  39. 39. Microsoft Azure SQL Database Architecture • Architecture • There are four different levels of abstraction, which work together to provide a relational database for your application:  Client layer  Services layer  Platform layer  Infrastructure layer • SQL Azure offers only DTS endpoint • For each Windows Azure SQL database instance there was created 3 copies of SQL
  40. 40. Windows Azure SQL Database Architecture • Azure SQL Database Disadvantages Azure SQL Database does not support the following functions of the database • Service Broker • HTTP access • CLR stored procedures
  41. 41. Microsoft Azure SQL Database Architecture • Azure SQL Database Disadvantages  Azure SQL Database support spatial data types, but developers need to deploy libraries with spatial CLR types with their applications. Windows Azure has no installed predefined SQL spatial data types  Azure SQL Database does not support the following functional features • Distributed queries • Distributed transactions • Any SQL query and views that change or get physical information resources
  42. 42. Microsoft Azure SQL Database Architecture • Azure SQL Database Spatial Data Support  Microsoft Azure SQL Database supports enhancements to spatial data types: • new and updated methods and aggregates for geometry and geography; • improved precision, enhancements to the geography type; • spatial performance improvements; • spatial helper stored procedures; • support for persisted computed columns; • changes in the client-side spatial programming library.
  43. 43. Microsoft Azure SQL Database Architecture • Azure SQL Database Spatial Data Support  Microsoft Azure SQL Database spatial data types issues: prior to 2012 Azure SQL Database didn’t support : • Most of stored procedures, related to spatial types • Most of Boolean operations • Spatial aggregates didn’t work correectly
  44. 44. Azure SQL Database Federations • DB Scaling solutions: Scale UP vs. Scale OUT  Scale UP: • This approach relates to improving the hardware solution of the DB - faster processor, more RAM, faster Hard Drive • A single SQL Azure database can contain up to 150GB • NewDB Editions in Azure (Preview): – Standard (250 GB) – Premium (500 GB)
  45. 45. Azure SQL Database Federations • DB Scaling solutions: Scale UP vs. Scale OUT  Scale OUT: • The Scale OUT approach relates to implementing a DB solution in which the I/O process will be distributed across multiple DB partitions. • Scale OUT options: – Table partitioning – Master/Slave configurations – Cluster Computing – Sharding
  46. 46. Azure SQL Database Federations • DB Scaling solutions: Scale UP vs. Scale OUT  Scale OUT: • Table partitioning – a large table is split into two or more physically separate partitions • Master/Slave configurations – one database which is called “Master” and multiple databases called “Slaves”. • Cluster Computing – Similar to the Master/Slave. In such scenario one of the read-only nodes becomes the new “Master” if the “Master” fails • Sharding
  47. 47. Azure SQL Database Federations • Scale UP vs. Scale OUT  Scale OUT: • Sharding: – “Sharding” or “Shared nothing” – the application operates with “Shards” which can be physically separate databases. – there are queries which run inside the shard and queries which are distributed across multiple shards (you should minimize it)
  48. 48. Azure SQL Database Federations • Sharding  SQL Azure Federations: • Azure Federation is a Sharding technology which allows distributing the DB transactions across multiple databases which are called Federation Members. – Federation object – Federation Key – Federation Member – Atomic Unit
  49. 49. Azure SQL Database Federations • Sharding  SQL Azure Federations: – Federation Root: Refers to the database that houses federation object. – Federation Distribution Key: This is the key used for data distribution in the federations. – Federation Atomic Unit: Represent all data that belongs to a single instance of a federation key. – Federated Tables: Refer to tables that contain data that is distributed by the federation. Federated tables are created in federation members and contain a federation distribution key annotated with the FEDERATED ON
  50. 50. Azure SQL Database Federations • Horizontal Partitioning and Vertical Partitioning – Horizontal partitioning, likes you use a knife to cut the table horizontally, which means split the table by rows – Vertical partitioning means split the table by columns
  51. 51. Azure SQL Database Federations • SQL Azure Federations – utilize the horizontal partitioning to split the tables in multiple databases. – make sure that all records in the tables that referred to the same ID must be in the same partition
  52. 52. Azure SQL Database Federations • SQL Azure Federations A federated database contains three types of table: – Federated – Reference – Common A federated table is created by appending FEDERATED ON to a CREATE TABLE statement. CREATE TABLE (…) FEDERATED ON (Customerid = custId)
  53. 53. Azure SQL Database Federations • SQL Azure Federations and Spatial Support – Geography and geometry types cannot be used as the data type of the column that a table is federated on; however they can be part of the federated table. There are no other limitations on using spatial data with federations. – After a SPLIT or DROP operation, spatial indexes stay consistent and intact in the destination federation members
  54. 54. Migrating Spatial Data to SQL Azure • SQL Server 2008/2008 R2  Microsoft SQL Management Studio for SQL Server 2008/2008 R2 does not support the transfer of spatial data in Azure SQL Database • SQL Azure Migration Wizard: http://sqlazuremw.codeplex.com/
  55. 55. Migrating Spatial Data to SQL Azure • SQL Server 2012 / 2014  Microsoft SQL Management Studio for SQL Server 2012 / 2014 does supports the transfer of spatial data in Azure SQL Database
  56. 56. Migration of systems with spatial data in Azure SQL Database Create a new Azure SQL database Database migration – migrate your databse from the local SQL Server to SQL Azure Add a new Windows Azure Storage Account and Web services Add web project role in the decision Change settings in the Web.config and ServiceReferences.ClientConfig Publish Windows Azure Cloud Service
  57. 57. Using Spatial Data in Microsoft Azure SQL Database • Processing of spatial data using .NET in Windows Azure SqlCommand sqlCommand = new SqlCommand(); sqlCommand.Connection = sqlConnection; sqlCommand.CommandType = System.Data.CommandType.StoredProcedure; sqlCommand.CommandText = "get_WorldData"; sqlConnection.Open(); SqlDataReader reader = sqlCommand.ExecuteReader(); if (reader != null) while (reader.Read()) { Dictionary<string, string> valueDictionary = new Dictionary<string, string>(); for (int i = 0; i < reader.FieldCount; i++) { valueDictionary.Add(reader.GetName(i), reader.GetValue(i).ToString()); } list.Add(valueDictionary); } ....
  58. 58. Using Spatial Data in Microsoft Azure SQL Database • Using Entity Framework 5 and later versions List<SpatialPoint> multiPoints = new List<SpatialPoint>(); var numPoints = country.geom.Envelope.ElementAt(1).PointCount; for (int i = 1; i <= numPoints; i++) { SpatialPoint pnt = new SpatialPoint((double)(country.geom.Envelope.ElementAt(1). PointAt(i).XCoordinate), (double)(country.geom.Envelope.ElementAt(1).PointAt(i). YCoordinate)); multiPoints.Add(pnt); } SpatialRect rect = multiPoints.GetBounds();
  59. 59. Using Spatial Data in Microsoft Azure SQL Database • Windows Azure Web Site and spatial data Creating a Windows Azure Web Site
  60. 60. Using Spatial Data in Microsoft Azure SQL Database • What libraries to use? Microsoft.SqlServer.Types.dll • (managed) .NET library • Program Files(x86)Microsoft SQL Server110SDKAssemblies SQLServerSpatial.dll / SQLServerSpatial110.dll • (unmanaged) C++ library • WindowsSystem32
  61. 61. Using Spatial Data in Microsoft Azure SQL Database • Getting libraries Project –> Add Existing Item WindowsSysWOW64 -> msvcp110.dll and msvcr110.dll files (Visual Studio 2012) or msvcp100.dll и msvcr100.dll - required for spatial data (Visual Studio 2010) .
  62. 62. Using Spatial Data in Microsoft Azure SQL Database • Getting libraries  Set the properties of msvcp100.dll, msvcr100.dll and SqlServerSpatial.dll / SqlServerSpatial110.dll to “Copy to Output directory = Copy always”
  63. 63. Using Spatial Data in Microsoft Azure SQL Database • Microsoft Azure and Entity Framework  Deploying Spatial Data Types to Microsoft Azure • In order to use spatial data types on Windows Azure you will need to deploy the Microsoft.SqlServer.Types assembly with your application. The easiest way to do this is to install the Microsoft.SqlServer.Types NuGet package in your application. PM> Install-Package Microsoft.SqlServer.Types
  64. 64. Using Spatial Data in Microsoft Azure SQL Database • Microsoft Azure and Entity Framework  SQL Azure Federations • The current release of Entity Framework can be used to work with SQL Azure Federations, however a federated database cannot be created by the Entity Framework.
  65. 65. Demo
  66. 66. Spatial Data and Microsoft Azure Storage • Is Azure Storage NoSQL ? • Using spatial data in the Microsoft Azure Blob Storage • Accessing the Windows Azure Storage is done via a storage account. A storage account can have many blob containers. A container is a user-defined set of blobs that has only properties, which include a list of the blobs it contains. Containers don’t store data directly.
  67. 67. Spatial Data and Microsoft Azure Storage • Windows Azure Blob Storage • Windows Azure Blob Storage Concepts
  68. 68. Spatial Data and Microsoft Azure Storage • Microsoft Azure Blob Storage  Blob URL • http://<Account>.blob.core.windows.net/<Container>/<BlobName>  URL: • http://sally.blob.core.windows.net/music/rock/rush/xanadu.mp3  Types of Blobs – Block Blob – Page Blob
  69. 69. Spatial Data and Microsoft Azure Storage • Steps to Implement Azure Application Reading Shapefiles from Blob Storage – Implement a WCF to upload and download files, using Windows Azure Blob Storage. – Add in the client application (ASP.Net / Silverlight ) XamMap component. – Implement shapefile loading from Isolated Storage to XamMap. – Create a new Windows Azure Storage Account and a Hosted Service (if you are using a Windows Azure Account). – Add a Web Role project in Solution – Edit settings in ServiceReferences.ClientConfig . – Publish the Windows Azure Cloud Service
