  37. Question 22. Does The Qvd Data Get Stored In An Rdbms Like Oracle, Or Is It In A File System?

    Answer :

    QVD files are stored in the file system.

  38. R Programming language Tutorial

  39. Question 23. What Is The Compression Factor For Qvd’s?

    Answer :

    QVD files are stored uncompressed. A QVD contains the physical representation of an in-memory Qlikview Table. This “RAM image” format is what allows an optimized QVD load to be so quick. The physical blocks of disk are read directly into RAM, “ready to go”. Because QVD is the RAM image, there is no compression.

  40. Pentaho Interview Questions

  41. Question 24. Can We Trace Back Qvd To Its Source?

    Answer :

    As of QV10SR2, the XML header in a QVD file contains the name of the QVW that created the QVD as well as file sources and database connections/SQL statements.

  42. PL/SQL Interview Questions

  43. Question 25. Why Is Sorting Not Possible While Loading Qvd?

    Answer :

    Sorting (ORDER BY) is only possible with Resident (already in memory) files. Sorting is not possible when reading from files.

  44. Pentaho Tutorial

  45. Question 26. Could You Go Over Again The Concept Of “forcing” Un-optimized Load For The Mapping Function, Respective To The Qvd?

    Answer :

    MAPPING tables may be loaded from a QVD, but it must be an un-optimized load (this is sometimes called “unwrapping”).


    MAPPING LOAD F1, F2 FROM sometable.qvd (qvd);

    The above mapping table will be created but it will appear to be empty when used in MAP USING or Apply Map(). No error, just no resulting mapping. One workaround is to create a condition that will cause an un-optimized load. We want all the rows, so we create an always-true condition that will return all rows.


    MAPPING LOAD F1, F2 FROM sometable.qvd (qvd)
    WHERE 1=1;
  46. Advanced SAS Interview Questions

  47. Question 27. The Use Of The Where 1=1 Is Something That Will Be Good For Mapping Fields In The Future Or Is Possible That Qlikview Will Determine That Where 1=1 Will Allow Optimization?

    Answer :

    Good question. We use WHERE 1=1 to force the un-optimized load required by MAPPING LOAD. I’m hopeful that if Qlikview were changed to consider 1=1 as an optimized load, they will also recognize that MAPPING LOAD should be non-optimized.

  48. MSBI Interview Questions

  49. Question 28. How Would You Handle The Need To Load Multiple Models (ie Multiple Qvws)?? I Don’t Think You Can Do Multiple Binary Loads, So What Do You Recommend?

    Answer :

    You can generate QVDs from each model and then load all the QVDs to form the larger model. You can generate all QVDs from a qvw with a simple loop. You can add this code to each of your model qvws.

    FOR i = 1 to NoOfTables()
    LET vTableName = TableName($(i)-1);
    LET vOutfile = '$(vTableName).qvd';
    STORE [$(vTableName)] INTO [$(vOutfile)] (qvd);
    NEXT i
  50. Question 29. How Are Qvd Refresh Scheduled?

    Answer :

    QVDs are created by script in a QVW executed by the reload process. Schedule the reload as you would the reload of a user facing qvw, using the Qlikview Enterprise Management Console (QEMC) or a batch file.

  51. Question 30. Is Qvd Optimized Load Really Worthwhile Since It Is Fairly Limited? In Other Words, Should We Load Data To The Memory Striving For Qvd Optimized And Then Work With The Memory Tables Within The Script?

    Answer :

    Optimized vs non-optimized load has two impacts: Load duration and Server RAM usage. If your application is relatively small or you do not have concerns about the impact, don’t spend time trying to maintain an optimized load. Some of the script techniques used to maintain optimized can make your script harder to follow.

    If, for a given document, you have concerns about load duration or RAM usage, then making the effort to maintain an optimized load would be worthwhile.

  52. Question 31. Can A Qvd Be Accessed From A As400 Db2 Database To Get Some Data?

    Answer :

    Nothing but Qlikview can read from QVDs, so no, DB2 cannot read directly from a QVD.

    In the same script that creates the QVD with the store statement: STORE mytable INTO mytable.qvd (qvd);

    You can also create a CSV copy for other consumers:

    STORE mytable INTO mytable.csv (txt);

    The csv file can be read by any number of programs, including an ODBC text driver or a bulk database loader. You can use QV to do the ETL and then push csv files back into a Data Warehouse, using something like SQL Server DTS or other data pump.

  53. Question 32. I’m Pulling Data From A Database Over A Slow Wan Link. Would Using A Qvd Speed This Up? If So, Would The Qvd File Reside On The Same Side As The Database Or At The End Of Wan Link (client Side)?

    Answer :

    Using QVDs could speed up your overall process by allowing multiple reloads to load from the qvd instead of going to the database over the slow WAN link. The QVD should live at the client end of the link – where the qvw is reloading.

  54. Question 33. If The Data Source Is Constantly Changing (such As Portfolio Management Software) Can We Refresh Qvds Frequently? Will This Overburden The Process?

    Answer :

    QVDs may be refreshed frequently. Exactly how frequently depends on your data volumes and architecture. Refreshing every 30 minutes is common, and I have seen intervals of 5 minutes. Frequent refresh of large volumes usually requires incremental load, which is covered in the Reference Guide and the Forums.

  55. VBA For Excel Interview Questions

  56. Question 34. If Add The Buffer Command Before Each Load Statement Pulling From Dbms, The First Execution Pulls From The Db But All After Are Incremental Loads Pulling From A File System Created Batch Of Qvds?

    Answer :

    The BUFFER prefix does not provide incremental load when loading from a DBMS. Subsequent reloads will load from the buffered file system QVD, but new rows will not be fetched from the database.

    When used with a load from txt files, BUFFER will provide automatic incremental load. Subsequent reloads will add new data from the file to the buffered QVD.

  57. Question 35. I Am Running Sbe Server So Documents Are Reloaded Right From The Documents Folder. What Is Your Recommendation For Location Of The Qvd Generator Documents? In Other Words, Do You Place Them In The Documents Folder Alongside Your Production Qvw’s?

    Answer :

    I recommend putting the QVD generators in a separate “Loaders” folder. Make this a mounted folder in QVS and schedule reloads as needed. Use NTFS permissions to hide the folder from standard AP users A number of questions were asked about the QVX format. I haven’t had much experience with QVX yet. Rob Patterson has indicated he will schedule a QlikLearn webinar specifically on the topic of QVX.

  58. Question 36. Does Qvx Also Have Two Types Of Load, Optimized And Not Optimized?

    Answer :

    No optimized load only applies to QVD.

  59. SAP BO Interview Questions

  60. Question 37. What Are The Other Differences Between Qvd And Qvx?

    Answer :

    QVD is a proprietary file format provided by QlikView for storage. Only QlikView software can read and write to QVD files.

    The QVX is in an open format performance file for storage of QlikView data. A customer or third party can create QVX files on any platform, without needing Qlikview software.

    QVD files will typically load faster than a QVX file.

  61. Question 38. Is Qvx Used As A Source To Other Source Systems Or Is It Used To Pull The Data From Source Systems Which Has No Odbc Provider?

    Answer :

    The use cases for QVX are still being discovered, and I’m sure we’ll see some interesting uses. The scenario I currently understand is to provide data to Qlikview when there is no ODBC provider.

  62. Question 39. What Are The Requirements For Installing Qlikview?

    Answer :

    There are several good home pages on the Internet about Windows installer.

  71. Question 46. How Much Ram Do I Need? Is There A Simple Way To Relate Ram Requirements To Data Volume?

    Answer :

    No, it depends on the data structure and the type of data. The more rows of data and the wider each record is in terms of number of fields the more RAM is needed. If a field contains many different distinct values more RAM is required than if the number of distinct values is low. Certain charts may demand a large portion of RAM while being calculated.

    Key difference is in terms of the database used. QlikView offers a quite simple visualization that matches the MS excel filtering. SAS is useful in case of Meta data while SPSS is good for analysis.

    In comparison of the above three, QlikView is most user friendly and fast in terms of generating diverse dashboards/templates.

    In terms of calculations, advanced statistics options are limited in QlikView.

    For market research and analysis SPSS has direct facility algorithms.

  129. Question 104. What Are Qlikview Annotations?

    Answer :

    With the new annotations collaboration object QlikView users can engage in threaded discussions about QlikView content. A user can create notes associated with any QlikView object. Other users can then add their own commentary to create a threaded discussion. Users can capture snapshots of their selections and include them in the discussion so others can get back to the same place in the analysis when reviewing notes and comments. QlikView captures the state of the object (current selections), as well as who made each note and comment and when, for a lasting record of how a decision was made.
