Cloud Computing Using Oracle Application Express

Chapter 1: Introduction to Cloud Computing and Application Project 1The 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 9First 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 13The 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 15Each 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 25You 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 29You 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 35Assigning 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 43In 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 47The 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 53Different 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 57Cost conscious organizations always keep both eyes on their expenses.
