What is system integration?
IT infrastructure includes a variety of different systems.
Organizations use different systems in various areas which often need to work together, perhaps by even retrieving data from one another.
What is software development?
Software systems implement various algorithms that transform data from one form to another, perform calculations, manipulate files, or complete other tasks that might be repetitive, time-consuming or dangerous to an employee.

What is the data pyramid?
A concept that visualizes the data-information-knowledge-wisdom hierarchy
What are the 4 main concepts of the data pyramid from top (point) to bottom (base)
- Wisdom: Applied—it is dark, I better turn the light on
- Knowledge Context—The room I am working in is getting dark
- Information: Meaning—it is 638 PM the light switch is turned off
- Data: Raw—1838, on, off
What questions should you ask of data to process it into a usable form?
Who, What, Where, Why, and How?
Information can be _________________ or _____________
Structured or Unstructured
What is the key word associated with knowledge?
Context
What is connectedness wisdom?
Essential the path to connected understanding when interpreting data. It is that human element leveraging intelligent technology components when attempting to make fact-based decisions.
What are a couple of examples of structured data?
Contact information such as first name last name, email address, and phone number.
Also, quantitative fields like DOB, Date of Transaction, and the amount received or due.
What are some examples of unstructured data
4
- Unstructured data includes data stored in a text or video format
- Comments on a web page
- Text messages,
- Video presentations or conferences
What is the difference between structured and unstructured data
The form in which it is stored.
What are the 3 core variations of cloud based (Data management) systems
- Infrastructure as a service (IaaS)
- Platform as service (PaaS)
- Software as a service (SaaS)
What is laaS and what does it provide
Infrastructure as a service cloud based system
Provides access in a virtualized environment and the computing resources are composed of virtualized hardware. This includes things like network connections, virtual server space, and load balancers.
What is PaaS and what does it do?
Platform as a service cloud system
Customers have access to a platform that supports the development and management of web applications. Enables quicker development life cycles and reduced infrastructure requirements since the majority of the processing happens in the cloud rather than on local storage and processor resources.
What is the difference between PaaS and IaaS?
The difference lies in who manages the switching, routing, and operating systems.
If the client is responsible for licensing the OS and managing the back-end networking, it is considered IaaS.
If the cloud service provider is responsible for licensing the OS and back-end storage and networking, it is considered PaaS
What is SaaS and what does it do?
Software as a service cloud system
The software is licensed to customers with subscriptions and central hosting.
What are some examples of SaaS cloud systems?
3
- Gmail
- Google Docs
- Microsoft Office 365
What is ERP
Stores system and sales records, finance, enterprise resource planning.
Good Data enables businesses to: (7)
- Analyze current financial state of the organization in terms of net profits, revenues, cash flow, assets and liabilities
- Increase revenue through better targeting of products and increased customer satisfaction.
- Examine existing production processes to take corrective action, improve efficiency, and lower costs.
- Develop new, automated, processes that integrate harmoniously into existing workflows and reduce demands on labor
- Gather competitive information on produc and pricing decisions to stay ahead of competitors
- Make evidence-based decisions that utilize verifiable data to maximize profits and efficiency
- Understand business value by exploiting rapid changes in information and generating insights from diverse data sources to widen the competitive differentiation gap
What are 3 general steps for transforming institutional knowledge into implantable data solutions:
- Capturing
- Analyzing
- Using
What is data hygiene?
Refers to the processes of ensuring the cleanliness of data (ie that the data is relatively error-free)
What can cause dirty data? (3)
- Duplicate Records
- Incomplete or Outdated Data
- Mistakes introduced as data is entered stored and managed
What is data scrubbing?
The process of amending or removing data in a database that is incorrect, incomplete, improperly formatted, or duplicated.
What does the process of data scrubbing usually involve?
Updating, standardizing, and de-duplicating records to create a single view of the data even if it is stored in multiple systems.
What is duplicate Data
Two or more identical records
What is conflicting data?
The same records with differing attributes
What is incomplete data
Missing attributes
What is invalid data?
Attributes not conforming to standardization
What is unsynchronized data
Data that is not appropriately shared between two systems.
What is quality data
Data that is precise, valid, reliable, timely, and complete.
Data is complete and thorough
When is quality data valid
When it meets requirements of the data collection process.
What are some examples of input?
Raw data entered by a user or acquired from a data source

What is the motherboard?
(Add Clarifier)
Add Footnote
A
The motherboard is at the center of what makes a computer work. It houses the CPU and serves as the brain of the system. It allocates resources such as power and communicates with all other components.
What is a CPU
Central Proccessing unit. Processes the data from the programs the computer runs.
What is RAM
Random-access memory. Occupies the memory slots of the CPU and keeps that data immediately accessible.
What is a hard Drive?
Storage device that permanently stores data or temporarily stores data in a paging file system.
What is a computers paging feature and which component does it work closely with?
The paging feature is a built-in mechanism that permits data to be moved from the RAM to the Hard Drive when the amount of memory in use exceeds the memory available in the computer system.
What are the two common types of networks?
LAN and WANS
What are LANs
Local area networks
LANs span a single home, school, or office building and provide a connection for devices that are within the same network
