Dfv1 Lesson 3

Front 1

<system.serviceModel> element

Back 1

An element located near the bottom of the web.config file which holds the specifications for all your hosted services

Front 2

App_WebReferences folder

Back 2

A Web services folder that contains files with the extensions wsdl, xsd, disco, and discomap and that define the references to the Web services that Web applications use

Front 3

DataReader

Back 3

An object that provides the properties and methods that enable the Web developer to retrieve data from a database on the server

Front 4

DataSet

Back 4

An object that provides the properties and methods that enable the Web developer to retrieve dta from a database on the server and which can also be used to change the database

Front 5

DTD

Back 5

Short for Document Type Definition, it's one of several ways an XML and XHTML document structure can be defined with rules

Front 6

schema

Back 6

The format of an object or database

Front 7

Web Service

Back 7

An application programming interface (API) that allows service-oriented applications to access Web-based service providers

Front 8

Windows Communication Foundation (WCF)

Back 8

Used in ASP.NET to easily create and consume web services

Front 9

XML

Back 9

Used to simplify data storage, transport data between systems having incompatable formats, separate data from HTML, save configuration settings, define XHTML, and so on.

Front 10

XML Validation

Back 10

A program that uses rules to make sure no mistakes were made in creating the XML file

Front 11

What is the PRIMARY purpose of XML?

To provide the additional syntax rules for XHTML

To transfer data between Web server and database

To improve the functionality of Web pages

To structure hierarchical data

Back 11

To structure hierarchical data

Front 12

What informs us of a broken DTD rule in a web page?

Any browser

A schema Validator

IntelliSense

All of the above

Back 12

IntelliSense

Front 13

How does the Schema compare to the DTD?

The Schema is more powerful than a DTD

The Schema is simpler than a DTD

Both use XML syntax to record the rules

Both are used to validate XHMLT documents

Back 13

The Schema is more powerful than a DTD

Front 14

What is NOT true about the Primary key of a database table?

A table is unable to store data without the primary key

It is one of the many available database constraints

It essentially "names" each row in the table

It must be unique and not NULL

Back 14

A table is unable to store data without the primary key

Front 15

How does the DataReader object compare to the DataSet object?

The DataReader reads all the data with a single method, while the DataSet reads a single row at a time as it moves forward

The DataReader is more powerful but reads more slowly than that DataSet

The DataSet uses the DataAdapter and the DataReader does not

The DataSet uses SQL to retrieve data, while the DataReader reads it directly without the need for SQL

Back 15

The DataSet uses the DataAdapter and the DataReader does not

Front 16

How is a DataSet object used to change the source data?

It uses the SQL method

It uses the Update method of the DataAdapter Object

It uses SQL through the Command object

It automatically changes the source as changes are made in the object

Back 16

It uses the Update method of the DataAdapter Object

Front 17

What is the primary purpose of the DataAdapter object?

To fill the DataSet with data

To connect the DataReader to the database

To adapt our controls to a variety of databases

To adapt our data into a format that will fit into a DataSet

Back 17

To fill the DataSet with data

Front 18

What is a valid advantage or disadvantage to using Visual Web Developer to create a WCF service?

Visual Web Developer is the only way to create a WCF service

It creates more efficient code than could be created with a text editor

It is easier to create a WCF service with Visual Web Developer than with a text editor

It is easier to create a WCF service with a text editor thatn with Visual Web Developer

Back 18

It is easier to create a WCF service with Visual Web Developer than with a text editor

Front 19

What is NOT true about App_WebReferrences?

It is a default directory for a WCF service

It keeps the Web site from having to look for some needed files

It is just one of many App_ directories

It must always be available to ASP.NET

Back 19

It must always be available to ASP.NET

Front 20

Which element is a grandchild of one of the 3 child elements of the <system.serviceModel> element of the web.config file

Back 23

XHTML or SGML

Front 24

The ___ validator not only defines the structure of an XML document, it defines the content and attribute values

Back 24

schema

Front 25

Both the DataSet and DataReader objects require the ___ object to make the connection to the datasource

Back 25

Connection or SqlConnection

Front 26

The DataReader object can use the SqlCommand object to send the SQL statement while the DataSet would use the ___

Back 26
