This document discusses different software architecture tiers - 1-tier, 2-tier, and 3-tier architectures. 1-tier architecture has all components tightly coupled together with no separation. 2-tier architecture separates components into client and server but business logic remains coupled to either presentation or data. 3-tier architecture fully separates presentation, business logic, and data layers, allowing each tier to scale independently for improved performance, reusability, and maintainability compared to 1-tier and 2-tier architectures.
This document discusses 3-tier architecture. It explains that a 3-tier architecture separates a system into presentation tier (user interface), logic tier (business logic), and data tier (database). An example is given of a supermarket customer management system. Advantages of 3-tier include scalability, flexibility, and the ability to independently manage each tier. Disadvantages include more complex setup and maintenance compared to 1-tier and 2-tier architectures. The document provides an overview of 1-tier and 2-tier architectures for comparison. It encourages learning more about programming through online courses offered by the organization.
This document presents an overview of 3-tier architecture. It introduces software components and the different tiers of architecture. The 3 tiers are the presentation layer, application layer, and resource management layer. The presentation layer handles the user interface, the application layer contains business logic and calculations, and the resource management layer deals with different data sources and is implemented using a database management system. Advantages of 3-tier architecture include scalability and flexibility, while disadvantages include potential performance losses when distributed over the internet and costs associated with integrating different 3-tier systems.
This document discusses the evolution of application architectures from single-tier to multi-tier structures. It begins by describing single-tier architecture as having all application components on one machine, making it simple but insecure. Two-tier architecture separates the database onto a server for increased security but clients still handle business logic. Three-tier architecture introduces a middle business logic layer, keeping clients "thinner" for faster performance at scale. It provides an example of how ASP.NET applications can be organized into presentation, business and data access layers.
The document discusses 3-tier architecture, which separates an application into three logical layers - the presentation layer, business logic layer, and data layer. It describes how this architecture evolved from earlier single-tier and dual-tier models. The 3-tier model provides advantages like scalability, reusability, security, and availability. While more complex than 2-tier, it allows for improved performance in medium to large systems by distributing the application across servers. An example is provided of implementing a 3-tier application using ASP.NET with distinct presentation, business, and data access layers.
This document discusses 3-tier architecture, which divides applications into presentation, application, and data tiers. The presentation tier handles the user interface, the application tier contains business logic, and the data tier stores information in a database. 3-tier architecture provides benefits like scalability, improved security, reduced distribution complexity, and maintainability. However, it also increases complexity compared to 2-tier systems. The document uses web and mobile applications as common examples of 3-tier architectures and explains how each tier is separated but communicates through standard interfaces.
A 3-tier architecture separates an application into three logical tiers - the presentation tier, the application tier, and the data tier. The presentation tier displays information to the user and communicates with other tiers. The application tier contains most of the logic and communicates between the other tiers. The data tier manages the database where information is stored and retrieved independently from the other tiers. This separation of concerns allows each tier to be updated or modified without impacting the others.

- What thin client computing is and how it stores applications and data on central servers rather than individual client devices, reducing costs and management needs.
- The key components of thin client solutions including terminal servers, thin clients, and communication protocols.
- How thin clients operate by connecting to terminal servers and only receiving screen updates rather than processing information locally.
Client/Server Architecture By Faisal Shahzad Faisal Shehzad
The document discusses client-server architectures. It describes the fat server model, which places more functions on the server, and the fat client model, which places more functions on the client but stores data on the server. It then explains the key aspects of two-tier and three-tier client-server architectures. The two-tier architecture involves clients communicating directly with servers, while the three-tier architecture introduces a middle tier between clients and servers to improve performance, scalability, and other advantages.
The document discusses different architectures for client/server systems. A client/server architecture separates computers into clients and servers, with servers providing resources like files, printers or network traffic. A two-tier architecture has clients communicating with a database server, while a three-tier architecture separates the user interface, application logic and data storage into distinct tiers or layers.
Client-server technology involves splitting tasks and computing power between servers and clients. Servers store and process common data that can be accessed by clients. Clients make requests to servers, which then process the requests and return the desired results. This architecture is versatile, supports GUIs, and reduces costs through technologies like relational databases and distributed computing. The document then discusses the evolution of client-server computing and different types of client-server architectures like thin/fat, stateless/stateful, two-tier/three-tier/n-tier architectures. It also covers client and server devices and developing client-server applications.
discussions about different types of architectures used in web applications, pros and cons of each architecture. MVC design patters and comparison with 3-tier.
The document discusses different client-server architectures, including two-tiered and three-tiered architectures. It provides details on the components, usage considerations, benefits, and limitations of the two-tiered architecture. The three-tiered architecture adds a middle tier to address scalability and flexibility limitations of the two-tiered approach. Various implementations of the middle tier are examined, including transaction processing monitors, message servers, and application servers.
The document discusses the evolution of client-server architectures from centralized systems to modern multi-tier architectures. Early centralized systems had all components on a single mainframe computer, while file server architectures moved application logic to clients but kept data on a central file server. Client-server systems partitioned applications into separate client and server components communicating over a network. Modern architectures further separate concerns into multiple logical tiers or services for improved performance, manageability, and reuse across applications.
The document describes client-server and peer-to-peer architecture styles. Client-server architecture divides an application into two parts - the client and the server. The client makes requests to the server which processes requests and returns results. Common client-server structures include 2-tier with a database server and client, and 3-tier with an additional middle tier. Peer-to-peer architecture has no servers or clients - each node can request and provide services to other nodes on the network.
Anil Nembang: Hures Company Case StudyAnil Nembang
The document discusses the client-server architecture used by Hures Company and alternatives to address its problems. It describes how Hures initially used a mainframe computer with dumb terminals, then ported to a client-server system, which faced scalability issues. A three-tier architecture is proposed to solve these problems by separating the presentation, logic, and data tiers. Intranet technology is also examined, which could enable greater information sharing but has costs. Overall, intranets and the internet pose a threat to traditional client-server systems due to advantages of three-tier architectures used by these technologies.
The document discusses different application architectures: single-tier, two-tier, three-tier, and n-tier. In a single-tier architecture, all application elements exist in a single process. A two-tier architecture divides the application into client and server tiers. A three-tier architecture adds a business tier between the client and server tiers. An n-tier architecture further divides business services into multiple manageable units across multiple tiers.
This document discusses client-server architecture. It defines clients as workstations that rely on servers for resources like files, devices, and processing power. Servers are dedicated computers that manage disk drives, printers, or network traffic. In a client-server model, applications are split into client and server components, with clients accessing services provided by servers. There are two main types: 2-tier, with clients and a single server, and 3-tier, with separate servers for the interface, logic, and data layers, allowing for better scalability. Thin clients rely fully on servers, while fat clients run some application logic locally.

The document discusses the design of a two-pass macro preprocessor. In pass one, macro definitions are identified and stored in a macro definition table along with their parameters. A macro name table is also created. In pass two, macro calls are identified and replaced by retrieving the corresponding macro definition and substituting actual parameters for formal parameters using an argument list array. Databases like the macro definition table, macro name table, and argument list array are used to store and retrieve macro information to enable expansion of macro calls. The algorithm scans the input sequentially in each pass to process macro definitions and calls.

Why Psychological Safety Matters for Software Teams - ACE 2024 - Ben Linders.pdfBen Linders
Psychological safety in teams is important; team members must feel safe and able to communicate and collaborate effectively to deliver value. It’s also necessary to build long-lasting teams since things will happen and relationships will be strained.
But, how safe is a team? How can we determine if there are any factors that make the team unsafe or have an impact on the team’s culture?
In this mini-workshop, we’ll play games for psychological safety and team culture utilizing a deck of coaching cards, The Psychological Safety Cards. We will learn how to use gamification to gain a better understanding of what’s going on in teams. Individuals share what they have learned from working in teams, what has impacted the team’s safety and culture, and what has led to positive change.
Different game formats will be played in groups in parallel. Examples are an ice-breaker to get people talking about psychological safety, a constellation where people take positions about aspects of psychological safety in their team or organization, and collaborative card games where people work together to create an environment that fosters psychological safety.

Gamify it until you make it Improving Agile Development and Operations with ...Ben Linders
So many challenges, so little time. While we’re busy developing software and keeping it operational, we also need to sharpen the saw, but how? Gamification can be a way to look at how you’re doing and find out where to improve. It’s a great way to have everyone involved and get the best out of people.
In this presentation, Ben Linders will show how playing games with the DevOps coaching cards can help to explore your current development and deployment (DevOps) practices and decide as a team what to improve or experiment with.
The games that we play are based on an engagement model. Instead of imposing change, the games enable people to pull in ideas for change and apply those in a way that best suits their collective needs.
By playing games, you can learn from each other. Teams can use games, exercises, and coaching cards to discuss values, principles, and practices, and share their experiences and learnings.
Different game formats can be used to share experiences on DevOps principles and practices and explore how they can be applied effectively. This presentation provides an overview of playing formats and will inspire you to come up with your own formats.

1.) Introduction
Our Movement is not new; it is the same as it was for Freedom, Justice, and Equality since we were labeled as slaves. However, this movement at its core must entail economics.
2.) Historical Context
This is the same movement because none of the previous movements, such as boycotts, were ever completed. For some, maybe, but for the most part, it’s just a place to keep your stable until you’re ready to assimilate them into your system. The rest of the crabs are left in the world’s worst parts, begging for scraps.
3.) Economic Empowerment
Our Movement aims to show that it is indeed possible for the less fortunate to establish their economic system. Everyone else – Caucasian, Asian, Mexican, Israeli, Jews, etc. – has their systems, and they all set up and usurp money from the less fortunate. So, the less fortunate buy from every one of them, yet none of them buy from the less fortunate. Moreover, the less fortunate really don’t have anything to sell.
4.) Collaboration with Organizations
Our Movement will demonstrate how organizations such as the National Association for the Advancement of Colored People, National Urban League, Black Lives Matter, and others can assist in creating a much more indestructible Black Wall Street.
5.) Vision for the Future
Our Movement will not settle for less than those who came before us and stopped before the rights were equal. The economy, jobs, healthcare, education, housing, incarceration – everything is unfair, and what isn’t is rigged for the less fortunate to fail, as evidenced in society.
6.) Call to Action
Our movement has started and implemented everything needed for the advancement of the economic system. There are positions for only those who understand the importance of this movement, as failure to address it will continue the degradation of the people deemed less fortunate.
No, this isn’t Noah’s Ark, nor am I a Prophet. I’m just a man who wrote a couple of books, created a magnificent website: http://www.thearkproject.llc, and who truly hopes to try and initiate a truly sustainable economic system for deprived people. We may not all have the same beliefs, but if our methods are tried, tested, and proven, we can come together and help others. My website: http://www.thearkproject.llc is very informative and considerably controversial. Please check it out, and if you are afraid, leave immediately; it’s no place for cowards. The last Prophet said: “Whoever among you sees an evil action, then let him change it with his hand [by taking action]; if he cannot, then with his tongue [by speaking out]; and if he cannot, then, with his heart – and that is the weakest of faith.” [Sahih Muslim] If we all, or even some of us, did this, there would be significant change. We are able to witness it on small and grand scales, for example, from climate control to business partnerships. I encourage, invite, and challenge you all to support me by visiting my website.

Overview of 3-tier Client Server Architecture

TECHNOLOGY, MESRA

TOPIC :OVERVIEW OF 3-TIER CLIENT
SERVER ARCHITECTURE
2. 3-TIER ARCHITECTURE
A three-way interaction in a client/server environment
where :
User interface is stored in the client.
Bulk of the business aplication logic is stored in one
or more servers.
data are stored in a database server.
5. 3-TIER ARCHITECTURE
With the advent of Internet many people jumped to
the conclusion that the days of the mainframe were
back.
Client/Server obviously failed, personal computers
had failed and Windows was on its way out.
A host of “thin client” application where developed.
Thus 3-tier applications were born
6. This Application runs the traditional client / server
model but from a web server.
7. The client only displays the GUI and data , but has
no part in producing results.
8. BENEFITS
SCALABILITY:
The application servers can be deployed on many
machines.
The database no longer requires a connection from
every client (only from a smaller number of
application servers).
TP monitors or ORBs can be used to balance loads
and dynamically manage the number of application
server(s) available.
9. BENEFITS
BETTER RE-USE:
If an estandard object is employed, the specific
language of implementation of the middle tier can
be made transparent.
IMPROVE DATA INTEGRITY:
The middle tier can ensure that only valid data is
allowed to be updated in the database.
10. BENEFITS
IMPROVED SECURITY:
Since the client doesn’t have direct access to the
database.
Business Logic is generally more secure since it is
placed on a more secure central server.
REDUCED DISTRIBUTION:
Changes to business logic only need to be updated
on the application servers and do not have to be
distributed to all the clients.
11. BENEFITS
IMPROVED AVAILABILITY:
Mission-critical applications can make use of
redundant application servers and redundant
database servers, so it can recover from network or
server failures.
HIDDEN DATABASE STRUCTURE :
Since the actual structure of the database is hidden
from the caller.
12. DRAWBACKS
INCREASED COMPLEXITY/EFFORT:
In general is more difficult to build a 3-tier
application compared a 2-tier application because:
The points of communication are doubled.
Many handy productivity enhacements provided by
the client tools will be foregone or their benefit will be
reduced.
FEWER TOOLS:
The existence of more tools available for a 2-tier
model (e.g. most reporting tools).
13. ADVANTAGES OF THE 3-TIER ARCHITECTURE
APPROACH :
o the ability to separate logical components of an
application ensures that applications are easy to
manage and understand.
i.e. experts can be employed that specialise in one of
the layers e.g. user interface design
o because communication can be controlled between
each logical tier of an application, changes in one tier,
for example, the database access tier, do not have to
affect the client component
i.e. a change from one DBMS to another would only
require a change to the component in the data access
layer with little or no effect on the business/logic (middle)
or UI layer.
o specific tools and technologies suited to each layer
can be deployed (and may evolve at a different pace) .
14. CONCLUSION
Complex application rules easy to implement in
application server.
Business logic off-loaded from database server and
client, which improve performance .
Changes to business logic automatically enforce by
server .
Application server is portable to other database
server platforms by virtue of the application SW.
Superior performance for medium to high volume
environments
