For settings, under private browsing, what is the difference between enbling and disabling cookies, aren't they going to be deleted anyway?

under private browsing, browsing history, cookies and etc will be deleted after private browsing is over.
however, for settings of privacy we can set private browsing as default. there are still some options below that we can choose to accept cookies from sites. does it make any sense? cookies are going to be deleted anyway after private browsing is over.
can anyone expain this to me?
appreciate it!

Cookies in Private Browsing work just like in normal mode, so you can still set allow and block exceptions for domains and disable third-party cookies.<br />
Only cookies aren't saved to disk in cookies.sqlite and they expire if you end the Private Browsing session, so all cookies are effectively session cookies.

What is the difference between subroutine and function module?

What is the difference between subroutine and function module?

Hi,
they can both return values.
FMs are mainly used when a routine is to be performed by many programs.
Subroutines (forms) are generally only executed within one program.
You can perform routines from other programs, but it's not often done.
both forms and FMs are reusable modularization units.
To distinguish we generally say that forms are used for internal modularization and
FMs are used for external modularization.
To decide on which to implement, consider whether you need the content to be used just for a limited program
or wheteher it can be called from many independent programs.
For the first purpose it is better to implement a form whereas for the second we implement an FM.
However, ABAP does not isolate the usage context.
That is; you can call a form from another program within whose code the form is not actually implemented.
However, this requires attention since the form may utilize global variables.
The same issue holds for FMs.
FMs are encapsulated in function groups and function groups may have global variables that can be globally
used by all FMs inside it.
Thanks,

What is the difference between Structure and Work area

Hi Guys,
What is the difference between Structure and work area?
Are they same with different names?
Thanks,
mini.

hey buddies,*
i had this same doubt for a long time and i have my finds with me ie wa and structure are the same but wa can hold a single record but structure cannot hold data in it but according to the previous posts folks say structure too holds data as wa does but i guess when debugging wa holds data and structure doesnt hold bcoz i tried.
types : begin of str_mara,
             matnr type mara-matnr,
            ernam type mara-ernam,
            end of str_mara.
data it_mara type table of str_mara.
select matnr ernam from mara into it_mara where matnr = '100-101'.
*********************if folks say wa = structure,this should work,isn't it?*********************************
loop at it_mara into str_mara.
write:/ str_mara-matnr , str_mara-ernam.
endloop.
*******************but it throws an error saying that str_mara is not a wa*******************************
i may not be correct too plz let me know if i'm wrong

What is the difference between Firefox and Firefox os please. I have a Samsung galaxy s3 mini what one would you recommend would be better for my phone

What is the difference between Firefox and Firefox os, and what one is better for the Samsung galaxy s3 mini, Please could you recommend which one is the best and most suitable for my phone please. Many thanks Michelle Petch

Thank you for your question.
Firefox is basically a browser.And Firefox OS is an Operating System.You can install Firefox in your SGS3 just like an android application.But if you want Firefox operating system on it. then you have to flash the ported Firefox OS on your device. Then it will be a completely different standalone operating system.you cannot install android applications on it.
To read more technical difference read:
Firefox OS:

Hope this clears your query.Thank you

Could you please explain me,
What's the difference between OEM and standart licensing of VMware vSphere for users?

The difference is usually the support you get. With OEM versions you'll often get support from the OEM and not from VMware directly.

iPad apps are designed specifically for the iPad and will not run on the iPhone or iPod Touch. iPhone/iPod apps will run on the iPad, but will only take up an iPhone sized portion of the iPad screen (though you get a 2x button which effectively doubles each pixel in both directions so may appear pixelated). There are also 'universal' apps (which have a '+' symbol against them in the store) which have processing in them to recognise the device that they are on and will tailor the display accordingly (so will make use of the iPad's larger screen).

Looking for new laptop what are the differences between pro and air? Besides size. Does the air preform like the pro?

Looking for new laptop what are the differences between pro and air? Besides size. Does the air preform like the pro?

The NEW macbook Pro and Air are EXTREMELY close in form factor
The newest macbook Pro is essentially a larger macbook Air with Retina display and options for speed in increasing prices up to an independent graphics and quad core processor.
both Air and new Pro now have PCIe SSD and permanent RAM.
The Air is the lightweight portable form factor, fast to boot and shut down, but with longer battery life than any of the macbook pro in 13"
Now the new macbook Pro and macbook Air are extremely close in form factor and nature.
both have 802ac wifi
both have permanent RAM, no superdrive
both are slim profiles and SSD
The only real differences now are (in the most expensive Pros) faster processors and quadcore processors and top end model autonomous graphics.
....and of course the retina display
both are now "very good for travel"
Other than features the form factor of the Air and Pro are VERY close now,....so now its merely a matter of features and price more than anything.
You need an external HD regardless of what you get for backups etc. Drop into an Apple store and handle both and make your choice based on features, such as Retina or non-retina, .... both at a distance now look like the same computer.
The Pro weighs more, ....but nowhere near what it used to just a month ago on the older macbook Pros
The NEW macbook Pro is a different creature entirely than the older macbook Pro, .....the new Pro is thicker than the Air, but id frankly call the NEWEST Pro a "macbook Air with Retina display" , or
Maybe a “macbook Air PRO with Retina display”
Instead of Air VS Pro now,.....its really a smooth transition from Air to pro without comparing say, 2 different creatures, now its like contrasting a horse from a race horse.
Either one in 8gig of RAM (preferably)... the 4gig upgrade costs very little, the I7 you will notice only 15% faster on heavy applications over the I5, and NOTHING on most APPS.....I5 has longer battery life.
As you see below, the non-Retina 13" AIR is 82% of the Macbook with Retina display in resolution
there is no magical number of pixels per inch that automatically equates to Retina quality.
http://www.cultofmac.com/168509/why-you-might-be-disappointed-by-the-resolution- of-those-new-retina-display-macs-feature/
A huge internal SSD isnt a game changer for anything, you need an external HD anyway
what you WONT READ on Apple.com etc. is that the larger SSD are MUCH FASTER due to SSD density
"The 512GB Samsung SSD found in our 13-inch model offers roughly a 400MB/s increase in write speeds over the 128GB SanDisk/Marvell SSD"

What's the Difference Between OLAP and OLTP?

HI,
What's the difference between OLAP and OLTP ? and which one is Best?
-Arun.M.D

Hi,
The big difference when designing for OLAP versus OLTP is rooted in the basics of how the tables are going to be used. I'll discuss OLTP versus OLAP in context to the design of dimensional data warehouses. However, keep in mind there are more architectural components that make up a mature, best practices data warehouse than just the dimensional data warehouse.
Corporate Information Factory, 2nd Edition by W. H. Inmon, Claudia Imhoff, Ryan Sousa
Building the Data Warehouse, 2nd Edition by W. H. Inmon
With OLTP, the tables are designed to facilitate fast inserting, updating and deleting rows of information with each logical unit of work. The database design is highly normalized. Usually and at least to 3NF. Each logical unit of work in an online application will have a relatively small scope with regard to the number of tables that are referenced and/or updated. Also the online application itself handles the majority of the work for joining data to facilitate the screen functions. This means the user doesn't have to worry about traversing across large data relationship paths. A heavy dose of lookup/reference tables and much focus on referential integrity between foreign keys. The physical design of the database needs to take into considerations the need for inserting rows when deciding on physical space settings. A good book for getting a solid base understanding of modeling for OLTP is The Data Modeling Handbook: A Best-Practice Approach to Building Quality Data Models by Michael C. Reingruber, William W. Gregory.
Example: Let's say we have a purchase oder management system. We need to be able to take orders for our customers, and we need to be able to sell many items on each order. We need to capture the store that sold the item, the customer that bought the item (and where we need to ship things and where to bill) and we need to make sure that we pull from the valid store_items to get the correct item number, description and price. Our OLTP data model will contain a CUSTOMER_MASTER, A CUSTOMER_ADDRESS_MASTER, A STORE_MASTER, AN ITEM_MASTER, AN ITEM_PRICE_MASTER, A PURCHASE_ORDER_MASTER AND A PURCHASE_ORDER_LINE_ITEM table. Then we might have a series of M:M relationships for example. An ITEM might have a different price for specific time periods for specific stores.
With OLAP, the tables are designed to facilitate easy access to information. Today's OLAP tools make the job of developing a query very easy. However, you still want to minimize the extensiveness of the relational model in an OLAP application. Users don't have the wills and means to learn how to work through a complex maze of table relationships. So you'll design your tables with a high degree of denormalization. The most prevalent design scheme for OLAP is the Star-Schema, popularized by Ralph Kimball. The star schema has a FACT table that contains the elements of data that are used arithmatically (counting, summing, averaging, etc.) The FACT Table is surrounded by lookup tables called Dimensions. Each Dimension table provides a reference to those things that you want to analyze by. A good book to understand how to design OLAP solutions is The Data Warehouse Toolkit: Practical Techniques for Building Dimensional Data Warehouses by Ralph Kimball.
Example: let's say we want to see some key measures about purchases. We want to know how many items and the sales amount that are purchased by what kind of customer across which stores. The FACT table will contain a column for Qty-purchased and Purchase Amount. The DIMENSION tables will include the ITEM_DESC (contains the item_id & Description), the CUSTOMER_TYPE, the STORE (Store_id & store name), and TIME (contains calendar information such as the date, the month_end_date, quarter_end_date, day_of_week, etc).

What is the difference between reset and adobe reset??

what is the difference between reset and adobe reset??

Reset and Reset (Adobe) will have the same effect unless you have changed the defaults.
For raw files LR uses its own defaults as the starting point for developing an image. For example, if you don’t apply your own import preset the standard default settings under detail are:
Sharpening:
Amount 25
Radius 1.0
Detail 25
Masking 0
Some users like to adjust these and make the tweaked settings into their own defaults. After making the desired adjustments in Develop simply hold down Alt and the reset button changes to Set Default.
Clicking the button will save the new default settings. This can be useful if you have more than one camera and wish to use different defaults for each.
To get back to the standard defaults simply hold down shift and click Reset (Adobe)
Restore
You can also restore the default settings globally in the develop module from the top menu:
Develop >> Set Default Settings
Then click the button "Restore Adobe Default Settings"
The standard defaults will then apply again to all future imports. For photos already in the catlaog where a non-standard default has already been applied you would need to adjust them manually using Shift+Reset (Adobe) but after adjusting one, it is then possible to sync all the others.

What is the difference between ws_upload and gui_upload

what is the difference between ws_upload and gui_upload
what is the difference between ws_download and gui_down load
pls tell briefly

Hi Kuamr,
UPLOAD and DOWNLOAD, the function modules used until now are not part of the standard set of ABAP commands. They are used to display the file interface on the presentation server. UPLOAD and DOWNLOAD are not compatible with USs and have been replaced by GUI_UPLOAD and GUI_DOWNLOAD.
The new function modules, GUI_UPLOAD and GUI_DOWNLOAD, have an interface that also allows you to write Unicode format to the local hard drive. For a description of these interfaces, refer to the documentation for each function module, available under SAP Easy Access " Development " Function Builder " Goto " Documentation.
Instead of using the function modules, you can use the static methods GUI_UPLOAD and GUI_DOWNLOAD of the global class CL_GUI_FRONTEND_SERVICES.
Hope this resolves your query.
Reward all the helpful answers.
Regards

What's the difference between setFollowRedirect() and setinstanceFollowRedi

What's the difference between setFollowRedirect() and setInstanceFollowRedirect() ?????

Hi there,
setFollowRedirects and setInstanceFollowRedirects both set flags that indicate whether or not the HtppURLConnection should follow a redirect if it receives one from the server that it is connecting to. The difference is that setFollowRedirects() is a static method that changes the behaviour for all instances of the HttpURLConnection class (or more likely the implementation class, HttpURLConnection is abstract) and setInstanceFollowRedirects() just changes it for the instance on which you call it.
BTW: The field set by setFollowRedirects is private (followRedirects) while the flag set by setInstanceFollowDirects is protected and is listed in the API docs (instanceFollowRedirects)
Hope this helps

What are the differences between Logos and LogosXT?

What are the differences between Logos and LogosXT?

Logos XT is a networking middle-layer maintained by the LabVIEW Network Technologies and Security group. Logos XT provides a thin layer on top of TCP/IP to simplify some common network tasks.
The underlying foundation for NI networking is called Logos.
I believe that the basic idea is Logos is what is going on behind the scenes at the base level and Logos XT lets you build your own networking protocols on top of Logos. Logos XT would be used if you want to make your own networking protocol instead of using TCP/IP or UDP.

What are the differences between tracing and hierarchical profiler?

There are many terms used by people, I am just wondering what are the differences between tracing and hierarchical profiler? Aren't they the same thing?
Thanks a lot.

Instrumentation and tracing are two different things; in fact they belong to two different categories - one's a thing the other's an activity.
Tracing is following the execution path of a program. Tracing shows us the the calls a program makes, perhaps the internal choices it makes (ifs and whiles), exceptions thrown, etc,
Instrumentation is code we build into our program to produce a record of its status. There are different techniques, from using DBMS_APPLICATION_INFO calls to monitor status to writing log tables or files. Instrumentation can be used to generate a trace; it can do profiling; it can provide information reports on outputs and exceptions.
In my opinion DBMS_TRACE and DBMS_HPROF are not instrumentation, because they are external to the program under investigation, rather than built into it. However, there is an obvious overlap between the insight they provide and what we might do with our own logging.
Cheers, APC

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 view and materialized views

Hi
What is the difference between view and materialized view ? can we update the base table using views

can we update the base table using viewsYes:
VIEWS
1. an updatable view is one that lets you perform DML on the underlying table
(see Oracle Database Concepts 10g - 5 Schema Objects)
2. non-updatable view requires INSTEAD OF Triggers
(see Oracle Database Concepts 10g - 22 Triggers)
SNAPSHOTS
You can have updateable (and writeable) snapshots - in updateable (writeable) MV replication.
Oracle uses snapshots (Materialized Views - MV) for two different purposes:
1. replication
2. automated Query Rewrite facility (first introduced in Oracle Discoverer, later included in Oracle database 8i).
Replication types in Oracle are:
a) Basic replication (MV replication)
- transaction based
- row-level
- asynchronous from master table to MV (Materialized View)
- DML replication only
- database 7 / 8.0 / 8i / 9i / 10g
- Standard and Enterprise Edition
1. Read-only MV replication
2. Updateable MV replication:
2.1 asynchronous from MV to master
2.2 synchronous from MV to master
3. Writeable MV replication
b) Multimaster replication
- transaction based
- row-level or procedural
- asynchronous or synchronous
- DML and DDL replication
- database 7 / 8.0 / 8i / 9i / 10g
- Enterprise Edition only
1. row-level asynchronous replication
2. row-level synchronous replication
3. procedural asynchronous replication
4. procedural synchronous replication
c) Streams replication
- (redo) log based
- row-level
- asynchronous
- DML and DDL replication
- database 9i / 10g (10g has Down Streams Capture)
- Enterprise Edition only (Standard Edition 10g can execute Apply process)
