Google I/O 2008 - App Engine Datastore Under the Covers
Under the Covers of the Google App Engine Datastore
Ryan Barrett (Google)
Ever wonder why you can't do joins in the Google App Engine datastore? Why your app is seeing deadlines so often? Why it's so hard to tell whether a query will need an index? Why we offer both parent/child relationships and reference properties? Or why list properties don't seem to make any sense at all? This talk will explain how the datastore itself works, why these seeming peculiarities (and many others!) exist, and what you can do about them.

Google I/O 2008 - Working with Google App Engine Models
Working with Google App Engine Models
Rafe Kaplan (Google)
Google App Engine Datastore Models have a lot in common with existing frameworks such as ActiveRecord and the Django database API. However, there are significant differences because of how the App Engine Datastore works. This talk will introduce the App Engine Model Framework and show how to use it to represent real-world information. Learn about the various types of information you can store using the Model and how to create relationships between entities. Beyond the basics, you can learn how to extend the model to store custom data types. In the course of this demonstration, we will build a model to represent a common and practical use case - User preferences.

Data Integration - 1
What is data integration (DI)? At present DI is buzz word in industry and every organization, in one form or another has DI intitiative. There are few basic concept which should be understood and socialized with the organization before starting the DI intiative and make the DI intiative successful.
DI is part of EDW life cycle. And it is very important to understand at what phase of EDW life cycle DI should be done. DI should be more driven from business rather than techinical requirements. Business community should be full invloved in the DI initiative. Data Governance plays very critical role in DI initiative.
First phase of EDW life cycle is to collect differnt source system data ( internal and external) and store in EDW data store in standardize format. At this data store, data should also be cleanized, enable point in time analysis on source system data. In this data store ( which is also referred as ODS or acquisition layer) data is not transformed. Data is stored in source facing structure. Business comunity should be using this data to get any source related information from this data store. The objective should be to get business community confidence in collected data and they should provide feedback about the data. Datamart may also be build from this layer to support any analytical reporting requiremen before DI layer is available.
In the later part of EDW life cycle, once EDW has business community confidence, DI initiative should be taken. This DI initiative should come as requirement from business community.

DEMO: EMC Rep Manager Enables Instant VMFS Backup & Restore
Learn how EMC Replication Manager can dramatically reduce the time and impact to provide full VMFS datastore recovery capability by leveraging EMC array snapshot technology.
VMware users often struggle with how they can most effectively and efficiently backup their VMware Infrastructure. With entire operating systems being encapsulated into a few simple files, many administrators want full OS level recovery in addition to traditional file level recovery options. The best approach is to have a solution that supports all three critical data levels: Full VMFS datastore, Single Virtual Machine and in Guest file level recovery.
