¶ … eCities composes of the annual research that assists local communities to measure and benchmark their performances in order to foster economic development, entrepreneurship and job growth. The eCities also aims to create environment that will enhance expansion of business organizations within the communities. More importantly, the eCities allow the local governments to implement their projects using the online interface that connects 32 items, six factors, township, empirical index and village level data. The benefits that the eCities deliver to the stakeholders make the policy makers to decide expanding the eCities information systems to assist the organization to deliver benefits that are more meaningful to all the stakeholders.
Objective of this project is to design information systems for eCities. The project develops a data flow diagram that provides the goals of the information systems and the computer programs that will be required for the systems.
Data Flow Diagrams
A DFD (Data Flow Diagram) is a graphical representation that reveals the flow of data within the information systems.
Fig 1: Data Flow Diagrams
As being revealed in the data flow diagram, the system will perform the following functions:
1. Adding, deleting and editing student and administration researchers
2. Adding, deleting and editing communities
3. Change of the current year for the data analysis and entry
4. Editing community data
5. Changing the email templates
6. Change of text on various reports and pages
7. Importing historical data
8. Factors and Index export
9. Database Access and Webhost
However, the eCities organizational functions are too complex to be captured only by the data flow diagram. The project decomposes all the functional processes with more explicit level 1 diagram (level 1 DFD).

Conceptual Data Models
The diagram below reveals the conceptual model that consists of Entities Administration, City, Demographic and Community. The model also reveals the relationships between these Entities.
Logical Data Models
The logical data model reveals the relationships and attributes of each of the Entity.
The diagram below provides the eCities context diagram.

Process 1
INPUT the DATA Username, Password, First name, Last name, Email Address in the ADMINISTRATION
If Username and Password is correct
Then allow to log in Else

The decision table shows that the Administration will be required to input username and password before he or she can log in. Moreover, the decision table reveals that the City can have financial data, tax data census and demographic data. Additionally, a user should input username and password to access the data and if input a wrong username or password, the system will flag an error. In addition, community can have City 1, City 2, City 3 and City 4.
The decision trees of the eCities information systems are revealed below:

Conclusion
The project presents the data flow diagrams for the eCities information systems. The data flow diagram reveals all the entities for the systems. The conceptual flow diagram provides the relationships and the attributes of the entities. The decision tables and decisions trees reveal the logical processes of the systems and the rules to follow when a user accesses data within the systems.

In the contemporary business environment, the accounting profession has undergone a fundamental change, and the traditional accounting systems are no longer adequate to satisfy a recent accounting domain. Thus, a call has been made to expand the scope of accounting information systems. In response to the call, the REA data model was launched to support the accounting information systems. The REA data model is identified as the conceptual modeling tool
Pedagogic Model for Teaching of Technology to Special Education Students Almost thirty years ago, the American federal government passed an act mandating the availability of a free and appropriate public education for all handicapped children. In 1990, this act was updated and reformed as the Individuals with Disabilities Education Act, which itself was reformed in 1997. At each step, the goal was to make education more equitable and more accessible to
(Braunschweig; Day, 150) Most of the current generation of project managers expects the project management tools to furnish them with almost real-time knowledge in order to facilitate their decision-making. Some of these tools like DOFF, "Field of the Future," "Smart Fields," Microsoft's "Oilfield Connectivity" and i-Fields are currently being examined by exploration and production oil companies. Some of these tools have the capability of generating information from apparently incongruent data
