Standardization

What is the difference between standard and of standard dimensions? That you can recommend in obiee?

Hello

As opposed to denormalization, the purpose of the standardization process is to reduce redundancy (same information stored more than once) and ensure the integrity of the data (the database contains valid information).
This is achieved by reducing the large entities (large, which means a large number of attributes) into several other, lesser entities that set contains the same information, but not repeat it.

There are methods such as 1NF, 2NF... to normalize the data...
Contains standardized... tables summary of data...
And denormalized tables contains data at the level of detail...

A tables dénormalisée can divided in n normalized number tables depends on your condition... at the level of the database...

Due to normalization, we find more tables that involves several joins and leads to have less performance...
Normalization tables are very easy to maintain and easy to build diagrams in Star...
With standard tables, we will have other than the star schema... (snowflake)...

2. that you can recommend in obiee?

A. Standardization-(Star always good schema for obiee).

Hope this helps

Thank you
Satya

  • Can I standardize the levels of audio in a single operation?

    I have a video which lasts 17 minutes, 15 sequences, and God knows how many clips.  The noise level is not as consistent as I wish it were, so I wonder if I can standardize all of the output with a single audio effect?  Or should I make it as it is and use the hearing on the rendering of MP4 files?

    I realize that this is not recommended, so I would appreciate being pointed in the right direction to avoid to be wrong in the future.  I ' v comes to be going to the ear and keeping everything below 0 dB.  I have a subscription to Lynda.com.

  • Standardize the size of smartshapes

    Hello

    I'm working on a training video in which we have clickable smartshape arrows on each page. I couldn't not all the same size, and it seems sloppy. Does anyone know how to standardize the size of the smartshapes? Please find below the reference photo.

    Thank you very much!

    Have you tried the option align (right-click with the toolbar or right) 'resize it to the same size?

    Why do you want those form buttons on each slide instead of on the master slide or timed for the rest of the project?

    If you insist on form on each slide buttons, create a style for each of the buttons on the form. When you put a button in the correct place, you can use the menu on the Options tab (button small hamburger/hot dog with top 5 lines on the right) and use 'Apply to all elements of the same style', which means that all form with the same style buttons will be positioned at the same place and have the same size. But you'll need two styles: one for the next button and the other for the back button.

  • standardize the rules of paragraph

    I inherited a large number of documents that use many styles that I'm trying to standardize. One thing that is obvious, for example, is that many use different weights of paragraph rules in their style. Is it possible for me to open a document and quickly define all the rules of paragraphs (when used) of a particular weight?

    I use CC 2014

    You can also set several properties on one line paragraph, then:

    Tell application "Adobe InDesign CC 2014"

    set the properties of each paragraph of each story in the active document to {rule above right indent: 0.1, rule above offset: 0.25, rule above left indent: 0.25, rule above line weight: 0.9, rule above tint: 50.0}

  • Degree of standardization of data

    Hi friends,

    Is identical to the normalization of the database normalization of data? This part of the job of the DBA?

    How many forms or level of standardization data? It is up to the 5th or 6th level?

    I heard this standardization of data and I tried to read again and again but I can not really fully understand :(

    Thank you very much

    Not within Oracle. Standardization of data is the down and dirty job to analyze your data in your business. If you want to say that your employee table has a primary key on the color of the hair to Oracle, oracle is quite happy to create this table and PK.

  • Help on Standardization

    Hello

    I need help on normaliation.


    What is the maximum number of columns that we can keep in the table or when we need to standardize our table if column exceeds the number of columns in a database design?

    Thank you

    Oradba11

    There is no actual limit, but if your table has likely more than 100 columns, it is not standardized.

    I don't have any document (in English), but you could start with the Wikipedia article

    http://en.Wikipedia.org/wiki/Database_design

    Their link Web site contains some very questionable tips (physically do not delete) as good advice (do not tables).
    If you take its recommendations with a lot of coffee.

  • Standardization of FFT spectrum

    Dear Sir

    I take FFT of my real-time data that I collect current probe. I get the FFT spectrum successfully. But my supervisor asked me to normalize the present 25 Hz harmonic component in the FFT spectrum with fundamental component. Can you please guide me how to do this task.

    Also, what is the standards and what are its advantages.

    The frequency of the fundamental component is 50 Hz.

    Your attention and consideration will be highly appreciated.

  • Help of standardization

    -Very well, so I volunteer in a main recreation center and I'm supposed to do technical support with the instructors. We have 9 computers with the same hardware, and all the standard running xp.

    Teachers want to make sure that whenever a computer is turned off and turned back on all is given to a certain level, and I say everything from the number of icons in the status bar to size windows and the order of the icons in the start menu. It is because some students have never used computers before and panic if they see something on their screen is different from the person next to them as 'why his thing have 5 things on it and just mine a 3?' or ' why don't my icons appears as big as hers.

    So my question is should I buy some sort of server software? or is there something I can put in windows to achieve? If there is a software I have a name as well?

    Sorry if this isn't the right place to ask this type of question, I couldn't find a section for this

  • you have to turn the standardization IDS engine.

    Hi all.

    I would like to know how can stop us cisco ids engine nomalization? Is this a complicated or not?

    We have a problem when we allow the engine to nomalization of cisco on the ID which is inline mode. part of the asymmetric traffic will be dropped.

    So we'll disable cisco nomalization, now.

    Please give us advice for us.

    Thank you.

    Hi Syjeon,

    You can set the mode of standard-setter for the virtual sensor in question 'Protection of Mode' asymmetric to relax the TCP normalization if the sensor is the asymmetric traffic inspection:

    http://www.Cisco.com/en/us/docs/security/IPS/7.0/Configuration/Guide/CLI/cli_virtual_sensors.html#wp1034136

    You'll want to change the "'-TCP-escape-protection-mode inline" option "strict" to "asymmetric" to each of the virtual sensors see asymmetric traffic. "
