Four Rules for Data Success describes why "Big Data" is such a hot concept right now. We take a look at four useful strategies for tackling big data problems, followed by examples of what a Big Data pipeline application looks like. Finally, we will take a few minutes to imagine what an ideal database system might look like.
Hosting and Sharing Terabytes of Raw Data describes how to solve the common challenge of hosting and sharing tons of files. This lesson starts with a discussion about why this task can be so challenge. Next, we will take a look at some common data formats and how to use infrastructure as a service technology to host and share files. We end this lesson by touching on common formats used in data serialization.
Building a NoSQL-Based Web App to Collect Crowd-Sourced Data introduces the technology necessary to handle huge volumes of constantly growing data. We start this lesson by learning about the history and use of relational databases. Next, we learn about why the relational model isn't always the best technology for handling large volumes of data. We then introduce a collection of technologies that break from the relational model, and demonstrate how to work with the key-value datastore, Redis. Finally, we take a look at future trends in database technology.
Strategies for Dealing with Data Silos covers why data becomes stranded in different locations, and what to do about it. This lesson starts with a discussion of the history and meaning of business intelligence. Next, we take a look at how Hadoop is affecting data warehousing. We then discuss ways in which Data Silos Can Be Good. We end this lesson by discussing technological convergence and the future of the Business Intelligence concept.
Using Hadoop, Hive, and Shark to Ask Questions about Large Data expands on the concepts of the previous lesson by providing an introduction to the data warehousing application Apache Hive. This lesson shows how to load and query data in Hive. It will also provide a short introduction to AMPLab's Shark, as well as take a look at new solutions for data warehousing in the cloud.
Building a Data Dashboard with Google BigQuery starts with an introduction to the concept of analytical databases. We take a look at Google's Dremel project, as well as the BigQuery API. We will run a BigQuery query and retrieve the result. We then learn how to visualize BigQuery result sets. Finally, we discuss the future of analytical query engines.
Visualization Strategies for Exploring Large Datasets introduces the concepts and history of data visualization. We begin this lesson with the goals of visualization, and a discussion of some of the pitfalls. We follow this with a collection of strategies for dealing with visualization of very large datasets. We then build interactive visualizations with R and ggplot2, and learn how to build 2D plots with Python and matplotlib. We will conclude this lesson by learning how to build interactive visualizations for the Web with D3.js.
Putting it together: MapReduce Data Pipelines describes how to bring together many of the concepts in our previous lessons by demonstrating how to pipe data from one place to another. We start by learning how to write a simple data pipeline script using UNIX command line tools. We then learn about how the Hadoop MapReduce framework works. Next, we write a Hadoop streaming MapReduce job in Python. We then get even more complex, by writing a multistep MapReduce job using the mrjob Python library. Finally, we will take a look at running mrjob scripts on Amazon's Elastic MapReduce.
Building Data Transformation Workflows with Pig and Cascading covers the challenges of building complex data workflows. We learn how to write a workflow script using Apache Pig. We then learn how to write data processing workflow applications with the Cascading library. Finally, we end the lesson with a discussion about when to use Pig versus Cascading.
Building a Data Classification System with Mahout, we take a look at some of the common use cases and limitations of machine learning technology. We then demonstrate some of the most common machine learning algorithms, such as bayesian classification, clustering, and recommendation engines. Next we introduce the Apache Mahout project, and demonstrate Bayesian classification. Finally, we take a look at some new innovations in open-source machine learning, including MLbase.
Using R with Large Datasets covers methods for understanding how memory is used by R. Next, we learn how to work with large matrices using R's bigmemory package. We then learn how to manipulate large data frames with ff, and how to run a linear regression over large datasets using biglm. Finally, we take a look at how to interface with Hadoop using R.
Building Analytics Workflows Using Python and Pandas starts with a discussion of when to choose one programming language for analytics over another. Next, we introduce the workhorse Python libraries of NumPy and SciPy, followed by the use of the Pandas library for analyzing time series data. We end this lesson by introducing the iPython notebook, which is becoming a ubiquitous tool in the data analytics world.
When to Build, When to Buy, When to Outsource teaches how to understand data problems in order to make the best decisions about purchasing. This lesson will cover guidelines for the build versus buy problem. Next, we take a look at the differences between public versus private data centers. We discuss the potential hidden costs of open-source software. Finally, we learn about the use and viability of analytics as a service technologies.
The Future: Trends in Data, we travel we first revisit some of the trends driving innovation in data analytics technology. We then discuss how the success of the open-source Apache Hadoop project has caused disruption in the data analytics space. Next, we take a look at analytics technologies in the cloud. The future isn't just about technology—so we take a look at the evolving definition of "data scientist." Finally we take a look at how converging technologies are setting the stage for future innovations in data analysis.
