My recommendation to ensure an ERD accurately represents a particular event is to make sure it accounts for the dynamic nature of events. When designing a database, if it represents the state of things as they are today, it may not accurately represent the state of things tomorrow. Building in the ability to change the structure based on new information would be a beneficial design. In addition, I would recommend being very clear in your attribute descriptions to ensure that the correct data is captured in the appropriate place. For example, if you have a attribute “phone number,” this data could represent the phone number of many entities, so making sure you have clear descriptors is key.
-
Jenn,
I completely agree. If a company employs outside consultants to create a project, it is extremely important that the outside firms uses the same language as the company. As Jenn mentions a phone number has various meanings including cell, or house, or even office numbers and it is important to make sure the attributes are precise.
-
-
I would consider a completed ERD to be knowledge because it integrates information, context, and insight. The information part of the ERD is the “how our business process works” at the time at which the model was created. The ERD also has insight into what types of relationships exist between the entities and what attributes are characteristics of the entities based on the context of the ERD model.
-
For an ERD to correctly represent the business event, the assumptions and requirements should be correctly understood. If our assumptions are incorrect , the ERD will be an incorrect representation. For example, if we think the relationship between two entities is ‘one to many’ instead of ‘many to many’ , we will end up missing a table when we build a database from ERD. Also, as discussed in class, the context is important to derive the necessary attributes and define relationships between different entities.
-
I think an ERD would be a form of data and information. The knowledge would be present in the database and the reports that are generated.
-
I see the ERD as being knowledge since it’s a map of a process. It’s more than just data and information because there are relationships and associations built into it that make it a map. I think those characteristics make this knowledge.
-
Q2:
I would consider an ERD a form of information. It contains data, which is interrelated and integrated into a system providing information for the end-users. The end-users, however, may derive knowledge from the information they are extracting from the database. Knowing how to use specific queries, relevant information may be extracted that can be further used to make some data-driven conclusions that represent knowledge. -
Advice for an accurate ERD: Before beginning the process of formulating your ERD take a step back and analyze your business situation from a macro view. Ask yourself, “What do I truly want to understand given the data at my disposure?” Familiarize yourself with the key economic drives essential for commercial success and test those against industry standards / norms. As ERD represents a systematic process for Data to Knowledge acquisition, it is important that you begin with the proper inputs before moving forward.
-
A key component for successfully designing an ERD system is to incorporate outside stakeholder perspective prior to committing to any details. This will help lend additional detail in how stakeholder information might be communicated into the ERD while also ensuring individual bias is minimized. While final decisions need to remain with the internal group, including other stakeholders creates a sounding board through which the process can be audited.
-
Q2:
I agree with most of you who say ERD is information. Information is defined as capturing data. ERD represents the data in a concise form that is easier to understand. However, in order to understand ERD there does not require any specific analytical or cognitive abilities. For those of us who are familiar with the ERD structure and terms, understanding ERD becomes real easy. Any decision taken based on this ERD is knowledge since it is based on both data and analytical abilities. -
I would consider an ERD information. It contains data in a very organized and ready to use fashion and can be easily converted into knowledge. But, it is not knowledge by itself. An outsider to the organization could not look at the ERD and determine the best course of action. Knowledge still must include experience and an innate feel for the industry.
-
ERD helps to understand the organization’s data needs and serves as a schema diagram for the required system’s database. Therefore, I would say ERD is information. However, it will be considered as knowledge when it is processed further to make a decision.
-
One of the key attributes of an ERD is the relationship between entities, especially the role of the key attribute and the foreign key. The creation of tables and their relationships was seen by me as the most important part of creating such models. The mapping of several entities together is what converts this data into knowledge and a wrong mapping of entities can lead to knowledge being represented wrongly. This is one aspect to be carefully studied before creating an ERD.
-
To make sure an ERD represents the business event it is supposed to capture I think it is important to thoroughly understand all of the entities at play. Information solicitation techniques such as stakeholder interviews, observing the business event, or employee workshops would be a great way to make a MECE list of entities in the business event. Without all of the entities, it would become a lot easier to overlook a relationship or attribute that is important to track/understand.
-
For ERD to work efficiently, its important to correctly define the attributes , then its important to identify the relationships, be it one to many or many to many and finally its important to note and identify the primary keys or unique identifiers. I think assigning more importance to any one variable will lead to wrong assumptions. The model is based on a series of dependencies and those attributes should be correctly identified.
To you your second question, each variable in itself is a data point on the ERD and together they generate some information, for us to assign the tag of knowledge we must then make ERD more fluid and adaptable with a series of changing scenarios. -
2) I would consider ERD as information. ERD gives us an idea about how and in what manner different entities are related. Also, the characteristics of each of the entities. So, overall it is a very useful tool in the understanding the whole framework on the database. Someone can just look at a complete ERD and understand business logic. Also, ERD tells us how a change in one entity affects other related entities. Therefore, ERD is definitely information.
-
ERD diagram though gives an idea of the data in the organization, we can tell the relationship between different entities and hence it would give us the information about what is going on in between different entities and their attributes and their dependency in an organization.
-
When thinking about how an ERD model accurately depicts your business, you first need to evaluate your business strategy from top to bottom. Make sure your company is aligning its strategy with its overall organizational goals and then use the ERD model to more efficiently organize your business structure. I would say that one needs to lay out all aspects of the business from the product to the services used to deliver to the prospective client. There needs to be the correct entities and attributes as well as the correct relationships between each entity. Once this is done and everything is rightfully placed, a company can gauge a better understand of the overall business needs.
-
I would say a completed ERD model is considered information. Data is then extracted from the information in the ERD model. You cannot collect data through an ERD model relationship because the data is within the ERD model. It does not present data, it presents a relationship within information using data.

-
I consider ERD diagram as a a source of knowledge. It not only sheds light on data but also gives the interrelationship between various entities. Also, the relationship dependent attributes are also explained. This gives a holistic picture of the whole system.
-
I would consider an ERD an example of a mix of the three – data, info, knowledge. The information is needed to build the ERD example and from it we can interpret the data which forms knowledge on the subject matter. By essentially drawing the map, we can better understand the relationships amongst different entities and how one effects another.
-
I consider the ERD model a form of information from which a business manager could draw knowledge. The model takes data, which in its simplest form could be a list of entities with each one’s attributes listed under, along with a short explanation of the relationship to other entities, and translates the data into a visual diagram. This diagram encapsulates the data as information that describes the entities and relationships of a particular system. With a sophisticated perspective on the ERD model, a manager could analyze this visual information and convert that to knowledge of the relationships, which he/she could then combine with other knowledge of the system to provide wisdom to the other stakeholders involved in the system.
-
It is imperative that the business event is clearly described and articulated in order for the ERD model to work. It is crucial that the details are presented in a manner that are easy to follow and that the relationship between the entities and attributes can be followed. Without clarity, a detail can be lost that will alter the relationship. Definition of the entities and attributes and the relationships determine the ERD model. This is how the ERD model can ensure it clearly depicts the business event.
-
I would classify an ERD as a form of Information in that, it takes data points (entities/attributes) and organizes them as they relate to one another (relationships). An ERD stops just short of knowledge because an ERD is simply architecture. In order to take the next step to knowledge, the ERD needs to be put to use and insights drawn from its design. Only then will there be knowledge drawn from an ERD.

Strategic Analysis – Individual assignment, 30% of total grade
Due October 15, 2014
The strategic analysis is the “take home” final for this course. Please start thinking about a proposed topic immediately. We will use the first class session to brainstorm further and a list of your proposed topics is due per the class schedule.
Name or other description of the technology. Include a URL if available.
A brief one or two sentence justification of why it is interesting to you and in general.Requirements
The goal of the strategic analysis is to analyze an information technology that will aid a decision maker in determining if it is useful for further investigation and potential adoption.
Prepare an analysis of a technology or an application. You may use your own firm as the contextual basis for this analysis or you may assume a specific context of application.
Summarize your analysis in a set of no more than 12 PowerPoint slides. Use the main slides to communicate the key points in a concise and direct manner. You may use the “notes” section on PowerPoint to add more detail and justification. Do not fill the main slides with text. The slides should minimally include:o Executive Summary: one slide reiterating your key points (i.e., the elevator pitch).
o Example of Usage: 1-2 slides describing a real-world use of technology.
o Business Value: 1-2 slides describing how the technology delivers value. As well as potential pitfalls.
o Technology Specifications: 1-2 slides providing additional relevant technology details.
o Competitive environment, customers, and disruptive potential: 1-2 slides describing major competitors, competitive positioning and environment.
o Analysis: 1-2 slides providing a bottom-line analysis of when, how, and why this technology will be beneficial to potential adopters as well as risks and costs.
o Bibliography and References: One slide listing additional resources to learn more. Might include websites, articles, videos, etc.
You are not required to follow the order above. Order the slides so that they help you make the best possible case. Submit the analysis via email to me at swattal@temple.edu. The file should be in Microsoft Powerpoint (.ppt or pptx) format. Late submissions will not receive assignment credit.

Case study analysis – group assignment, 20% of total grade
In addition to reading and preparing to discuss all of the assigned case studies, you will also analyze and lead the discussion on one case during class. Each case will typically have two students, and when that is the situation, you will be expected to challenge the views of your classmate. Please focus your analysis on the provided discussion questions.
A good case study analysis includes the following:
Specific details are cited regarding facts and problems of the case study. Instead of general observations about information technology or organizations that apply to virtually any problem, specific details are drawn from the case study itself.
At the same time, each case study is specifically chosen to illustrate general lessons. Thus, after analyzing the details of a case study it is appropriate to discuss how specific issues in that case study have broader application beyond that immediate case study and to the class materials.
Provide a balanced perspective in analyzing the case study. Include both pros and cons. When making a recommendation explain both the rationale for a recommendation (the why) as well as its feasibility (the how). Well-considered recommendations include discussion of potential threats to success as well as rationale for an organization’s ability to overcome them.Summarize your analysis in a set of no more than 5 PowerPoint slides. Use the slides to communicate the key points in a concise and direct manner. Submit the case study analysis via email to me (at swattal@temple.edu) – at the start of the session when the case study is to be discussed in class. The file should be in Microsoft Powerpoint (.ppt or pptx) format. In most cases, the instructor will call upon you to informally present the submitted slides during the relevant class session. A formal presentation is not required.
Please post your group (name and email id) as a comment to this post!!!
