Questions: 1. There are several concepts that are present in almost all business software applications. Understanding these concepts makes it much easier to design business applications, to ensure that they do not violate the domain rules, and to adapt the applications to changing requirements without the need to change the overall architecture. This is known as REA (Resources, Events, Agents). What are the most fundamental REA concepts?

2. While most large databases (ORACLE, Sybase, etc) are only database engines, they are commonly accessed from a separate "client" application via a special database access language. Integrated database development environments usually contain their own (often proprietary) database engine, making the creation of self-contained applications much easier. Accountants may be involved in several aspects of database development. In which area would accountants least likely have involvement when developing a database system?

3. Well done. By sharing your experiences, we can learn from each other. What are some of the software suites and business application software package which you have experience using? What are some of the features of the applications in the suites and packages? How is information generated in the individual programs stored?

4. It is definitely a good idea for a business to do a thorough research before considering an accounting system. Again, it is important to consider the need of a particular industry, since different businesses expect different functions and output from the system. But in all cases, good AIS should be user friendly, have good transaction orientation, reporting capabilities, and sound internal controls. What may be other suggestions?
