Question 1

The creation and management of user interfaces and database connectivity are not affected by the Web's existence.

Accepted Answer

The existence of the Web has greatly impacted the creation and management of user interfaces and database connectivity. With the emergence of web development technologies, user interfaces have become more dynamic, responsive, and interactive, and database connectivity has become more seamless and integrated with web applications. Web development frameworks such as React, Angular, and Vue.js have revolutionized the way user interfaces are created and managed, while APIs and web services have simplified the way web applications connect to databases and other external services.

Question 2

APIs are implemented as dynamic-link libraries that are dynamically invoked when needed.

Accepted Answer

True

Question 3

The Web server is the main hub through which all Internet services are accessed.

Accepted Answer

True

Question 4

When an end user uses a Web browser to dynamically query a database,the client browser actually requests a Web page.

Accepted Answer

When an end user uses a Web browser to dynamically query a database, the client browser sends a request for a Web page containing the query form or interface. Once the user submits the query, the server generates a response that includes the database results, which the client browser then displays on a new Web page or updates the current page dynamically.

Question 5

Usually,the native database connectivity interface provided by the vendor is not the only way to connect to a database;most current DBMS products support other database connectivity standards,the most common being ODBC.

Accepted Answer

Many current DBMS products support other database connectivity standards, including ODBC, in addition to their native database connectivity interface.

Question 6

Extending the Web server functionality implies that the Web server and the Web-to-database middleware will properly communicate with each other.

Accepted Answer

Extending the Web server functionality often involves adding new features or applications that require interaction with a database. Therefore, the Web server and the middleware for database connectivity must be able to communicate effectively to ensure the proper functioning of the extended system.

Question 7

The browser's interpretation and presentation capabilities are sufficient to develop Web-based applications.

Accepted Answer

Browsers require additional technologies like HTML, CSS, and JavaScript to develop and present web-based applications effectively.

Question 8

Java applications are compiled and stored in the Web browser.

Accepted Answer

Java applications are compiled into bytecode and stored in .class files. These .class files are then executed by the Java Virtual Machine (JVM), which interprets the bytecode and runs the program. Java applets used to be able to run within a web browser, but support for Java applets has been discontinued in most modern web browsers.

Question 9

The effects of bad database design,implementation,and management are multiplied in an environment in which transactions may be measured in hundreds of thousands per day,rather than in hundreds per day.

Accepted Answer

This statement is true because in high transactional environments, even small inefficiencies or errors in database design, implementation, and management can quickly multiply and result in significant issues for the organization. This can include slow performance, data inconsistencies, and even system crashes, which can have a major impact on the business operations. Therefore, it is essential to have efficient and effective database management processes in place to ensure the smooth functioning of high-volume transactional systems.

Question 10

The Web has helped create a new information dissemination standard.

Accepted Answer

The Web has enabled the sharing and dissemination of vast amounts of information in a way that was not previously possible. This has created a new standard for how information is accessed and shared.

Question 11

Whether you purchase online or by standing in line,the system-level transaction details are essentially the same and they require the same basic database structures and relationships.

Accepted Answer

The system-level transaction details for online and in-person purchases both require the same basic database structures and relationships to accurately record and store the transaction data.

Question 12

An API (application programming interface)is defined as a set of routines,protocols,and tools for building software applications.

Accepted Answer

The definition provided is accurate and describes what an API is.

Question 13

An API uses script files that perform specific functions on the client's parameters that are passed to the Web server.

Accepted Answer

The answer of An API uses script files that perform...

Question 14

Many organizations rely on their IS departments to create universal data access architectures based on Internet standards.

Accepted Answer

Many organizations consider their IS departments the primary source for developing a data access architecture that complies with Internet standards.

Question 15

Database connectivity software is also known as database middleware because it interfaces between the application program and the database.

Accepted Answer

Database connectivity software acts as a middleware between the application program and the database, providing a layer of abstraction and facilitating communication between them.

Question 16

A database server-side extension is known as Web-to-database middleware.

Accepted Answer

A database server-side extension is a type of middleware that allows web applications to communicate with databases. It provides a layer of abstraction between the application and the database, making it easier to develop and maintain web applications.

Question 17

The CGI is a newer Web-server interface standard that is much more efficient and faster than a dynamic link library (DLL).

Accepted Answer

The statement is incorrect. CGI stands for Common Gateway Interface and is not a newer standard compared to DLL. It was first introduced in 1993, while DLLs have been used since the early versions of Windows operating system. Additionally, the efficiency and speed of CGI vs DLL can depend on the specific application and its implementation.

Question 18

A client-side extension is a program that interacts directly with the Web server to handle specific types of requests.

Accepted Answer

A client-side extension is a program that runs on the client's device and interacts with the user's browser to modify or enhance its behavior, not with the Web server directly.

Question 19

Most database professionals do not consider the DBMS connection to the Internet to be a critical element in IS development.

Accepted Answer

The DBMS connection to the Internet is a critical element in IS development as it directly impacts the security and accessibility of the database. Without proper security measures, the database can be vulnerable to hacking and data breaches, resulting in significant losses for the organization. Therefore, it is essential to ensure a secure and reliable connection between the DBMS and the Internet.

Question 20

A good API makes it easy to develop a program by providing all of the building blocks.

Accepted Answer

A good API provides a set of clear, understandable methods for accessing a system's functionality, making it easier to develop an application by providing the necessary building blocks.
