More stuff

Have been developing software since i286 days Educational CD-ROMs If a mistake, had to redo the entire run Started looking at ways to have dynamic data Web development

Cold Fusion (yuck), PHP (yikes), ASP.NET (the promised land)

Met David Robinson on Code Trip (Feb 08) The rest is history

SQL Data Services - Introduction

Agenda

2. What is SDS

3. How to setup the development environment

SQL Data Services - Introduction

1. SDS is a component of SQL Services

2. Integrated into the “cloud”

3. Provides database and querying

4. Flexibility

5. Scaling

6. Developer agility

SQL Data Services - Introduction

SDS is built on SQL Server and Windows Server

2. Quickly build and extend applications

3. Low cost management with high scalability

4. Reliability, and security features

SDS – Setting up the environment

Download Azure Services Training Kit www.microsoft.com/azure/trainingkit.mspx Contains Hands-on-labs (HOLs) for:

Windows Azure .NET Services Live Services SQL Services

SDS – Setting up the environment

Sign up for the SDS Public CTP http://go.microsoft.com/fwlink/?LinkID=133905&clcid=0x409 Sign up is free, but will ask for CC for verification

Create a Solution Name and Password Name of solution is the username when logging into

system via code

Authorities, Containers, Entities

Authorities, Containers and Entities, Oh My

2. SDS data model is based on this concept

3. Provides flexible schema

4. Easy to create data structures

Authorities, Containers, Entities

Authorities

2. Topmost level of the hierarchy anontypes-01

3. DNS name https://anontypes-01.data.database.windows.net/v1

Maps to specific data center Is a unit of geo-location

Authorities, Containers, Entities

Containers

2. Each container has unique id associated

3. Store the data contained in the application

4. Cannot be in a different geo-located Authority

5. Can contain homogeneous or heterogeneous data

Authorities, Containers, Entities

Entities

2. Actual bits of data stored in container

3. Stores any number of user-defined properties/values

4. Retrieved, added, updated, deleted

5. Partial updates are not supported

6. Entire entity is replaced in container when updated

Homogenous/Heterogeneous Data

Homogeneous data is similar to a database table, in which all entities are of the same kind

Books container stores “book” entities Highly structured applications should use

Heterogeneous data contains all types of entities MyOffice container stores “books”, “supplies”,

“furniture” Allows for querying across all entities in parent

container

Flexible Entities

1. Key concept of SDS

2. XML fragment with one element per property value.

3. Value restricted to simple scalar type of string String, binary, Boolean, decimal, datetime

4. Fixed metadata properties – Id, Version, Kind1. Version. New version assigned with each update

2. Kind. User-defined, identifying the entity type

Anonymous Types

A new podcasting website featuring the little known development geeks

Site runs on a hosted server Data is hosted on SQL Data Services Leads to differences in how we work with data When using REST, return types are XML Need to use LINQ

Differences to remember

An Entity is like a property bag – keys/values Each Entity in a Container can have a different

structure Different paradigm than when working with

database tables There is no “primary key”, instead an “EntityID”

User defined value

Containers

Can contain heterogeneous, homogeneous, or flexible entities

For this project decided to have four Containers at_page at_podcast at_podcastdata at_guest

Site structure

Administer text data Upload and administer BLOB’s (podcasts)

Demo only shows uploading – not streaming down

Standard ASP.NET Membership, Roles, Authentication for Admin pages

Classes for different aspects of site functions Pages, Podcasts, Guests, Configuration, Utilities

Using REST

POST (Insert, Create) PUT (Update) GET (Retrieve) DELETE (Delete)

Page Administration

Insert, Save, Edit, Delete Page code creates XML passed to the class Methods

SelectPages() SelectPage() InsertPage() UpdatePage() DeletePage()

Make sure to HtmlEncode strings going in HTML chars will mess things up with validity of the XML

Demo

Web site Page administration

Uploading PodCasts (BLOBs)

Uploading of BLOBs is possible, but can only send the object, no other data

Create two XML strings PodCast

EntityId, Container, FilePath

PodCastData Meta and other data about the PodCast EntityId,Title, RunTime, Guest, Publish Date, etc.

Since two different containers, can have same EntityId

Uploading PodCasts (BLOBs)

Two step process First insert the Meta data

Title, Guest, Description, etc.

If successful, upload the PodCast

Demo

Public facing side

One Master Page Navigation, PodCast List

One Content Page Page Content for different “pages”

Demo

Setting Navigation

Demo

Setting Page Content

Demo

Get All PodCasts Uses Join between Containers so that we can get

data back on the Guests as well

Demo

Get Single Uses Join between Containers Uses Where to get specific Pod Cast
