Building the Data Lake with Azure Data Factory and Data Lake AnalyticsKhalid Salama
In essence, a data lake is commodity distributed file system that acts as a repository to hold raw data file extracts of all the enterprise source systems, so that it can serve the data management and analytics needs of the business. A data lake system provides means to ingest data, perform scalable big data processing, and serve information, in addition to manage, monitor and secure the it environment. In these slide, we discuss building data lakes using Azure Data Factory and Data Lake Analytics. We delve into the architecture if the data lake and explore its various components. We also describe the various data ingestion scenarios and considerations. We introduce the Azure Data Lake Store, then we discuss how to build Azure Data Factory pipeline to ingest the data lake. After that, we move into big data processing using Data Lake Analytics, and we delve into U-SQL.
This document covers guidelines around achieving multitenancy in a data lake environment. It mentions the different design and implementation guidelines necessary for on premise as well as cloud-based multitenant data lake, and highlights the reference architecture for both these deployment options.

The Data Mesh architectural design was first proposed in 2019 by Zhamak Dehghani, principal technology consultant at Thoughtworks, a technology company that is closely associated with the development of distributed agile methodology. A data mesh is a distributed, de-centralized data infrastructure in which multiple autonomous domains manage and expose their own data, called “data products,” to the rest of the organization.
Organizations leverage data mesh architecture when they experience shortcomings in highly centralized architectures, such as the lack domain-specific expertise in data teams, the inflexibility of centralized data repositories in meeting the specific needs of different departments within large organizations, and the slow nature of centralized data infrastructures in provisioning data and responding to changes.
In this session, Pablo Alvarez, Global Director of Product Management at Denodo, explains how data virtualization is your best bet for implementing an effective data mesh architecture.
You will learn:
- How data mesh architecture not only enables better performance and agility, but also self-service data access
- The requirements for “data products” in the data mesh world, and how data virtualization supports them
- How data virtualization enables domains in a data mesh to be truly autonomous
- Why a data lake is not automatically a data mesh
- How to implement a simple, functional data mesh architecture using data virtualization

This document discusses data warehousing, including its definition, importance, components, strategies, ETL processes, and considerations for success and pitfalls. A data warehouse is a collection of integrated, subject-oriented, non-volatile data used for analysis. It allows more effective decision making through consolidated historical data from multiple sources. Key components include summarized and current detailed data, as well as transformation programs. Common strategies are enterprise-wide and data mart approaches. ETL processes extract, transform and load the data. Clean data and proper implementation, training and maintenance are important for success.

Azure Data Factory is a data integration service that allows for data movement and transformation between both on-premises and cloud data stores. It uses datasets to represent data structures, activities to define actions on data with pipelines grouping related activities, and linked services to connect to external resources. Key concepts include datasets representing input/output data, activities performing actions like copy, and pipelines logically grouping activities.
The document provides an overview of a Power BI training course. The course objectives include learning about connecting to data sources, transforming data, building data model relationships, using DAX functions to transform data, and creating visualizations. It discusses topics like importing data from CSV and Excel files into Power BI, using Power Query to transform data, establishing relationships between tables in the data model, using measures and columns with DAX, and building basic and dynamic visualizations. It also provides resources for sample data files and additional learning materials for the course.
Data Warehouse or Data Lake, Which Do I Choose?DATAVERSITY
Today’s data-driven companies have a choice to make – where do we store our data? As the move to the cloud continues to be a driving factor, the choice becomes either the data warehouse (Snowflake et al) or the data lake (AWS S3 et al). There are pro’s and con’s for each approach. While the data warehouse will give you strong data management with analytics, they don’t do well with semi-structured and unstructured data with tightly coupled storage and compute, not to mention expensive vendor lock-in. On the other hand, data lakes allow you to store all kinds of data and are extremely affordable, but they’re only meant for storage and by themselves provide no direct value to an organization.
Enter the Open Data Lakehouse, the next evolution of the data stack that gives you the openness and flexibility of the data lake with the key aspects of the data warehouse like management and transaction support.
In this webinar, you’ll hear from Ali LeClerc who will discuss the data landscape and why many companies are moving to an open data lakehouse. Ali will share more perspective on how you should think about what fits best based on your use case and workloads, and how some real world customers are using Presto, a SQL query engine, to bring analytics to the data lakehouse.
Data Mining is newly technology and it's very useful for Data analytics for business analysis purpose and decision making data. This PPT described Data Mining in very easy way.
Data mining is the process of automatically discovering useful information from large data sets. It draws from machine learning, statistics, and database systems to analyze data and identify patterns. Common data mining tasks include classification, clustering, association rule mining, and sequential pattern mining. These tasks are used for applications like credit risk assessment, fraud detection, customer segmentation, and market basket analysis. Data mining aims to extract unknown and potentially useful patterns from large data sets.
Essential Reference and Master Data ManagementDATAVERSITY
Data tends to pile up and can be rendered unusable or obsolete without careful maintenance processes. Reference and Master Data Management (MDM) has been a popular Data Management approach to effectively gain mastery over not just the data but the supporting architecture for processing it. This webinar presents MDM as a strategic approach to improving and formalizing practices around those data items that provide context for many organizational transactions: its master data. Too often, MDM has been implemented technology-first and achieved the same very poor track record (one-third succeeding on-time, within budget, and achieving planned functionality). MDM success depends on a coordinated approach typically involving Data Governance and Data Quality activities.
Learning objectives:
- Understand foundational reference and MDM concepts based on the Data Management Body of Knowledge (DMBOK)
- Understand why these are an important component of your Data Architecture
- Gain awareness of Reference and MDM Frameworks and building blocks
- Know what MDM guiding principles consist of and best practices
- Know how to utilize reference and MDM in support of business strategy
This document discusses developing metrics to assess how well digital resources adhere to the FAIR principles of findability, accessibility, interoperability, and reusability. It provides examples of potential metrics that could be used to measure compliance with each of the FAIR principles. It also discusses challenges around developing standardized and automated metrics given differences in resource types and communities. The goal is to define FAIRness indices made up of agreed upon metrics to help improve the findability, accessibility, interoperability and reusability of digital resources.
This document provides an overview of data warehousing and online analytical processing (OLAP). It defines a data warehouse as a single, consistent store of subject-oriented data obtained from various sources to support end-user business analysis and decision-making.

This will include:
The Lab and the factory
The base environment for batch analytics
Critical governance components
Additional components necessary for real-time analytics and ingesting streaming data
The document discusses temporal databases, which store information about how data changes over time. It covers several key points:
- Temporal databases allow storage of past and future states of data, unlike traditional databases which only store the current state.
- Time can be represented in terms of valid time (when facts were true in the real world) and transaction time (when facts were current in the database). Temporal databases may track one or both dimensions.
- SQL supports temporal data types like DATE, TIME, TIMESTAMP, INTERVAL and PERIOD for representing time values and durations.
- Temporal information can describe point events or durations. Relational databases incorporate time by adding timestamp attributes, while object databases
This document provides an overview of key concepts related to data warehousing including what a data warehouse is, common data warehouse architectures, types of data warehouses, and dimensional modeling techniques. It defines key terms like facts, dimensions, star schemas, and snowflake schemas and provides examples of each. It also discusses business intelligence tools that can analyze and extract insights from data warehouses.
Microsoft Power BI is a cloud-based business analytics service. This document provides an overview of Power BI and its key capabilities. It discusses connecting to various data sources, creating reports and dashboards, exploring data using natural language queries, and sharing insights across an organization. The document also describes the Power BI online service experience and how to work with reports, dashboards, and collaborate with others.
Big data analytics tools from vendors like IBM, Tableau, and SAS can help organizations process and analyze big data. For smaller organizations, Excel is often used, while larger organizations employ data mining, predictive analytics, and dashboards. Business intelligence applications include OLAP, data mining, and decision support systems. Big data comes from many sources like web logs, sensors, social networks, and scientific research. It is defined by the volume, variety, velocity, veracity, variability, and value of the data. Hadoop and MapReduce are common technologies for storing and analyzing big data across clusters of machines. Stream analytics is useful for real-time analysis of data like sensor data.

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.
The document discusses databases versus data warehousing. It notes that databases are for operational purposes like storage and retrieval for applications, while data warehouses are used for informational purposes like business reporting and analysis. A data warehouse contains integrated, subject-oriented data from multiple sources that is used to support management decisions.
Data resource management involves applying information systems technology to manage data resources. It includes activities like creating, storing, organizing, and retrieving data using database management systems. There are different types of databases like operational, distributed, data warehouses, data marts, and end user databases. Data warehouses store historical data from various operational databases to help identify trends. Data mining techniques are used to better understand data through analysis, sorting, extracting patterns and relationships to gain insights. Common applications of data mining include banking, customer relationship management, targeted marketing, fraud detection, and scientific data analysis.

8. The BI Sandbox, defined
Responsibilities • To facilitate short term ad-hoc exploratory analysis.
• To remove roadblocks to client self-service (minimizing the need for I/S
assistance) with short term ad-hoc exploratory analysis.
• To avoid the creation of unmanaged spreadsheet based data on user
desktops or shared network drives.
• To better enable short term ad-hoc exploratory analysis to be converted to
long term operational analysis as needed (through traceability)
Collaborators Semantic Layer, Operational Data Layer (ODL), Analytic Data Layer (ADL)
Rationale Typically reporting and analysis is ongoing, consistent, and can be enabled by
production structures such as ODSs and data marts.
Occasionally, business requirements indicate a need for temporary or ad-hoc
exploratory data analysis that cannot be supported by existing data structures.
These business requirements often results in unmanaged disparate spreadsheet data
on individual user desktops or shared network drives.
Sandboxes are meant to mitigate the risk that these ad hoc data sets are created
through inconsistent techniques and the subsequent risk that analytical results
discovered by using them are hard to trace and convert to a more permanent
process; and doing so typically requires a complex project to convert the untraceable
data set, integration, and analytical rules into repeatable rules.
9. The BI Sandbox, defined
Issues and
Notes
• Sandbox data sets will be short-lived.
• The sandbox will support Ad hoc analysis.
• Sandbox data sets will be intended for a specific purpose.
• Reporting generated from the sandbox will not be considered “official”.
• Sandbox data sets should be transitional.
• Sandboxes, if they cannot be decommissioned, should be transitioned into
production structures (e.g., ODSs or data marts).
• Sandbox data set structure/format will be dependent on access tools.
• Sandbox data set composition and quality will be dependent on the source.
• Sandbox check-out (data validation) strategy will be the responsibility of the
end user.
• Sandbox data sets should require minimal I/S intervention.
• Sandbox data can come from external or user supplied sources.
• Data acquisition from operational systems is restricted.
• Sandbox data will not be automatically refreshed on a regular basis.
• Naming standards do not apply to sandbox structures.
10. The BI Sandbox, the real why
• Shed light on data integration work clients do
whether I/S wishes to acknowledge it or not
• Increase partnership between I/S and business
– I/S has an appropriate solution to offer for more real
problems
• Most innovation doesn’t happen in well-defined
structures
11. The BI Sandbox, the how
Provide a place to play
• Typically SAS storage
Bring your own toys
• Manual loads of data from various sources including
• Data marts
• ODSs
• Operational systems
• User-supplied data sets
Create & Learn
• Use analysis tools (Business Objects, SAS, Excel) to
explore the data and discover
Transfer what you learn elsewhere
• Covert discoveries into operational changes to build
value
12. The BI Sandbox, the limitations
• Joins between disparate sources on natural keys
alone
– Operational system keys
– Functional keys
• No cleansing, no column renaming, minimal
metadata, no data modeling
• No automated refresh process
13. The BI Sandbox, the examples
• Prototyping new enterprise measure
• Experimenting with integration of disparate data
sources
• Predictive model creation, testing & validation
(in parallel with production development)
