PHP Date and Time

Using the sources provided you are to add functionality to search for all blogs written before a specific date. The framework for the assignment is set for you

      user.html                       Contains the HTML to prompt for a date

      blog_user.php               PHP code to parse the html form and call the function to search by date

     blog_db_interface.php  PHP code to perform the search

You will need to

      blog_user.php     

               Convert the date to a unix time stamp using strtotime()                         10 points

               Verify the strtotime return value. On error throw an exception              10 points

               Convert the unix time stamp to a date and time string using date()       10 points

               Verify the date functionality. On error throw an exception                      10points

               If all is OK then call the function to peform the search

     blog_db_interface.php

               Implement the SQL query to perform the search and display the results    

               Process errors from calling  “prepare”,  “execute” and “bind_results”

                            All errors should result in an exception thrown                                 10 points

               Search result should display “Blogger’s name”  “Blog Summary”                  10 points

What to turn in (as a single ZIP)

        Submit your modified source files: blog_user.php and  blog_db_interface.php       

Database Project

 Create a website for access your database, and include some functionalities, like:•insert records to each table,  you may need to update other tables when you need to insert a record to a table.•query records from each table using different columns•delete records from each table, you might need to update other tables when you delete a record from a table. 

Assignment

Answer the following questions with your own words.

  • What is the most important difference between generic software product development and custom software development? What might this mean in practice for users of generic software products?
  • What are the four important attributes that all professional software should possess? Suggest four other attributes that may sometimes be significant.
  • Apart from the challenges of heterogeneity, business and social change, and trust and secutiry, suggest other problems and chanllenges that software engineering is likely to face in the 21st century. (Hint: Think about the envorionment.)
  • Consider the integration and configuation process model shown in Figure 2.3. Explain why it is essential to repeat the requirements engineering activity in the process.
  • Suggest why it is important to make a distinction between developing the user requirements and developing system requirements in the requirements engineering process.
  • Explain why software testing should always be an incremental, staged activity. Are programmers the best people to test the programs that they have developed?

Java

Explain what is meant by the syntax and the semantics of a programming language. Give Java examples to illustrate the difference between a syntax error and a semantics error. Use different examples than those found in the textbook. 

Your Discussion should be at least 250 words in length, but not more than 750 words.

you are designing an application that will

  

you are designing an application that will help keep track of sales for your company. This sales data may be shared with potential clients. There are three types of accounts that track sales for your company: supplies, services, and paper. All sales accounts will have an account id. You will need attributes to keep track of the number of hours and rate per hour of services provided. You will need attributes to keep track of the number of pounds of paper sold and the price per pound. You should also keep track of the total sold in supplies. In addition to the following required attributes for supplies, services and paper account classes, feel free to include additional attributes that you think are appropriate. Your management wants the application to be easy to maintain and to promote code reuse as much as possible. You propose that this can be best achieved by utilizing object-oriented design principles and you want to incorporate an inheritance hierarchy with the account types. The first step of your design process is to design and present to the team an Account inheritance hierarchy. Create a class diagram for the Account inheritance hierarchy. Your subclasses should be Supplies, Services, and Paper. Explain your class diagram and answer the following: How does this inheritance hierarchy promote code reuse? How does this inheritance hierarchy make the application easier to maintain? If in the future, if another type of account is needed, what are the steps for adding this new account type to your design?

 
 

Using NetBeans/Java , implement your previous class diagram. Your application will use the Accounts inheritance hierarchy . There are three types of sales accounts that track sales for your company: supplies, services, and paper. Create a test class that tests each subclass’s constructor and display each instance created. Override the toString() method so that your object data is printed.

For now, include your pseudocode, UML class diagram and verbiage that explains your design

ERP system

 You work for a large financial institution. Discuss the importance of information governance and information security, from the perspective of your customers, and your employees. Should your large financial institution make its information governance and information security clear to its customers and why?

Moreover, The CEO feels that the capital investment into an Enterprise Resource Planning (ERP) system would be the best decision as part of the next strategic plan for the organization. Make a persuasive argument for ERP into the organization. What specifics, benefits, drawbacks, and changes will result from the implementation of ERP? Why would you disagree (if you are) with the CEO on the use of ERP?
