3% > %BACKUP_FILE3% REM pg_dump -U postgres -h localhost -p 5432 %db4% > %BACKUP_FILE4% ECHO DONE !

  • hosting site on one web server and accessing a database on another

    - by tombull89
    I'm fairly sure this is the right place for this question, but if not please move it to the the right site. I have a number of sites on a 1and1 package (yeah, I know...) and I also have a subdomian that belongs to a college tutor. I have been playing around with PHP and MySQL databases on the subdomian site and would like to know if it is possible to run a database driven (i.e. blog) on one of my 1and1 sites. I could upgrade my package but if I'm only going to gain database functionality I'm not sure if I want to do it. Also, as 1and1 don't use cPanel I'm wondering how the databases would be managed...but I'll worry about that when (if) the time comes. Cheers!

  • Looking for something like Google's Picasa [closed]

    - by Skizz
    I almost like Picasa, but there are two issues that irk me and I wondered if anyone knew of an application that does what Picasa does but without the following problems: Network drives. Picasa is hopeless with network drives. Ideally, I'd like photos to be stored remotely and thumbnail databases to be stored locally with a client-server set-up to update client databases. The main aim is to get updates propagated to clients efficently, reduce network bandwidth and have quick browsing on the client. It needs to be snappy when used over a wireless network. This is just a minor point but the folder view looks awful, especially when it uses those tiny thumbnails. (Also, what is it with folders being drawn vertically. Having spent years looking at folders orientated horizontally, turning them on their side looks so wrong.)

  • mysql single database relocation

    - by asdmin
    I would like to know if it's possible to operate different databases on different filesystem locations. Background: we are a hosting service, which hosts mysql, web, and smtp to it's customer, but all our services (sql, smtp, http) are located in a different place. We are going to assign a single logical volume to a customer, which will accommodate the customer's mailing, weppages and (hopefully) sql database. Web pages and mailing are already covered, but I am not able to find a configuration setting which would enable me to specify the location of a database (the directory where mysql stores the DB). Let me please highlight, the target here is to relocate different databases to different locations in the filesystem, not moving them from a single place to an another (single) place. Also please do not bother answering with soft and hard symbolic links. ;) Thanks

  • Upgrading from MySQL Server to MariaDB

    - by Korrupzion
    I've heard that MariaDB has better performance than MySQL-Server. I'm running software that makes an intensive use of MySQL, thats why I want to try upgrading to MariaDB. Please tell me your experiences doing this conversion, and instructions or tips. Also, which files I should take care of for making a backup of MySQL-Server, so if something goes wrong with MariaDB, I could rollback to MySQL without issues? I would use this but i'm not sure if it's enough to get a full backup of MySQL-Server confs and databases mysqldump --all-databases backup /etc/mysql My Environment: uname -a (Debian Lenny) Linux charizard 2.6.26-2-amd64 #1 SMP Thu Sep 16 15:56:38 UTC 2010 x86_64 GNU/Linux MySQL Server Version: Server version 5.0.51a-24+lenny4 MySQL Client: 5.0.51a Statistics: Threads: 25 Questions: 14690861 Slow queries: 9 Opens: 21428 Flush tables: 1 Open tables: 128 Queries per second avg: 162.666 Uptime: 1 day 1 hour 5 min 13 sec Thanks!

  • Tunneling over HTTP

    - by Morgan
    Hello, I have a network at work that is locked behind a firewall and Internet connection is available only by using a proxy server. At work, I can connect to databases that are distributed across the network. However, at home, I cannot connect to the proxy server or the databases. How can this be done? I can access my workstation via LogMeIn, so I can install anything on it. I thought of installing some kind of tunneling mechanism in my workstation. Then, at home, I could connect to this mechanism, which would in turn do the required connections. So essentially, what I'd like to do can be represented by the following diagram: Home = Workstation = Database. For example, whenever I connect to, say, 10.140.0.1:1234 at home, this would be redirected to 10.140.0.1:1234 of my Workstation, because 10.140.0.1:1234 is only available through the corporate network. NOTE: I'm using Windows XP.

  • Installed Percona mySQL on CPanel but getting an error

    - by user1227914
    I installed Percona mySQL on my fresh CPanel server (no databases yet) according to: http://www.ecommy.com/linux/install-...el-environment Everything seemed to be OK and the server also starts fine, except some commands return this error: root@server [/var/lib/mysql]# mysql -A -sN information_schema -e "select * from user_statistics;" mysql: unknown variable 'innodb_file_per_table=1' root@server [/var/lib/mysql]# mysql -A mysql: unknown variable 'innodb_file_per_table=1' In my /etc/my.cnf I have: [mysql] innodb_file_per_table=1 userstat_running=1 I am planning on using InnoDB for the databases.

  • Forgot password to development database

    - by ninja08
    I've created a database using terminal while following along with a tutorial. Although I had a lot of trouble getting the databases to install. Now after finally getting it to work I changed a few things, actually just the name of the database using the rake command to just "next". The password should be 'secret password'. How can I change the password or find out what it is or change it? It doesn't seem to be edited my databases.yml file with the password, especially since it still just says 'root' as username with now password in there.

  • SSRS Errors "Use Local", even though I am

    - by Corey Coogan
    I am at a loss. I posted this on SO, but think this is probably a better place. I have searched high and low and don't know what to do. I am running SQL Server Web Edition on Server 2008, which only supports local databases. I am trying to connect to localhost, but when I test my connection, I get this error. The feature: "The edition of Reporting Services that you are using requires that you use local SQL Server relational databases for report data sources and the report server database." is not supported in this edition of Reporting Services. The DB was upgraded from SQL Express and when I select @@version, it says it's Web Edition. I've tried rebooting and that seemed to fix it, but only for a little while.

  • postgresql creating and managing users

    - by MalphasWats
    I've tried a few times to get postgresql running on a couple of different linux boxes, but I've always ended up binning it and going back to MySQL because I can't get my head around how to create and manage users. This time around, I've actually gotten as far as being able to log in with my own account, but I created the account with the createuser command and it has a different password to my actual user account. What I'd like to be able to do is log in as me to create databases, users and assign database permissions, but then have an account that is separate and doesn't have an account on the server to use with my web app. Does anyone have a good step-by-step guide for complete morons that goes through creating users and assigning access to various databases in postgresql?

  • Being pressured to GOTO the dark-side

    - by Dan McG
    We have a situation at work where developers working on a legacy (core) system are being pressured into using GOTO statements when adding new features into existing code that is already infected with spagetti code. Now, I understand there may be arguments for using 'just one little GOTO' instead of spending the time on refactoring to a more maintainable solution. The issue is, this isolated 'just one little GOTO' isn't so isolated. At least once every week or so there is a new 'one little GOTO' to add. This codebase is already a horror to work with due to code dating back to or before 1984 being riddled with GOTOs that would make many Pastafarians believe it was inspired by the Flying Spagetti Monster itself. Unfortunately the language this is written in doesn't have any ready made refactoring tools, so it makes it harder to push the 'Refactor to increase productivity later' because short-term wins are the only wins paid attention to here... Has anyone else experienced this issue whereby everybody agrees that we cannot be adding new GOTOs to jump 2000 lines to a random section, but continually have Anaylsts insist on doing it just this one time and having management approve it? tldr; How can one go about addressing the issue of developers being pressured (forced) to continually add GOTO statements (by add, I mean add to jump to random sections many lines away) because it 'gets that feature in quicker'? I'm beginning to fear we may loses valuable developers to the raptors over this...

  • apt - Remove not configured package

    - by madflow
    I have a Linux-Mint Debian Edition System. When I install sendmail I get an infinite loop. Reading configuration from /etc/mail/sendmail.conf. Validating configuration. Creating /etc/mail/databases... Reading configuration from /etc/mail/sendmail.conf. Validating configuration. Creating /etc/mail/databases... When I try dpkg --configure -a it is the same. Now I want to simple remove sendmail from the installation queue - but I can't simply do that, because apt-get always wants to configure sendmail first. Is there a way to force apt-get to remove sendmail or set it to "configured" - even though the package is not properly configured?

  • How I May Have Taken A Wrong Path in Programming

    - by Ygam
    I am in a major stump right now. I am a BSIT graduate, but I only started actual programming less than a year ago. I observed that I have the following attitude in programming: I tend to be more of a purist, scorning unelegant approaches to solving problems using code I tend to look at anything in a large scale, planning everything before I start coding, either in simple flowcharts or complex UML charts I have a really strong impulse on refactoring my code, even if I miss deadlines or prolong development times I am obsessed with good directory structures, file naming conventions, class, method, and variable naming conventions I tend to always want to study something new, even, as I said, at the cost of missing deadlines I tend to see software development as something to engineer, to architect; that is, seeing how things relate to each other and how blocks of code can interact (I am a huge fan of loose coupling) i.e the OOP thinking I tend to combine OOP and procedural coding whenever I see fit I want my code to execute fast (thus the elegant approaches and refactoring) This bothers me because I see my colleagues doing much better the other way around (aside from the fact that they started programming since our first year in college). By the other way around I mean, they fire up coding, gets the job done much faster because they don't have to really look at how clean their codes are or how elegant their algorithms are, they don't bother with OOP however big their projects are, they mostly use web APIs, piece them together and voila! Working code! CLients are happy, they get paid fast, at the expense of a really unmaintainable or hard-to-read code that lacks structure and conventions, or slow executions of certain actions (which the common reasoning against would be that internet connections are much faster these days, hardware is more powerful). The excuse I often receive is clients don't care about how you write the code, but they do care about how long you deliver it. If it works then all is good. Now, did my "purist" approach to programming may have been the wrong way to start programming? Should I just dump these purist concepts and just code the hell up because I have seen it: clients don't really care how beautifully coded it is?

  • SQL Transactional Replication snapshot not applying

    - by dmch2
    Hi, I'm using SQL Transactional Replication with pull subscriptions to replicate databases (hosting their own distribution database) from several servers across a VPN to a central server. I've got the first 2 databases working fine but the 3rd one is causing me problems. My subscription server is SQL 2008, the source systems are all SQL 2005. The source databases are a few 100Mb in size and contain audit data so are simply growing slowly by adding new records at approx 1kb a second. As far as the replication monitor, Agent logs and event logs show everything is working fine - except that no data appears in my subscription database. The distribution agent doesn't seem to want to read the snapshot (and hence the initial state and schema) from the publisher. New transactions aren't applied although they do seem to be arriving OK as the replication monitor shows things like '5 transactions with 10 commands were delivered'. I would expect (as in previous times) to see statements about data being BCPed in the replication monitor. The snapshot is on the publisher on a shared folder. The subscriber can view the snapshot OK (\\repldata) and the alt snapshot folder is pointing at it. But the distribution agent doesn't seem to be making an attempt to do read it. I tried changing the snapshot path to something that's incorrect and didn't even get an error saying that it couldn't access it. After lots of googling etc I found that sp_MSget_repl_commands is called by the subscriber on the distribution database on the publisher. Running a profiler I can see that it's only called for one agent Id. After a reinit it's called for sequence number 0x0 as expected so I thought that would mean it's would look for the snapshot. However, looking on the publisher I see that there's data for two agents - the snapshot agent and the log reader agent (which is being queries). So I guess I need to tell the distribution agent to get the data for both. But how? and more importantly - why? It worked fine on the other two servers I've replicated. I'm not an SQL novice but this is pretty much my first go at replication so don't be afraid to accuse me of missing something obvious/stupid! I can get log files (eg from the distribution agent) if you want but they don't seem to have any errors in them - it just starts up and starts applying log reader agent changes. Cheers Dave

  • MySQL 5.0 Unavailable but still working every monday morning

    - by user1578031
    So I have a MySQL server with 4-5 databases and every monday morning, I can't login with PHPmyAdmin or the cmd line tools or options and the funny thing is the connection can be made later in the day around 3:30 - 4PM. I can't replicate the issues on any dev boxes and cant upgrade to 5.5 for a number of reasons. I want to try and poll the sql databases with a simple script and just connect to it and then disconnect. I'm not very good with SQL but would like to know if anyone could help with a script which I can automate to run sunday every 30mins or so, to see if the issue can be stopped by the database being connected to over the very quiet period of sunday... After this im out of ideas and have to wait for the HW/SW refresh to get 5.5 on there...

  • Ensuring quality of your software and code

    - by Filip Ekberg
    When I usually write code I follow some guidelines to ensure that my code has a certain standard and I as any other developer try to ensure that my code and software is of quality. Try to focus on the programming and not the understanding of the domain or any other pre-programming steps. These are the following steps I live by: Writing unit tests Make it fail ( no code ) Make it Work ( working code ) Analysing abstraction Extracting methods Exteract interfaces Refactoring In addition to the above which is a part of refactoring, I also try to refactor the code with good tools such as ReSharper, CodeRush or others. The question; What is the next step? Commenting the code is trivial and shouldn't even have to be mentioned, but updated comments and xml-comments where it's needed / everywhere is something that I try to have. But all the above helps he ensure that other developers might understand my code, that the code has some sort of quality and follows naming standards. It does however not ensure any product quality. I am looking for tools for post-development quality ensurance, such as profilers and how one would use these tools to increase product quality.

  • SQL Server database constantly restarting

    - by Michael Itzoe
    We have SQL Server 2008 Express installed on a Windows 2003 server. Looking at the event log, one of the databases appears to be restarting anywhere from every couple seconds to every 15 to 30 minutes. This server hosts about half a dozen databases; the problem is with only one. This database is also the onle one comprised of multiple schemas (not just dbo). There are thousands of events going back several months. There doesn't seem to be any affect on the website using the database, nor does any data appear to be corrupted or compromised. I'm not a DBA, so I don't even know where to look for causes to this. Any suggestions?

  • accessing external mysql server through "ssh tunnel" - any drawbacks?

    - by Max
    In an upcoming project I have a two server setup: one is the application server and another, already existing runs the mysql server with databases I need to access. I contacted the server admin of the mysql server and the only way I can access the remote mysql databases is via "SSH tunnel". I have never done this before and never heard of it so far, so my question, are there any drawbacks, e. g. performance wise? Isnt it rather slow compared to directly accessing the mysql server on its default port?

  • How can I open a file as read-only from Windows Explorer?

    - by Daniel Daranas
    Is there an easy way to open a file as read-only from Windows Explorer? My inmediate interest is in a Microsoft Access file. I am doing some sanity checks in old MS Access databases and I see that their date is automatically updated when I open them. I don't like this, since it will look like all the old files have been modified today. I am working with Windows XP. Update: As Yoda said, "Do, or do not. There is no try." In my case, it was "do not". I ended up copying the entire (big) folder tree to MyDocuments, and then opening all the databases from there.

  • Command-line tool to search for file names on offline backup drives

    - by halloleo
    I am looking for an open-source (command-line) tool to register and search all my (backup) drives on a file name level. I want to search for file and folder names preferably written as regular expressions or file glob patterns. The external drives contain just normal HFS and NTFS filesystems. The backups are done via direct file copy. Requirement is that the tool compiles on OS X and works without each of the drives attached, but rather pointing me to the drive in case a drive contains a file with the pattern I searched for. At the moment I use a hand-knit script solution with locate databases, one for each external backup drive, but this is rather cumbersome, because locate itself can accesses only one database at a time and does not contain any management system for all the indices/databases. Are there any other tools out there for this?

  • Migrating Split Access Database from one domain to another (not working, details in Q)

    - by Expo_Rob
    Some background: I'm a programmer, not a network administrator, who has been asked to migrate some accounting software (Integrated Office Accounting version 3.2) from an existing domain (OLD_NETWORK) to a new domain (NEW_NETWORK). No-body at the office knows how it works under the hood. It is a split Access 2000 database with the back-end shared and on a file server (which is also the DC) using mapped drives. The DC is NT Server 4 SP 6. The new server is server 2003. The two networks are running independently (ie: two computers on each desk). I have been able to get new computers set up on NEW_NETWORK and working with the IOA software just perfectly but for one problem: The company here uses other entirely separate databases which access the tables IOA maintains (specifically the 'customers' table) via links. To switch between these systems, you press F11 then File-Open the appropriate database and away you go (this is necessary to maintain the permissions that the IOA system uses to protect the customers table). The entire database is Access 2000, the links go to other Access databases, SQL-Server is not involved in any way, nor is a migration to SQL server likely. If I can't migrate anything over, everything will stay as it is, and the NEW_NETWORK computers will not be used. The problem: When I try and update these seperate databases (I shall call one "BANK_ACCOUNT", but the name does not matter), it says "this recordset cannot be updated". It also will sometimes not pull information out of the 'customers' table (ie: date_entered) when looking at a report of everyone who opened a bank account on a certain day (ie: today). I have tried: Giving 'everyone' full control via. shared directory permissions Giving 'everyone' full control on a file system level Checking the permissions within Access (everyone has full read/write on all tables) Copying the entire server contents from one file server to another (ie: xcopy everything) Copying the entire local client files from one computer to another, putting them in the exact same position in the file system, with the same permissons (or full control to 'everyone'). Running as an Administrator Taking one of the NEW_NETWORK computers, having it join OLD_NETWORK and run the software (direct copy from a working system with identical drive mappings), this did not work Weeping openly My Question: Is there anything else I can try? (sorry for this being so long)

  • NoSQL with MongoDB, NoRM and ASP.NET MVC

    - by shiju
     In this post, I will give an introduction to how to work on NoSQL and document database with MongoDB , NoRM and ASP.Net MVC 2. NoSQL and Document Database The NoSQL movement is getting big attention in this year and people are widely talking about document databases and NoSQL along with web application scalability. According to Wikipedia, "NoSQL is a movement promoting a loosely defined class of non-relational data stores that break with a long history of relational databases. These data stores may not require fixed table schemas, usually avoid join operations and typically scale horizontally. Academics and papers typically refer to these databases as structured storage". Document databases are schema free so that you can focus on the problem domain and don't have to worry about updating the schema when your domain is evolving. This enables truly a domain driven development. One key pain point of relational database is the synchronization of database schema with your domain entities when your domain is evolving.There are lots of NoSQL implementations are available and both CouchDB and MongoDB got my attention. While evaluating both CouchDB and MongoDB, I found that CouchDB can’t perform dynamic queries and later I picked MongoDB over CouchDB. There are many .Net drivers available for MongoDB document database. MongoDB MongoDB is an open source, scalable, high-performance, schema-free, document-oriented database written in the C++ programming language. It has been developed since October 2007 by 10gen. MongoDB stores your data as binary JSON (BSON) format . MongoDB has been getting a lot of attention and you can see the some of the list of production deployments from here - http://www.mongodb.org/display/DOCS/Production+Deployments NoRM – C# driver for MongoDB NoRM is a C# driver for MongoDB with LINQ support. NoRM project is available on Github at http://github.com/atheken/NoRM. Demo with ASP.NET MVC I will show a simple demo with MongoDB, NoRM and ASP.NET MVC. To work with MongoDB and  NoRM, do the following steps Download the MongoDB databse For Windows 32 bit, download from http://downloads.mongodb.org/win32/mongodb-win32-i386-1.4.1.zip  and for Windows 64 bit, download  from http://downloads.mongodb.org/win32/mongodb-win32-x86_64-1.4.1.zip . The zip contains the mongod.exe for run the server and mongo.exe for the client Download the NorM driver for MongoDB at http://github.com/atheken/NoRM Create a directory call C:\data\db. This is the default location of MongoDB database. You can override the behavior. Run C:\Mongo\bin\mongod.exe. This will start the MongoDb server Now I am going to demonstrate how to program with MongoDb and NoRM in an ASP.NET MVC application.Let’s write a domain class public class Category {            [MongoIdentifier]public ObjectId Id { get; set; } [Required(ErrorMessage = "Name Required")][StringLength(25, ErrorMessage = "Must be less than 25 characters")]public string Name { get; set;}public string Description { get; set; }}  ObjectId is a NoRM type that represents a MongoDB ObjectId. NoRM will automatically update the Id becasue it is decorated by the MongoIdentifier attribute. The next step is to create a mongosession class. This will do the all interactions to the MongoDB. internal class MongoSession<TEntity> : IDisposable{    private readonly MongoQueryProvider provider;     public MongoSession()    {        this.provider = new MongoQueryProvider("Expense");    }     public IQueryable<TEntity> Queryable    {        get { return new MongoQuery<TEntity>(this.provider); }    }     public MongoQueryProvider Provider    {        get { return this.provider; }    }     public void Add<T>(T item) where T : class, new()    {        this.provider.DB.GetCollection<T>().Insert(item);    }     public void Dispose()    {        this.provider.Server.Dispose();     }    public void Delete<T>(T item) where T : class, new()    {        this.provider.DB.GetCollection<T>().Delete(item);    }     public void Drop<T>()    {        this.provider.DB.DropCollection(typeof(T).Name);    }     public void Save<T>(T item) where T : class,new()    {        this.provider.DB.GetCollection<T>().Save(item);                }  }    The MongoSession constrcutor will create an instance of MongoQueryProvider that supports the LINQ expression and also create a database with name "Expense". If database is exists, it will use existing database, otherwise it will create a new databse with name  "Expense". The Save method can be used for both Insert and Update operations. If the object is new one, it will create a new record and otherwise it will update the document with given ObjectId.  Let’s create ASP.NET MVC controller actions for CRUD operations for the domain class Category public class CategoryController : Controller{ //Index - Get the category listpublic ActionResult Index(){    using (var session = new MongoSession<Category>())    {        var categories = session.Queryable.AsEnumerable<Category>();        return View(categories);    }} //edit a single category[HttpGet]public ActionResult Edit(ObjectId id) {     using (var session = new MongoSession<Category>())    {        var category = session.Queryable              .Where(c => c.Id == id)              .FirstOrDefault();         return View("Save",category);    } }// GET: /Category/Create[HttpGet]public ActionResult Create(){    var category = new Category();    return View("Save", category);}//insert or update a category[HttpPost]public ActionResult Save(Category category){    if (!ModelState.IsValid)    {        return View("Save", category);    }    using (var session = new MongoSession<Category>())    {        session.Save(category);        return RedirectToAction("Index");    } }//Delete category[HttpPost]public ActionResult Delete(ObjectId Id){    using (var session = new MongoSession<Category>())    {        var category = session.Queryable              .Where(c => c.Id == Id)              .FirstOrDefault();        session.Delete(category);        var categories = session.Queryable.AsEnumerable<Category>();        return PartialView("CategoryList", categories);    } }        }  You can easily work on MongoDB with NoRM and can use with ASP.NET MVC applications. I have created a repository on CodePlex at http://mongomvc.codeplex.com and you can download the source code of the ASP.NET MVC application from here
