Product Design Trends in 2024 | Teenage EngineeringsPixeldarts
The realm of product design is a constantly changing environment where technology and style intersect. Every year introduces fresh challenges and exciting trends that mold the future of this captivating art form. In this piece, we delve into the significant trends set to influence the look and functionality of product design in the year 2024.
How Race, Age and Gender Shape Attitudes Towards Mental HealthThinkNow
Mental health has been in the news quite a bit lately. Dozens of U.S. states are currently suing Meta for contributing to the youth mental health crisis by inserting addictive features into their products, while the U.S. Surgeon General is touring the nation to bring awareness to the growing epidemic of loneliness and isolation. The country has endured periods of low national morale, such as in the 1970s when high inflation and the energy crisis worsened public sentiment following the Vietnam War. The current mood, however, feels different. Gallup recently reported that national mental health is at an all-time low, with few bright spots to lift spirits.
To better understand how Americans are feeling and their attitudes towards mental health in general, ThinkNow conducted a nationally representative quantitative survey of 1,500 respondents and found some interesting differences among ethnic, age and gender groups.
Technology
For example, 52% agree that technology and social media have a negative impact on mental health, but when broken out by race, 61% of Whites felt technology had a negative effect, and only 48% of Hispanics thought it did.
While technology has helped us keep in touch with friends and family in faraway places, it appears to have degraded our ability to connect in person. Staying connected online is a double-edged sword since the same news feed that brings us pictures of the grandkids and fluffy kittens also feeds us news about the wars in Israel and Ukraine, the dysfunction in Washington, the latest mass shooting and the climate crisis.
Hispanics may have a built-in defense against the isolation technology breeds, owing to their large, multigenerational households, strong social support systems, and tendency to use social media to stay connected with relatives abroad.
Age and Gender
When asked how individuals rate their mental health, men rate it higher than women by 11 percentage points, and Baby Boomers rank it highest at 83%, saying it’s good or excellent vs. 57% of Gen Z saying the same.
Gen Z spends the most amount of time on social media, so the notion that social media negatively affects mental health appears to be correlated. Unfortunately, Gen Z is also the generation that’s least comfortable discussing mental health concerns with healthcare professionals. Only 40% of them state they’re comfortable discussing their issues with a professional compared to 60% of Millennials and 65% of Boomers.
Race Affects Attitudes
As seen in previous research conducted by ThinkNow, Asian Americans lag other groups when it comes to awareness of mental health issues. Twenty-four percent of Asian Americans believe that having a mental health issue is a sign of weakness compared to the 16% average for all groups. Asians are also considerably less likely to be aware of mental health services in their communities (42% vs. 55%) and most likely to seek out information on social media (51% vs. 35%).

Is Hotel Booking LLD as Simple as in the Applications (1).pdf
1. Is Hotel Booking LLD as Simple as in the
Applications?
import Image from "next/img";
You must wonder how the hotel booking applications work. How does
the hotel booking application design finds us the best options after comparing
every competing hotel room prices & offers and provide us with the best
results? After all, what happens in the back end of such square hotel booking
system design applications? There are several hotel reservation systems such
2. as OYO, Trivago, Hotels.com, and several more websites and applications
which consider various aspects of the System Design hotel reservation
system we might be familiar with. There are several tasks that need to be
carried out by these high-level system design and hotel reservation systems
like price comparison, booking required rooms, availability, ratings, payment,
etc. which are finely designed to go hand in hand along with hotel booking
low-level designs for every sub-system.
First, let us know what an LLD is. Low-level design (LLD) is an internal
component level logical design process that can be utilized for designing data
structures, performance algorithms, source code, and the necessary software
architecture through a step by step refinement procedure. Now it can be
clearly understood as to why we should be knowing about the working of LLD.
Let us now analyze the challenges for this LLD and how these hotel booking
low-level designs of such particular systems are created.
Planning and Sorting out The Skeleton
Let us consider the task of the reservation of a room for a particular system. A
popular design pattern that is deployed for such applications is Object
Relational Mapping (ORM) which is a class structure used on the basis of how
we have used the database structure. This pattern favors rationality between
the data and the design. We require to understand the database schema to
proceed further with either LLD or DLD. Also, we need to consider the
following database tables: ● Guests (which can only be booked when the user
is booking the same) ● Room (the particular type of room the user chooses to
book)
● Hotel (the rooms should belong to a respective hotel)
● Reservation (the reservations need to be tracked down and stored as well)
● Payment, that can be made through several modes or in certain ways like
partial, complete, or, with or without an advance.
Let us now see what each of these fields should have in them as their
elements and make a database using SQL as we need to store all the
information in a tabular form for our benefits of finding the information in an
organised way. Later, you can find that somehow all fields are interconnected
to each other through either one or many of each of their elements.
1. User or Guest:
3. If we dig into the details of the "user" database description, we would find
various details under the name user_id, like first name, last name, location,
and phone number each of which corresponds to a certain data type.
fig. 1
2. Room:
Similarly, we have the room database which can be classified as per the room
type or its capacity along with the facilities it consists of, like heater, wifi, air
conditioner, etc. It can also hold information like if the room is sea facing, or
has a hilltop view, etc.
fig. 2
4. 3. Hotel:
Then the hotel database can consist of its location and the owner's details. It
needs to have a list of the type of rooms the hotel consists of and it needs to
make sure the rooms belong to their respective hotels and also store the
information of the rooms which are booked or occupied or unreserved. fig.
3 ###4. Reservation:
Further, the reservation database would be a combination of the information
entered by the user mentioning check-in and check-out timings and payment
details, and also the room type. Designing a checklist for all the payment
transactions can be done by following the normalization rule for SQL as it has
to be associated with the revervation_id so that all the transactions made by
the user come under this domain. ** fig. 4**
5. Transaction:
For all the payment transactions done by the user is now to be stored along
with the amount linked to the transaction_id. This should also store the type of
method used for payment by the user be it cash, card, UPI, etc. or if there is
any offer or coupon code applicable with the terms and conditions. fig. 5
6. Payment:
5. For this to be recorded appropriately, each tuple is required to make a
connection between booking_id with the analogous transaction_id. fig. 6
Square Hotel Booking System Design
We can make a hotel management system project design decision to hold the
transaction updates in the form of a list or a separate table linked with the
reservation database with multiple tuples for each payment transaction. The
separate table linked with the reservation database is an application of
the Normalization rule for SQL though the list way reduces the additional
query processing. It is preferable to use the tabular method. The transaction
table holds the information about the amount being transferred. Lastly, the
payment database connects the payments made with the associated
transaction as mentioned above. The application can be made further user-
friendly by accepting cancellations depending on certain terms and conditions.
The flowchart represented in the figure below is to be noted with the help of
the following schema:
● reservation -> user (1:1)
● room -> hotel (many:1)
● reservation -> payment (1: many)
● payment -> transaction (1:1)
● reservation -> room (1: many)
● reservation -> hotel (1:1)
● reservation -> room type (1: many)
● reservation -> room type rooms (1:1)
fig. 7
Hotel Booking Program in Java
6. If we wish to prepare an Object Oriented Programming design for an
online hotel booking program in Java, one needs to create certain classes and
attributes which would hold information with the corresponding datatype.
● We shall introduce a class ‘user’ which shall hold the user's Information like
user_id, name, date of birth, mobile number, email ID, gender and other such
personal information.
● Then there would be a class ‘Room’ that shall hold information like the
room_id, hotel_id, room's type and availability.
● Then the class ‘hotel’ shall hold information like the list of rooms, address,
facilities provided and other such information regarding the hotel.
● Further, the ‘booking’ class would hold information about the user, the hotel,
list of rooms, payment status, and booking time and duration.
● The class ‘address’ would hold the address of the hotel.
● Lastly, there shall be a class ‘duration’ to hold information about the time of
stay required for the booking.
Each of these classes shall hold the data with the specified data types which
can be manipulated as per the response demanded from the user's end. The
access should also be given to the manager or any other higher or reserved
authority so that the hotel information can be updated like prices, more
pictures, or facilities. This is just a basic algorithm for the application, on
desired, more elements can be added and linked to make it as user-friendly
as possible.
Conclusion
The above article portrays what happens at the backend of any hotel booking
application. Everything here is done to make a website or application as
appealing as possible. We discussed the challenges and necessities to be
kept in mind for the system LLD, then a skeleton to plan an application out,
and lastly a Java algorithm to give the application a complete outlook.
Whether or not you belong to the Computer Science field, you must know
these trends and updates such as LLD applications and Java. For deeper
learning or if you want to express your ideas in a canvas of application you
could refer to Skillslash courses like Full Stack Development Course In
7. Bangalore and Data Science Course In Pune with placement, workshops to
stay updated and broaden your horizon of thinking and implementing.
