4/15 – Ch 8 – Enterprise Applications

Quiz is Tuesday 4/22 – Chapters 5-8, Appendix B, C, Same format – 15 MC, 10 Fill in, 3 of 4 short essay
Group exercises coming up next 2 Thursdays in regular classroom (labs are all done)

Chapter 8 – Enterprise Systems (my least favorite chapter)

– Early systems were in accounting, payroll, A/P, A/R
BUT in Silos as they were standalone
– 1980s through today – “Enterprise” systems

UMass
– Blackboard/Canvas – Online Learning (linked for registration, but not grades)
– Wiser – Registration, Grades, Bills..
– Email – (Actually not at UMass)
– Blogs
– Simnet, Connect (Actually not at UMass)
– Website
– Payroll, A/P, A/R, Cafeteria, IT Requests

– Sort of integrated (same ID/PW) but not fully (no Single Sign On) like Amazon/Google
– “Legacy” systems – Are “old” – things have been around and might be/might not be integrated

– Big organizations (SAP) started to develop Enterprise Resource Planning system (ERP). Example of a large Enterprise System.

Three categories of Enterprise Systems
-Supply Chain Management (SCM)
-Customer Relationship Management (CRM)
-Enterprise Resource Planning system (ERP)

SCM (Supply Chain Systems)
Recall what supply chain is Fig 8.5
Raw Materials (Supplier) -> Manufacturer -> Distributor -> Retailer -> You
– Links systems across the whole chain.
– COMPLEX! Each entity has its own systems, and sometimes they enforce rules on the upstream & downstream entities.
– In Supply Chain, Money flows upstream & materials/goods flow downstream
– Some companies do it well – Dell with its JIT systems, Amazon, Walmart (RFID)
– Think what happened to it during the pandemic – fell apart…

Customer Relationship Management
– Focus on the customer, rather than the product.

ERP – As in SAP – Big systems that enterprise wide focus on the product, rather than customer/

Another example of doing Enterprise systems – Electronic Health Records

These days, ERP and CRM are merging and going to the cloud.
– Integration is NOT EASY.

Amazon, while doing SCM & ERP well, has had lots of issues
– Somali Immigrants – Working conditions are inhumane at many distribution centers
– Search for its own products – Antitrust issues with this
– Taking over our cities – Is it a monopoly?
– Literally shipping trash & counterfeit goods

Quiz 2 Study Guide

The format for the 2nd quiz will be similar to the last one – some multiple choice, some fill in the blanks, and some short essays which will come from this list:

Explain MIS infrastructure and some ways it ensures continuous business operations.  (Ch 5 – D/R, Scalability)
Discuss advantages and disadvantages of Cloud Computing, and why it is such an important development for MIS.
Identify the environmental impacts associated with MIS.

Describe a database, a database management system, and how they are different that spreadsheets.
Describe the important qualities of data (fig 6.4)
Define a data warehouse, and provide a few reasons they can make a manager more effective.

Explain the different network categories (LANs and WANs)
Explain topology and the different types found in networks.
Identify the different physical media types found in networks.
Differentiate the protocol between a circuit based telephone network and how the Internet works.
Describe the different wireless networks we use (think of your phones)

How is the focus of CRM systems different than SCM and ERP systems.
Why are enterprise systems so hard to implement

Words Bank for fill in questions:  Analytical, Attribute, Backup, Bandwidth, Bluetooth, Broadband, Capacity, Client, Cloud, Database, Disaster, Divide, E-R, Energy, Excess, Field, Geographic, Integrate, Internet, IP, Intellectual, Legacy, Managerial, MetaData, Modem, Primary, Protocol, Router, Scalability, Server, Single, Streaming, Transactional, Warehouse, Wide

4/8 – Ch 7 / Appendix B Networks and the internet

This the most technical, rapidly changing area of MIS we cover.
Fundamentals of radio waves – tradeoff between distance & quantity of data/ability to go through walls.

Here’s the words we know about telecom (definitions added):

– RFID/NFC – Apple Pay, Charlie Card & Fastlane to communicate over small distances
– Bluetooth – Up to 33′ data between phones/headphones/cars etc
– WiFi – Up to 1000′ based on evolving 802.11AC standard
– Cellular 3G vs 4G vs 5G vs LTE vs 6G – Up to 7 miles
– GPS – Satellite based (11.000 miles) one-way communication to determine latitude/longitude
– GIS – Geographic Information Systems (Maps, Traffic, etc) built on top of GPS
– Ethernet/Cat 5 – Twisted pair wire to/from Router
– Router – Routes traffic properly to the right computer/phone/alexa in your house- Modem
– FiOS – Fiber – Much better speeds than Cable
– Cable Modem – Deliver Broadband speed to homes & business
– Broadband – Always on and FAST (but 25 Mbps?? Really?)
– Dial Up, DSL – Obsolete technology that took over phone and was slow
– IP , TCP/IP – Protocol developed in 1960s to enable packet based communications
– ISP – Internet Service Provider
– Browser – Used for browsing the WEB – which is only a part of the Internet
– LAN and WAN – Technically, difference is distance but really it is whether I control the wires
– DSL, WiMax – Obsolete older broadband technologies over phone lines
– VoIP – Skype and other services which send Voice over IP
– Protocol – Set of rules to communication between nodes
– VPN – Virtual Private Network – Allows “private” tunnel communication over public internet
– DNS – Domain name system to turn domain names into an IP address like 127.63.45.87

Look at phones and radios inside them:
– Cellular (3G, 4G, 5G) – 7 miles 1G – 1st generation Analog, 2G – Digital, basic data, 3G – Broadband, 4G  & 5G  – Today
– GPS – Location (including altitude) and speed from satellites in orbits 11,000 miles up.  – GIS – Built on top of GPS to give Information (as in gIs)
– BlueTooth – About 33 ft (10 meters) – Speakers, Printers,
– WiFi – Distance depends on what is around. 1000′ or 5′.  – Talks to a router
– Phones can be turned into hotspots (essentially a router)
– NFC/ RFID / Airplay / Airdrop – phones talk to other devices

What about computers?
– Ethernet Card to Router via Cat-5 wire (Cat-7 is available these days)
– To Modem via Cat-5 (or sometimes Modem/Router are 1 piece of hardware)
– To ISP via Coax Cable (or sometimes fiber)
– To Internet via Fiber (FiOS) or Coaxial (Comcast, RCN) or Phone DSL (Verizon)

Web is PART of Internet – Mail, Apps, FTP, Telnet other parts.
All Internet communication is by a Protocol (set of rules) called TCP/IP
– Developed in 1960s and still works!  We are running out of addresses though (IPV6 will fix that)
– Breaks data into packets and sends over the Internet Backbone.
– DNS is system to turn Domain names (facebook.com) into IP address (173.252.120.6)

Nodes connected to each other by various topology:
– Ring, Star, Wireless or most commonly a hybrid.
– LAN (local) vs WAN (Wide) – longer distance means we can’t control the wires

For Code Lab 4/10

We are doing the “code” lab.  You can complete this on your own, or come to the lab if you want help.  This follows a global initiative to teach people about programming.  The lab is fun and easy (I promise!).  It is due by April 13 11.59pm.

Watch this video from President Obama  (https://www.youtube.com/watch?v=6XvmhE1J9PY) and this one https://www.youtube.com/watch?v=nKIu9yen5nc then work through the “classic maze tutorial for beginners” at http://hourofcode.com/code.  There are videos built into the exercises, and you can look at the code behind the scenes.  To prove you did the work, take a screen print when you are done and email it to me.  All the completed lessons will be highlighted, or it shows you a nice certificate!   If you can’t get it all done in one session, I recommend you setup an ID & signin so you can do it in more than one sitting.

4/1 – Ch 6 / Appendix C – Databases

Don’t forget that Simnet is due Sunday 4/6 11.59PM and LinkedIn (by email) at same time

What is a database?
– Holds data so programs have something to read
– Critical to development of MIS
– Development is by both IT people and “users” (business)

Umass Data Model
Student – Number, Name, Address, Phone, Email,
Class – Letter, Credits, Course, Term, Professor, Classroom?
Professor – Number, Name, Address, Email, Office, Office Hours, Dept, Salary

Usually portrayed with “entity-relationship” diagram
Entity – “person, place or thing” that is critical to business.
– Often called tables, relations or files
Attributes – Details of each entity (or fields)
– Has rules associated with each field (type, length, required)
– This is referred to as Metadata – Data about the data to enforce rules.  Ensures no GIGO
Record – One “row” in the database
– Must have a unique identifier called a “primary key”
– In E-R diagram, underline this primary key

– Draw lines with description when there is a relationship
– If one to many, use “crows foot”
– Put “0” where relationship is not required. “cardinality”
– Concept of Referential Integrity

DataBase Management Systems – Enterprise or Individual – Examples: Access, MySQL, Oracle
– Software package that lets computers store data
– SQL – Computer language that lets you create & update tables.  Standard across ALL platforms!
– Data Redundancy, Data Inconsistency, Data Security

Other terms  – Data Warehouse, Data Mining.  Being replaced by Big Data (see trends.google.com)

Fig 6.4 – Accurate, Complete, Consistent, Timely, Unique
DataBase Administrator (DBA) – In change of it all.  Especially security and Information Policies.

Slowly, Data Analytics & Data Analysts are figuring out how to use this data, especially visualization.

Compared to Spreadsheets (Easy to use, not a definitive source)
– No relations, no metadata, no primary key, limits on size, no automated collection, single user

Data visualizaion video 200 countries/200 years
Finished up by looking at how companies across many industries are doing data analysis

3/25 – Ch 5 – Infrastructures

Quiz 1 Results:

Average – Curved grades ASSUMING YOU ARE OK with connect
9:30AM class 30.7/40    12:30pm class 29.9/40   4:00pm class 32.8/40
34+ –> A
28-33.5   –> B
22-27.5 –> C
< 22 –> Less than C

Also shown is connect grade (circled number)
Connect – Out of 10 (5 smartbook/cases INCLUDING Appendix A). If you didn’t get 10, I will take late smartbook for 80% credit.  Note smartbook bug is showing 0% if submitted at all late- I will adjust this.

Simnet Labs are finishing up next week and due April 6th 11:59PM – Don’t forget to do LinkedIn assignment (setup a LinkedIn page, and link your Simnet “White Belt” credential) and email me your LinkedIn URL (format is like http://linkedin.com/in/jonfrankel)

Note final is Thursday May 22.  Do NOT make travel plans before – this is the only opportunity to take it.

Ch 5 Infrastructure – Blue prints for systems.  Talk about cloud systems first…

-Support Operations (current systems)
– Support Change (Future systems)
– Support Environment (E-Waste & Cloud)

Operations –
Downtime – HW crashes, Natural Disasters, Floods, earthquakes, 9/11 (from Ch 4 – fig 4.7)
– D/R strategy – Disaster/Recovery – How to get techie stuff back up and running
“Cold Site” – Restore data into that site. Time delay (“Warm site”)
“Hot Site” – Real time data available all the time. Very $$ (like Fidelity example)

Business Continuity Planning – More than systems
– Testing, Phone chains, All the logistics beyond the techie stuff.
– Physical Buildings – Where will people work

Change – Capacity Planning – Nice chart that we buy more than we have
– Lots of terminology here – most important (IMHO) is Scalability – How long can I keep running with current systems
–> being replaced by cloud computing (see below)
– 5 9s (99.999) availability standard, and how redundancy leads to fault tolerance and make it possible

E-Waste – Electronic Waste
– Rare Earth Elements (and other fun things like lead, mercury…)  – not good for environment!
– Only about 20% of e-waste is really recycled.
– Recycling is not always done properly
– Growing problem with no good solutions

Power Consumption – Cloud service / data centers use a tremendous amount of electricity. – This number is only going up, especially with AI.  And leads to more carbon emissions too.

Cloud Computing -IMHO this is the BIG change in MIS over the past/next decade
– All data is available all the time.
– In the old days, software wasn’t that good in the cloud
– Salesforce does great MIS systems in the cloud

Features – Capacity Planning (Support Change)
– Traditionally been difficult – Pay for more than you needed, upgrade frequently
– With the cloud, pay for what you use and can use as much as you want.  Like power grid.
– Way fewer resources like hardware & software (also includes people, who can collaborate easily)
– Backups & upgrades are automatic
– Disaster/Recovery automatic
– Systems Development is much simpler (more on this in chapter 9)

Downsides :
– Security – If hacked, or company goes out of business, then who knows what happens
(but they can probably do security better than most companies)
– They can raise prices easily or possibly sell your data
– Reliant on the Internet – These days, it is 100%* reliable
– Limited by the features they give you (which are usually fine)
– Don’t worry about the differentiation between types of cloud models (Iaas vs SaaS vs PaaS)

2/25 – Ch 4 – Ethics and Information security

For connect, note that once a smartbooks is past due, you can still “recharge” for partial credit but it will show a zero (I will fix the late penalty).  If you recharge to study for the quiz, it will NOT affect your grade.

First quiz is Tuesday 3/11 in regular class.  More details next week.

Tech Issues we have created in last decade (some to be discussed next week):

Privacy – Tradeoff of Security for Liberty.  Snowden, Pizza Order Video & NSA post 9-11 changes.  Since then, GPS, CCTV cameras/facial recognition/Clearview AI.  No easy answers here…

Identity Theft – Phishing – Trying to get information to commit identity theft.  Be smart!!
Use www.annualcreditreport.com – every 4 months (or weekly since Covid).
– Deter, Detect, Defend. (FTC.GOV/idtheft) for more tips.

Brains are changing – Long term memory, focused study, curiosity.

Encryption – Based on public & private keys. Works really well, as long as nobody figures out factoring 256 bit numbers.

Authentication – Proving who you are – Fingerprints, UserID & PW.
Authorization – What can I do.

– Intellectual Property

– Distraction & Complexity (think about GPS)

– Social skills – Changing communication

– Phishing -> Identity theft

Internet SHOULD NOT necessarily mean free.
– Intellectual Property – copywrite, patents, trademarks

Turning things off not always effective for security.  Humans First!

Misc Terms – Spyware, Malware, Firewalls.

2/13 – Excel Simnet Lab 1

0. We will meet in the blue lab (3rd floor library) for the next 6 Thursdays.  I will not be taking attendance and am here to help you complete the labs.  If you do them on your own, that’s fine.

** EXCEPTION –
I have to go out of town so on Tuesday Feb 18th you should do the 1st lab on your own
I will do the lecture on Appendix A on Thursday Feb 20th in the regular classroom

1. Signup for simnet at UMB.SIMNETONLINE.COM
(use code, or signup for courtesy access)  Bring headphones to Lab.  Be sure to choose “Frankel” section

2. Work through Simbook – Excel Lab 1
(show me, guide me, let me try)
–> the LET ME TRY is graded part!
– Use chrome, safari or firefox for best results in lessons
– if you run into trouble, don’t worry.

3. Work through Project – Excel Lab 1 Skills Review
– Practice only (not graded)
– Save your work to desktop / flash drive

4. Work through Project – Excel Lab 1 SUBMIT Challenge
– Counts! But only highest grade so resubmit if needed
– Save your work to desktop
(email if you don’t finish it)

– A tricky concept this week is the difference between absolute and relative addressing.  Absolute addressing is used to make copy/paste work properly when using formulas where one of the variable cells is a “constant” somewhere in the workbook.  I will demonstrate this in class if you can’t figure it out.

– if you have a mac, there is no “quick analysis” tool.  This is just a shortcut for doing sums.

Ignore due dates in simnet – all 5 excel labs are due April 6th.  As a guideline, complete lab 1 this week, lab 2 next week, etc.. don’t get too far behind.

You can work on this from home, either on your own computer or with Office365 (available from within UMB email) or via UMass’ virtual computer (see below).  If you work on it on your own computer or mac, you will need to save the file on an Excel 2021 machine before submitting.

All UMB students can download a free version of Excel via webmail!!  From your email, click the “Office 365” link (top left), and then “Install Office Apps” (top right).  Note you may need to upgrade your Mac Operating System to get this to run.  I can help a little here, but I’m not really a Mac expert. The IT helpdesk (3rd floor of library) is a great resource.

Virtual computer Instructions:
– go to https://www.umb.edu/it/cloudpc
– enter your current UMB id & PW (twice actually)
– Click on the “general desktop” and Voila!  You can now run office 2019 from the Virtual session.
– You will need to deal with onedrive to work on your projects.  Personally, I hate onedrive – it’s cumbersome but does work.
