Aquarius.NET® - features

Management

  • Applications, Workspaces and Roles are used by Aquarius.NET management architecture to provide powerful role based security.
  • Appplication is the collection of Workspaces. It is possible to run multiple instances of Aquarius.NET applications on a single computer. Workspaces can be shared across the applications.
  • Workspaces  are primary containers used to store Aquarius.NET objects. Workspace can contain any object type, including other workspaces.
  • Role is a defined set of client permissions. When an client connects to an instance of Aquarius.NET application, it can reference any of the workspace in that instance that the user is authorized to access.
  • Role based security policy works in any type of application (Windows, Web or Web service), because it is implemented at the core level in Aquarius.NET framework.
Analysis

  • Inside Aquarius.NET, heterogeneous data formats are unified using feature sources. This allows processing data in a uniform manner.
  • Data integration object model is composed of Feature Sources, Features, and its Schemas.
  • For data processing and analysis Aguarius.NET provides simple and powerful way. Commands are executed over Aquarius.NET objects and result is stored in a command property. Command is a block with parameters and code, which is executed over Aquarius.NET object (e.g. Layer, Feature Source or MapView).
  • Schema  defines meanig of feature atributes.
  • For attribute and geometry querying Aquarius.NET provides XML based query language . This language is implemented according to OpenGIS specification. A filter expression is a construct used to constraints the property values of an object type for the purpose of identifying a subset of object instances to be operated upon in some manner. This language is implemented in  Aquarius.Data.Filternamespace.
  • Using commands and filters together is useful for advanced analysis. During command execution, filter is applied on each feature and according to the result of expression evaluation the feature is or is not incorporated in command result set.
Geometry
  • Geometry in Aquarius.NET is implemented according to OpenGIS simple feature specification.
