How To Be Normal - A Guide For Developers

scoundrel — Thu, 17 Apr 2008 19:10:04 GMT

At some point in every software project involving a database it becomes necessary for the developers who created (or inherited) the project to step back and take a look at their database. Many projects have a database schema that has evolved over time, with columns added here and tables added there, increasing complexity and often adding redundancy. Super-tables grow with more and more columns making ALTERs slow and backups difficult.

In this session MySQL author and speaker Mike Hillyer will guide the audience through the principles of database normalization and review some common normalization scenarios encountered by many application developers.

Topics include:

What is normalization and what are its benefits?
What are the normal forms?
- First Normal Form
- Second Normal Form
- Third Normal Form
- And so on…
Normalization Scenarios
Relationships and Joins
How Much is Too Much?

This session is intended for a beginner to intermediate audience and is applicable to developers and administrators who deal with database design.

C++ Stylistics

scoundrel — Wed, 02 Apr 2008 18:02:40 GMT

Google Tech Talks
March, 5 2008

ABSTRACT

Both by accident and by design, C++ supports a number of different styles and approaches to programming. Its evolution from C gives it obvious support for a procedural systems programming style based on C idioms, but past, present and future language support opens up a wealth of other approaches and idioms, including object-oriented programming, generic programming and some elements of functional programming.

This diversity is both a strength and a weakness. It can lead to code that is crisp and well matched to its problem. But it can also lead to code that is at best considered an exercise in groundless post-modernism or, less favorably, an unmaintainable and incoherent mess.

This talk examines some of the styles and approaches, including their key strengths and accidental complexities, as well as consequences of and techniques for combining them.

Algorithms for Data Management and Migration

scoundrel — Mon, 24 Mar 2008 16:11:11 GMT

Google Tech Talks
January, 23 2008

ABSTRACT

I will describe some algorithms for addressing some fundamental optimization problems that arise in the context of data storage and management. In the first part of the talk we will address the following question: How should we store data in order to effectively cope with non-uniform demand for data? How many copies of popular data objects do we need? Where should we store them for effective load balancing?

In the second part of the talk we will address the issue of moving data objects quickly, to react to changing demand patterns. We will develop approximation algorithms for these problems.

The first part of the talk is joint work with Golubchik, Khanna,Thurimella and Zhu. The second part is joint work with Kim and Wan.
