Lattice.DataMapper

 Home Page Home Page
Categories:
Author: Lattice Business Software International
Latest version: 3.0
Description: Object persistence library for relational databases.
Lattice.DataMapper bridges the gap between objects and data source and allows the developer to work at the object level with little knowledge of the data source. In addition, Lattice.DataMapper shields your business logic from data source schema changes and data source provider changes.
Lattice.DataMapper maps .NET objects to and from an underlying relational database using external XML configuration and mapping files. The data access is externalized in XML and can include both SQL queries and stored procedure calls. An API is provided to then dynamically store and retrieve .NET objects using the mapping definitions.

Features include:
- Support for different data providers and multiple data sources
- Supports object pre-fetch (one-to-one, one-to-many, many-to-many relationships)
- Queries are batched and run as one transaction
- Batch job can be run asynchronously at scheduled time as separate thread
- Cache can be set up per query (supports cache database dependency)
- Supports .NET 2.0 generics and nullable value types
- Logging and error handling using Log4net
- Support distributed transactions without deriving from ServiceComponent
- XML file based configuration file to define available data providers and data sources
- XML based mapping files to define O/R mapping
- XSLT template based tool to auto-generate stored procedures, business entities and mapping files.

It includes tools to create the database schema from the object model and provides schema information at runtime allowing it to dynamically generate all SQL required for object persistence management. At the same time, much like ADO.NET DataSets, it is independent of the actual backing store and works equally well with objects transmitted in an XML representation.

NHibernate

 Home Page Home Page
Categories:
Latest version: 2.0.0 Alpha 1
Description: Object persistence library for relational databases.
NHibernate is a port of Hibernate Core for Java to the .NET Framework. It handles persisting plain .NET objects to and from an underlying relational database. Given an XML description of your entities and relationships, NHibernate automatically generates SQL for loading and storing the objects. Optionally, you can describe your mapping metadata with attributes in your source code.

NHibernate supports transparent persistence, your object classes don't have to follow a restrictive programming model. Persistent classes do not need to implement any interface or inherit from a special base class. This makes it possible to design the business logic using plain .NET (CLR) objects and object-oriented idiom.

Features include:
- Supports natural OO idiom; inheritance, polymorphism, composition and the .NET collections framework
- Support for fine-grained object models: a variety of mappings for collections and dependent objects
- No build-time bytecode enhancement: there's no extra code generation or bytecode processing steps in your build procedure
- The query options: NHibernate addresses both sides of the problem; not only how to get objects into the database, but also how to get them out again
- Support for "conversations": NHibernate supports long-lived persistence contexts, detach/reattach of objects, and takes care of optimistic locking automatically

OR.NET

Categories:
Author: Adam Rackis
Latest version: 5.0
Description: Open source object-relational mapper and code generator.
OR.NET generates a data access layer in stand-alone C# 2.0 after scanning your database’s meta-data.

Features include:
- Creates all relationships based on both simple foreign keys, and many-to-many mapping tables. All identity columns will be found, and treated appropriately for inserts, and all nullable fields will be created as nullable properties in code.
- Transparently manages all foreign key relationships, and many-to-many relationships for you.
- In addition to automatic class structure generation, you can also manually create and modify classes by specifying which columns represents the key, which columns to create properties out of, and which other objects the new class links to, either through a foreign key, or a many-to-many mapping table – all through a GUI.
- The classes generated are database independent, with all data-access happening through generated assembler classes.
- All SQL commands are fully parameterized, and therefore resistant to injection attacks, and also slightly better performing due to SQL Server’s caching of execution plans.

Diamond Binding provides an add-in for Visual Studio 2005 that allows selection of tables from your SQL Server 2000+ database to be available in code following the Active Record pattern. It keeps the definitions of mapped objects synchronised in partial classes (similar to the form designer) with little generated code.
The API provided by the Diamond Binding runtime supports CRUD operations on objects, relationships, complex and simple queries, lazy loading, cascades and more. Diamond Binding supports generics, so all interactions with your data layer occur in a type-safe fashion. Schema changes are then found at compile time, rather than deployment.

Nolics.net provides for the automatic persistence of the classes. The members of the class are filled with data by automatically generated SQL statements and likewise, the updated objects are automatically saved into the database.

Features include:
- Extracts the DDL file from the application object model.
- SQL Query API: can be used to build queries independently of the native SQL dialect the actual database is using.
- Virtual Links mapping technique: concept to build views within the business entities. Values of related entities can be joined directly into the object as read-only properties.
- Versioning: adresses database versioning via version attributes on classes and properties. This feature makes it possible to work with different database versions at the same time using the same entity model. The version used at runtime can be selected by the concrete instance of the ObjectMapper .NET.
- Paging: intended for server-side paging, a feature for browsing large collections of data.
- Object localization: a method is propvided to localize value objects for different languages. This is done implicitely during database queries, no additional queries are required.
- The requirements of the framework on the entity model are an interface supported by entity classes and meta information provided as attributes on classes and properties.
- Possible use of typed or self defined collections
- Optimistic concurrency
- Open for custom factory frameworks: instead of hardwiring the creation of objects, it is separated and customizable.
