1. More often than not, database environments in an organization reflect data structures that have been developed over a period of years, sometimes haphazardly, and that often reflect a variety of architectural styles and structures. Look at the existing database environment in your organization or school or in a local company.
a. What is the age of the oldest information system used in the organization?
The oldest information system used at American International Group (AIG) is the online employee registration system. This system has been in use for the last 25years. The online database of employee information is useful for providing information to the management of the company. The information obtained aids in making choices for AIG.
b. What is the age of the newest?
The newest information system at AIG is 2years.The name of this system is the Accounting Information system. The accounting information system was adopted in order to cater for the emerging accounting needs of the company (Hoskins, 2010). The accounting needs of the organization were addressed after the introduction of the accounting information system. This implies that the system has gone a long way in terms of pushing the organizational agenda.
c. Does the organization have both traditional file-based systems and modern relational database systems?
The company operates on the basis of both the traditional and modern based file systems. For example, the online registry of employees mentioned at the onset is a traditional file based system while the accounting information system is a modern based organizational file system. Both file systems have been instrumental in terms of consolidating the data and information needs of the company. For ...

...the sake of my business needs. This because the enterprise architect depends on how well the management of the organization is ready to follow the guidelines as outlined. The enterprise architect additionally is cost effective and creates a positive impact towards organizational operation. The use of tool has benefited organizations in many ways.

As technology progresses it can truly change how a business operates in terms of accounting and financial reporting. Online software has become a widely used system by many businesses around the globe. Financial reporting is essential to any business especially when seeking for potential investors or stakeholders. The reason being is because a financial report contains all of the records of how a business is performing financial wise. Likewise there are purposes of securities regulations and the main one is to disclose any schemes.

A framework is a set of classes that supports reuse at larger granularity. It defines an object-oriented abstract design for a particular kind of application which enables not only source code reuse, but also design reuse [Johnson & Foote, 1988]. The framework abstract structure can be filled with classes from its own library or application-specific ones, providing flexibility for the developer to adapt its behavior to each application. Besides flexibility, a good framework also increases the team productivity and makes application maintenance easier [Fayad et al. 1999].

Given the time, it takes to develop large sophisticated software systems it not possible to define the problem and build the solution in a single step. Requirements will often change throughout a projects development, due to architectural constraints, customer’s needs or a greater understanding of the original problem. Iteration allows greater understanding of a project through successive refinements and addresses a projects highest risk items at every stage of its lifecycle. Ideally each iteration ends up with an executable release – this helps reduce a projects risk profile, allows greater customer feedback and help developers stay focused.
I am interested in conducting research and teaching in managerial accounting, auditing and assurance services and accounting information systems. In particular, I am interested in exploring the role of accounting information systems in decision making, internal control, and auditing. In order to gain an appreciation of these and related issues, it is essential for me to have a strong grounding accounting, accounting information systems, information technology, managerial accounting, as well as gain a general economic and management perspective.
In order to complete, many projects are finding it advantageous to use a lifecycle approach. One of the reasons software project management remains a challenge is that, as has been all too frequently observed, progress in software development has not kept pace with progress in hardware development. The gap between software and hardware development is partly explained by the lack of standard methods and tools to boost the software development process. In short, "The cobbler's children have no shoes."
The Unified Modeling Language is a standard language for specifying, visualizing, constructing, and documenting the artifacts of software systems, as well as for business modeling and other non-software systems. The key is to organize the design process in a way that clients, analysts, programmers and other involved in system development can understand and agree on. The UML provides the organization. The UML was released in 1997 as a method to diagram software design, by some of the best minds in object oriented analysis and design. It is by far the most exciting thin to happen to the software industry in recent years. Every other engineering discipline has a standard method of documentation. Electronic engineers have schematic diagrams; architects and mechanical engineers have blueprints and mechanical diagrams. The software industry now has UML.
Within the analysis phase a set of goals are needed within the domain. From this there are three perspectives which are taken; the object model the Ronald LeRoi Burback (1998) states “dynamic model, and a functional model. The object model represents the artifacts of the system. The dynamic model represents the interaction between these artifacts represented as events, states, and transitions. The functional model represents the methods of the system from the perspective of data flow.” After the analysis phase the system design phase takes place. Here the system is sub-categorized and appointed tasks and persistent data storage is established, also within this phase the architecture is formed. Lastly the object design phase starts and is where the implementation plan is established and algorithms and object classes are also
Requirements engineering begins during the communication activity, continues into the modeling activity, and builds a bridge from the system requirements into software design and construction. Through requirements engineering, there is an examination of the context of software work performed. It is essential for the software engineering team to understand all requirements of a problem before the team tries to solve the problem. An identification of specific needs that the design and construction must address is also included. Further is a need for the identification of the priorities that guides the order for the completion of work. This i...
Databases are becoming as common in the workplace as the stapler. Businesses use databases to keep track of payroll, vacations, inventory, and a multitude of other taske of which are to vast to mention here. Basically businesses use databases anytime a large amount of data must be stored in such a manor that it can easily be searched, categorized and recalled in different means that can be easily read and understood by the end user. Databases are used extensively where I work. In fact, since Hyperion Solutions is a database and financial intelligence software developing company we produce one. To keep the material within scope I shall narrow the use of databases down to what we use just in the Orlando office of Hyperion Solutions alone.
The BPM discipline has been built with the basis on office automation, work- flow management, operations research, lean manufacturing, six sigma, and business process reengineering [[60][61][56][11]].
Therefore, AIS has several roles. A main role is to integrate all information system for effective management within a company, connecting different departments with relevant information. Another role is to assist the organisation to make decisions by preparing different reports and evaluating information. It also provides a company with a control and safeguard internal information ((Kim and Solomon 2006).
The following essay aims to analyse in depth a computerised accounting system and its aspects such as its history, what technologies is based on, and how it has developed since its beginning. Other aspects such as the current state of the system and the interactions with other systems and the future of the system will also be covered in this paper.
