Advantage and disadvantage of view over physical table

Hi,
Can you explain me Advantage and disadvantage of view over physical table

Hi Nitin,
A view can be thought of as either a virtual table or a stored query. The data accessible through a view is not stored in the database as a distinct object. What is stored in the database is a SELECT statement. The result set of the SELECT statement forms
the virtual table returned by the view. A user can use this virtual table by referencing the view name in Transact-SQL statements the same way a table is referenced.
For more information about the advantages and disadvantages of views in SQL Server, please refer to the following two articles:

    Hi!
    Can any one explain about advantages and disadvantages of SOAP over HTTP.
    Thanks
    Sreenath

    Hi,
    Yes you can use RMI to communicate to your soa suite server allthough i could not get it to work from weblogic 10.3, there is a conflict with certain other libraries. From any other 10.1.3 oracle application server there should not be any problem. The biggest advantage of RMI over SOAP is performance. The soap client also generates lots of logging which can not be disabled, ... i already logged a bug on that. The advantage of SOAP over RMI is its underlying HTTP protocol which is, in some cases, the only protocol allowed by network engineers to pass through firewalls.

  • Advantages and Disadvantages of  Applet over JSP/servlet

    Can some one please let me know what are the major advantages and disadvantages of using Applets over JSP/Servlet technology?

    Well, a servlet / jsp is generated on the server, an applet on the client side. That's the most important difference.
    Appelt's usually are for little applications like games and stuff, you can run in a browser.
    Servlets are for dynamic pages, for example database-viewing and stuf...

  • Advantages and Disadvantages of XML over CSV

    Hi friends,
    We have a requirement in our implimentation project. We are implimenting HR module. The company is using SABA for Education and Certification.
    We are implimenting Education and certification in BW and the data for BW will be comming from SABA.
    We had a discussion on thursday about the integration of SABA to BW. We can do it through DBconnect or by using XI and for this there is time and cost involved.
    The techical team has come with some idea where there will give the data in the form of XML or in CSV format.
    I would like to know the advantages and disadvantages of each and also please consider the performance point in view.
    I would also like to know about the things that need to be  considered if we process the data in multiple files.
    Please give me inputs and the answers will be appreciated with valuable points.
    Regards
    Raghav Reddy

    Hi,
    my advice is to go for CSV anytime compared to XML.
    XML is first made available to the BW system via  SOAP ( Simple Object Acess protocol) interface. Next it is updated into the required data targets as before , Via a data source for the myself source system.
    SOAP = XML+HTTP.
    XML cannot be used for mass data. It is only to load small data into SAP BW on a single document level.
    BW provides flat file interface so, there is no all these hassles in case of CSV. go for CSV

  • Advantage and disadvantages of XI

    Dear All,
                 I was asked to list down the Advantages and Disadvantages of XI over other middleware tools in an interview
    Please advice.
    Regards,
    Ashish

    Hi Ashish,
    Advantages of XI:
    XI is a middleware like many others. It is well suited for connecting SAP systems with each other and with non-SAP.If your focus is not on SAP systems, other solutions might be a better choice today. SAP XI provides an integrated workflow engine that allows to define adapters to non-XML-protocols and mappings to convert data content from source to target.
    Any fully mature middleware should provide these three layers.
    1. An independent Message Queue
    2. A data consolidator and mapping engine
    3. Workflow processor.
    XI is lacking full-fledged Message Queue compared to other established Middleware products.
    Currently, SAP XI does not have the features like IBM Websphere, Seeburger or TIBCO.
    SAP's next XI release might provide this missing piece and many more features which is due 2007 i guess.
    Here are the advantages of SAP XI from my point of view.There are lots of advantages but to list a few :
    Easy Integration with SAP products & components (RFC, IDOC, Proxy).
    Data security as expected from any SAP product.
    Standards based - XML, XSD, Xpath etc
    Ability to communicate with other messaging systems/products.
    Business Process Management
    Synchronous & Asynchronous communication possible.
    Complex processes for communication possible instead of only sending and receiving (business process management) (connect e.g. asynchronous and synchronous steps, define complex communication scenarios)
    Mapping etc possible to accomplish in Java. Platform independent Java components.
    Java & .Net support.
    Big range of adapters for different technologies / tools (SOAP, Mail, JDBC, CDIX...)available in standard or offered by other companies (EDI e.g. by Seeburger).
    Process functionalities inside XI to modify content in the communication channel on own defined rules fpr business purposes.
    Central monitoring for data communication for all your communication between different systems.
    And the marketing issue: SAP and its partners provide high volume of development capabilities to make XI always up-to-date for new requirements

  • What are advantage and disadvantage for Physical Standy and Logical Standby

    HI,
    What are advantage and disadvantage for Physical Standy and Logical Standby configuration?
    Thanks
    Ken

    Logical standby database
    The key advantage for logical standby databases is that they're opened read/write, even while they're in
    applied mode. That is, they can be used to generate reports and the like. It is indeed a fully functional
    database. Also, additional indexes, materialized views and so on can be created.
    However (this being a disadvantage) not all datatypes are supported.
    Oracle (or more exactly the log apply services) uses the primary database's redo log, transforms them into
    SQL statements and replays them on the logical standby database.
    Physical standby database
    A physical standby database is a byte for byte exact copy of the primary database. This also means that
    rowids stay the same in a physical standby database environment.
    Oracle (or more exactly the log apply services) uses the primary database's redo log to recover the
    physical database.
    A physical standby database might be opened read only; however, the received logs are in this case not
    applied. When the logs are applied, the database is not accessible (it is then in a managed recovery state).

  • Advantages and disadvantages of using views ???

    Hi
    What are the advantages and disadvantages of using views in ABAP porgramming ? 
    Thank You

    hi,
    Data about an application object is often distributed on several tables. By defining a view, you can define an application-dependent view that combines this data. The structure of such a view is defined by specifying the tables and fields used in the view. Fields that are not required can be hidden, thereby minimizing interfaces. A view can be used in ABAP programs for data selection.
    More complicated views can comprise several base tables, the individual tables being linked with a relational join operation. If we dont specify the key fields, it takes time to fetch teh results.

  • Advantages and Disadvantages of webdynpro JAVA over J2ee?

    Hi,
       Can anybody provide me the advantages and disadvantages of webdynpro java over the J2EE?
    Regards,
    Harish.

    Hi,
    Webdynpro is the SAP standard technology for developing business user intrefaces.
    Webdynpro is like the frame work which follows the MVC Design pattern.
    Webdynpro uses most of the UI developement as declarative approach , i.e. most of the code will generated by the framework. so it will reduce the developement efforts.
    Adaptive RFC model to connect with SAP systems.
    All these are advantages over than the J2ee.

  • Advantages and Disadvantages of JMS Queue over Fabric

    HI,
    I want to know both the advantages and disadvantages of using JMS queue over the default Fabric queue in B2B adapter.
    Is it ok if I configure all my inbound and outbound transactions across all the trading partners to communicate with their respective SOA composite via the default JMS Queues(B2B_IN_QUEUE and B2B_OUT_QUEUE)?
    Please advise.
    Thanks in advance.
    Regards,
    Monica

    Hi Monica,
    But the size of the payload which I am using is unpredictable, it can differ from 1 MB to 40MB in future.This is not a problem. B2B can handle MB's of file if server has enough resources.
    all other payloads greater than 3MB, it is getting faulted with the message:
    "SAX Exception in translator. SAX Exception raised while trying to SAX Parse InputStream . Please make sure that the xml data is valid."Please remember that when B2B will find a large payload then it will write the large payload into the "Large Payload Directory" (defined in Administration--> Configuration) and pass it's reference to the middleware. So at middleware, you will not receive the actual payload but you will receive it's reference. Using File adapter sync read option, you may read the large file from "Large Payload Directory" at SOA layer.
    If you are using PS5 (11.1.1.6) then you will see that for large payload, B2B passes the JMS header LARGE_PAYLOAD to the back-end so in your composite, you may build logic around this. If this header (LARGE_PAYLOAD) is not coming at SOA layer then payload will be available in the body and if it is populated then payload will be available in the "Large Payload Directory" and it's reference will be available in the message body.
