Data Lakes are early in the Gartner hype cycle, but companies are getting value from their cloud-based data lake deployments. Break through the confusion between data lakes and data warehouses and seek out the most appropriate use cases for your big data lakes.
Big data architectures and the data lakeJames Serra
With so many new technologies it can get confusing on the best approach to building a big data architecture. The data lake is a great new concept, usually built in Hadoop, but what exactly is it and how does it fit in? In this presentation I'll discuss the four most common patterns in big data production implementations, the top-down vs bottoms-up approach to analytics, and how you can use a data lake and a RDBMS data warehouse together. We will go into detail on the characteristics of a data lake and its benefits, and how you still need to perform the same data governance tasks in a data lake as you do in a data warehouse. Come to this presentation to make sure your data lake does not turn into a data swamp!
Modernizing to a Cloud Data ArchitectureDatabricks
Organizations with on-premises Hadoop infrastructure are bogged down by system complexity, unscalable infrastructure, and the increasing burden on DevOps to manage legacy architectures. Costs and resource utilization continue to go up while innovation has flatlined. In this session, you will learn why, now more than ever, enterprises are looking for cloud alternatives to Hadoop and are migrating off of the architecture in large numbers. You will also learn how elastic compute models’ benefits help one customer scale their analytics and AI workloads and best practices from their experience on a successful migration of their data and workloads to the cloud.
Data Lakehouse, Data Mesh, and Data Fabric (r1)James Serra
So many buzzwords of late: Data Lakehouse, Data Mesh, and Data Fabric. What do all these terms mean and how do they compare to a data warehouse? In this session I’ll cover all of them in detail and compare the pros and cons of each. I’ll include use cases so you can see what approach will work best for your big data needs.
This is a presentation I gave in 2006 for Bill Inmon. The presentation covers Data Vault and how it integrates with Bill Inmon's DW2.0 vision. This is focused on the business intelligence side of the house.

Enterprise Architecture vs. Data ArchitectureDATAVERSITY
Enterprise Architecture (EA) provides a visual blueprint of the organization, and shows key interrelationships between data, process, applications, and more. By abstracting these assets in a graphical view, it’s possible to see key interrelationships, particularly as they relate to data and its business impact across the organization. Join us for a discussion on how Data Architecture is a key component of an overall Enterprise Architecture for enhanced business value and success.
Making Data Timelier and More Reliable with Lakehouse TechnologyMatei Zaharia
Enterprise data architectures usually contain many systems—data lakes, message queues, and data warehouses—that data must pass through before it can be analyzed. Each transfer step between systems adds a delay and a potential source of errors. What if we could remove all these steps? In recent years, cloud storage and new open source systems have enabled a radically new architecture: the lakehouse, an ACID transactional layer over cloud storage that can provide streaming, management features, indexing, and high-performance access similar to a data warehouse. Thousands of organizations including the largest Internet companies are now using lakehouses to replace separate data lake, warehouse and streaming systems and deliver high-quality data faster internally. I’ll discuss the key trends and recent advances in this area based on Delta Lake, the most widely used open source lakehouse platform, which was developed at Databricks.

In the presentation I’ll discuss why you still need a relational data warehouse and how to use a data lake and a RDBMS data warehouse to get the best of both worlds. I will go into detail on the characteristics of a data lake and its benefits and why you still need data governance tasks in a data lake. I’ll also discuss using Hadoop as the data lake, data virtualization, and the need for OLAP in a big data solution. And I’ll put it all together by showing common big data architectures.
How a Semantic Layer Makes Data Mesh Work at ScaleDATAVERSITY
Data Mesh is a trending approach to building a decentralized data architecture by leveraging a domain-oriented, self-service design. However, the pure definition of Data Mesh lacks a center of excellence or central data team and doesn’t address the need for a common approach for sharing data products across teams. The semantic layer is emerging as a key component to supporting a Hub and Spoke style of organizing data teams by introducing data model sharing, collaboration, and distributed ownership controls.
This session will explain how data teams can define common models and definitions with a semantic layer to decentralize analytics product creation using a Hub and Spoke architecture.
Attend this session to learn about:
- The role of a Data Mesh in the modern cloud architecture.
- How a semantic layer can serve as the binding agent to support decentralization.
- How to drive self service with consistency and control.

Can data models replace traditional metadata solutions? Or should they integrate with larger metadata management tools & initiatives?
Join this webinar to discuss opportunities and challenges around:
How data modeling fits within a larger metadata management landscape
When can data modeling provide “just enough” metadata management
Key data modeling artifacts for metadata
Organization, Roles & Implementation Considerations
A Reference Process Model for Master Data ManagementBoris Otto
The management of master data (MDM) plays an important role for companies in responding to a number of business drivers such as regulatory compliance and efficient reporting. With the understanding of MDM’s impact on the business drivers companies are today in the process of organizing MDM on corporate level. While managing master data is an organizational task that cannot be encountered by simply implementing a software system, business processes are necessary to meet the challenges efficiently. This paper describes the design process of a reference process model for MDM. The model design process spanned several iterations comprising multiple design and evaluation cycles, including the model’s application in three participative case studies. Practitioners may use the reference model as an instrument for the analysis and design of MDM processes. From a scientific perspective, the reference model is a design artifact that represents an abstraction of processes in the field of MDM.

Gain New Insights by Analyzing Machine Logs using Machine Data Analytics and BigInsights.
Half of Fortune 500 companies experience more than 80 hours of system down time annually. Spread evenly over a year, that amounts to approximately 13 minutes every day. As a consumer, the thought of online bank operations being inaccessible so frequently is disturbing. As a business owner, when systems go down, all processes come to a stop. Work in progress is destroyed and failure to meet SLA’s and contractual obligations can result in expensive fees, adverse publicity, and loss of current and potential future customers. Ultimately the inability to provide a reliable and stable system results in loss of $$$’s. While the failure of these systems is inevitable, the ability to timely predict failures and intercept them before they occur is now a requirement.
A possible solution to the problem can be found is in the huge volumes of diagnostic big data generated at hardware, firmware, middleware, application, storage and management layers indicating failures or errors. Machine analysis and understanding of this data is becoming an important part of debugging, performance analysis, root cause analysis and business analysis. In addition to preventing outages, machine data analysis can also provide insights for fraud detection, customer retention and other important use cases.

Techniques to optimize the pagerank algorithm usually fall in two categories. One is to try reducing the work per iteration, and the other is to try reducing the number of iterations. These goals are often at odds with one another. Skipping computation on vertices which have already converged has the potential to save iteration time. Skipping in-identical vertices, with the same in-links, helps reduce duplicate computations and thus could help reduce iteration time. Road networks often have chains which can be short-circuited before pagerank computation to improve performance. Final ranks of chain nodes can be easily calculated. This could reduce both the iteration time, and the number of iterations. If a graph has no dangling nodes, pagerank of each strongly connected component can be computed in topological order. This could help reduce the iteration time, no. of iterations, and also enable multi-iteration concurrency in pagerank computation. The combination of all of the above methods is the STICD algorithm. [sticd] For dynamic graphs, unchanged components whose ranks are unaffected can be skipped altogether.
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.

What is a “data lake”
data lake (plural data lakes)
A massive, easily accessible data repository
built on (relatively) inexpensive computer
hardware for storing "big data". Unlike data marts,
which are optimized for data analysis by storing only some
attributes and dropping data below the level aggregation, a
data lake is designed to retain all attributes,
especially so when you do not yet know what the
scope of data or its use will be.

What reporting does for established operations … discovery analytics does for new business development.
The trend within industry is to move away from the single-‐platform monolithic data warehouses towards a physically distributed environment
for information delivery. Many businesses are extending their data warehouse environments to include new standalone data platforms that
are conducive to discovery analytics. A holistic view is maintained via a common, single replicated dataset and an enterprise information
management program, governing delivery and access to key information (data lake).

Principles: Easier access information to discover new
facts about the business.
◦ Described as a ‘sandpit’ environment, providing the ability to explore and discover new
facts about the business, it’s members and customers, partners and competitive
pressures.
◦ Also used for testing a hypothesis or running scenarios across the data
◦ Getting answers to ‘one-‐off’ questions which are not addressed through the normal
published, scheduled operational reporting channels
◦ Data is replicated from all operational systems into a single landing area, ensuring
traceability and reconciliation to all consuming applications, such as the data warehouse,
analytical application, and other business applications.
◦ Clearly defined critical business entities/records are synchronised (or Mastered) across
all applications eliminating duplication and confusion. Data quality attributes are defined
and managed for each critical business entity.
◦ A fully integrated Member/Customer view is established across both analytical and
transactional applications.
◦ Using the replicated data to build more dynamic analytical data structures for scheduled
production reporting and ah-‐hoc analysis
◦ Provide users with the tools to access and analyse data, freely explore current and new
datasets, and visualise patterns and discoveries to gain deep insights.
Providing business users with direct
access to data to meet immediate
information needs where the
accuracy of the data is not the
primary objective.
Having a single source of truth
across all business applications at
detailed level from which all
information requests are satisfied.
Improved environment for more
cost effective and faster business
intelligence delivery.
Provide business users with the ability to access production information directly, collect it as needed, and
prepare the data for analysis. Exploring the data to uncover previously unknown facts about the business, and
sharing those facts visually with others. Enrich production data with external “context” to extend insights.
Key Principles Description

Benefits of Discovery Analytics versus traditional data
warehousing
Classic Data Warehouse Issues Discovery Analytics Benefit
Lengthy IT Backlog and lack of resources to extend the
EDW to support new business requirements.
Data can be explored and analysed outside of the EDW
environment before it is put into production use.
High costs of supporting increasing data volumes and
new types of data.
Data can be filtered and transformed before it is loaded
into the EDW
Lack of flexibility in the EDW data model to support
constantly changing business requirements.
Data discovery support dynamic schema on read
approach which reduces the need for detailed up-‐front
modelling.
Need to have data quality and governance processes in
place before user can access the EDW data.
The investigative nature of data discovery has lower data
quality and governance requirements
Growing use of personal data marts to overcome IT
barriers and the performance overheads of ad hoc
processing
The flexibility and performance of data discovery
encourages shared use of data and analytics.
Recent proof of concept for Discovery Analytics in the cloud (AWS), has provided some
considerable cost & time savings in infrastructure and hosting, viz.:
$55 per day to host a 960GB data warehouse
$32 per day to host a Data Integration server AND a BI server.
2.5 weeks to setup POC environment and start analysis and visualising results.
