Tools for working with databases

Mike Zeff
Developer Evangelist
Developer & Platform Strategy Group
Microsoft NZ


Or how to make the database guy part of the development team.

Visual Studio Team System

Team Edition for Database Professionals

  • Expand to database teams
  • Manage database change
  • Database Testing
  • Database Deployment

What we heard from customers

(or “why did we build it…”)

  • Managing data base change is hard…
    • A rollback means a LONG night
    • Development teams can end up working with out-of-data versions
    • Finding errors at the end of the development cycle
  • Disconnect between development and database teams

Conceptual Overview

  • Schema change now managed in VS Team System and TFS
  • Production Database is now “One version of the truth” only for Data
  • “One Version of the truth for Schema” is Under Source Control

Creating a Database Project

  • Core concept: offline database development
  • Simply a series of files collected together into a single logical collection
  • The files represent the truth of your schema
  • Can be included in complete solution
  • Can be stored in source control such as Team Foundation Server for versioning
Offline Development
  • Import database schema to populate project from production
  • Nothing changes until deployment
  • A couple of other points, but Mike was too fast

Demo Summary
  • Import schema from existing database
  • Database project is created as a series of .SQL files.
  • Some more, but he’s too fast.

Isolated Iterative Development

Benefits of this Approach
  • Managed, project oriented evolution of database schema
  • Application code and database
  • Too fast
Managing Change
  • Changes are local to the project
  • Project can be compared with database
  • All elements can be managed under version control
  • Template driven
    • Version specific Microsoft SQL Server 2000 or SQL Server 2005
Working with the Project
  • Add new elements
  • Too fast
  • Bring the power of refactoring to SQL
  • Update all dependent objects in a database project
  • Make an atomic change, see preview
  • Rename
Demo Summary
  • All changes occur offline, local to the project
  • Changes can be compared to database
  • Refactoring can update all dependent objects
A Rollback Means a LONG night
  • Unit testing helps ensure that changes do not break existing code
  • Unit test designer is SQL focused
  • Work in the language of your choice: T-SQL, VB, C#
  • Builds on existing Team Test unit Test functionality

What We Can Test

  • Stored Procedures
  • Functions
  • Triggers
  • Arbitrary SQL
  • Too fast
Test Data
  • To create a solid foundation for testing we support data generation
  • Deterministic – always generate
  • Too fast
Demo Summary
  • Use of Regular Expressions to limit generated test data
  • (he couldn’t get the RegEx to validate an email address)
  • Can specify number of rows to generate (up to 1 million?)
  • Can specify ratio of rows to related tables
  • Standard Visual Studio build task
    • New versus update builds
    • Project properties for builds
    • Scheme compare for builds
  • Configurations
  • Pre/Post Deployment scripts
  • Build results in SQL script file
  • Deploy
Build Cycle
  • Can also be used in a “continuous” environment

Deployment Summary

  • Deploy using .SQL file
  • Too fast

The Future of Data interaction


Data != Objects

  • Fix the impedance mismatch among different data domains
  • Focus on the needs of the application not bridging disparate data representations
  • Build on general purpose language features in C# 3.0 and ????
.NET Language Integrated Query (LINQ)
  • LINQ enabled data sources
  • LINQ enabled ADO.NET
    • LINQ to SQL
    • LINQ to Datasets
    • LINQ to entities
  • LINQ to Objects
  • LINQ to XML
.NET Language Integrated Query framework
  • Too fast
Querying relational data
  • current way (SqlCommand, SqlConnection, DataReader)
  • LINQ way (Define [Table], and use in code as a first-class object).

Building Composite Applications

Jeremy Boyd


Lots of ground to cover!

New concepts, code!

Look for code, samples and presentation downloads



Composite Applications

  • The whole is greater than the sum of its parts
  • Composed of a number of discrete and independent pieces, aggregating this functionality through a software interface.
  • Break free from “silo” issues
  • Lower cost of development
  • Consistency
Tradition Applications
  • An encapsulated system providing its own self sufficiency
What’s enabled all this?
  • Services
  • Software over services
    • Lightweight
    • Loosely coupled
    • 3 tier architecture
  • Result: Reuse of software!
Traps to watch for
  • Maturity for integration
    • Must be able to leverage services for direct integration for greatest benefit
  • External Trust
    • External data lives in the cloud
    • Reliance on provider for business operations
Example: Exchange Server 2007 is used by
  • Outlook
  • Outlook Web Access
  • Outlook Voice Access
  • Outlook Mobile
Background Motion
  • Lightweight build: 3 weeks
  • Consumes resources from
    • Flickr
    • Soapbox
    • GeoTagIt
  • Also publishes services and data
  • Presentation Layer = ASP.Net 2.0 & AJAX
  • Business Layer = Content Service, controllers & Model
  • Resource Layer = Service Proxies & LINQ to SQL Server
But How?
  • Start with the problem e.g. Provide a community site to provide content for DreamScene
  • Focus on the interface
  • Work out who is already offering functionality
    • Flickr works well for images
    • Soapbox works well for videos
We already had great tools
  • .NET 2.0 and .NET 3.0 Frameworks
  • ASP.Net AJAX
  • Composite Web Block
  • Enterprise Library
  • Don’t forget about 3rd party!
    • RSS Toolkit
    • Lucene.NET
    • 2 way data-binding
Some tips from the Background Motion build
  • WebDataBinder
    • DataBinder.DataBind()
    • DataBinder.Unbind()
  • Microsoft.Practices.EnterpriseLibrary.Validation
    • [RequireValidator]
    • Presenter.Save()

Supervising Controller (MVP)
  • View (GET http://site/pages.aspx)
  • Presenter (View is based on the PageBase class which wires it up to the Presenter)
  • Model (View can work with the Model but calls back to Presenter to perform process flow)
  • “Factor the UI into a view and controller where the view handles simple mapping to the underlying model and the controller handles input response and complex view logic.” Martin Fowlerwww.martinfowler.com
  • Cleanly separates UI process form binding/event logic
  • Improves testability
Dependency Injection
  • Establish a level of abstraction via a public interface, and remove dependency on components by (for example) supplying a plug-in architecture – Wiki
  • Allows for loose coupling
  • Abstraction through interfaces
  • Composite Web Block uses
  • ServiceLocator approach
Service Locators
  • I need an instance of IDataLayer class! (Consumer to Interface)
  • I can ask the ServiceLocator to give me an instance of IDatalayer
  • ServiceLocator holds an instance of Factory <IDataLayer>
  • Factory <IDataLayer> assembles a Concrete class instance
  • Concrete instance is returned to the Consumer
  • Consumer always calls through the IDataLayer interface
So What?
  • Solid foundation leads to flexibility – supports change!
  • Lower development complexity – modularity!
  • Testability of solution
    • More effective integration
    • Shorter cycles
    • Always building working code!
Unit Testing…
  • Create a separate library (project in the solution)
  • NUnit – a free testing framework
  • Define [Test] methods
    • Assert.IsFalse(contribution.ValidationResults.IsValid);
    • (do some work)
    • Assert.IsTrue(contribution.ValidationResults.IsValid);
  • Where might these be useful?
    • When a field length changes, the Unit Test will fail the Validator.
    • Helps save you a lot of time by capturing these types of failures
Continuous Integration
  • Developer checks in to source control
  • The BuildServer monitors the source control
  • The BuildServer builds the application
  • The BuildServer runs the unit tests
  • The BuildServer notifies whether all tests passed
  • External from this application
    • Active Directory
    • Web Services
    • Legacy System
  • Contract based consumption
    • Loose coupling
    • Flexibility in plug and play
But how?
  • Windows Communication Foundation
  • The Unified Framework for rapidly building service oriented applications
  • Building block for building Connected Systems
  • Designed around messages!
  • Full standards/specifications support (WS-* oriented)
  • Provide consistent API regardless of messaging requirement
  • Part of .Net 3.0 Framework
Software + Services
  • ASP.NET AJAX. The free framework for quickly creating a new generation of more efficient, more interactive and highly personalized Web experiences
  • Building a mash-up using ASP.NET AJAX
  • Web Service can output AJAX (JavaScript)!
AJAX with Services
  • ASP.Net AJAX allows native call
  • Too fast

Call to Action
  • Read about Patterns
  • Look at Unit Tests and CI http://ccnet.thoughtworks.com
  • Download the Composite Web Block
    • And the Validation Block
    • And the Enterprise Library
  • Publish services in your enterprise to allow composite applications to flourish!

Wellington SQL Server User Group meeting

Venue: Microsoft, Level 12, Mobil on the Quay, Lambton Quay, Wellington.

Time: Thursday 8 March 2007 @ 6pm

Who: Rob Hawthorne

What: Disk Management

Disk Types

  • IDE
  • SATA
  • SCSI

Disk Management

  • SAN - Best for Enterprise Class environments
  • NAS - Best for Medium Class environments and can include:
    • snapshot
    • File & Print management functions
    • Medium - high performance
    • Good levels of redundancy
    • Reduced scalability
  • iSCSI
    • a new technology
    • SCSI over IP networks
    • Some hardware devices, but mostly software based
    • Doesn't care about the disks
    • Cheap remote mirroring solutin
    • Slow! Need a fast network (1GB min)

Performance Issues

There are 3 major I/O performance factors:

  • I/O bandwidth: The aggregate bandwidth, typically measured in megabytes per second that can be sustained to a database device.
  • I/O latency: The latency is...
  • I/O something else: I missed before he took away the slide.

Scalability limits:

  • Database performance is limited by maximum Transaction log throughput, only ONE possible transaction log per database!
    • disk I/O
  • can be resolved by:
    • Multiple spindles

Disk I/O:

  • Determine i/o pattern
    • Writes
      • Transaction Log (~100% sequential)
      • Lazy writer (random)
    • Read
      • Random vs. Sequential
  • Establish disk I/O baseline or SLA outside SQL Server, using:
    • SQLIOSIM or IOMeter (Interl, public domain)
    • Special cases:
      • Transaction log
      • 1 tempdb file for each cpu
      • Max Paalle lBCP load = 1 BCP / CPU
        • Into SQL Server 005 partioned tables

I/O Bottlenecks

  • Are typically easy to find
  • Be very careful with the transaction log
    • Beyond 12 to 15 spindles doesn't buy much
    • Keep on separate physical disks for recovery
    • make RAID 10
  • Beware of write cost on RAID5:
    • In RAID 5 each write has to logically read old data + old parity (to compute parity) and write new data and new parity
    • Each RAID 5 write = 2 READS + 2 WRITES!
      • However: disk guys work real hard to optimize this
    • Recent bulk load tests showed >50% degradation comparing RAID 0+1 vs. RAID 5

Optimizing for the Log

  • Profile the log disk
    • How many writes / second can your disk sustain?
  • Keep the log disk purely for the log
    • Keeps the disk heads writing sequentially minimizing seeks
  • Beware of unprotected write back

Base practice for SQL Server and Disks

  • Separate logs, Data, TempDB, Indexes and System DBs, Pagefile an OS
    • Nothing new here - Make better use of fileGroups
    • Watch for TempDB usage in 2005
    • Table partitioning can change the game!
    • Make sure Model D B has settings to persist
  • Auto-grow can be very harmful to system performance
    • Understand the app!
    • Watch for growing logs and data files in DMV (Dynamic management views)
  • Formatting
    • 64KB as a general recommendation
    • SQL uses 8KB pages
    • Read and write 8 x 8KB pages
    • Use DISKPAR.exe (no spelling mistake, diskpar is name) to align disk sectors
  • Battery-backup controllers are generally best
  • Speed of disk drives i.e. 20 or 15K RPM)
    • Faster = Better for performance
  • Disk controllers need to be configured to align with application profile (understand the app!)
    • Read vs. Write
  • Sector sizes
  • Paging will cause performance issues
  • Row-Overflow will cause PageSplits
    • Understand the app!
    • Row-Overflow > 8,060 bytes per row (8KB)
    • varchar, nvarchar, varbinary, sql_variant


  • Understand the app!
  • Apply common-sense
  • Buy the best you can afford
  • Read the whitepapers
    • SQL Server 2000 I/O Basics
    • SQL Server 2005 I/O Basics Chapter 2
  • If suffering performance issues, identify if disk is cause (i.e. high CPU could be disk related)
  • If need help, ask!
