Force.com PaaS provides the building blocks necessary to build any kind of business application, and automatically deploy them as a service to small teams or entire enterprises. The Force.com platform gives customers the ability to run multiple applications within the same Salesforce.com instance, allowing all of a company s Salesforce.com applications to share a common security model, data model, and user interface. The multitenant Force.com platform encompasses a complete feature set for the creation of business applications such as an on-demand operating system, the ability to create any database on demand, a workflow engine for managing collaboration between users,

The principal feature of these procedures is the periodic issuing of Status Enquiry messages from the user and the required Status Message Response from the network (Figure 8.6). (Note that since frame relay began, these messages have been referred to as Local Management Interface (LMI). This term is still used, although Local In-Channel Signaling is the term now used in specifications.)

Alternatively light can be described as a wave. In the wonderful world of , communications, it makes more sense to describe data transmission in terms of waves rather than individual particles, because nobody talks about the transmission of information over a wire circuit as a flow of electrons. Instead, we discuss how electromagnetic waves are modulated to convey information. As we proceed through this book, we can describe and discuss the flow of light through a fiber conductor without having to refer to the particle nature of light. Thus, in the remainder of this book we will describe and discuss light primarily in terms of an electromagnetic wave. An electromagnetic wave can be considered as a continuum of oscillating electric and magnetic fields moving in a straight line at a constant velocity. For light, that velocity is approximately 186,000 miles per second (mi/s), or in the metric [Syst me International (SI)] system of measureelectron detector electron

treated somewhat similarly to freely rotating dipoles, with an added complication that electron cloud fluctuations are much faster than molecular rotation. The energy associated with dispersion forces varies as the 6th power of the reciprocal of the distance, 1/r 6, so it is a relatively short-distance interaction.

To get started, you must first download the Google App Engine development kit, located at http://code.google.com/appengine/downloads.html. The SDK is available for Windows, Mac OS X, and Linux environments that also have Python 2.5. The SDK includes a web server application that simulates the App Engine environment. It also includes a local version of datastore, Google Accounts, and the ability to get URLs and send email from your computer using the App Engine APIs.

Data Modeling 1. Entity Type Rule: Each entity type (except subtypes) b e c o m e s a table. The primary key o f the entity type (if not weak) b e c o m e s the primary key o f the table. The attributes o f the entity type b e c o m e columns in the table. This rule should be used first before the relationship rules. 2. 1-M Relationship Rule: Each 1-M relationship b e c o m e s a foreign k e y in the table corresponding to the child entity type (the entity type near the Crow's Foot symbol). If the m i n i m u m cardinality o n the parent side o f the relationship is one, the foreign key cannot accept null values. 3. M - N Relationship Rule: Each M - N relationship b e c o m e s a separate table. The primary key o f the table is a combined key consisting o f the primary keys o f the entity types participating in the M - N relationship. 4. Identification Dependency Rule: Each identifying relationship (denoted by a solid relationship line) adds a component to a primary key. The primary key o f the table corresponding to the weak entity consists o f (i) the underlined local key (if any) in the weak entity and (ii) the primary key(s) o f the entity type(s) connected by identifying relationship(s). To understand these rules, y o u can apply them to some o f the E R D s used in 5. U s i n g Rules 1 and 2, y o u can convert Figure 6.14 into the CREATE T A B L E statements shown in Figure 6.15. Rule 1 is applied to convert the Course and Offering entity types

Helps to differentiate melanocytic from nonmelanocytic skin lesions Helps to differentiate benign from malignant skin lesions With dermoscopy the diagnostician s sensitivity to diagnose melanoma is 90% compared to 74% when the technique is not used Dermoscopy improves the diagnosis of melanoma by 16% The number of benign lesions excised for each melanoma found (malignant/benign ratio) is significantly decreased with dermoscopy Increases the diagnosis of early melanoma Increases the diagnosis of melanoma incognito (false negative melanoma)
