Agenda

• Database• ACE model• Datatypes• Administration and API (REST and SOAP

interface)• Tools (Windows)• Roadmap

So what is it?

Sql Data ServicesA database ..... However not a RDBMS!

Current setup in CTP:• Each user will be allowed 50Gb of storage across all Authorities• 1000 Containers per Authority • 1Gb of Blob Entities per Container (up from 500mb)• 100mb of Flexible Entities per Container (up from 20mb)• Each Blob Entity will be capped at 100mb

Administration and API

REST SOAP

REST Create - HTTP Post

Authority:

<s:Authority xmlns:s="http://schemas.microsoft.com/sitka/2008/03/"> <s:Id>myCRMDatabase</s:Id></s:Authority>

Container:

<s:Container xmlns:s="http://schemas.microsoft.com/sitka/2008/03/"> <s:Id>myCustomers</s:Id></s:Container>

REST Create - HTTP Post (2)Entities:

<Entity xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:x="http://www.w3.org/2001/XMLSchema" xmlns:s="http://schemas.microsoft.com/sitka/2008/03/"> <s:Id>id234985798</s:Id> <kind xsi:type='x:string'>customer</kind> <firstname xsi:type='x:string'>Jens</firstname> <surname xsi:type='x:dateTime'>Jensen</surname> <status xsi:type='x:string'>Gold member<status/> </Entity>

Or

<customer xmlns:s='http://schemas.microsoft.com/sitka/2008/03/' xmlns:xsi='http://www.w3.org/2001/XMLSchema-instance' xmlns:x='http://www.w3.org/2001/XMLSchema' > <s:Id>id234985798</s:Id> <kind xsi:type='x:string'>customer</kind> <firstname xsi:type='x:string'>Jens</firstname> <surname xsi:type='x:dateTime'>Jensen</surname> <status xsi:type='x:string'>Gold member<status/> </customer>

REST Delete - HTTP Delete

Authority:

Not Supported!

Container:

https://{AuthorityID}.data.database.windows.net/v1/{ContainerID}

Entity:

https://{AuthorityID}.data.database.windows.net/v1/{ContainerID}/{EntityID}

REST Update - HTTP Put

Entity:

https://{AuthorityID}.data.database.windows.net/v1/{ContainerID}/{EntityID}

<Entity xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:x="http://www.w3.org/2001/XMLSchema" xmlns:s="http://schemas.microsoft.com/sitka/2008/03/"> <s:Id>7234985798</s:Id> <kind xsi:type='x:string'>customer</kind> <firstname xsi:type='x:string'>Jens</firstname> <surname xsi:type='x:dateTime'>Jensen</surname> <status xsi:type='x:string'>Gold member<status/>

<gender xsi:type='x:string'>Male<gender/> </Entity>

REST Retrive - HTTP Get

Authority:

https://{AuthorityID}.data.database.windows.net/v1/

Container:

https://{AuthorityID}.data.database.windows.net/v1/{ContainerID}

Entity:

https://{AuthorityID}.data.database.windows.net/v1/{ContainerID}/{EntityID}

SOAP - CRUD pattern

Metadata infomation (WSDL’s)

Access and authentication:

https://database.windows.net/soap/v1/

...imports messaging and CRUD pattern interface:

https://database.windows.net/soap/v1/schemas.microsoft.com.sitka.2008.03.wsdl

Query

General syntax:from e in entities [where condition] [orderby property 1 [,property 2, …]] select e

Comparison Operators: >, >=, <, <=, ==, != Logical operators: && (and), || (or),! (not) Syntax difference - mandatory system entity metadata vs entity properties:

from e in entities where e.Id == "id234985798" select e or

from e in entities where e["firstname"] == "Jens" select e

Query helpers

Ofkind():from e in entities.OfKind(”customer”) select e

Take(): (from e in entities where e[“firstname”] == “Jens" select e).Take(10)

Take(from e in entities.OfKind(“customer“) select e, 10) Join support:

from c in entities.OfKind(“customer“) where c[“firstname"] == “Jens" from o in entities.OfKind(“order“) where o[“customerId"] == c.Id select o

REST Query

Containers

All containers in Authority: https://{AuthorityID}.data.database.windows.net/v1/?q=

Container “customer”:https://{AuthorityID}.data.database.windows.net/v1/?q="from%20e

%20in% 20entities%20where%20e.Id==“customer"%20select%20e"

Entities

All entities in container:https://{authority-id}.data.database.windows.net/v1/{container-id}?q=''

Select specific entity:https://{AuthorityID}.data.database.windows.net/v1/{containerid}?

q="from %20e%20in%20entities%20where%20e.Id==“id23243532"%20select%20e"

SOAP Query

<wsdl:message name="ISitkaSoapService_Query_InputMessage"> <wsdl:part name="parameters" element="tns:Query" /> </wsdl:message>

<xs:element name="Query"> <xs:complexType> <xs:sequence> <xs:element minOccurs="0" name="scope" type="tns:Scope" /> <xs:element minOccurs="0" name="query" nillable="true" type="xs:string" /> </xs:sequence> </xs:complexType></xs:element>

...and the same query string as the REST examples!
