ABSTRACT:

 

In 2015, for a few hundred dollars a year, you can have a personal

petabyte database (PetDB) that you can access from any point of

connection, with any device. It stores and organizes any kind of digital

data you want to have, without losing structure or information. All this

data is queryable and it is arranged by type, content, structure,

association and multiple categorizations and groupings. You can also

locate items by when or how you encountered them, what you have done with

them, where you were when you accessed them.

 

What could you fit in a personal petabyte store? Some possibilities:

 

*The contents of every book and magazine you ever bought.

*Every web page you've ever visited.

*Every email you've ever sent or received, including all attachments.

*Every version of any piece of software you have ever used.

*Maps and images of every place you have ever been.

*Descriptions and price lists for every kind of product you might want

  to buy-a "universal, personal catalog."

*Portions of the web you might want to browse, including snapshots at past

  points of time.

 

Your PetDB doesn't appear to reside on any particular computer-you are

never on the "wrong" machine to access it. More importantly, you don't

have to take any explicit action to insert data into you PetDB; your PetDB

doesn't appear to have an "outside" where data is concerned. Thus your

PetDB is also your personal Internet portal: your evolving and customized

view of all on-line digital data.

 

The PetDB isn't predicated upon some massive improvement in holographic

memory technology or DNA-based storage units. Rather, it is an example of

what could be done with a new generation of software infrastructure we

term Net Data Managers (NDMs). NDMs are a departure from the capabilities

and structure of current database management systems. They focus on data

movement, rather than data storage, working equally well with live streams

of data as with files in secondary storage. They will be capable of

storing data of arbitrary types, without a matching database schema having

been defined previously. They will efficiently execute queries over

thousands or tens of thousands of information sites. They will locate and

select data items by both internal content as well as a variety of

external contexts. NDMs will also support monitoring rapidly changing

information sources in a way that scales to thousands or even millions of

triggers.

 

This talk lays out the requirements for Net Data Management, and reports

on the research directions being pursued by the NIAGARA project, a joint

undertaking with David DeWitt and Jeffrey Naughton at the University of

Wisconsin. I will focus in particular on incremental query processing, the

merge operator and some ideas about stream semantics.
