Understanding SQL Data Services Azure™: Overview, Features, and API Integration

DESCRIPTION

SQL Data Services (SDS) Azure™ offers a unique solution for database management that is not based on traditional RDBMS models. With a focus on flexible data storage, SDS allows users to utilize 50Gb of storage across authorities, with a maximum of 1000 containers per authority. The service supports both REST and SOAP APIs for seamless data manipulation, from creating to querying entities. This article explores the ACE containment model, administration tools, and provides insights on the capabilities and roadmap of Azure™ SQL Data Services for effective application development.

  1. SQL Data Services (SDS) Azure Services Platform

  2. Azure™ Services Platform

  3. Azure™ Services Platform

  4. Agenda • Database • ACE model • Datatypes • Administration and API (REST and SOAP interface) • Tools (Windows) • Roadmap

  5. So what is it? • Sql Data Services • A 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

  6. ACE Containment Model • Authority • Containers • Entities Container Entity Entity Entity Authority Entity Container LB

  7. Supported datatypes • Type system is W3 Xml Schema • string • boolean • dateTime • decimal • base64Binary • + • ……………………………………….. Blob Sql Data Services A database ..... However not a RDBMS!

  8. Administration and API • REST • SOAP

  9. 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>

  10. 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>

  11. 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}

  12. 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>

  13. 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}

  14. 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

  15. 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

  16. 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

  17. 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"

  18. SOAPQuery <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!
