ECO II major features areas

• The major areas
• ECO.ASP.NET
• ECO Enhanced O/R Mapper
• General improvements
• Scalability, Webability, Adaptability, Ease of
  use-ability

10
ECO II - ASP.NET II

• Native .NET
• Built on native ASP.NET
• Binding to ECO ExpressionHandles
• Templates for ECO.ASP.NET app, ECO WebServices
• DBWebControl support
• Use DbWebControls with ECO based ASP.NET
  applications
• EcoDatasource exposing EcoSpace

11
ECO II - ECO Space in ASP.NET

• EcoSpaceProvider
• Manages Sessions and SessionState policies
• Provides a pool a EcoSpaces
• Synchronization managed through PersistenceMapper

12
ECO II - ECO Space in ASP.NET

• EcoSpaceProvider. SessionState
• Never Never cache, return to pool.
• Always Keep it for the duration of the session.
  When the session ends, return it to the pool.
• IfDirty Keep if dirty. This mode allows
  applications keeping state over multiple requests.

13
ECO II - ECO Space in ASP.NET

• Pooling strategies
• Application Settings in Webconfig.xml
• Setting MaxPool to gt0 will enable pooling.
• ltadd key "Borland.Eco.Web.MaxPool" value
  "0"/gt
• EcoSpaces will be discarded based on MaxAge (s)
• ltadd key "Borland.Eco.Web.MaxAge" value
  "60"/gt

14
ECO II - Synchronization

• Scalability through syncronization of multiple
  shared EcoSpaces
• PersistenceMapperProvider
• Connects the EcoSpace(s) to the PersistenceMapper
• Remotable and thread safe
• PersistenceMapperSharer
• Multiple EcoSpaces in a single process
• PersistenceMapperClient
• Multiple EcoSpaces in separate processes

17
ECO II WebServices

• Very similar to using ASP.net
• Sessionstate always never
• ECO WebServices template used to create projects

18
ECO II Concurrency Handling

• Optimistic locking only
• Conflict resolution in multiple EcoSpace
  applications
• PersistenceMapper Service
• Apply, Discard, Ignore each individual Change or
  ApplyAllChanges()

19
ECO II O/R mapper

• Basic OR mapper
• Model to Db Schema, forward generation
• Evolve db based on model changes
• Enhanced OR mapper
• Generalized OR mapping
• User controlled Ids
• Any column, composite, Autoinc, GUIDs
• Map onto existing db using schemas files (XML)

20
ECO II O/R mapper

• XML mapping Schemas
• Build manually
• Generate mapping schema from model
• Reverse/wrap Database (ObjectMapper plugin)
• Evolve existing db from model changes
• Automatic for non-complex changes to model

21
ECO II - General Usability

• General design time improvements
• Framework re-factored, pluggable
• Increased amount of code-free functionality
• Easier custom use of low level functionality
• Extendable, pluggable IDE ( EcoSpace designer )
• additions by community / partners (ObjectMapper)

22
ECO II - General Usability

• Setting up WinForms apps, using actions, even
  simpler
• Autoforms improved drag drop, single link
  navigation
• Documentation improved
• Increased number of examples
• Increased amount of source
• Together Designer improved
