Development of three simple services (one WSDL and two Restful) based on service-oriented architecture

Expected results:

• one WSDL service: use Visual Studio to create a WCF service.
• two RESTful services: implement it using HTTP API or use third-party APIs.
• three simple web pages that allow testing these services by entering data and displaying results (text field for data input, service call button, and field for displaying results)
• a short documentation in English including a diagram that shows the overall system design, its layers, components, and relationships between services, as well as a table listing input and output data, and resources needed for implementation (e.g.: libraries used, APIs)

 WordCount (RESTful service)

• Description: Analyzes a large text file and returns the count of occurrences of each word in JSON format.
• Operation: string WordCount(file)
• Input data: Text file.
• Output data: JSON string with "word-count" pairs.
• Language: C#.
• Technology: use WCF with HTTP protocol for interaction (RESTful API) (MANDATORY REQUIREMENT)
• Requirements:
  • Implement a service that accepts a text file (or text string) as an input parameter.
  • The service must analyze the file and return the count of occurrences of each word in JSON format (word — count).
  • Input: text file or text string.
  • Output: JSON with "word-count" pairs.

Top10ContentWords (RESTful service)

• Description: Analyzes text or a web page and returns the 10 most frequently used content words.
• Operation: string[] Top10ContentWords(string url)
• Input data: URL of the web page or text file.
• Output data: Array of the 10 most frequently used words.
• Language: C#.
• Technology: use WCF, with HTTP protocol for interaction (RESTful API) (MANDATORY REQUIREMENT)
• Requirements:
  • The service accepts a URL or text string.
  • Returns the 10 most frequently used content words (excluding stop words and HTML tags) in descending order of frequency.
  • Input: URL of the web page or text string.
  • Output: array of 10 words in JSON format.

Solar Energy Service (WSDL service)

• Description: Returns the annual average solar intensity index for a given location.
• Operation: decimal SolarIntensity(decimal latitude, decimal longitude)
• Input data: Latitude and longitude.
• Output data: A number representing the annual solar radiation intensity.
• Language: C#.
• Technology: WCF (Windows Communication Foundation) with SOAP protocol defined by a WSDL file (MANDATORY REQUIREMENT)
• Requirements:
  • Implement a WCF service that accepts latitude and longitude as input parameters.
  • The service must return the annual average solar intensity index for the specified location.
  • For this, you need to either use existing solar intensity data APIs, for example: https://developers.google.com/maps/documentation/solar/overview
  • Use the standard SOAP protocol for data exchange.

What needs to be provided as a result:

You need to provide one zip archive that will contain several files and folders. Here is what should be included in the archive:

1. Requirements Document (Word)

• Description of the service-oriented system for each service in English.
• A diagram showing the overall system design (layers, components, and their relationships) for each of the 3 services.
• Service directory: a table listing services, input and output data, descriptions, and resources for implementation.

2. Visual Studio Solution (development environment)

Your solution in Visual Studio should contain:

• WCF services (WSDL and RESTful):
  • Projects for both types of services (WSDL and RESTful).
  • Implementation of the services you selected: WordCount, Top10ContentWords, Solar Energy Service.
• TryIt Pages:
  • For each service, there should be a page that allows testing it by entering input data and viewing results.
  • You can implement TryIt pages as a simple web application or separate pages for each service.
• Code files for each service should be well-structured and commented.

3. Consolidated project in a single folder

All Visual Studio Solution files must be gathered in one folder:

• If projects are stored in different directories, you need to combine them into one folder for submission in the archive.
• Check that all files are present and that the project can be run from any other computer.

4. README or additional instructions 

Instructions for running your project (for example, if a local server or additional components need to be set up), add to a README.txt or README.md file with these explanations.
