What is the difference between Service and Component

What is the difference between Service and Component?

Generally, the implementation of a service will be comprised of many components, each of which will be comprised of many objects.
Services should correspond to cohesive collections of use cases (eg an online bank), components are at a finer granularity (eg a table of numbers).

  • What is the difference between Service Station and Tempro?

    Searched for information on this but haven't been able to find it:
    What is the difference between Service Station and Tempro?
    I have just run the Toshiba Upgrade Assistant and it has installed Service Station but Tempro is already installed and seems to do the same thing.
    Regards
    Bushy

    Hi
    Both tools are from Toshiba an notifies you about the new driver updates available on the Toshiba driver page.
    As far as I know Tempro is little bit older than the Service Station.
    Furthermore the Service Station seems to provide a little bit more options and features as Tempro tool.
    However, i recommend using only one Utility my favorite is Service Station

  • What's the difference between jsp and jsf?

    who can tell me what's the difference between jsp and jsf?
    I'm puzzled when I found some of the technology in jsp is so similar to the ones in jsp( javaserver page)

    Hi,
    Find the difference between JSP and JSF
    1. A developer has more control with JSP, but (should) get easier development with JSF
    2. Event handling is done differently in JSP (HTTP) and JSF (Java)
    3. The UI is designed differently (or should be at least) with JSP (markup) and JSF (components).
    4. The end product should also be defined differently - JSP page versus a JSF application.
    Is this the only thing that is need to make a decision for either or? Probably not. There are other pieces that need to be taken in account when deciding which technology to use - tools support, enough components, type of application etc.... At this point there are not enough JSF components (although there are some interesting projects underway - Ajaxfaces, Myfaces, ADF Faces, and WebChart 3d) and enterprise tools support is still limited to a few tools vendor. Looking at our ADF Faces components they are currently available as early access (not production) and demands for these components are stacking up, literally, outside my office doorstep. Although I would love to make them production - now! - it is not a viable solution since we are still checking features and fixing critical bugs.
    All this combined - not enough enterprise level components in production, lacking tools support etc... - leave customers in a vacuum where the decision is either to continue with JSP, since it is mature and has a wide developer base, or move forward with JSF not sure if the support, or the developers will be there. This is particularly sensitive to customers that need to get started now and be production by summer.
    If you are in this vacuum here are some key points promoting JSF:
    1. Fundamental unit is the Component
    2. Built in event and state management
    3. Component sets can be provided by any vendor
    4. Closer to ASP.Net or Swing development
    5. Choice of UI technology
    6. Scale up (rich clients)
    7. Scale down (mobile devices)
    8. Built into J2EE containers in J2EE 5.0 (tentative)

    HR deals with the INFOTYPES which are similar to Tables in General ABAP.
    There are different ways of fetching data from these infotypes.
    There are different areas in HR LIKE Personal Admn, Orgn Management, Benefits, Time amangement, Event Management, Payroll etc
    Infotypes for these areas are different from one another area.
    storing of records data in each type of area is different
    LDBS like PNP are used in HR programing.
    Instead of Select.. we use some ROUTINES and PROVIDE..ENDPROVIDE.. etc
    and in the case of Pay roll we use Clusters and we Import and Export them for data fetching.
    On the whole Normal ABAP is different from HR abap.

    Look at the below link
    And finally,
    Few notes are below:
    InfoSets in the HR Application
    You can use SAP Query in HR to report on HR data. Queries are maintained as described in Creating Queries. The special features of queries created for HR are described in Maintaining Queries in the Human Resources Application. The maintenance procedure for HR InfoSets differs from the described procedure inasmuch as HR data fields are grouped together in infotypes.
    InfoSet management in SAP Query is also used for InfoSet Query. For further information, see Functions for Managing InfoSets.
    If you want to create InfoSets for HR, you can use logical databases PNP, PNPCE, PAP, and PCH (see HR Logical Databases). The database you must use to create your InfoSet depends on the component in which the data you want to report on is stored.
    The reports you can execute using InfoSets based on logical databases PNP (or PNPCE) or PCH are similar, but differ in that they can select different objects. The following table describes the connection between the logical database, and the infotypes you can include in an InfoSet. It also provides you with one or two examples of reports that you can execute using the appropriate InfoSets.
    Logical database PNP/PNPCE* PCH PAP
    Selection of Persons Objects from Personnel Planning Applicants
    Infotypes that can be included in the InfoSet Infotypes for· Personnel Administration (0000-0999) · Time Management (2000-2999) · Payroll infotypes · Infotypes for Personnel Planning objects that can be related to persons If the object type is specified:· Infotypes for the object type · Infotypes for objects that can be related to the specified object typeIf the object type is not specified:· All infotypes · Infotypes for Recruitment (4000-4999)· Some infotypes for Personnel Administration (such as 0001 and 0002)
    · Customer infotypes
    Reporting examples · Selection of all persons who participated in a specific business event, output of prices for reserved business events · Selection of all persons assigned to a specific personnel area, output of qualifications held by these persons · Selection of all business events held in London in March, output of all persons who participated in these business events · Selection of all positions assigned to a specific organizational unit, output of all persons assigned to the positions · Selection of all applicants hired last year to work on special projects, output of addresses for the applicants selected
    Logical database PNPCE (PNP Concurrent Employment) functions just like logical database PNP. The procedure for creating InfoSets is also the same. It only becomes significant if you work with Concurrent Employment.
    Creating InfoSets
    The maintenance procedure for HR InfoSets differs from the procedure described so far in this section inasmuch as HR data fields are grouped together in infotypes. To set up an InfoSet for the HR application, proceed as follows:
    1. On the initial screen for maintaining InfoSets, enter a name for the InfoSet and choose Create.
    2. On the next screen, enter a name for the InfoSet and select one of the HR logical databases in accordance with your reporting requirements.
    Customer infotypes can be created on all HR logical databases. In each individual case, therefore, you must decide which database to select so that you can report on customer infotypes.
    This screen enables you to enter an authorization group. All of the queries that are subsequently created using this InfoSet can only be executed by persons who have this authorization group.
    3. Choose .
    This takes you to the Infotype Selection for InfoSet  screen. You now have the option of creating field groups and assigning fields as required for non-HR InfoSets. Field groups that correspond to infotypes and already contain fields, however, are always created for HR InfoSets. The field groups are displayed in an overview tree in the top right section of the screen.
    The infotypes that you included in the InfoSet are displayed in an overview tree on the left of the screen. The infotype fields that are already included in field groups are displayed in a different color, and the corresponding field group ID is displayed.
    In the standard system, a field group is created automatically for each infotype that you included in the InfoSet (a field group corresponds to an infotype).
    In the standard system, each field group contains the infotype-specific fields. To ensure that working with the InfoSet is as easy as possible, you are advised to restrict your use of fields in each field group to those you really require. This means you should remove fields that are not required.
    An infotype's fields must only be assigned to the pertinent field group. Make sure this assignment is correct. If the assignment is incorrect, the InfoSet could be rendered unusable.
    When an InfoSet is created, the following fields are transferred automatically to the first field group:
    § Logical database PNPCE or PNP Personnel number
    § Logical database PAP Applicant number
    § Logical database PCH Object ID, plan version, and object type
    6. Determine the fields that must be included in the field groups of your InfoSet. If you require further information, see Assigning Fields to a Field Group.
    If you want, you can change the default sequence of field groups and fields as required using Drag&Drop.
    7. To save the InfoSet, choose .
    8. To generate the InfoSet, choose .
    On the Change InfoSet (InfoSet name) screen, you can choose Edit ® Change infotype selection to add more infotypes to the InfoSet, or to remove infotypes from the InfoSet. Remember to regenerate the InfoSet afterwards.
    This screen also enables you to update InfoSets if, for example, the system contains new additional fields for specific key values. To do so, choose InfoSet ® Additional functions ® Update additional HR fields.
    9. Go back to the initial screen for InfoSet maintenance.
    10. Choose User group assignment.
    11. Select a user group, and save your entry.
    sample code
    START-OF-SELECTION.
    GET pernr.
    rp_provide_from_frst p0000 space pn-begda pn-endda.
    if pnp-sw-found EQ '1'.

  • Could any one tell me what is the difference between swfloader and module loader?

    Hi  All,
                          Could any one tell me what is the difference between SWFLoader and Module Loader in Flex3 in detail?

    Hi,
    ModuleLoader is a kind of strange API that is really just intended to look like SwfLoader for modules that contain a single visual component, and hides most of the module loading infrastructure, which is all about class factories.
    What I mean by "only loaded once" is that if you have several places in the code that call the ModuleManager.getModule("url").load() call, it will only ever get loaded over the wire and interpreted once, subsequent "loads" will just re-dispatch pseudo-load events to the new client.  In other words, the class factory is a singleton for a given url. Unloading is a totally different story.  As you note, not everything is truly unloadable, because there may be lots of references to stuff in
    the module that will keep it alive and un-GC'ed.
    I suggest playing with the low-level API so that you understand the backing implementation, and this should help you understand the limits of ModuleLoader.
    The main difference between modules and applications is that modules have lower overhead, and they only ever get loaded once, no matter how many times you load them. If you're using the ModuleLoader API, keep in mind that you're losing about half the functionality of the module system.  I will assume that you are, because otherwise it would be obvious where to expose methods.  You might want to play around with the lower level ModuleManager API just to get a hang of what's going on - ModuleLoader is a pretty thin veneer over the lower API.                
                    Basically, what you want to do is to have your module implement an interface, say IModuleWhatever.
    Also try and refer to this link which was previously discussed in this forum..

  • What is the difference between tkprof and explainplan

    Hi,
    what is the difference between tkprof and explainplan.

    Execution Plans and the EXPLAIN PLAN Statement
    Before the database server can execute a SQL statement, Oracle must first parse the statement and develop an execution plan. The execution plan is a task list of sorts that decomposes a potentially complex SQL operation into a series of basic data access operations. For example, a query against the dept table might have an execution plan that consists of an index lookup on the deptno index, followed by a table access by ROWID.
    The EXPLAIN PLAN statement allows you to submit a SQL statement to Oracle and have the database prepare the execution plan for the statement without actually executing it. The execution plan is made available to you in the form of rows inserted into a special table called a plan table. You may query the rows in the plan table using ordinary SELECT statements in order to see the steps of the execution plan for the statement you explained. You may keep multiple execution plans in the plan table by assigning each a unique statement_id. Or you may choose to delete the rows from the plan table after you are finished looking at the execution plan. You can also roll back an EXPLAIN PLAN statement in order to remove the execution plan from the plan table.
    The EXPLAIN PLAN statement runs very quickly, even if the statement being explained is a query that might run for hours. This is because the statement is simply parsed and its execution plan saved into the plan table. The actual statement is never executed by EXPLAIN PLAN. Along these same lines, if the statement being explained includes bind variables, the variables never need to actually be bound. The values that would be bound are not relevant since the statement is not actually executed.
    You don’t need any special system privileges in order to use the EXPLAIN PLAN statement. However, you do need to have INSERT privileges on the plan table, and you must have sufficient privileges to execute the statement you are trying to explain. The one difference is that in order to explain a statement that involves views, you must have privileges on all of the tables that make up the view. If you don’t, you’ll get an “ORA-01039: insufficient privileges on underlying objects of the view” error.
    The columns that make up the plan table are as follows:
    Name Null? Type
    STATEMENT_ID VARCHAR2(30)
    TIMESTAMP DATE
    REMARKS VARCHAR2(80)
    OPERATION VARCHAR2(30)
    OPTIONS VARCHAR2(30)
    OBJECT_NODE VARCHAR2(128)
    OBJECT_OWNER VARCHAR2(30)
    OBJECT_NAME VARCHAR2(30)
    OBJECT_INSTANCE NUMBER(38)
    OBJECT_TYPE VARCHAR2(30)
    OPTIMIZER VARCHAR2(255)
    SEARCH_COLUMNS NUMBER
    ID NUMBER(38)
    PARENT_ID NUMBER(38)
    POSITION NUMBER(38)
    COST NUMBER(38)
    CARDINALITY NUMBER(38)
    BYTES NUMBER(38)
    OTHER_TAG VARCHAR2(255)
    PARTITION_START VARCHAR2(255)
    PARTITION_STOP VARCHAR2(255)
    PARTITION_ID NUMBER(38)
    OTHER LONG
    DISTRIBUTION VARCHAR2(30)
    There are other ways to view execution plans besides issuing the EXPLAIN PLAN statement and querying the plan table. SQL*Plus can automatically display an execution plan after each statement is executed. Also, there are many GUI tools available that allow you to click on a SQL statement in the shared pool and view its execution plan. In addition, TKPROF can optionally include execution plans in its reports as well.
    Trace Files and the TKPROF Utility
    TKPROF is a utility that you invoke at the operating system level in order to analyze SQL trace files and generate reports that present the trace information in a readable form. Although the details of how you invoke TKPROF vary from one platform to the next, Oracle Corporation provides TKPROF with all releases of the database and the basic functionality is the same on all platforms.
    The term trace file may be a bit confusing. More recent releases of the database offer a product called Oracle Trace Collection Services. Also, Net8 is capable of generating trace files. SQL trace files are entirely different. SQL trace is a facility that you enable or disable for individual database sessions or for the entire instance as a whole. When SQL trace is enabled for a database session, the Oracle server process handling that session writes detailed information about all database calls and operations to a trace file. Special database events may be set in order to cause Oracle to write even more specific information—such as the values of bind variables—into the trace file.
    SQL trace files are text files that, strictly speaking, are human readable. However, they are extremely verbose, repetitive, and cryptic. For example, if an application opens a cursor and fetches 1000 rows from the cursor one row at a time, there will be over 1000 separate entries in the trace file.
    TKPROF is a program that you invoke at the operating system command prompt in order to reformat the trace file into a format that is much easier to comprehend. Each SQL statement is displayed in the report, along with counts of how many times it was parsed, executed, and fetched. CPU time, elapsed time, logical reads, physical reads, and rows processed are also reported, along with information about recursion level and misses in the library cache. TKPROF can also optionally include the execution plan for each SQL statement in the report, along with counts of how many rows were processed at each step of the execution plan.
    The SQL statements can be listed in a TKPROF report in the order of how much resource they used, if desired. Also, recursive SQL statements issued by the SYS user to manage the data dictionary can be included or excluded, and TKPROF can write SQL statements from the traced session into a spool file.
    How EXPLAIN PLAN and TKPROF Aid in the Application Tuning Process
    EXPLAIN PLAN and TKPROF are valuable tools in the tuning process. Tuning at the application level typically yields the most dramatic results, and these two tools can help with the tuning in many different ways.
    EXPLAIN PLAN and TKPROF allow you to proactively tune an application while it is in development. It is relatively easy to enable SQL trace, run an application in a test environment, run TKPROF on the trace file, and review the output to determine if application or schema changes are called for. EXPLAIN PLAN is handy for evaluating individual SQL statements.
    By reviewing execution plans, you can also validate the scalability of an application. If the database operations are dependent upon full table scans of tables that could grow quite large, then there may be scalability problems ahead. On the other hand, if large tables are accessed via selective indexes, then scalability may not be a problem.
    EXPLAIN PLAN and TKPROF may also be used in an existing production environment in order to zero in on resource intensive operations and get insights into how the code may be optimized. TKPROF can further be used to quantify the resources required by specific database operations or application functions.
    EXPLAIN PLAN is also handy for estimating resource requirements in advance. Suppose you have an ad hoc reporting request against a very large database. Running queries through EXPLAIN PLAN will let you determine in advance if the queries are feasible or if they will be resource intensive and will take unacceptably long to run.

  • What is the difference between IPortalComponentContext and ServletContext ?

    1) What is the difference between IPortalComponentContext and ServletContext  or PageContext?
    2) Both IPortalComponentContext and ServletContext are Same . If Both are Same Both Can be interchangeably Used?
    3) If Both IPortalComponentContext and ServletContext are not same ,what is the specific functionality of each. I mean when is the IPortalComponentContext used and when is ServletContext is used?
    4) can any please explain the difference and functionlity of each code snippet?
    Thanks and Regards
    Prasad.Y

    Hi Prasad,
    what both contexts have in common is, that the context gives access to some resources the container provides.
    Nothing else.
    The servlet context is rather an application context of any java webapp and exists once per vm, a PortalComponentContext exists for every component and represents a view of the context in which the runtime runs the component.
    To answer your questions shortly:

  • What is the difference between LayoutManager and LayoutManager2?

    Hello,
    Can I know "What is the difference between LayoutManager and LayoutManager2?" Why was LayoutManager2 created when there is LayoutManager which does the layout creation? Where can I use both of them, especially LayoutManger2?
    Thanks

    Did you read the API???
    Defines an interface for classes that know how to layout Containers based on a layout constraints objectFor example BorderLayout uses LayoutManager2, which allows your to position individual components using the known constraints:
    panel.add(Component, BorderLayout.NORTH);
    panel.add(Component, BorderLayout.SOUTH);
    Whereas, FlowLayout or GridLayout don't allow you to use constraints, components are displayed in the order they are added:
    panel.add(component1):
    panel.add(component2);
    You only care about this when you are writing your own LayoutManager.

  • What is the difference between #variable_name and :variable_name?

    Hi!
    What is the difference between #variable_name and :variable_name?
    I have found that if we use alphanumeric variable then :variable_name return value in quotes but #variable_name without quotes.
    Why it does not work in the same way for variable default values when variable is used in filter? (It works in mapping)
    I use variable in filter like T.OUT_DATE>convert(datetime,:LAST_UPDATE_DATE,121)
    When I use my variable in package and do refresh it works fine. But when I try to execute the same interface with variable default value I get error. Seems that variable name has been not changed to the value. It does not work with default value in quotes neither without quotes.
    Any ideas how to solve that?
    Thank you in advance!
    Edited by: user13278245 on Sep 15, 2010 4:34 AM

    Question is how to make it work with default value, when I execute interface standalone, not in package? And why it works in mapping but not in filter?
    + I have found that it works if source is Oracle. It doesn't work only for MS SQL source.

  • What is the difference between start() and run()

    Hi:
    what is the difference between start() and the run()???
    in my app, i have
    Console.debug( "starting thread to listen for clients" );
    _server = new Server( this );
    _server.start();
    _server extends Thread..
    why everytime i use server.start(); my app will terminate on it is own, even though in my servr.run() method, i have a while loop
    and if i call _server.run() explicitly in my code, that while loop will be in execution
    can someone let me know??
    thnx

    what is the difference between start() and the
    run()???start() is a method on Thread that tells it to start.
    run() is a method in the object that the thread executes.
    why everytime i use _server.start(); my app will
    terminate on it is own, Err.... I'm not convinced this is true. It'll throw an IllegalThreadStateException, if you try to restart an existing thread.
    If that's what you're saying.
    even though in my _servr.run()
    method, i have a while loopI don't see the connection. Are you saying that the while loop never terminates, and you don't see why the thread is terminating?
    and if i call _server.run() explicitly in my code,
    that while loop will be in executionIf you call server.run() explicitly, then run() will be executed in the same thread that you called it in.

    SQL> select table_name from user_tables;
    TABLE_NAME
    BAR
    FOO
    2 rows selected.
    SQL> select table_name from user_tables where table_name in (select table_name from user_tables where table_name = 'FOO');
    TABLE_NAME
    FOO
    1 row selected.
    SQL> select table_name from user_tables where exists(select table_name from user_tables where table_name = 'FOO');
    TABLE_NAME
    BAR
    FOO
    2 rows selected.So, why is this? the WHERE EXISTS means 'if the next is true', much like where 1=1 being always true and 1=2 being always false. In this case, where exists could be TRUE or FALSE, depending on the subquery.
    WHERE EXISTS can be useful for something like testing if we have data, without actually having to return columns.
    So, if you want to see if an employee exists you might say
    SELECT 1 FROM DUAL WHERE EXISTS( select * from emp where empid = 10);
    If there is a row in emp for empid=10, then you get back 1 from dual;
    This is what I call an 'optimistic' lookup because the WHERE EXISTS ends as soon as there is a hit. It does not care how many - only that at least one exists. It is optimistic because it will continue processing the table lookup until either it hits or reaches the end of the table - for a non-indexed query.

    Rob Cole's ExifMeta plugin displays the Subject Distance field (and much more).  Unfortunately, his Web site appears to be down again.  He used to be very active here, but he hasn't posted in several months.

  • What's the difference between thunderbolt and mini displayport?

    I'm trying to connect my Macbook with a monitor and I'm thinking of what cable to get. I will have to connect using a (Thunderbolt to HDMI cable) or a (mini displayport to HDMI cable).
    I was wondering what's the difference between Thunderbolt and mini displayport
    Thanks

    @bontistic: it is not true that only the Macbook Air supports Thunderbolt. All models(!) support thunderbolt: also the Macbook Pro's and Mini's. Eg.: http://www.apple.com/nl/macbookpro/features.html#thunderbolt
    My Macbook Pro from 2011 already supported Thunderbolt...
