This document discusses transparency in distributed database management systems (DDBMS). It defines transparency as hiding the internal details of data distribution from users. There are three main aspects of transparency: location transparency ensures users see a uniform namespace regardless of where data is located; fragmentation transparency hides how data is fragmented across sites from users; and replication transparency ensures users cannot tell if data came from a replicated copy or the original. The document provides details on each type of transparency and emphasizes that transparency aims to make the distributed system as easy to use as a centralized one for users.

A Comprehensive Study On Data Mining Process With Distribution
This document discusses combining data mining processes with distribution. It proposes an architecture that involves gathering data from various sources, distributing it over a network using cloud computing, and allowing various types of users to query the data using DMQL. A converter is needed to transform queries to the appropriate format for mining. Combining distribution with mining provides benefits like accessing data from multiple sources and serving different user levels, but also introduces complexities in locating data and transforming formats.

Implementation of Agent Based Dynamic Distributed Service
This document proposes a design for agent migration between distributed systems using ACL (Agent Communication Language) messages. It involves serializing an agent's code and state into an ACL message that is sent from one system to another. The receiving system deserializes the agent to restore its execution. The design includes defining an ontology for migration messages, a migration protocol specifying the message flow, and components for handling class loading, agent migration, and conversation protocols. The performance of this distributed agent migration approach is evaluated by applying it to a distributed prime number calculation application.

This document summarizes a research paper that proposes a scheme for ensuring security and reliability of data stored in the cloud. The scheme utilizes erasure coding to redundantly store encrypted data fragments across multiple cloud servers. It generates homomorphic tokens that allow auditing of the data storage and identification of any misbehaving servers. The scheme supports secure dynamic operations like modification, deletion and append of cloud data files. Analysis shows the scheme is efficient and resilient against various security threats like server compromises or failures. It ensures storage correctness and fast localization of data errors in the cloud.
Chapter-6 Distribute Database system (3).ppt
A distributed database management system (DDBMS) governs logically related data distributed across interconnected computer systems. A DDBMS manages a distributed database while making the distribution transparent to users. Distributed databases provide advantages like improved performance through storing data closer to where it is needed, easier expansion, and increased reliability through redundancy. However, distributed databases also introduce challenges around increased complexity, lack of standards, and security concerns.
IRJET - Identifying Information Relocate with Reliable Estimation and Sec...
This document summarizes a research paper that proposes a method for ensuring data integrity and privacy when data is stored on cloud computing systems. The method uses blockchain techniques and distributed verification to provide redundancy and guarantee data reliability. It allows both data owners and public verifiers to check data integrity without downloading the entire dataset. The technique utilizes homomorphic tokens and ring signatures to enable auditing while preventing privacy leaks about user identities or data contents. Prior works on remote data integrity lacked either public auditing or support for dynamic data operations, but the proposed method achieves both.

Santosh Kumar Meher(2105040008) DISTRIBUTED DATABASE.pptx
Distributed database consists of multiple databases that are connected with each other and are spread across different physical locations. The data that is stored on various physical locations can thus be managed independently of other physical locations. The communication between databases at different physical locations is thus done by a computer network.
A distributed database is a database that is not limited to one computer system.
It is like a database that consists of two or more files located in different computers or sites either on the same network or on an entirely different network.
Instead of storing all of the data in one database, data is divided and stored at different locations or sites which do not share any physical component.
The data can be easily accessed, managed, modified, updated, controlled, and organized in a database.
Lecture03.pptx
This document discusses the concepts of distributed systems and virtualization, including definitions of distributed systems, their characteristics and advantages/disadvantages.

The document summarizes research on vertical fragmentation, allocation, and re-fragmentation in distributed object relational database systems. It proposes an algorithm for vertical fragmentation and allocation that considers the usage of attributes and methods by queries at different sites. The algorithm forms usage matrices, calculates affinity between methods, clusters methods, and partitions the data into fragments that are allocated to sites where they see the most demand. It also describes handling update queries by redirecting them to a server for processing and then propagating the updates to relevant fragments.
IRJET - Health Medicare Data using Tweets in Twitter
This document describes a proposed system to analyze health-related tweets from Twitter. The system would extract tweets using Twitter APIs, preprocess the tweets by removing stop words and replacing emojis and slang with standard words. The preprocessed tweets would then be classified using a support vector machine model to categorize them based on discussed health topics and diseases. The system would generate reports showing the number of tweets in different countries discussing specific diseases, to help predict where disease outbreaks may occur. The proposed system aims to provide real-time health insights from social media data on Twitter.
Paper2
1. The document proposes a system for secure user authentication and access control for encrypted data stored in the cloud. It aims to address issues with centralized access control and storing data in plaintext.
2. The proposed system uses a key distribution center to generate public, private, and access keys for authentication at different levels. Data is encrypted before being fragmented and distributed across multiple servers.
3. Only authorized users with proper keys can decrypt the data. Access policies set by data creators restrict which users can access files. Storing encrypted and distributed data along with key-based authentication aims to improve security over existing cloud storage systems.

End-to-end pipeline agility - Berlin Buzzwords 2024
We describe how we achieve high change agility in data engineering by eliminating the fear of breaking downstream data pipelines through end-to-end pipeline testing, and by using schema metaprogramming to safely eliminate boilerplate involved in changes that affect whole pipelines.
A quick poll on agility in changing pipelines from end to end indicated a huge span in capabilities. For the question "How long time does it take for all downstream pipelines to be adapted to an upstream change," the median response was 6 months, but some respondents could do it in less than a day. When quantitative data engineering differences between the best and worst are measured, the span is often 100x-1000x, sometimes even more.
A long time ago, we suffered at Spotify from fear of changing pipelines due to not knowing what the impact might be downstream. We made plans for a technical solution to test pipelines end-to-end to mitigate that fear, but the effort failed for cultural reasons. We eventually solved this challenge, but in a different context. In this presentation we will describe how we test full pipelines effectively by manipulating workflow orchestration, which enables us to make changes in pipelines without fear of breaking downstream.
Making schema changes that affect many jobs also involves a lot of toil and boilerplate. Using schema-on-read mitigates some of it, but has drawbacks since it makes it more difficult to detect errors early. We will describe how we have rejected this tradeoff by applying schema metaprogramming, eliminating boilerplate but keeping the protection of static typing, thereby further improving agility to quickly modify data pipelines without fear.

Orchestrating the Future: Navigating Today's Data Workflow Challenges with Ai...
Navigating today's data landscape isn't just about managing workflows; it's about strategically propelling your business forward. Apache Airflow has stood out as the benchmark in this arena, driving data orchestration forward since its early days. As we dive into the complexities of our current data-rich environment, where the sheer volume of information and its timely, accurate processing are crucial for AI and ML applications, the role of Airflow has never been more critical.
In my journey as the Senior Engineering Director and a pivotal member of Apache Airflow's Project Management Committee (PMC), I've witnessed Airflow transform data handling, making agility and insight the norm in an ever-evolving digital space. At Astronomer, our collaboration with leading AI & ML teams worldwide has not only tested but also proven Airflow's mettle in delivering data reliably and efficiently—data that now powers not just insights but core business functions.
This session is a deep dive into the essence of Airflow's success. We'll trace its evolution from a budding project to the backbone of data orchestration it is today, constantly adapting to meet the next wave of data challenges, including those brought on by Generative AI. It's this forward-thinking adaptability that keeps Airflow at the forefront of innovation, ready for whatever comes next.
The ever-growing demands of AI and ML applications have ushered in an era where sophisticated data management isn't a luxury—it's a necessity. Airflow's innate flexibility and scalability are what makes it indispensable in managing the intricate workflows of today, especially those involving Large Language Models (LLMs).
This talk isn't just a rundown of Airflow's features; it's about harnessing these capabilities to turn your data workflows into a strategic asset. Together, we'll explore how Airflow remains at the cutting edge of data orchestration, ensuring your organization is not just keeping pace but setting the pace in a data-driven future.

Build applications with generative AI on Google Cloud
We will explore Vertex AI - Model Garden powered experiences, we are going to learn more about the integration of these generative AI APIs. We are going to see in action what the Gemini family of generative models are for developers to build and deploy AI-driven applications. Vertex AI includes a suite of foundation models, these are referred to as the PaLM and Gemini family of generative ai models, and they come in different versions. We are going to cover how to use via API to: - execute prompts in text and chat - cover multimodal use cases with image prompts. - finetune and distill to improve knowledge domains - run function calls with foundation models to optimize them for specific tasks. At the end of the session, developers will understand how to innovate with generative AI and develop apps using the generative ai industry trends.
ViewShift: Hassle-free Dynamic Policy Enforcement for Every Data Lake
Dynamic policy enforcement is becoming an increasingly important topic in today’s world where data privacy and compliance is a top priority for companies, individuals, and regulators alike. In these slides, we discuss how LinkedIn implements a powerful dynamic policy enforcement engine, called ViewShift, and integrates it within its data lake. We show the query engine architecture and how catalog implementations can automatically route table resolutions to compliance-enforcing SQL views. Such views have a set of very interesting properties: (1) They are auto-generated from declarative data annotations. (2) They respect user-level consent and preferences (3) They are context-aware, encoding a different set of transformations for different use cases (4) They are portable; while the SQL logic is only implemented in one SQL dialect, it is accessible in all engines.

Global Situational Awareness of A.I. and where its headed
You can see the future first in San Francisco.
Over the past year, the talk of the town has shifted from $10 billion compute clusters to $100 billion clusters to trillion-dollar clusters. Every six months another zero is added to the boardroom plans. Behind the scenes, there’s a fierce scramble to secure every power contract still available for the rest of the decade, every voltage transformer that can possibly be procured. American big business is gearing up to pour trillions of dollars into a long-unseen mobilization of American industrial might. By the end of the decade, American electricity production will have grown tens of percent; from the shale fields of Pennsylvania to the solar farms of Nevada, hundreds of millions of GPUs will hum.
The AGI race has begun. We are building machines that can think and reason. By 2025/26, these machines will outpace college graduates. By the end of the decade, they will be smarter than you or I; we will have superintelligence, in the true sense of the word. Along the way, national security forces not seen in half a century will be un-leashed, and before long, The Project will be on. If we’re lucky, we’ll be in an all-out race with the CCP; if we’re unlucky, an all-out war.
Everyone is now talking about AI, but few have the faintest glimmer of what is about to hit them. Nvidia analysts still think 2024 might be close to the peak. Mainstream pundits are stuck on the wilful blindness of “it’s just predicting the next word”. They see only hype and business-as-usual; at most they entertain another internet-scale technological change.
Before long, the world will wake up. But right now, there are perhaps a few hundred people, most of them in San Francisco and the AI labs, that have situational awareness. Through whatever peculiar forces of fate, I have found myself amongst them. A few years ago, these people were derided as crazy—but they trusted the trendlines, which allowed them to correctly predict the AI advances of the past few years. Whether these people are also right about the next few years remains to be seen. But these are very smart people—the smartest people I have ever met—and they are the ones building this technology. Perhaps they will be an odd footnote in history, or perhaps they will go down in history like Szilard and Oppenheimer and Teller. If they are seeing the future even close to correctly, we are in for a wild ride.
Let me tell you what we see.

A.为什么留学生需要操作留信认证?
留信认证全称全国留学生信息服务网认证,隶属于北京中科院。①留信认证门槛条件更低,费用更美丽,并且包过,完单周期短,效率高②留信认证虽然不能去国企,但是一般的公司都没有问题,因为国内很多公司连基本的留学生学历认证都不了解。这对于留学生来说,这就比自己光拿一个证书更有说服力,因为留学学历可以在留信网站上进行查询!
B.为什么我们提供的毕业证成绩单具有使用价值？
查询留服认证是国内鉴别留学生海外学历的唯一途径但认证只是个体行为不是所有留学生都操作所以没有办理认证的留学生的学历在国内也是查询不到的他们也仅仅只有一张文凭。所以这时候我们提供的和学校颁发的一模一样的毕业证成绩单就有了使用价值。只硕大的蛇皮袋手里拎着长铁钩正站在门口朝黑色的屋内张望不好坏人小偷山娃一怔却也灵机一动立马仰起头双手拢在嘴边朝楼上大喊：“爸爸爸——有人找——那人一听朝山娃尴尬地笑笑悻悻地走了山娃立马“嘭的一声将铁门锁死心却咚咚地乱跳当山娃跟父亲说起这事时父亲很吃惊抚摸着山娃的头说还好醒得及时要不家早被人掏空了到时连电视也没得看啰不过父亲还是夸山娃能临危不乱随机应变有胆有谋山娃笑笑说那都是书上学的看童话和小说时多

- 2. Presentation Outline • Transparency In Distributed DBMS • Different Aspects of Transparency in Distributed DBMS • Location Transparency • Fragmentation Transparency • Replication Transparency • References Department of Information Technology 2
- 3. Transparency In Distributed DBMS Transparency in DDBMS refers to the transparent distribution of information to the user from the system. Transparency aids in covering the information that the user is to apply. Distribution transparency is the property of distributed databases by the virtue of which the internal details of the distribution are hidden from the users. The DDBMS designer may choose to fragment tables, replicate the fragments and store them at different sites. However, since users are oblivious of these details, they find the distributed database easy to use like any centralized database. Transparency in for the DBMS stands separation of high level semantics of the system from the low-level implementation issue. Department of Information Technology
- 4. Different Aspects of Transparency in Distributed DBMS The three aspects of transparency in distribution are : Location transparency Fragmentation transparency Replication transparency Department of Information Technology
- 5. Location Transparency Clients should see a uniform file name space. Files or groups of files may be relocated without changing their pathnames. This property is important to support the movement of the resources and the availability of services. The location and access transparencies together are sometimes referred as Network transparency. If this type of transparency is provided by DDBMS, then it is necessary for the user to know how the data has been fragmented, but knowing the location of the data is not necessary. Department of Information Technology
- 6. Fragmentation Transparency Fragmentation transparency states that the fragments that are created to store the data in distributed manner should remain transparent and all the data management work required to control the fragments should be done by the system, not by the user. In this task, when a user puts a query, the global query is distributed in many sites to fetch data from fragments and this data is put together at the end to generate the result. The system ensures that the total procedure of query decomposition and re-composition should be transparent to the user. The user does not have to be aware of fragmented data in this type of transparency, which is why database accesses are based on the global schema. Department of Information Technology
- 7. Replication Transparency not by user. The user should not have any doubt about whether the fetched data is coming from replicated copy of the elation or from the actual copy of the relation. To achieve replication transparency the concurrency control protocol needs to be devised, which assures that the update of data taking place in one copy should also be updated in other copies. In this way, transparency regarding replicas of data can be maintained. Department of Information Technology
