Differences between 16GB and 32GB Models

Hi,
I'm looking at the differences between the 16GB and 32GB Xperia Z tablets (model numbers SGP311GB and SGP312GB) and apart from the differences in memory (obviously ) there doesn't appear to be anything else.
So, this begs the question what benefit does the internal memory have over an SD card - if I wanted 32GB I could buy the 16GB model and put a 16GB SD card in cheaper than the £50 difference between the two models.
or, have I missed something less obvious.
Thanks

1. The Main function of an SD Card is for media data such as photos videos, music etc.
2. The Tablet Z supports microSD, microSDHC and microSDXC up to 64GB.
The FAT32 format will restict the size of files you can move to card.

Any difference between 16 and 32GB model other than capacity?

Hi,
I've just had my 16GB iPhone 4 stolen, and it's not looking like I'm going to be able to get it back. So I'm going to have to dig deep and buy a new one. But I'd want an upgrade at the same time, to allow me to better cope with the loss. So I'm thinking about the 32GB model (also, i was pushed for space with the 16GB).
Is there any difference; Battery life, weight, speed, etc between the 16 and 32GB models? Beyond the obvious larger capacity?
As most will know, bigger hard drives are faster, mainly due to higher areal density, but I don't know how/if this applies to solid state storage. I thought possibly it might use more battery life and be slightly faster.
Thanks.

No difference except for storage capacity.

Difference between table and table model

From what I've understood till now, in a JTable, the table itself is actually only a "display area" while the actual data is located in the table model. Is this correct?
Does this mean it is possible to delete rows and columns within the table itself without affecting the actual data in the table model?

Hi,
ok, I will try to answer your second question "is it possible to delete rows and columns in the table but not in the table model"?
The table - lets say the table's view - reflects the data of the data model only, if you fire the correct notification messages via the TableModelListener interface - JTable itself is a TableModelListener and updates its display accordingly to these messages - it never holds data by itself - if something is to be redrawn in the view, JTable ask the model via getValueAt(...) for the data and renders it using one of the cellrenderers delivered by the column of the column model resp. one of the registered default renderers.
Now to your question - you can't delete a row in the tables view, without any change in the table model, as so the data isn't hold by the table's view, it is only held by the table model. But the other way round, it is possible - often accidentially - you can change the data in the table model and forget to fire a notification message for it via the TableModelListener interface - in this case, JTable will not update its view - and the table may look strange, if parts of its view is hidden by other applications and afterwards redrawn, when this application closes. Only the parts, that were hidden, will be redrawn - and this is done with the new data. So, keep track of always sending the correct notification message with every change you make in the table model, so that JTable is able to keep its view up to date.
Hope this helps

Difference between N+1 HA model and traditional secondary/Tertiary Cisco 5508 Model.

Hi Team
we are going to implement N+1 HA cisco WLC high availability for that we have procured one WLC 5508.
However i am not able to find out difference between N+1 and secondary WLC configured under each AP in wireless tab ?
As per my understanding both are giving the same functionality. Can you please highlight any difference ?
Thanks....

Hi Scott
Thanks a lot for the information .This is very useful.However i need one small clarification..
There are three redundancy model..
1+1 where you need one WLC acts HA SKU
N+1 Where one WLC is backup for all N WLC
Third and last one is , where we mention the secondary and tertiary WLC under wireless tab.
So i want to know the difference between second and third option.
Thanks

Differences between operational systems data modeling and data warehouse da

Hello Everyone,
Can anybody help me understand the differences between operational systems data modeling and data warehouse data modeling>
Thanks

Hello A S!
What you mean is the difference between modelling after normal form like in operational systems (OLTP) e. g. 3NF and modelling a InfoCube in a data warehouse (OLAP)?
While in a OLTP you want to have data tables free of redundance and ready for transactions meaning writing and reading few records often, in an OLAP-system you need to read a lot of data for every query you do on a database. Often in an OLAP-system you aggregate these amounts of data.
Therefore you use another principle for these database scheme. This is called star schema. This means that you have one central table (called fact table) which holds the key figures and have keys to another tables with characteristics. These other tables are called dimension tables. They hold combinations of the characteristics. Normally you design it that your dimensions are small, so the access on the data is more efficent.
the star scheme in SAP BI is a little more complex than explained here but it follows the same concept.
Best regards,
Peter

Differences between Satellite A210-11c model PSAEGE and PSAFGE

Is there any difference between Satellite A210-11c model PSAEGE and Satellite A210-11c model PSAFGE? I have a PSAEGE model and I need the XP drivers. I found some helpful drivers for the PSAFGE model and I don't know if it's ok to install them.
Thanks a lot!

Can you please tell me where you have founded all those helpful drivers?
Sorry but according all possible documents I have found on the Internet Satellite A210-11C is definitely PSAEGE and I didnt found any with PSAFGE part number. Where you picked up this info?

Why is my SSD showing 250mb/s difference between read and write...

So i have recently upgraded to a SSD in my 2011 MBP. 2.4Ghz i5 16Gb RAM. I swapped my HDD with a Samsung 840 Series 250Gb SSD, I noticed a huge speed bump. See attached photos. Read is clocked at 503MB/s peak, and Write is clocked at 260MB/s peak on the SSD. My Question is why is there a 250MB/s difference between read and write?? Using Black Magic Disk Speed test. Mac OS X 10.8.4 Beta.
Thanks

Writes are performed very differently on SSD than they do on a hard drive, and it is common for SSDs to have lower write speeds than reads.
It's actually quite interesting if you're a geek: http://en.wikipedia.org/wiki/Write_amplification
As long as the speeds do match your manufacturer specification for the model (and they do: http://www.samsung.com/us/computer/memory-storage/MZ-7TD250BW ) , there is nothing to be concerned about.

HT5470 Difference between Nano 7th generation Models (Silver)

I want to know what is the difference between the Ipod Nano SIlver MD480E/A and MD480LL/A.
I've found those "models" in online stores offering Nano Silver 16GB with Bluetooth (7th generation)
Thanks.

iPod Nano 6th Gen has 8GB and 16GB versions ,but iPod Nano 7th Gen has just one 16GB version. And most difference between 6th and 7th Gen iPod Nano is their different body size and shape.

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...

Difference Between BAPI And RFC in ABAP

Hi,
i want to know difference between BAPI and RFC in SAP,
can we call SAP GUI screen from NON SAP System Using BAPI.
Reg,
Hariharan

Hi Ravishankar,
The difference is not importat while you understand the concept.
I think, RFC is the protocol for calling functions from external systems in R/3.
I understand like BAPI a series of complet functions that SAP offers you for use and model a business use.
But if I need program a function that can be called for external system i would call it RFC_NAME, because is a unique function that makes a single task.
In other words, the difference i think is about work idea more than another thing.
RFC
A remote function call is a call to a function module running in a system different from the caller's. The remote function can also be called from within the same system (as a remote call).
RFC consists of two interfaces : A calling interface for ABAP Programs and a calling interface for Non-SAP programs.
The RFC Interface takes care of :-
- Converting all parameter data to the representation needed in the remote system
Calling the communication routines needed to talk to the remote system.
Handling communications errors, and notifying the caller, if desired ( using EXCEPTIONS paramater of the CALL FUNCTION).
BAPI
BAPIs are standardized programming interfaces (methods) enabling external applications to access business processes and data in the R/3 System.
BAPIs provide stable and standardized methods to achieve seamless integration between the R/3 System and external applications, legacy systems and add-ons.
BAPIs are defined in the BOR(Business object repository) as methods of SAP business object types that carry out specific business functions.
BAPIs are implemented as RFC-enabled function modules and are created in the Function Builder of the ABAP Workbench.
The most critical difference btwn BAPI and FM is that BAPI can be wrapped in Business objects whereas RFC cant.
BAPI are RFC enabled function modules. the difference between RFc and BAPI are business objects. You create business objects and those are then registered in your BOR (Business Object Repository) which can be accessed outside the SAP system by using some other applications (Non-SAP) such as VB or JAVA. in this case u only specify the business object and its method from external system in BAPI there is no direct system call. while RFC are direct system call Some BAPIs provide basic functions and can be used for most SAP business object types. These BAPIs should be implemented the same for all business object types. Standardized BAPIs are easier to use and prevent users having to deal with a number of different BAPIs. Whenever possible, a standardized BAPI must be used in preference to an individual BAPI.
The following standardized BAPIs are provided:
Reading instances of SAP business objects
GetList ( ) With the BAPI GetList you can select a range of object key values, for example, company codes and material numbers.
The BAPI GetList() is a class method.
GetDetail() With the BAPI GetDetail() the details of an instance of a business object type are retrieved and returned to the calling program. The instance is identified via its key. The BAPI GetDetail() is an instance method. BAPIs that can create, change or delete instances of a business object type
The following BAPIs of the same object type have to be programmed so that they can be called several times within one transaction. For example, if, after sales order 1 has been created, a second sales order 2 is created in the same transaction, the second BAPI call must not affect the consistency of the sales order 2. After completing the transaction with a COMMIT WORK, both the orders are saved consistently in the database.
Create( ) and CreateFromData! ( )
The BAPIs Create() and CreateFromData() create an instance of an SAP business object type, for example, a purchase order. These BAPIs are class methods.
Change( )
The BAPI Change() changes an existing instance of an SAP business object type, for example, a purchase order. The BAPI Change () is an instance method.
Delete( ) and Undelete( ) The BAPI Delete() deletes an instance of an SAP business object type from the database or sets a deletion flag.
The BAPI Undelete() removes a deletion flag. These BAPIs are instance methods.
Cancel ( ) Unlike the BAPI Delete(), the BAPI Cancel() cancels an instance of a business object type. The instance to be cancelled remains in the database and an additional instance is created and this is the one that is actually canceled. The Cancel() BAPI is an instance method.
Add<subobject> ( ) and Remove<subobject> ( ) The BAPI Add<subobject> adds a subobject to an existing object inst! ance and the BAPI and Remove<subobject> removes a subobject from an object instance. These BAPIs are instance methods.

What is the difference between ERP2004 and SAP 47 Enterprise?

Currently we have SAP 47 Enterprise with WAS 6.2. I understand ERP2004 is NW and 6.4 sp9. Can any one please let me know the major difference between ERP2004 and SAP 4.7 Enterprise ( more from abap / workflow view)?
Thanks
Swamy

From Abap point of view some of the major add-on in erp2004,netwever :
1) Development of webdynpro studio for java development for portal and iviews.
2) Major abap development uses <b>Abap object oriented</b> methodology, rathet hten old conventional Abap,i.e MVC model (Model,View,Controller) where in it uses concept of classes,interfaces,etc.
3) Advanced BSP tech using MVC model to develop web based modules
4) It is closesly integrated with web-based CRM and BW/APO

What is the difference between Apple Ipad Air Model

What is the difference between Apple Ipad Air Model # MD788LL/A and Model # MD788LL/B

These models both use the same i7-3820QM processor, so difference(if any) is probably not in CPU(only stepping can be different, but intel site shows only E1). GPU is also the same(again, 'revision' or something may be different). doesn't seem that RAM is different either, it's 1600 DDR3L(only timings and power consumption can differ, but it's unlikely). SSD - cannot say anything from specs. Screen[manufacturer]? Googling shows nothing for me. And only visible difference(apart from model number) for me is price. As I'm considering purchase, I don't want to spend more money to get different number.

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).

Difference between idoc and rfc

what is the difference between idoc and rfc? when and where it is used? when there is idoc, why rfc vice versa?

IDoc (for intermediate document) is a standard data structure for electronic data interchange (EDI) between application programs written for the popular SAP business system or between an SAP application and an external program. IDocs serve as the vehicle for data transfer in SAP's Application Link Enabling (ALE) system.
IDocs are used for asynchronous transactions: Each IDoc generated exists as a self-contained text file that can then be transmitted to the requesting workstation without connecting to the central database.
Another SAP mechanism, the Business Application Programming Interface (BAPI) is used for synchronous transactions.
A large enterprise's networked computing environment is likely to connect many geographically distributed computers to the main database. These computers are likely to use different hardware and/or operating system platforms. An IDoc encapsulates data so that it can be exchanged between different systems without conversion from one format to another.
IDoc types define different categories of data, such as purchase orders or invoices, which may then be broken down into more specific categories called message types. Greater specificity means that an IDoc type is capable of storing only the data required for a particular transaction, which increases efficiency and decreases resource demands.
An IDoc can be generated at any point in a transaction process. For example, during a shipping transaction process, an IDoc may be generated that includes the data fields required to print a shipping manifest. After a user performs an SAP transaction, one or more IDocs are generated in the sending database and passed to the ALE communication layer. The communication
layer performs a Remote Function Call (RFC), using the port definition and RFC destination specified by the customer model.
The IDoc is transmitted to the receiver, which may be an R/3, R/2, or some external system
RFC
Remote Function Calls (RFC) and data exchange through IDoc message documents. RFC makes direct and synchronous calls of a program in the remote system. If the caller is an external program it will call an RFC-enabled function in R/3 and if the calling program is the R/3 system it will call an RFC-function in another R/3-system or it will call a non-R/3 program through a gateway-proxy (usually rfcexec.exe). BAPIs are a subset of the RFC-enabled function modules, especially designed as Application Programming Interface (API) to the SAP business object, or in other words: are function modules officially released by SAP to be called from external programs.
note:reward points if solution found helpfull.....

DIFFERENCE BETWEEN BAPI AND ALE

HI
COULD ANYBODY TEL ME
DIFFERENCE BETWEEN BAPI AND ALE

Hi Kalyan
ALE is a SAP specific method how to distribute data from and to SAP. It uses the asynchronous calls based on IDOC structures.
However in the distribution modell of ALE can also be used BAPIs. They will then automatically converted into IDOC structures. After creating the IDOCs they will be passed over to the receiver using the tRFC protocol.
Wheras the BAPIs are using the sRFC protocol.
