Happy B-day SMS {3}

by Claudia J
Today being the last blog, I decided to write about an interesting article written by John Biggs which talked about the history of the SMS. The article was called “Happy Birthday SMS” which caught my attention right away. This article discussed how a programmer from the United Kingdom in December 3rd from 1992 sent by the very first time a few lines of messages saying “Merry Christmas” from his computer to his friend’s phone. He sent his messages through the “new” technique known as short messaging service (SMS). However, this new way of communication didn’t become so popular and into effect until sever years after. Today there are about eight trillion messages crossing the air yearly where only adults between 18 to 25 years old send about 133 messages a week. read more...

SQL Injections {1}

by Claudia J
The article that I picked this week was a peer reviewed called “Preventing SQL injection attacks in stored procedures.” The author talks about that an SQL injection attack mainly targets interactive web applications that use database services which accept user inputs and use them to form SQL statements at runtime. It also says that an SQL injection attack the attacker usually provides malicious SQL queries segments that cause the database to result in different requests.
From what I understood from the author is that it results hard to avoid this type of attacks. It mentions that one way is to examining dynamic SQL query semantics at runtime but is not 100% secure that will not get SQL injection attacks. The author proposes a novel technique to defend against the attacks targeted at stored procedures where application analysis with runtime validation will help to eliminate the occurrence of such attacks.
The authors go in depth on other types of queries we can use to help prevent SQL injections. SQL injection is a very common technique hackers use to attack underlying databases by altering the programs behavior. This article is good because it connects to the class content specially right now that we are in the middle of a project and working with SQL queries. It gives us an insight of the type of vulnerabilities that are out there when programming. It is important to try to make sensitive files of our databases “hard” to find to make it harder for hackers to get into our system.

From Big Data to Big Impact {2}

by Claudia J
I picked the article called Business Intelligence and analytics: from big data to big impact that talks about how these areas of study was created due to the urge to manage the excessive amount of data being created and the need to classify and analyze this data to use it as efficient as possible. According to the MIS Quartely after conducting a survey with over 4,000 IT professionals from about 93 counties in different industries the IBM tech reported in 2011 that business analytics is one of the four major technology trends in 2010. It also mentions that McKinsey Global Institute predicted that the United States will have a shortage of people with well-developed analytical skills by 2018. read more...

Big Data.. .the new job source??? {3}

by Claudia J
I picked the article that talks about how the big data boom is expected to generate large numbers of IT jobs in the US by 2015. According to Gartner, an IT researcher, predicted that there will be around 1.9 million more IT jobs but the unfortunately the issue will be that there aren’t enough trained people to take over the jobs. read more...

Hey! You! Check out Apple’s Cloud! {2}

by Stephen O
Summary:

Apples long awaited iCloud Service was unveiled on the 12th with the free IOs 5 update that was released on the 12th to anyone who has an apple ID (mind you Apple ID’s are easy and free to get and setup). Cloud Services are increasingly becoming more and more popular, despite some concerns (Privacy and Legal) the amount of cloud services sprouting up every year is amazing. Evernote and DropBox, and GoogleDocs are some of the popular ones students and business professionals may be more familiar with right now. iCloud is Apple’s entry into the market of cloud services and like how MySpace, Twitter and Facebook and other social media have revolutionized the way we use the internet we can expect cloud services have the same impact.  “iCloud’s main purpose is to cut the cord between iOS devices — such as the iPhone and iPad — and PCs. Starting with iOS 5, Apple will back up user data to the Internet automatically, making it available to Macs, Windows PCs and other iOS devices without wires. The services at iCloud.com are just one-half of the equation for accessing your data on a PC or Mac. The other half is iTunes, which can be used to manage music, TV shows, apps and e-books.” (Newman, 2011)
Though this is only part of the interesting part, this is a calculated step to hinder Windows 8, which in itself will also have a cloud service available to its users. By having a cloud service available first, they have time to perfect it, add new features, and get it right before Microsoft has theirs even out of the gate. read more...

Time to move on to something…better {1}

by Stephen O
Summary:

When is it time for something new? When is a good time to trade up? Is it similar to buying a smart phone? Waiting for the new model later that year? Is it when the industry chooses a standard like Blue Ray or VHS? On the other hand, is it like buying a car and it no longer can perform reliably the duties we purchased it for? When is it time for us to transition to the next generation of Data Modeling?  In the article “Toward a Next Generation Data Modeling Facility: Neither the Entity-Relationship Model nor UML Meet the Need” the author went about explaining why perhaps it is time to move on towards the next generation of Data Modeling.  They defined five wanted characteristics of a Data model. read more...

ERP and the users’ view {Comments Off on ERP and the users’ view}

by Stephen O
Summary:

All of us use an ERP. Whether you knowingly use it, use it in disdain, or unknowingly do so. If you are a student at California State Polytechnic University, Pomona you are familiar with Bronco Direct. It is the software that we use to add/drop classes, search for classes, check holds, register for tests, and see when your financial aid disbursement is. Most college campuses have an ERP System, in fact, Mount San Antonio Community College switched just a couple years back to their own My.Mtsac ERP software. Now before I go any further ERP stands for Enterprise resource planning.  It is the software that is used for many business functions such as  Finance/Accounting, Human Resource management, supply chain management, project management, customer relationship management, data services, and access control. “. They evolved from standard inventory control packages to material requirements planning (MRP) and manufacturing resource planning. Enterprise resource planning (ERP) is now considered to be the price of entry for running a business.” (Yu-Min, 2006) I know if you are like me you cringe when it comes time to register for classes, and Bronco Direct otherwise known as Peoplesoft, is down.  ERPs can be complicated, complex, and expensive to install and there has to be some way of evaluating to see if an ERP system is even necessary and once it is installed, just how successful such a system might be. In Taiwan, they used 264 people and subjected them to a newly installed ERP system. “The results suggest a ten-item instrument to measure three components of ultimate-user satisfaction in an ERP environment: ERP project team and service, ERP product, and user knowledge and involvement. This study has conducted a rigorous scale development procedure to establish a reliable and valid instrument for measuring ERP ultimate-user satisfaction.” (Yu-Min, 2006) Through this study they established a valid way to measure ERP Ultimate-user Satisfaction. read more...
