The document outlines the key concepts of distributed database management systems (DDBMS). It defines a DDBMS as a collection of logically interrelated databases distributed over a computer network and managed by a software system that makes the distribution transparent to users. The document discusses the motivation for DDBMS, their promises around transparent access and improved reliability, performance and scalability. It also covers important concepts like data distribution, query processing, concurrency control and transaction management that DDBMS must address.

The Evolution of Distributed Database
Management Systems
• Distributed database management system
(DDBMS)
– Governs storage and processing of logically related
data over interconnected computer systems
– Both data and processing functions are distributed
among several sites
• 1970s - Centralized database required that
corporate data be stored in a single central site
– Usually a mainframe computer
– Data access via dumb terminals
Database Systems, 10th Edition 2
Database Systems, 10th Edition 3
• Wasn’t responsive to need for faster response times
and quick access to information
• Slow process to approve and develop new application
The Evolution of Distributed Database
Management Systems
Database Systems, 10th Edition 4
• Social and technological changes led to change
• Businesses went global; competition was now in
cyberspace not next door
• Customer demands and market needs required Web-
based services
• rapid development of low-cost, smart mobile devices
increased the demand for complex and fast networks to
interconnect them – cloud based services
• Multiple types of data (voice, image, video, music)
which are geographically distributed must be managed
The Evolution of Distributed Database
Management Systems
Database Systems, 10th Edition 5
• As a result, businesses had to react quickly to
remain competitive. This required:
• Rapid ad hoc data access became crucial in
the quick-response decision making
environment
• Distributed data access to support
geographically dispersed business units
The Evolution of Distributed Database
Management Systems
Database Systems, 10th Edition 6
• The following factors strongly influenced the shape of the
response
• Acceptance of the Internet as the platform for data access
and distribution
• The mobile wireless revolution
• Created high demand for data access
• Use of “applications as a service”
• Company data stored on central servers but applications are
deployed “in the cloud”
• Increased focus on mobile BI
• Use of social networks increases need for on-the-spot
decision making
The Evolution of Distributed Database
Management Systems
Database Systems, 10th Edition 7
• The distributed database is especially desirable because
centralized database management is subject to problems such
as:
• Performance degradation as remote locations and distances
increase
• High cost to maintain and operate
• Reliability issues with a single site and need for data
replication
• Scalability problems due to a single location (space, power
consumption, etc)
• Organizational rigidity imposed by the database – might not
be able to support flexibility and agility required by modern
global organizations

Cloud-Native Data: What data questions to ask when building cloud-native appsVMware Tanzu
While a number of patterns and architectural guidelines exist for cloud-native applications, a discussion about data often leads to more questions than answers. For example, what are some of the typical data problems encountered, why are they different, and how can they be overcome?
Join Prasad Radhakrishnan from Pivotal and Dave Nielsen from Redis Labs as they discuss:
- Expectations and requirements of cloud-native data
- Common faux pas and strategies on how you can avoid them

Understanding Inductive Bias in Machine LearningSUTEJAS
This presentation explores the concept of inductive bias in machine learning. It explains how algorithms come with built-in assumptions and preferences that guide the learning process. You'll learn about the different types of inductive bias and how they can impact the performance and generalizability of machine learning models.
The presentation also covers the positive and negative aspects of inductive bias, along with strategies for mitigating potential drawbacks. We'll explore examples of how bias manifests in algorithms like neural networks and decision trees.
By understanding inductive bias, you can gain valuable insights into how machine learning models work and make informed decisions when building and deploying them.
Low power architecture of logic gates using adiabatic techniquesnooriasukmaningtyas
The growing significance of portable systems to limit power consumption in ultra-large-scale-integration chips of very high density, has recently led to rapid and inventive progresses in low-power design. The most effective technique is adiabatic logic circuit design in energy-efficient hardware. This paper presents two adiabatic approaches for the design of low power circuits, modified positive feedback adiabatic logic (modified PFAL) and the other is direct current diode based positive feedback adiabatic logic (DC-DB PFAL). Logic gates are the preliminary components in any digital circuit design. By improving the performance of basic gates, one can improvise the whole system performance. In this paper proposed circuit design of the low power architecture of OR/NOR, AND/NAND, and XOR/XNOR gates are presented using the said approaches and their results are analyzed for powerdissipation, delay, power-delay-product and rise time and compared with the other adiabatic techniques along with the conventional complementary metal oxide semiconductor (CMOS) designs reported in the literature. It has been found that the designs with DC-DB PFAL technique outperform with the percentage improvement of 65% for NOR gate and 7% for NAND gate and 34% for XNOR gate over the modified PFAL techniques at 10 MHz respectively.

Harnessing WebAssembly for Real-time Stateless Streaming PipelinesChristina Lin
Traditionally, dealing with real-time data pipelines has involved significant overhead, even for straightforward tasks like data transformation or masking. However, in this talk, we’ll venture into the dynamic realm of WebAssembly (WASM) and discover how it can revolutionize the creation of stateless streaming pipelines within a Kafka (Redpanda) broker. These pipelines are adept at managing low-latency, high-data-volume scenarios.

Water billing management system project report.pdfKamal Acharya
Our project entitled “Water Billing Management System” aims is to generate Water bill with all the charges and penalty. Manual system that is employed is extremely laborious and quite inadequate. It only makes the process more difficult and hard.
The aim of our project is to develop a system that is meant to partially computerize the work performed in the Water Board like generating monthly Water bill, record of consuming unit of water, store record of the customer and previous unpaid record.
We used HTML/PHP as front end and MYSQL as back end for developing our project. HTML is primarily a visual design environment.

A review on techniques and modelling methodologies used for checking electrom...nooriasukmaningtyas
The proper function of the integrated circuit (IC) in an inhibiting electromagnetic environment has always been a serious concern throughout the decades of revolution in the world of electronics, from disjunct devices to today’s integrated circuit technology, where billions of transistors are combined on a single chip. The automotive industry and smart vehicles in particular, are confronting design issues such as being prone to electromagnetic interference (EMI). Electronic control devices calculate incorrect outputs because of EMI and sensors give misleading values which can prove fatal in case of automotives. In this paper, the authors have non exhaustively tried to review research work concerned with the investigation of EMI in ICs and prediction of this EMI using various modelling methodologies and measurement setups.
