lectures week 1

Question 1

why should we use programming languages and not using excel for data analysis?

Answer 1

1. Scalability and performance
   what if data is not in megabytes but petabytes
2. Automation and reproducibility
   What if data comes in regularly
3. Advanced analytical capabilities
   What if we want to do a network analysis
4. better integration with many other tools
   what if we want to connect to SQL databases, API’s

Question 2

syntax

Answer 2

Question 4

Answer 5

focuses on using python (typing errors etc).

Question 6

prototyping

Answer 6

Instead of building the entire software in one go, prototypes (early, incomplete versions of the software) are created first.
Customers can see and test these prototypes early and give feedback.
Developers can then make changes before creating the final product.

Question 7

incremental

Answer 7

Incremental: you have a finished part of software, but it doesn’t include all the requirements, but the part that you have is already finished.

Question 8

iterative

Answer 8

you have all the game elements, but don’t have the complete functionality yet.

Question 9

Rational Unified Process

Answer 9

An iterative software development process framework created by the Rational Software Corporation (IBM). Not a concrete prescriptive process, but an adaptable framework, intended to be tailored by the development organizations. Expected to select elements of the process that are appropriate

Question 10

RAD

Answer 10

RAD is all about building software quickly with continuous user feedback.
Instead of spending a long time on planning and documentation (like the Waterfall model), RAD rapidly creates working prototypes.
It involves frequent updates and changes based on user input.
