yeah i prob did.Please notice that the creator of the Crossover have good marketing and ignore...Have feedback or suggestions about Amazon.ClickFox is the pioneer in Customer Behavior Intelligence.What do you mean by 'Customer Behavior Intelligence' (CBI)?Customer Behavior Intelligence is the ability to define, measure and analyze actual customer behavior in aggregate within a system in the context of the enterprise's business objectives.This vision enables companies to confidently align their goals with the needs and desires of their customers.Once the model is built, the customer data (gathered from call logs, Web logs or other user records) is mapped to the model, graphically presenting what's actually happening in these systems.Most of the current CRM analytical tools provide the capability to slice and dice customer and transactional data.The resulting intelligence enables the enterprise to articulate a business objective, see how that objective is manifested in the interactive system (Web, IVR, etc.These callers were either hanging up or pressing zero for an agent.The online bill pay function on a ClickFox client's Web site was achieving increased user traffic each month, but a large number of users were leaving the site at the authentication step.CRM system to monitor and improve its ability to inform, educate and serve the doctors who currently prescribe or may prescribe their drugs.Also healthcare, insurance and travel organizations have the volume and complexity of data that greatly benefit by understanding their customers' behavior.What vertical areas are you focusing on in the future and why?ClickFox can help them direct their customers to the desired service channel.If live agents can spend just a few more minutes a day on strategic activities, such as describing new services or resolving complex customer service issues, rather than reciting account balances or other information that should be provided in an automated way, the benefit to the bottom line is very real.It enables enterprises to quantify and measure strategic business objectives for real bottom line impact.Speech Technology Media, a division of Information Today, Inc.SEM (Search) Journal

Virtualization.Tal Cohen is a consultant specializing in J2EE and related technologies.Until
recently, he had worked as a researcher in IBM's Haifa Research Labs.We are also seeking online advertising sales representatives with proven track record.Owning Class Controls the Means of Production.Possible implementations in other
languages are discussed as well.These services are what is known as creation procedures in some languages and constructors in others.The polymorphic nature of classes is advertised as means for separating interface from
implementation.Then, the fact that there was a change must be advertised to the clients that wish to enjoy
its benefits.More concretely, we describe the design and implementation of an extension to the Java programming language to support factories.Using this terminology, Sections 3 and 4 expand on the motivation, by highlighting certain
limitations of constructors.This section also shows how factories support
many classical design patterns.We distinguish five, not entirely orthogonal, dimensions of class analysis: commonality,
encapsulation, morphability, binding, and purpose.This dimension makes the distinction between common elements of
the class notion (e.SmallTalk) and particular such
elements (e.More precisely, an element is common
if its incarnation in different instances of the class is identical; otherwise, it is particular.Also, common elements cannot access particular elements.Java's four, are orthogonal
to commonality.In other words, morphability pertains to the kind of changes
that a subclass may apply to components of the base class in the course of inheritance.There is a great variety in the morphability capabilities in different programming
languages.The analysis of this variety in full is beyond
the scope of this paper.Of course, this distinction can be made
only for class elements which can be replaced or altered in a subclass.C++ are famous for being statically bound.Specifically, we find that common elements are often statically bound.But, unlike the software components of the seventies, classes are instantiable.The mold is the memory layout which
instances of this class follow.It consists solely of field definitions.The mill is the set of
constructor bodies.To understand these terms better, consider class Vector from the standard Java library.The forge, type and mold of java.Vector(Collection), a variant that specifies the initial capacity (Vector(int)),
and a variant that specifies both the initial capacity and the capacity growth increment (Vector(int, int)).Vector includes methods and fields inherited
from three superclasses.These may be thought of as the class protocol.The mold for creating new objects is defined by the collection of all fields in this class
and all of its supertypes.Finally, the implementation is the body of the methods defined by the class or any of
its superclasses, while the mill is the body of the constructors defined in this class.Factories, the language extension proposed in this paper, are methods which return new
class instances.In analyzing constructors (in, e.In contrast, in EIFFEL the syntax is !!This anomaly raises the dilemma of method binding inside constructor bodies.Neither approach is without fault.The type definition of a subclass is
an extension of the type definition of the superclass.If a class C' inherits from C, then C' should be always substitutable for C.C++ is not much better: The C++ equivalent of Fig.Also, C++ would produce a runtime error if announce() is made abstract in class Baby.Interwoven initialization and setup in JAVA constructors.These three steps correspond exactly to steps C1, C2 and C4 in the effects of a creation instruction !!In Eiffel, it is the assignment of standard default values to
fields.As the example shows, however, initialization with default values is insufficient.Developers should be able to initialize all fields, across all levels of inheritance (i.We argue that good design of elaborate software systems often requires intervention in
the creation step.Factory, Factory Method, Singleton, and Object Pool,which address
precisely this need.As a result, if a
class evolves during development so that the new version employs (e.Creational patterns often collide with inheritance.The alternative of defining the constructor as protected, is problematic in Java, since
such constructors are visible to all classes in the same package.This happens because getInstance is technically part of the
type, while conceptually being part of the forge.This factory is invoked whenever the
Figure 5.Examining the factory body we see that
it always returns the same instance of the class.In the specific case of the SINGLETON design pattern, clients can compare
instances to realize that only one exists.Then, a factory of C can return an instance of C'.STemplate() in the example) would recurse infinitely.Such a call does not create an instance, nor does it return a value, and it must
appear only as the very first step in the constructor body.STemplate class, the value is cached to a static field, which is then returned.While there are many different solutions to the specific issue of singletons, (e.Thus, the problem of C'.In contrast, when factories are employed, the expression new C() can yield an instance
of C', since a subclass is always substitutable for its superclass.Factories also allow developers to separate the initialization and setup stages of object
construction.The implementation in the figure adheres to the simple rule that field are initialized in
constructors, and other setup is carried out by the factory.In particular the announcement
of the birth is made in the factory of NamedBaby (line 20).Such hidden constructors can only be invoked from the factory of a class,
regardless of their access level.Let us now deal with the dual situation, i.AGFa that the compiler (internally) injects into the class.Recall that in plain JAVA, instances of abstract classes cannot be created, even though
such classes have constructors.However, by the AGFa rule, abstract classes in plain JAVA do not have factories.As we shall see later, the internal
implementation of the widget factory class itself can also be improved with factories.DirectoryEntry, whose factory makes it possible to obtain an instance of either of
two implementing classes, Folder and File, depending on the parameter value.An interface with a factory.Interfaces with factories can eliminate this coupling.In the case of the List interface,
clients can generate instances of some default implementation by writing (say) new List().The factory can choose the proper concrete implementation, possibly based
on hints provided by the client.One possible factory for the List interface.Consider the learning effort of a
user in search of a specific service in a software library.Then, before m can be invoked, the user must
search for all the different implementation of I, say classes C1,C2,C3, .I'', then, the user must further search for
implementations C''1,C''2,C''3, .Providers in the Java standard library
taking a Map as a parameter.Interfaces (and abstract classes) with
factories can therefore simplify the adoption of new, unfamiliar classes.Line 2 in the figure starts the definition of a factory.The semantics is that the definition overloads
new when used for creating Account objects from within class Bank.Motif, may write import
static MotifWidgetFactory.This may be changed later to import static PMWidgetFactory.But there may be many such statements, in many source files.This will direct all widget factory calls to PMWidgetFactory.These are defined, as the name suggests, without the static keyword.It is not a coincidence that this looks very much like the Java syntax for creating an
instance of a dynamic inner class: c.But while nested inheritance has many distinct advantages with regard
to code modularity and the creation of extensible software systems, it only solves the need for factory methods for classes defined inside the same module as their client.For example, the factory for Accounts in class Bank (Fig.The addition of factories to interfaces is less straightforward, since interfaces in Java cannot contain any concrete methods.One possible solution is to introduce a new
keyword, such as factory, to the language.The second obstacle is due to C++ value semantics.The compiler must know the
space requirements of class instances allocated e.C++ or Java, creation procedures in Eiffel are named.We propose to the integration of factories into Eiffel by introducing a new part
to the Eiffel class declaration, alongside features, creates, etc.ANY) may be changed to a factory by any class that so desires.S_TEMPLATE) to obtain the shared instance.Since a class may include both creation procedures and factories, each with distinct
names, there is no risk of undesired recursion.Such methods are sometimes called factory methods.The Cecil language, specification and rationale.University of Washington, Seattle, 1993.Eiffel Analysis, Design, and Programming
