Expert Solution & Answer
Chapter 5.8, Problem 5.4ARQ
Explanation of Solution
A database contains all the necessary information that is required for processing the business.
- The database is not useful for the business user since the contents that are present in them are structured in an unorganized way.
- The data stored in the database is present in the raw form and hence database is not ideal for the users.
Four elements of database application:
The four elements of database applications that are listed below:
- Forms
- Reports
- Queries
- Application Programs.
Purpose of the elements of database application:
The purpose of the each element is described below:
Forms:
The data present in the database can be viewed, inserted, updated and deleted using the elements.
Let us consider the example:
- Consider the student mark that needs to updates in the database.
- The form can be used to enter the marks scored by the user and the mark entered by the user can be viewed by the user through forms.
- Consider the mark that is entered by the user needs to be corrected and it can be updated through forms.
- Any student record that is not required can be deleted through forms.
Reports:
The data that are stored in the database are represented in the structural format by performing sorting, grouping, filtering and through other data manipulation process.
Let us consider the example:
A student record whose score can be viewed from highest to lowest order by using the sorting operation.
Queries:
The data values can be retrieved based on the search made by the user.
Let us consider the example:
A student whose score is greater than “90” can be viewed using the query given by the user.
Application Programs:
Application programs are used to provide security to the data, maintaining the consistency of the data and to process special purpose.
Let us consider the example:
The student data can be corrected only by the teacher who enters it the data is secured in such a way no student cannot modify the data present in the database...

In the past, encryption and decryption were mostly done by substitution and permutation of letters in a text message. study those classic cryptographic schemes Then, develop an automatic cipher using Javascript The cipher should be able to perform the following tasks:
generate keys
encrypt a given plaintext message with a key selected from the list of keys generated
decrypt a given ciphertext message with a known cipher key

- Case Study Instructions: Offshore Wind Energy in the North Sea For this case study, students will analyze the institutional challenges and social rules surrounding offshore wind energy development in the Dutch North Sea, as explored in the case study from the textbook (pages 44-46). Additional resources in this week’s learning module will provide further perspectives on the impact of wind energy on different stakeholders. Students should refer to the syllabus for specific guidelines regarding length, format, and content requirements. Reflection Questions to Consider: What are the key institutional challenges in implementing offshore wind energy in the North Sea? How do formal and informal social rules shape the use of this shared space? What conflicts arise between different stakeholders (e.g., fishermen, naval transport, military, and wind energy developers)? How can policymakers balance economic, environmental, and social considerations when allocating space for wind energy?…arrow_forwardAlphabetic Telephone Number TranslatorMany companies use telephone numbers like 555-GET-FOOD so the number is easier for their customers to remember. On a standard telephone, the alphabetic letters are mapped to numbers in the following fashion: A, B, and C = 2 D, E, and F = 3 G, H, and I = 4 J, K, and L = 5 M, N, and O = 6 P, Q, R, and S = 7 T, U, and V = 8 W, X, Y, and Z = 9 Write a program that asks the user to enter a 10-character telephone number in the format XXX-XXX-XXXX. The application should display the telephone number with any alphabetic characters that appeared in the original translated to their numeric equivalent.
