Cloud Computing Using Oracle Application Express

Chapter 1: Introduction to Cloud Computing and Application Project 1 The book focuses on developing business applications for the cloud and provides step by step guidance in developing a financial accounting system to give you a taste of cloud computing with respect to building business applications in Oracle APEX. This chapter provides an overview of cloud computing and the application project.   Chapter 2: Application Navigation 9 First of all, you will be guided through the creation of a navigation structure for the application including its menus, submenus, and a navigation bar. Using this structure, users can access different segments of the application according to their respective privileges, which is granted to them by the application administrator.   Chapter 3: Companies 13 The application is capable of maintaining accounts of multiple companies simultaneously. This setup allows you to create as many companies as you need. Each company is provided with a unique code that distinguishes its transactions from that of the others.   Chapter 4: Fiscal Year 15 Each company created in the application must have a fiscal year to keep records of its financial proceedings. You can create different fiscal years for different companies. However, this book follows a fiscal year which starts from 1st July and ends on 30th June.   Chapter 5: Voucher Types 25 You can create multiple voucher types to record financial transactions. This approach is handy to distinguish between transactions of various natures. For example, you can create two different voucher types to record payments made through cash and bank.   Chapter 6: Application Segments 29 You will create a robust security module for this application to control its access. The application consists of several segments that need protection from unauthorized access. In this chapter, you will spot all those segments which will be utilized in the next chapter to handle the application security.   Chapter 7: User Groups 35 Assigning application access privileges to individual users is not an easy task, especially when they are in large numbers and belong to different positions. To make things simple, you will create a few groups, each of which will be granted different application privileges. Then you will create individual user accounts and assign them a group. Using this approach the users inherit their privileges from the group they belong to.   Chapter 8: Create Users 43 In this chapter, you will create the application users. Each user is associated with a group and is assigned to a company. After making a successful log-in attempt, the application provides the users with the privileges of the group they belong to allowing them to maintain the accounts of the company assigned to them.   Chapter 9: Reset Password 47 The application stores encrypted password for each user. The interface created in this chapter will be used to set initial passwords for all application users. The same interface is provided to the users (with fewer privileges) so that they can change their own passwords when they want to.   Chapter 10: Switch Company, Year and Month 53 Different users in the application are granted different privileges. Some users are allowed to maintain accounts of multiple companies, while some are restricted to handle just one company. The former group of users can switch to other companies, years, and fiscal periods from this interface.   Chapter 11: Cost Centers 57 Cost-conscious organizations always keep both eyes on their expenses. With the help of a two-level cost center setup, you allow them to keep track of all costs incurred on different departments in different locations.   Chapter 12: Chart of Accounts 63 Financial accounting applications follow a pre-defined accounts list which is called the chart of account. It is created to maintain accounts in an organized manner. In this chapter you will create an interface where users will create a chart of account comprising four levels for each company.       Chapter 13: Copy Chart of Accounts 71 The Copy Chart of Accounts utility is provided to avoid the labor involved in creating a chart of account for each company individually. It will allow the application administrator to copy an existing (master) chart of accounts to all companies created in the application.   Chapter 14: Enter Vouchers 75 After completing the setup phase, you create an interface to record business transactions. This interface is called a Voucher, where you select a type, provide a number, select a date, enter a description, pick accounts and cost centers from their respective setups, and enter debit and credit figures. It is a real-time process. Once you save a voucher, all financial reports in the application are updated immediately.   Chapter 15: Search Transactions 85 It’s a routine work for an accountant to search for a transaction recorded in the past. In this chapter you will create a utility which searches transactions for a user-specified criterion.   Chapter 16: Vouchers Verification 89 This interface is created for authorized users to verify vouchers created by data entry clerks. Once a voucher is marked as verified, no one can manipulate it unless the authorized person reverses its state to unverified.   Chapter 17: Vouchers Report 95 In this edition the free JasperReports server will be used to produce hard copies of all reports. The server will be set up in this chapter. It is a usual accounting practice to print vouchers after creation. This chapter will teach you how to create parameterized group reports with custom layouts.   Chapter 18: Ledger Report 103 In this application you will create some generic financial reports. The ledger report is one of them which provide details of an account in a grid. To get this report, the user must provide a couple of parameters comprising account range and duration.   Chapter 19: Trial Balance Report 109 The trial balance report presents opening, activity, and closing balances of accounts in a grid. You can generate this report for a specific cost center and for a selected level.     Chapter 20: Opening Bank Transactions 117 You will next enable the accountant to reconcile his ledger transactions with his bank. This is the first step in the bank reconciliation process where the accountant records all bank transactions which remained un-reconciled prior to starting this application.   Chapter 21: Bank Reconciliation 121 This is the interface which you provide to the accountant for bank reconciliation. Besides the transactions entered through vouchers, this interface contains a region to display opening un-reconciled transactions, recorded in the previous chapter.   Chapter 22: Bank Reconciliation Report 127 After reconciling ledger transactions with the bank statement, the accountant generates this report which shows the remaining un-reconciled transactions and balances as per ledger and bank statement.     Chapter 23: Month Closure 131 In the application, the fiscal year of a company comprises twelve periods. All transactions are recorded in their respective periods. After recording all transactions in a period it can optionally be marked as closed to prevent data manipulation.   Chapter 24: Year End Processes 135 The year-end process comprises two options: Temporary and Permanent. The former process generates a new fiscal year and transfers closing balances of accounts to the new fiscal year. The permanent closing process marks a year as permanently closed. After executing the TYE process you can manipulate data in all open months of that year, whereas the PYE process doesn’t allow any kind of data manipulation.   Chapter 25: Budget Allocation 141 By allocating budgets for accounts an accountant can keep things under control. You will allow the accountant to allocate budget in three ways: manual, last year actual, and last year budget.   Chapter 26: Budget Report 147 After allocating a budget to an account its value is compared with the actual amount spent and the variance between these figures is reported in the budget report.       Chapter 27: Setup Accounts for Financial Statements 153 In this chapter you will create an interface where users will define accounts (from the chart of accounts) to produce the two most common financial statements: Profit & Loss and Balance Sheet.   Chapter 28: Financial Statements 159 The accounts defined in the previous chapter are used here to generate the two financial statements. These two statements reveal the financial health of an organization.   Chapter 29: Executive Dashboard 169 The executive dashboard comprises several charts. This graphical representation reveals the financial status of the organization to interested parties.   Chapter 30: Application Feedback 175 The application feedback is a feature which is added to allow interaction between the application users and its administrator.     Chapter 31: Application Security 189 After implementing a custom authentication scheme in chapters 7, 8, and 9 your next task is to implement the authorization policy. In this chapter you will create some authorization schemes to protect the application menus, pages, buttons, and processes.   Appendix 199 Book code as a ready reference
