Tutorials for MVC, Data Controls, and Data Bindings

I am looking for some good tutorials on:
Model View Controller concept
Creating Data Controls from Java Beans
Creating and Using Data Bindings
We are using JDeveloper, but do not want to use ADF as we want more control than ADF offers.
Thanx
Pam

Just curious, what control do you need that ADF doesn't offer you?
If you use ADF, you don't have to use it for every page. You can bind some components on your page using adf directly to your adf data controls, and you can bind other components to your backing beans, and have full control. No reason to throw out adf if there are just a few cases where you need more control.
Btw, do you have a link to a page describing these non adf data controls and data bindings?

Selected node in a tree table (via Data Controls and not managed bean)

I am facing some problems in getting the selected row in a tree table.I have used data controls for creating the tree on the page.
I have 3 POJO's,ex; Class AB which has a list of Class CD.And Class CD has a list of class EF. (Used for the tree table)
Now i have a java class, called MyDelegate.java which has a list of AB.I generated data controls off this MyDelegate class and have dropped the ABlist as a tree table (also displaying CD and EF in the tree table).
It displays fine with nodes of AB,CD (child of AB)and EF(child of CD)
The tree table is not bound to any managed bean.
For performing actions on the tree, i create a method - "doSomething() in the delegate class",generate data controls and drop it as a button.
Inside doSomething(), i need acess to the selected node in the tree (it can be a node of type AB or CD or EF).
The problem: I always get access to the node of type AB, and not the child nodes no matter what i click in the tree table.
doSomething(){
DCBindingContainer dcBindingContainer = (DCBindingContainer)ADFUtil.evaluateEL("#{bindings}");
DCIteratorBinding dcTreeIteratorBinding = dcBindingContainer.findIteratorBinding("lstABIterator");
RowSetIterator rowTreeSetIterator = dcTreeIteratorBinding.getRowSetIterator();
DCDataRow rowTree = (DCDataRow)rowTreeSetIterator.getCurrentRow();
if (rowTree.getDataProvider() instanceof AB) {
          //do something
          AB selectedAB = (AB)row.getDataProvider();
} else if (rowTree.getDataProvider() instanceof CD){
          //do something
} else if (rowTree.getDataProvider() instanceof EF) {
          // do something
How do i access the "selected child node of the tree table" here in the delegate class method? Pls help.

Hi Frank,
Thanks for the response. In my case, i dont have a managed bean, so i am slightly unsure how to do it.
There is a mention "Note that another way to access the treeTable component at runtime is to search for it in JavaServer Faces UIViewRoot. This latter option allows you to write more generic code and does not require to create a page dependency to a managed bean"
How do i use this adf view root (without a managed bean) to get hold of the selected row in the tree table. Pls help.
Thanks.

Difference between data control and grid control

Hello, All:
When I installed my 10g database, the OEM data control was also installed, I can use it to manage my database perfectly. now I see there is a seperate product for OEM grid control that need to be installed from different CD, Can someone tell me what's the difference between this Data Control and Grid Control?
Thanks in advance

DBconrtrol is for monitor only one database but from Enter prise manager Grid Control you can monitor and manage all the database in your enterprise basically
Oracle Enterprise Manager Grid Control is a single, integrated product for monitoring and managing Oracle software infrastructure as well as applications and business services in diverse IT environments

The integrated packaged( ODi, data quality and data profiling) for HP-UX wount available till 10.1.3.5.0 which will be released by this year end.

I have had my Iphone 5s for 2 months and all the fotos and data (fotos and data were not backed up) that I had were erased after I restored it with my old Iphone 4s backup, can I get my unsaved fotos and data back? and if I can, how?

Validation For Date,String and Date in a reports Region

Apex 4
Good day to all apex users How do I validate a apex_item.text if the value is string the user can only input a string value if it is number then the user can input numbers only and if it is a date the user can only input a date values?

APEX_ITEMS are not part of the default apex gui... In fact they are just functions which returns html.
You can however do some stuff with the attributes parameters. You can find some cool stuff over here: Re: Validation For Date,String and Date in a reports Region
If you want apex validation you need to create a page validation and loop over your apex_items with apex_application.g_f0x

Oracle Data Profiling and Data Quality

Hi,
How to create metabase for Oracle Data Profiling and Data Quality.Is metabase and repository are same.

Hi,
You can create a metabase in the Metabase Manager:
- Expand Control Admin
- Click on Metabases
- in the Metabases window, right-click on the white area and select Add...
- go through the wizard to create your metabase
This is documented in the ODQ/ODP tutorial (http://www.oracle.com/technology/products/oracle-data-quality/pdf/oracledq_tutorial.pdf) and in the Documentation (in Metabase Manager or Oracle Data Quality go to Help and then Manuals).
Thanks,
Julien

Difference b/w DATA TYPE and DATA OBJECT & differences b/w TYPE and LIKE

hai
can any one say the differences between Data type and Data Object.
And also differences between TYPE and LIKE
thanks
Gani

hi,
_Data Types and Data Objects_
      Programs work with local program data that is, with byte sequences in the working memory. Byte sequences that belong together are called fields and are characterized by a length, an identity (name), and as a further attribute by a data type. All programming languages have a concept that describes how the contents of a field are interpreted according to the data type.
      In the ABAP type concept, fields are called data objects. Each data object is thus an instance of an abstract data type. There are separate name spaces for data objects and data types. This means that a name can be the name of a data object as well as the name of a data type simultaneously.
Data Types
   As well as occurring as attributes of a data object, data types can also be defined independently. You can then use them later on in conjunction with a data object. The definition of a user-defined data type is based on a set of predefined elementary data types. You can define data types either locally in the declaration part of a program using the TYPESstatement) or globally in the ABAP Dictionary. You can use your own data types to declare data objects or to check the types of parameters in generic operations.
     All programming languages distinguish between various types of data with various uses, such as .. type data for storing or displaying values and numerical data for calculations. The attributes in question are described using data types. You can define, for example, how data is stored in the repository, and how the ABAP statements work with the data.
Data types can be divided into elementary, reference, and complex types.
a. Elementary Types
These are data types of fixed or variable length that are not made up of other types.
The difference between variable length data types and fixed length data types is that the length and the memory space required by data objects of variable length data types can change dynamically during runtime, and that these data types cannot be defined irreversibly while the data object is being declared.
Predefined and User-Defined Elementary Data Types
You can also define your own elementary data types in ABAP using the TYPES statement. You base these on the predefined data types. This determines all of the technical attributes of the new data type. For example, you could define a data type P_2 with two decimal places, based on the predefined data type P. You could then use this new type in your data declarations.
b. Reference Types
Reference types are deep data types that describe reference variables, that is, data objects that contain references. A reference variable can be defined as a component of a complex data object such as a structure or internal table as well as a single field.
c. Complex Data Types
Complex data types are made up of other data types. A distinction is made here between structured types and table types.
Data Objects
      Data objects are the physical units with which ABAP statements work at runtime. The contents of a data object occupy memory space in the program. ABAP statements access these contents by addressing the name of the data object and interpret them according to the data type.. For example, statements can write the contents of data objects in lists or in the database, they can pass them to and receive them from routines, they can change them by assigning new values, and they can compare them in logical expressions.
       Each ABAP data object has a set of technical attributes, which are fully defined at all times when an ABAP program is running (field length, number of decimal places, and data type). You declare data objects either statically in the declaration part of an ABAP program (the most important statement for this is DATA), or dynamically at runtime (for example, when you call procedures). As well as fields in the memory area of the program, the program also treats literals like data objects.
        A data object is a part of the repository whose content can be addressed and interpreted by the program. All data objects must be declared in the ABAP program and are not persistent, meaning that they only exist while the program is being executed. Before you can process persistent data (such as data from a database table or from a sequential file), you must read it into data objects first. Conversely, if you want to retain the contents of a data object beyond the end of the program, you must save it in a persistent form.
Declaring Data Objects
      Apart from the interface parameters of procedures, you declare all of the data objects in an ABAP program or procedure in its declaration part. These declarative statements establish the data type of the object, along with any missing technical attributes. This takes place before the program is actually executed. The technical attributes can then be queried while the program is running.
     The interface parameters of procedures are generated as local data objects, but only when the procedure is actually called. You can define the technical attributes of the interface parameters in the procedure itself. If you do not, they adopt the attributes of the parameters from which they receive their values.
ABAP contains the following kinds of data objects:
a. Literals
Literals are not created by declarative statements. Instead, they exist in the program source code. Like all data objects, they have fixed technical attributes (field length, number of decimal places, data type), but no name. They are therefore referred to as unnamed data objects.
b. Named Data Objects
Data objects that have a name that you can use to address the ABAP program are known as named objects. These can be objects of various types, including text symbols, variables and constants.
Text symbols are pointers to texts in the text pool of the ABAP program. When the program starts, the corresponding data objects are generated from the texts stored in the text pool. They can be addressed using the name of the text symbol.
Variables are data objects whose contents can be changed using ABAP statements. You declare variables using the DATA, CLASS-DATA, STATICS, PARAMETERS, SELECT-OPTIONS, and RANGESstatements.
Constants are data objects whose contents cannot be changed. You declare constants using the CONSTANTSstatement.
c. Anonymous Data Objects
Data objects that cannot be addressed using a name are known as anonymous data objects. They are created using the CREATE DATAstatement and can be addressed using reference variables.
d. System-Defined Data Objects
System-defined data objects do not have to be declared explicitly - they are always available at runtime.
e. Interface Work Areas
Interface work areas are special variables that serve as interfaces between programs, screens, and logical databases. You declare interface work areas using the TABLES and NODESstatements.
What is the difference between Type and Like?
Answer1:
TYPE, you assign datatype directly to the data object while declaring.
LIKE,you assign the datatype of another object to the declaring data object. The datatype is referenced indirectly.
Answer2:
Type is a keyword used to refer to a data type whereas Like is a keyword used to copy the existing properties of already existing data object.
Answer3:
type refers the existing data type
like refers the existing data object
reward if useful
thanks and regards

ODI Data Profiling and Data Quality

Hi experts,
Searching about ODI features for data profiling and data quality I found (I think) many ... extensions? for the product, that confuse me. Cause I think there are at least three diferents ways to do data profiling and data quality:
In first place, I found that ODI has out of the box features for data profiling and data quality, but, acording to the paper, this features are too limited.
The second way I found was the product Oracle Data Profiling and Oracle Data Quality for Oracle Data Integrator 11gR1 (11.1.1.3.0) that is in the download page of ODI. Acording to the page, this product extends the existing inline Data Quality and Data profiling features of ODI.
Finally, the third way is Oracle Enterprise Data Quality that is another product that can be integrated to ODI.
I dont know if I understood good my alternatives. But, in fact, I need a general explanation of what ODI offer to do Data Quality and Data profiling. Can you help me to understand this?
Very thanks in advance.

Hi after 11.1.1.3 version of ODI release, oracle no longer supports ODP/ODQ which is a trillium software product and this not owned by oracle. Oracle is recommending the usage OEDQ for quality purposes. It's better if you could spend time on OEDQ rather than trying to learn and implement ODP/ODQ in ODI

Is there a way to manually custom-edit the "Date created" and "Date modified" attributes of files in Mac OS 10.6?

In "List View" in a Finder window, among the many column options are "Date created" and "Date modified." In "View Options" (command-J) for any folder, one can add these columns, along with the standard ones "Size," "Kind," "Label," etc.
A user can alter a file's name, and a file's "label" (i.e. its color). On the other hand, a user can NOT arbitrarily edit/alter a file's official "size" -- other than by physically altering the contents of the file itself, obviously.
But what about a file's "Date created" and "Date modified"? Can either of those be manually edited/changed, just as a file's name can be changed -- or is a file's creation-date an immutable attribute beyond the editorial reach of the user, just as a file's "size" is?
And yes, a person can "alter" a file's "Date modified" by simply modifying the file, which would change its "Date modified" to be the moment it was last altered (i.e. right now). But (and here's the key question) can a user somehow get inside a file's defining attributes and arbitrarily change a file's modification date to be at any desired point in the past that's AFTER its creation date and BEFORE the present moment? Or will so doing cause the operating system to blow a gasket?
If it is possible to arbitrarily manually alter a file's creation date or modification date, how would it be done (in 10.6)? And if it is NOT possible, then why not?

sanjempet --
Whew, that's a relief!
But as for your workaround solution: All it will achieve is altering the created and modified dates to RIGHT NOW. What I'm looking to do is to alter the modification/creation dates to some point in the past.
I'm not doing this for any nefarious reason. I just like to organize my work files chronologically according to when each project was initiated, but sometimes I forget to gather the disparate documents all into one folder right at the beginning, and as a result, sometimes after I finish a job, I will create a new folder to permanently house all the files in an old project, and when that folder is places in a bigger "completed projects" folder and then is organized by "Date created" or "Date modified" in list view, it is out-of-order chronologically because the creation and modification dates of that particular project folder reflect when the folder was created (i.e. today), and not when the files inside the folder were created (i.e. weeks or months ago).
The simplest solution would simply to be able to back-date the folder's creation or modification date to match the date that the project actually started!

Data Carriers and Data carrier type

Hi Sap Gurus,
Pls let me know is there any necesssity of defining any new Data Carrier types other than PC,
if so at what circumstances and requirements,
also pls throw some light about data Carriers, when is the new data carriers required to be created
at what circumstances and requirements.
is that to access a document from different server or Different system, if it is so why is this required as the documents are always stored in a central content server and Once checked in, any one can access the document from Server,
2) can we make use of Application softwares Installed in one System and make it run in another system, example,
if there are say 4 system totally, among this S1 system1 has Autocad Installed in it ,
rest of the 3 system have not installed Autocad, Can the system 2,3 and 4 edit the auto cad drawings in there system, does at this situations where Datacarries and Data carries types come in to picture,
Please throw some light on this
Thanks and regards
Sathish

Dear Christoph Hopf,
Thanks a lot for your Quick Response
as you have Explained,i assume it is mainly used to store a local copy or extra copy of the Original application files in the system which we use to View them, or if we feel to store the copy in any other system also.
Example Say there are 3 systems S1, S2 and S3
if we are viewing an original file in System S1 and want the same Copy to be stored in System S2 or S3.....
then this data carrier configuration is required if iam right?
But Sir apart from this funtionality can i also know the SAP definition purpose, as it defines data carrier type as below
The system requires the data carrier type in order to exchange data with other data carriers.
This is the case, for example, if the user:
wants to process original application files stored on another computer
wants to use an application installed on another computer
if i can interpret this in right way
it tells us that, by use of data carrier and Data carrier types
we can access a original file stored in Different systems,
if it is so why is this required as the documents are always stored in a central content server and Once checked in, any one can access the document from Server,
2) can we make use of Application softwares Installed in one System and make it run in another system, example,
if there are say 3 system totally, among this S1 system1 has Autocad Installed in it ,
rest of the 2 system have not installed Autocad, Can the system 2, and 3 edit the auto cad drawings in there system, does at this situations where Datacarries and Data carries types come in to picture,
if so how is this made possible?
pls explain with example or Screen shots in Wiki if possible
can u tell me what is the difference between Datacarrier and Datacarrier types with any examples as well
Thanks and regards

Calender using Date From and Date To

Hi,
I'm trying to build a calender based on a table that has a user_name, date_from, date_to and comments.
Basically I want the calender to show all the dates betwwen the date from and date to. Is there any way of getting the calender to use those dates and all the days in between or will I have a to build a view that returns one row for each day between the start and end
Whats the best way of doing this and does any one have an example
Thanks in advance

What is the purpose of Date From and Date To In Oracle HRMS ?

hi
I have doubt on
What is the purpose of Date From and Date To In Oracle HRMS?
Thanks

Where do you see these fields? Please give full details (eg, the navigation path).
If you're referring to Effective Start Date and Effective End Date (effective_start_date, effective_end_date) these are two fields that appear on many HRMS entities. They're used to store dated history over time. For example:
14-Jan-2009 to 19-Apr-2009 - Pam Stephens
20-Apr-2009 to date - Pam Erickson
In this example Pam got married on the 20th April 2009 and changed her surname from Stephens to Erickson. Here the history of changes are kept so that if we date-track to any time prior to the 20th April 2009 we'll see Pam Stephens and if we date-track on or after the 20th April 2009 we'll see Pam Erickson.
