This document discusses the challenges of data modeling in the era of big data and the need for data modeling tools to evolve to represent both traditional relational databases and non-relational data stores used in big data systems. It provides an overview of how the data landscape has changed with the rise of big data and NoSQL databases. It also describes a proof of concept project where CA used its data modeling tool to reverse engineer and represent both relational and non-relational data from its products stored in a Hadoop cluster. The document argues that a unified view of all enterprise data spread across different data systems is needed and possible.
The document discusses how SQL and NoSQL databases can work together for big data. It provides an overview of relational databases based on Codd's rules and how NoSQL databases are used for less structured data like documents and graphs. Examples of using MongoDB and Hadoop are provided. The document also discusses using MySQL with memcached to get the benefits of both SQL and NoSQL for accessing data.
MongoDB is a document-oriented NoSQL database that uses JSON-like documents with optional schemas. It provides high performance, high availability, and easy scalability. MongoDB is also called "humongous" because it is designed to store and handle large volumes of data. Some key advantages of MongoDB include its ability to handle large, unstructured data sets and provide agile development with quick code iterations.

This document provides an introduction to NoSQL databases. It discusses that NoSQL databases are non-relational, do not require a fixed table schema, and do not require SQL for data manipulation. It also covers characteristics of NoSQL such as not using SQL for queries, partitioning data across machines so JOINs cannot be used, and following the CAP theorem. Common classifications of NoSQL databases are also summarized such as key-value stores, document stores, and graph databases. Popular NoSQL products including Dynamo, BigTable, MongoDB, and Cassandra are also briefly mentioned.
Integrating Hadoop Into the Enterprise – Hadoop Summit 2012Jonathan Seidman
A look at common patterns being applied to leverage Hadoop with traditional data management systems and the emerging landscape of tools which provide access and analysis of Hadoop data with existing systems such as data warehouses, relational databases, and business intelligence tools.
The rising interest in NoSQL technology over the last few years resulted in an increasing number of evaluations and comparisons among competing NoSQL technologies From survey we create a concise and up-to-date comparison of NoSQL engines, identifying their most beneficial use from the software engineer point of view.
The document discusses and compares MapReduce and relational database management systems (RDBMS) for large-scale data processing. It describes several hybrid approaches that attempt to combine the scalability of MapReduce with the query optimization and efficiency of parallel RDBMS. HadoopDB is highlighted as a system that uses Hadoop for communication and data distribution across nodes running PostgreSQL for query execution. Performance evaluations show hybrid systems can outperform pure MapReduce but may still lag specialized parallel databases.

HugeTable:Application-Oriented Structure Data Storage Systemqlw5
HugeTable is an application-oriented structured data storage system designed to address the needs of handling huge data volumes for multiple applications areas at China Mobile. It is built on Hadoop and HBase and aims to provide SQL support, fast index queries, support for multiple applications, and CRUD operations. HugeTable has been through several versions to add features like global indexing, secondary indexing, schema support, and application integration. It uses HBase as an index store and provides various APIs, administration tools, and solutions for telecommunications applications at China Mobile requiring analytics of large datasets.
Comparing Hive with HBase is like comparing Google with Facebook - although they compete over the same turf (our private information), they don’t provide the same functionality. But things can get confusing for the Big Data beginner when trying to understand what Hive and HBase do and when to use each one of them. We're going to clear it up.
Domain Driven Design is a software development process that focuses on finding a common language for the involved parties. This language and the resulting models are taken from the domain rather than the technical details of the implementation. The goal is to improve the communication between customers, developers and all other involved groups. Even if Eric Evan's book about this topic was written almost ten years ago, this topic remains important because a lot of projects fail for communication reasons.
Relational databases have their own language and influence the design of software into a direction further away from the Domain: Entities have to be created for the sole purpose of adhering to best practices of relational database. Two kinds of NoSQL databases are changing that: Document stores and graph databases. In a document store you can model a "contains" relation in a more natural way and thereby express if this entity can exist outside of its surrounding entity. A graph database allows you to model relationships between entities in a straight forward way that can be expressed in the language of the domain.
In this talk I want to look at the way a multi model database that combines a document store and a graph database can help you to model your problems in a way that is understandable for all parties involved, and explain the benefits of this approach for the software development process.
This presentation Simplify the concepts of Big data and NoSQL databases & Hadoop components.

A Survey of Petabyte Scale Databases and Storage Systems Deployed at FacebookBigDataCloud
At Facebook, we use various types of databases and storage system to satisfy the needs of different applications. The solutions built around these data store systems have a common set of requirements: they have to be highly scalable, maintenance costs should be low and they have to perform efficiently. We use a sharded mySQL+memcache solution to support real-time access of tens of petabytes of data and we use TAO to provide consistency of this web-scale database across geographical distances. We use Haystack datastore for storing the 3 billion new photos we host every week. We use Apache Hadoop to mine intelligence from 100 petabytes of clicklogs and combine it with the power of Apache HBase to store all Facebook Messages.
This talk describes the reasons why each of these databases are appropriate for their workloads and the design decisions and tradeoffs that were made while implementing these solutions. We touch upon the consistency, availability and partitioning tolerance of each of these solutions. We touch upon the reasons why some of these systems need ACID semantics and other systems do not. We briefly touch upon some futures of how we plan to do big-data deployments across geographical locations and our requirements for a new breed of pure-memory and pure-SSD based transactional database.

Essentials of Automations: Exploring Attributes & Automation ParametersSafe Software
Building automations in FME Flow can save time, money, and help businesses scale by eliminating data silos and providing data to stakeholders in real-time. One essential component to orchestrating complex automations is the use of attributes & automation parameters (both formerly known as “keys”). In fact, it’s unlikely you’ll ever build an Automation without using these components, but what exactly are they?
Attributes & automation parameters enable the automation author to pass data values from one automation component to the next. During this webinar, our FME Flow Specialists will cover leveraging the three types of these output attributes & parameters in FME Flow: Event, Custom, and Automation. As a bonus, they’ll also be making use of the Split-Merge Block functionality.
You’ll leave this webinar with a better understanding of how to maximize the potential of automations by making use of attributes & automation parameters, with the ultimate goal of setting your enterprise integration workflows up on autopilot.

Session Agenda
— Where are we & how do we get here?
— Overview of the Big Data world
— Challenges to enterprises and data architect
— Extending data modeling to include Big Data
—Q&A
3
4. Data Modeling Past 30 Years
— Entity-Relationship (ER) modeling has served us well
since mid-70’s
— Data architects / modelers have used ER tools to
ensure data consistencies and integrities for very
large enterprises
— Ability to integrate new databases from mergers and
acquisitions;
— A map of where all your data;
— Ability to handle large & complex data model;
— Then, the Internet & social networks
4
5. Internet & Social Networks
— Early Internet used the classical LAMP stack – Linux,
Apache Web Server, MySQL Database, and
Perl/PHP/Python
— Basic web servers & DB’s served us well for basic
web portal
— Internet growth + social networks changed the scale
of database / data store
— Traditional relational databases have difficulties
handling the scale & required (sub second) response
time for web
— Emergences of NoSQL data store
5
6. Arrival of Big Data
— Wealth of valuable data to collect:
− Users entered information
− History / logs of users interaction
— Not always fit nicely into structured data stores
(relational or NoSQL)
— Need to harvest / analyze the data to compete
— Challenges of
capturing, storing, searching, anlayzing, and
visualizing very large and complex data sets
— Large, distributed, analytical platforms (Hadoop)
emerged

8. Problem of Non-Relational Data Stores
— NoSQL and unstructured data store performance has
a price:
− Denormalized data
− Data consistencies & integrities – only guarantee “eventual”
consistency
— Some data (such as user comments) can tolerate
these drawbacks
— Some data (such as financial, transactional) cannot
— Enterprises conclusions:
− NoSQL & Big Data are good for business intelligences data
− Financial & transactional data still require relational databases
− Compliance requirements / regulations
8
9. The New World of Data Modeling with Relational
and Big Data
— The new enterprise data landscape:
− Different relational databases
− Distributed hadoop cluster with structured, semi-structured,
and unstructured data which is constantly changing
— Challenges to the data architects / modelers:
− Identify potential relationships between different data stores
− Automated way to track and update the unified view
— Data Modeling tools, such as ERwin, need to evolve
to present a single unified view of ALL enterprise
data

12. What We Learn So Far
— Most non-relational data store will be a simple entity / box in
ERwin
− Attributes in each non-relational entity include key indices and columns
− Supercolumns or nested structures can be expanded in the same entity
or depict as hierarchy
— Metadata are important:
− Describes the kind of information / data
− Structure of the columns in a supercomlumn
— There are relationships between non-relational data stores and
relational databases
— So far, we only investigated reverse engineering of data stores
into logical model. Forward engineering of logical model into
physical non-relational data stores may be useful
— We are not there yet, but a unified data modeler of relational and
Big Data is definitely possible
12
13. The Future of Data Modeling
— Presented a (but not the only) direction that data
modeling can be evolved to model both relational
and non-relational data stores
— Data explosion will continue and accelerate at a
much faster rate
— Business must rely more and more on collected data
to gather business intelligence to compete
— Role of data architect and modeler will become more
important – to analyze Big Data, enterprises must
first understand what they have!
