Everyday huge amount of data is created. This data comes from everywhere : sensors used to gather climate information, post to social media sites, digital pictures and videos, purchase transaction records and Cell phone GPS signals to name a few. This data is Big Data.
Big data is a blanket term for any collection of data set so large and complex that it becomes difficult to process using on hand data management tools or traditional data processing applications. The challenges include capture, storage, search, sharing, transfer, analysis and visualization. Anyone who has knowledge on Java, basic UNIX and basic SQL can opt for Big Data training course.

Building the Architecture for Analytic CompetitionWilliam McKnight
Lost amid the conversation on big data and the accelerating advancement of just about every aspect of enterprise software that manages information are the things that hold it all together. Yet this is critical: information-management components must come together in a meaningful fashion or there will be unneeded redundancy and waste and opportunities missed. Considering that optimizing the information asset goes directly to the organization’s bottom line, it behooves us to play an exceptional game— not a haphazard one—with our technology building blocks.

The Building Blocks of QuestDB, a Time Series Databasejavier ramirez
Talk Delivered at Valencia Codes Meetup 2024-06.
Traditionally, databases have treated timestamps just as another data type. However, when performing real-time analytics, timestamps should be first class citizens and we need rich time semantics to get the most out of our data. We also need to deal with ever growing datasets while keeping performant, which is as fun as it sounds.
It is no wonder time-series databases are now more popular than ever before. Join me in this session to learn about the internal architecture and building blocks of QuestDB, an open source time-series database designed for speed. We will also review a history of some of the changes we have gone over the past two years to deal with late and unordered data, non-blocking writes, read-replicas, or faster batch ingestion.
Levelwise PageRank with Loop-Based Dead End Handling Strategy : SHORT REPORT ...Subhajit Sahu
Abstract — Levelwise PageRank is an alternative method of PageRank computation which decomposes the input graph into a directed acyclic block-graph of strongly connected components, and processes them in topological order, one level at a time. This enables calculation for ranks in a distributed fashion without per-iteration communication, unlike the standard method where all vertices are processed in each iteration. It however comes with a precondition of the absence of dead ends in the input graph. Here, the native non-distributed performance of Levelwise PageRank was compared against Monolithic PageRank on a CPU as well as a GPU. To ensure a fair comparison, Monolithic PageRank was also performed on a graph where vertices were split by components. Results indicate that Levelwise PageRank is about as fast as Monolithic PageRank on the CPU, but quite a bit slower on the GPU. Slowdown on the GPU is likely caused by a large submission of small workloads, and expected to be non-issue when the computation is performed on massive graphs.
Global Situational Awareness of A.I. and where its headedvikram sood
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.

Adjusting OpenMP PageRank : SHORT REPORT / NOTESSubhajit Sahu
For massive graphs that fit in RAM, but not in GPU memory, it is possible to take
advantage of a shared memory system with multiple CPUs, each with multiple cores, to
accelerate pagerank computation. If the NUMA architecture of the system is properly taken
into account with good vertex partitioning, the speedup can be significant. To take steps in
this direction, experiments are conducted to implement pagerank in OpenMP using two
different approaches, uniform and hybrid. The uniform approach runs all primitives required
for pagerank in OpenMP mode (with multiple threads). On the other hand, the hybrid
approach runs certain primitives in sequential mode (i.e., sumAt, multiply).
ViewShift: Hassle-free Dynamic Policy Enforcement for Every Data LakeWalaa Eldin Moustafa
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.

14. Data Architecture
Architecture refers to the art and science of building
things (especially habitable structures) and to the results
of the process of building – the buildings themselves. In
a more general sense, architecture refers to an organized
arrangement of component elements intended to
optimize the function, performance, feasibility, cost, and
aesthetics of an overall structure or system.
Data Architecture is fundamental to data management.
Because most organizations have more data than
individual people can comprehend, it is necessary to
represent organizational data at different levels of
abstraction so that it can be understood and management
can make decisions about it.
15. Data ArchitectureDefinition
Identifying the data needs of the enterprise
(regardless of structure), and designing
and maintaining the master blueprints to
meet those needs. Using master blueprints
to guide data integration, control data
assets, and align data investments with
business strategy.
20. Data extraction
Data extracted from data sources may be stored
temporarily into a temporary data store or directly
transferred, and loaded into a Raw data store. Streaming
data may also be extracted, and stored temporarily.
24. Data processing
Data from the Raw data store may be cleaned or
combined, and saved into a new Preparation data
store, which temporarily holds processed data.
Cleaning and combining refer to quality
improvement of the raw unprocessed data. Raw
and prepared data may be replicated between data
stores. Also, new information may be extracted
from the Raw data store for Deep Analytics.
Information extraction refers to storing of raw
data in a structured format. The Enterprise data
store is used for holding of cleaned and processed
data. The Sand-box store is used for containing
data for experimental purposes of data analysis.
26. Data analysis
Deep Analytics refers to execution of batch-
processing jobs for in situ data. Results of the
analysis may be stored back into the original data
stores, into a separate Analysis results store or
into a Publish & subscribe store. Publish &
subscribe store enables storage and retrieval of
analysis results indirectly between subscribers
and publishers in the system. Stream processing
refers to processing of extracted streaming data,
which may be saved temporarily before analysis.
Stream analysis refers to analysis of streaming
data, to be saved into Stream analysis results.
28. Data loading and transformation
Results of the data analysis may also be
transformed into a Serving data store, which
serve interfacing and visualization applications.
A typical application for transformation and
Serving data store is servicing of Online
Analytical Processing (OLAP) queries.
30. Interfacing and visualization
Analyzed data may be visualized in several
ways. Dashboarding application refers to a
simple UI, where typically key information is
visualized without user control. Visualization
application provides detailed visualization and
control functions, and is realized with a Business
Intelligence tool in the enterprise domain. End
user application has a limited set of control
functions, and could be realized as a mobile
application for end users.
32. Joband modelspecification
Batch-processing jobs may be
specified in the user interface.
The jobs may be saved and
scheduled with job scheduling
tools. Models/algorithms may
also be specified in the user
interface (Model specification).
Machine learning tools may be
utilized for training of the
models based on new extracted
data.
44. Data Governance
Data Governance (DG) is defined as the exercise of
authority and control (planning, monitoring, and
enforcement) over the management of data assets. All
organizations make decisions about data, regardless of
whether they have a formal Data Governance function.
Those that establish a formal Data Governance program
exercise authority and control with greater intentionality
(Seiner, 2014). Such organizations are better able to
increase the value they get from their data assets. The
Data Governance function guides all other data
management functions. The purpose of Data
Governance is to ensure that data is managed properly,
according to policies and best practices
45. Data Governance Definition
The exercise of authority, control, and
shared decision-making (planning,
monitoring, and enforcement) over the
management of data assets.
52. Maturity Model
-Stanford’s Maturity Model (https://lnkd.in/gs-Qsp4)
-IBM’s Maturity Model (https://lnkd.in/gPArsvH)
-Kalido Maturity Model(https://lnkd.in/gg3J7aJ)

61. Modeling& Design
Data modeling is the process of discovering, analyzing,
and scoping data requirements, and then representing
and communicating these data requirements in a precise
form called the data model. Data modeling is a critical
component of data management. The modeling process
requires that organizations discover and document how
their data fits together. The modeling process itself
designs how data fits together (Simsion, 2013). Data
models depict and enable an organization to understand
its data assets.
62. Data ModelingDefinition
Data modeling is the process of
discovering, analyzing, and scoping data
requirements, and then representing and
communicating these data requirements in
a precise form called the data model. This
process is iterative and may include a
conceptual, logical, and physical model.
64. different schemes
There are a number of different schemes
used to represent data. The six most
commonly used schemes are: Relational,
Dimensional, Object-Oriented, Fact-
Based, Time-Based, and NoSQL. Models
of these schemes exist at three levels of
detail: conceptual, logical, and physical.
Each model contains a set of components.
Examples of components are entities,
relationships, facts, keys, and attributes.
Once a model is built, it needs to be
reviewed and once approved, maintained.
65. Entity
Outside of data modeling, the definition of
entity is a thing that exists separate from
other things. Within data modeling, an
entity is a thing about which an
organization collects information.
68. CDM,LDM,PDM
Conceptual Data Model
The conceptual Data Model (CDM) helps you analyze the conceptual structure of an
information system and then identifies the major entities that need to be described, the
attributes in those entities, and the relationships between those entities. Conceptual data
models are more abstract than logical or physical data models.
Logical Data Model
The logical Data Model (LDM) helps you analyze the structure of the information system,
independent of any specific physical database implementation. LDM already involves entity
identifiers, which are not as abstract as CDM, but do not allow you to design elements of
views, indexes, and other more specific physical data models.
Physical Data Model
The physical Data Model (PDM) helps you analyze tables, views, and other database objects,
including the multidimensional objects required by the Data warehouse. PDM is more specific
than CDM and LDM. You can model, reverse engineer, and Kazuo into all the most popular
