Technology Questions

1. Based on the lock-size given while creating the table space

2. Programer can direct the DB2 what lock-size to use

3. If lock - size ANY is specified, DB2 usually chooses a lock-size of PAGE

The standard query operators implement the IEnumerable<T> or the IQueryable<T> interface in C# and the IEnumerable(Of T) or the IQueryable(Of T) interface in Visual Basic.

The app delegate object is created by UIApplicationMain function at app launch time. The app delegate object's main job is to handle state transitions within the app.

In WF 4.0, the following two types of workflows are used:

 
     Flowchart workflows - Helps you to create workflows using the common flowchart elements. In WF, the Flowchart activity is generally used to implement a non-sequential workflow, and occasionally it implements sequential workflows in case the FlowDecision nodes are not used. The Flowchart activity contains a collection of flow nodes, which inherit from the FlowNode class. The following types of nodes or elements can be a part of a flowchart:
                 => FlowStep - Executes activities of a flowchart in a sequence.
                 => FlowDecision - Shows the execution on the basis of a Boolean condition.   It is similar to the If construct.
                 => FlowSwitch - Shows the execution on the basis of an exclusive switch. It is similar to the Switch construct.


      Procedural workflows - Helps you to create workflows using basic and sequential execution standards. In WF, procedural workflows use flow control constructs, such as While, Switch, ForEach, and If, to execute activities. These flow control constructs are similar to those found in procedural languages. Procedural workflows can also contain other flow control activities, such as Flowchart and Sequence.

Retain -Specifies that retain should be invoked on the object upon assignment. takes ownership of an object

Assign - Specifies that the setter uses simple assignment. Uses on attribute of scalar type like float,int.

An XSL sheet or a document may have duplicate elements and attributes. Therefore, the XML namespaces define a way to distinguish between duplicate element types and attribute names.

An XML namespace is a collection of element type and attribute names. It is a URI due to which any element type or attribute name in an XML namespace can be uniquely identified. 

It consists of two parts : the name of the XML namespace and the local name.

e.g.: xmlns: h=”https://www.abc.com”

After this, you can write

<h:table>

……..

</h:table>

to associate the table with the declared namespace. 

The window.history object can be written without the window prefix.
To protect the privacy of the users, there are limitations to how JavaScript can access this object.
Some methods:

    history.back() - same as clicking back in the browser
