0

I’ve been learning strings on Zybooks before my MSBA program next year at UofL.

Here is the problem:

An acronym is a word formed from the initial letters of words in a set phrase. Write a program whose input is a phrase and whose output is an acronym of the input. If a word begins with a lower case letter, don’t include that letter in the acronym. Assume there will be at least one upper case letter in the input.

1Why Databases?

Because databases make data persistent and shareable in a secure way, they are the best way to store, manage, and retrieve data very quickly.

Data: Raw facts, or facts that have not yet been processed to reveal their meaning the the end user.

Information = The result of processing raw data to reveal its meaning and facilitate decision making.

knowledge = The body of info and facts about a specific subject.

metadata = Data about data; data about data characteristics and relationships.

ad hoc query= a ‘spur-of-the-moment” question.

Types of Databases:
Single-user, desktop, multi-user, workgroup, enterprise, centralized, distributed, cloud, general-purpose, discipline-specific, and operational database.
