I believe this decision on approach of when/how fully implement is based on the organizations opinion, and preference. If a company were to base their decision on urgency (which is a no. no) I would run the new and old system parallel to ensure that data integrity is still in place.

HI Xiaomin,

I like that statement. I never heard that before…

I can say for sure that I misused some of the narratives when I completed my diagram. This is not to say that my diagram is incorrect it just means my interpretation of the information differed. As stated by Dongjie above the diagram should have a few evaluate elements (i.e…[Read more]

Hi Dongjie,

Excellent point. The key elements must be in place to assist in evaluating the diagrams. Therefore, it is not needed for the evaluation of the class diagrams to occur.

Hi Binju,

I agree. I am certain that everyone’s diagram look different. However the relationships between elements should be consistence. ON the other hand if the relationship differed the structure of the diagram would be false and never cohesive.

Hi pascal,

Correct. Can’t help but ask myself why would any organization/project move forward without conducting a data analysis. Preforming adjustments is tedious and time consuming, and I rather take the time spent possibly completing an analysis to insure data integrity.

Hi Dongie,

I agree with your statement about data modeling not only creating the structure of the data but also with the data will be located. Skipping the data modeling process and going straight to production is risky and can lead to system failures.

Hi Xinteng,

You raise an excellent point and I agree. Not analyzing the needs of the data before designing the physical database will directly impact the integrity of the data and can be risky. In turn causing loss of data and efficiency as well as a possible loss in revenue.

Hi Ami,

I agree and I believe that moving straight to design prior to analyzing the system is irresponsible and will waist time and increase cost. Not to mention it’s a true recipe for failure.

Hi Derek,

I agree with your comment about streamlining communication within the organization by instituting standard molding techniques. As an IT auditor I would rather that an organization have a modeling standard opposed to not having one at all. Reviewing different standards throughout different organizations would be much more…[Read more]

Hi Tamika,

I agree. Modeling standards will allow an organization to remain consistent as it relates to documentation updates, and keeping them relatively similar.

As you pointed out data modeling standards assist uses, Developer data analyst as well as you pointed out auditer. Data modeling will assist in the audit review by…[Read more]

Hi Vittorio,

I agree with your statement about uniformity and possible human error. Data modeling will assist with keeping data systems uniform and ensure that the lines of communication are clear.

Pascal,

You raise a great point!! Data modeling is important to save an organization time as well as reduce cost. Data modeling asset with provide the organization with a better understanding of the functional system requirements. Organizations that don’t use data modeling risk miscommunication with regards to designing, and structing the…[Read more]

Hi James,

I definitely agree with your statement. Alignment of IT and the organization’s strategy is critical, and in order to achieve success communication is key.

Hi James,

I couldn’t agree more. To date the project I referenced in my post has not been approved, and I believe this is a direct result the project not being supported by our stakeholders.

A funny thing… Over the years I have been privy to several projects, and what I realized is if the stakeholder’s buy-in is not there the projects…[Read more]

HI Iyana,

You make an excellent point and I agree with your post. Visual impairment absolutely hinders a user’s ability to read or to interact with a system. Being visually impaired can also hind someone from your a cell phone. We quickly forget that people with impairments can’t always utilize the new thing or the normal thing (cell phone) a…[Read more]

Hi Karabo,

Thanks for sharing. For the life of me I couldn’t recall the system (wheelchair?) that was used to make the selections as you described.”To make selections, individuals use switches activated by movement of the head, finger, foot, breath, etc.”. I have never seen this used in person. However, I know of at least one person who…[Read more]

Hi Sarush,

Thanks for sharing, because I had no clue about the great enhancements that were created to assist autism. I especially did not know about the touch window as you discussed. My uncle is legally blind, however he has a very small fraction of his site. Nevertheless, the center for the blind assisted me in getting him a special reader…[Read more]

Hi Linlan,

It is important that HCI are the core aspects of system development. The below link discusses how we can work together to assist people with disability who wish to use a computer. They talk about people in wheelchairs not being able to sit under a desk, or some with limited mobility of their arms not being able to use a standard…[Read more]

Hi Pascal

I agree with your comment about “A computer should be able alert a user with an icon or pictures to enhance accessibility”. Computer and the environment could be adjusted to assist in one’s disability. I located a web page (below) that provides information and tips on accommodating web users with disabilities. According to the link…[Read more]
