  • Recommended book for Sql Server query optimisation

    - by Patrick Honorez
    Even if I have made a certification exam on Sql Server Design and implementation , I have no clue about how to trace/debug/optimise performance in Sql Sever. Now the database I built is really business critical, and getting big, so it is time for me to dig into optimisation, specially regarding when/where to add indexes. Can you recommend a good book on this subject ? (smaller is better :) Just in case: I am using Sql Server 2008. Thanks

  • Unable to fetch Json data from remote url

    - by user3772611
    I am cracking my head to solve this thing. I am unable to fetch the JSON data from remote REST API. I need to fetch the JSOn data nd display the "html_url" field from the JSON data on my website. I saw that you need the below charset and content type for fetching JSON. <html> <head> <meta charset="utf-8"> <meta http-equiv="content-type" content="application/json"> </head> <body> <p>My Instruments page</p> <ul></ul> <script src="http://ajax.googleapis.com/ajax/libs/jquery/1.3/jquery.min.js"></script> <script src="http://ajax.googleapis.com/ajax/libs/jqueryui/1.10.3/jquery-ui.min.js"></script> <script type="text/javascript" src="http://code.jquery.com/jquery-1.11.0.min.js"></script> <script type="text/javascript"> $(document).ready(function () { alert("Inside the script"); $.getJSON(" https://pki.zendesk.com/api/v2/help_center/sections/200268985/articles.json", function (obj) { alert("Inside the getJSON"); $.each(obj, function (key, value) { $("ul").append("<li>" + value.html_url + "</li>"); }); }); }); </script> </body> </html> I referred to following example on jsfiddle http://jsfiddle.net/2xTjf/29/ The "http://date.jsontest.com" given in this example also doesn't work in my code. The first alert is pops but not the other one. I am a novice at JSON/ Jquery. i used jsonlint.com to find if it has valid JSON, it came out valid. I tested using chrome REST client too. What am I missing here ? Help me please ! Thanks in anticipation.

  • Dynamic swappable Data Access Layer

    - by Andy
    I'm writing a data driven WPF client. The client will typically pull data from a WCF service, which queries a SQL db, but I'd like the option to pull the data directly from SQL or other arbitrary data sources. I've come up with this design and would like to hear your opinion on whether it is the best design. First, we have some data object we'd like to extract from SQL. // The Data Object with a single property public class Customer { private string m_Name = string.Empty; public string Name { get { return m_Name; } set { m_Name = value;} } } Then I plan on using an interface which all data access layers should implement. Suppose one could also use an abstract class. Thoughts? // The interface with a single method interface ICustomerFacade { List<Customer> GetAll(); } One can create a SQL implementation. // Sql Implementation public class SqlCustomrFacade : ICustomerFacade { public List<Customer> GetAll() { // Query SQL db and return something useful // ... return new List<Customer>(); } } We can also create a WCF implementation. The problem with WCF is is that it doesn't use the same data object. It creates its own local version, so we would have to copy the details over somehow. I suppose one could use reflection to copy the values of similar fields across. Thoughts? // Wcf Implementation public class WcfCustomrFacade : ICustomerFacade { public List<Customer> GetAll() { // Get date from the Wcf Service (not defined here) List<WcfService.Customer> wcfCustomers = wcfService.GetAllCustomers(); // The list we're going to return List<Customer> customers = new List<Customer>(); // This is horrible foreach(WcfService.Customer wcfCustomer in wcfCustomers) { Customer customer = new Customer(); customer.Name = wcfCustomer.Name; customers.Add(customer); } return customers; } } I also plan on using a factory to decide which facade to use. // Factory pattern public class FacadeFactory() { public static ICustomerFacade CreateCustomerFacade() { // Determine the facade to use if (ConfigurationManager.AppSettings["DAL"] == "Sql") return new SqlCustomrFacade(); else return new WcfCustomrFacade(); } } This is how the DAL would typically be used. // Test application public class MyApp { public static void Main() { ICustomerFacade cf = FacadeFactory.CreateCustomerFacade(); cf.GetAll(); } } I appreciate your thoughts and time.

  • Data access layer using Linq to SQL

    - by Andrei Tanasescu
    I am building a c# - linq - sql server winforms/asp.net application, accessing a database. I would like my business logic layer to be easily testable, and that means not littering it with Linq database queries everywhere. What design patterns/ best practices are available for the following use cases - inserting/updating a new object - searching for an object - loading a bunch of related data into a sort of "presentation" object that could be displayed by various views ?

  • How should I lay-out my PHP login class?

    - by ThinkingInBits
    So, there is going to be one login form; however 1 of 3 types of members will be signing in member_type_a, member_type_b, member_type_c all of whom have some of the same properties, and some whom may have specific methods and/or properties to them. I want the class to be saved to a session variable for use with member area pages. Any suggestions on applicable design patterns?

  • How do I update the members of a MySQL SET Type?

    - by MachinationX
    I have a table of values, with one of the columns being of type SET. If it currently has the members ('a', 'b', 'c', 'd'), how do I add 'e' to the possible values? I realize that using a SET type is a little strange, and I'm unclear why one would use it instead of a foreign key to another table with the values of the set, but I didn't design the database in question, and can't change it that much. Thanks for your help!

  • Do you employ any tools for managing technical debt?

    - by Phil.Wheeler
    The site I work with on a day-to-day basis has its share of shortcomings and we often make design decisions to "get us by right now" with the intention of fixing those up later. I've found that making the time to actually go back and fix them, let alone remembering what the full list of to-do items is can be challenging at best. Can you recommend any tools, resources or tricks that help you effectively manage your technical debt?

  • Authentication Sceme for RESTful API used by desktop app.

    - by user346087
    I'm providing a RESTful API. This API is used by a third party desktop application. The API is currently secured using Basic Authentication. That isn't very secure because the credentials have to be stored in the client application. The communication between the desktop and API can also easily be intercepter. The desktop application also communicates with a third party server (run by the publisher of the desktop application) I am unable to figure out how the secure the API in a good way. Ideas?

  • Flex 4: use google APIs in RIA without server side code?

    - by grapkulec
    Just to confirm what I think I understand from reading about use of google APIs in RIAs (FLEX 4 and ActionScript) there is no way to connect to blogger API for example, directly from RIA because of google's crossdomain.xml file, right? So if I want to use their APIs to get some data like content of my mailbox or list of posts on my blog I have to have some code running server side and RIA would just use that code as httpservice to collect data from google? Or maybe I got it completly wrong?
