2. The Tool (Planning Sheet)
Question
How is this paper related to Information Systems Education?
Answer
Shows one good method of planning, designing, and creating error-free information systems
What is the key issue?
A tool called the planning sheet that uses Information Engineering principles to develop effective information systems
What is being learned?
The planning sheet is an excellent instrument used to optimize data tables information systems use

3. The Tool (Planning Sheet)
The planning sheet is used at the information level during the database design aspect of an information system
Adopts the data modeling approach of the planning phase of information engineering
model data to meet the reliability requirement stipulated for the data tables used by an information system
The sheet is used to:
Document the characteristics of data tables of an information system
Ensure that the information system’s data integrity is enforced
Ensure that the user requirement is met

4. The Tool (Planning Sheet)
Uses both descriptive and problem-solving approach to mark out required rules
These rules are the underlying factor for establishing the reliability and the dependability of data within data tables of an information system
Shows how data integrity constraints are defined for each attribute of relational tables an information system uses
Assists in making an information system reliable
Serves unique and different functions from Normalization process and Entity-Relationship model

7. Information Engineering
Hoffer, Prescott, and McFadden define information engineering as “data-oriented methodology to create and maintain information systems.” They emphasize that within the context of information engineering, data are modeled to meet the needs of the enterprise, not by data usage
In his article, From Data Engineering to Information Enineering, Wiederhold (2004) writes that since information engineering focuses on “information”, dealing with the planning of information requires new engineering concepts if the data used to generate information is to retain its worthiness

8. Conclusion
The fundamental function of information engineering is finding new ways for creating efficient information systems, including its components such as the database that stores the information system’s data, for improved performance
The fundamental roles of information systems are to generate reliable and dependable information
The second level of the planning phase of information engineering that conforms to the planning sheet focuses on planning, data modeling, and establishing data worthiness for data tables during the database design phase of information systems development
The planning phase of information engineering governs database rules and the authenticity of tables’ data
