This document provides an introduction to big data. It defines big data as large and complex data sets that are difficult to process using traditional data management tools. It discusses the three V's of big data - volume, variety and velocity. Volume refers to the large scale of data. Variety means different data types. Velocity means the speed at which data is generated and processed. The document outlines topics that will be covered, including Hadoop, MapReduce, data mining techniques and graph databases. It provides examples of big data sources and challenges in capturing, analyzing and visualizing large and diverse data sets.
Databases are used to store and organize data for fast retrieval. They have several objectives like speedy retrieval, ordering, and conditional grouping of data. Database management systems (DBMS) help manage databases by defining entities, storage architecture, security, backups and more. Relational database management systems (RDBMS) are most common today and follow Codd's rules. Databases can be classified by usage (operational, data warehouse, analytical), processing type (single, distributed), storage type (flat file, indexed, trees), and content scope (legacy, hypermedia). Database contents include tables with rows and columns to store entity attributes and records. Tables have field/column definitions specifying name, data type, size and other properties
This document discusses issues, opportunities, and challenges related to big data. It provides an overview of big data characteristics like volume, variety, velocity, and veracity. It also describes Hadoop and HDFS for distributed storage and processing of big data. The document outlines issues in big data like storage, management, and processing challenges due to scale. Opportunities in big data analytics are also presented. Finally, challenges like heterogeneity, scale, timeliness, and ownership are discussed along with approaches like Hadoop, Spark, NoSQL databases, and Presto for tackling big data problems.

4. Deep roots at the intersection of HPC, databases and data science
Traction with telecoms, pharmas, hospitals and other scientific organizations
35 employees with domain experts across all applications and domains
Who we are
TileDB got spun out from MIT and Intel Labs in 2017
WHERE IT ALL STARTED
Raised over $20M, we are very well capitalized
INVESTORS
5. The Problem with “Purpose-Built Data Systems”
The Definition of the Universal Database
What the Database Community Missed
Architectural Decisions in TileDB
Proving Feasibility: Some Use Cases
The Future of Data Management
Agenda
7. And then there was light
We built a lot of sophistication around relational databases
Relational algebra + SQL
Roles, constraints, etc.
Row-stores vs. column stores
OLTP (transactional) vs. OLAP (warehouses)
Shared-nothing architectures
… and a lot more
Relational databases worked beautifully for tabular data
8. Big Data & the Sciences
In the meantime, the sciences have been generating immense amounts of data
This data is too big for traditional database architectures
This data cannot be represented very well with tables
Other database flavors (e.g., document) are not ideal either
Not all scientists like “databases” :)
Genomics
Imaging (satellite / biomedical)
LiDAR / SONAR / AIS
Weather
… and many more
9. The Cloud effect
As storage and compute got out of hand, cloud increased in popularity
Separation of storage and compute was inevitable
Cloud object stores were the obvious (cheapest) choice
Old database architectures did not work off the shelf
New paradigm: “lake houses”
Store all data as (pretty much) flat files on cloud stores
Use a “hammer” (computational framework) to scale compute
Treat data management as an afterthought and adopt “hacks”
10. The Machine Learning hype
Everybody wants to jump on the next sexy thing
Many new great frameworks and tools around ML
People started to like coding and building new great things
ML facilitated the advent of “Data Science”
Everyone thought that ML is a “compute” problem
In reality, ML is a data management problem
But there was an important mistake
11. And then there was mess
Too many file formats and disparate files lying around in cloud buckets
A metadata hell gave rise to “metadata systems”
Data sharing became complex and gave rise to “governance systems”
ML gave rise to numerous “feature / model stores”
Thousands of “data” / “ML” companies and open-source tools got created
Cloud vendors keep on pitching you hundreds of tools with funny names
“Data management” (and ML
became the noisiest problem space!
12. The Problem in a nutshell
Organizations lose time and money
Science is being slowed down
Organizations working on important problems are lost in the noise
Use a combination of numerous data systems, difficult to orchestrate
Or, build their own in-house solutions
There is tons of re-invention of the wheel along the way
Huge engineering overlap across domains and solutions
Scientists spend most of their time as data engineers
14. What makes a database Universal
A single system with efficient support for
all types of data (including ML
all types of metadata and catalogs
Authentication, access control, security, logging
all types of computations (SQL, ML, Linear Algebra, custom)
Global sharing, collaboration and monetization
all storage backends and computer hardware
all language APIs and tool integrations
“Infinite” computational scale
15. Benefits of the Universal Database
Future-proofness
Don’t build a new system, extend your existing one
No. More. Noise.
Single data platform to solve problems with diverse data and analyses
Single data platform for authentication, access control and auditing
Easy, global-scale collaboration on data and (runnable) code
Superb extensibility via APIs and other internal abstractions
Modularity and API standardization
Facilitates user creativity, preventing reinvention of the wheel
17. Why no one had built it
We are stuck in an echo chamber
All cloud vendor marketing campaigns are around purpose-built systems
Some purpose-built systems had success
Universality intuitively seems like a long shot (and a LOT of work)
Tons of funding currently poured on incremental data solutions
The most promising data structure got overlooked!
Other solutions used it without traction
Arrays were never used to their fullest potential
This structure is the multi-dimensional array
18. How arrays were used
Each cell is uniquely identified by
integral coordinates
Every cell has a value
This is called a dense array
Pretty good for storing images, video, …
… but not good for tables and many more!
A multi-dimensional object comprised of cells
19. Pros of dense arrays
Dense array engines provide fast ND slicing
Dense arrays do not materialize coordinates
Slicing is done via zero copy close to optimally
In a table, we’d need to store the coordinates
Then a SQL WHERE condition on coordinates
Waste of space and query too slow
Dense array engine Tabular format + SQL
20. Cons of dense arrays
No string dimensions
No real dimensions
No heterogeneous dimensions
No cell multiplicities
Hence, definitely no table support
No efficient sparsity support
21. A dense array database is not enough
Too limited if it can’t store tables and other sparse data
Remember, not everyone likes “databases” (the way they are perceived today)
Scientists opted for array storage engines and custom formats / libraries
Therefore, they missed out on the other important DB features
Full circle, back to the mess
22. The Lost Secret Sauce | The Data Model
Heterogeneous dimensions (plus strings and reals)
Cell multiplicities
Arbitrary metadata
Dense array
In addition to dense arrays
Native support for sparse arrays
Sparse array
23. The Lost Secret Sauce | The Data Model
Arrays give you a flexible way to lay out the data on a 1D medium
Arrays also allow you to chunk (or tile) your data and compress, encrypt, etc.
Arrays provide rapid slicing from the 1D space, preserving the ND locality
End result:
Efficient, unified storage abstraction
Can now build APIs, access control, versioning, compute framework, etc.
24. The Lost Secret Sauce | The Data Model
Sparse array
Dense vector
Dataframe
Arrays subsume dataframes
25. The Lost Secret Sauce | The Data Model
What else can be modeled as an array
LiDAR 3D sparse)
SAR 2D or 3D dense)
Population genomics (3D sparse)
Single-cell genomics (2D dense or sparse)
Biomedical imaging (2D or 3D dense)
Even flat files!!! 1D dense)
Time series (ND dense or sparse)
Weather (2D or 3D dense)
Graphs (2D sparse)
Video (3D dense)
Key-values (1D or ND sparse)
26. The Lost Secret Sauce | The Compute Model
Take any algorithm from any application domain and remove the jargon
This algorithm can be split into one or more steps (the tasks)
Each task typically operates on a slice of data
This task graph engine should be part of
the database with an exposed API
Some tasks can work in parallel, some cannot (due to dependencies)
We can build a single task graph engine, for any arbitrary compute
27. The Lost Secret Sauce | Extensibility
Data slicing and each task should be performed in any language
A good bet is to build as much as possible in C
Although 90% of the data management code is the same across applications
Each scientist has their own favorite language and tool
APIs should still be written in the application jargon
Should support multiple backends and computer hardware (existing and new)
There is no chance that the database can offer all operations built-in
Operations should be crowdsourced and shared
The database should provide the infrastructure to facilitate that
28. The Lost Secret Sauce | Summary
The foundation for a universal database:
array data model + generic task graphs + extreme extensibility
