ADO.Net VCL for Delphi v4.0.0.0 Released

Posted By CrystalNet on December 28th, 2017

The CrystalNet Technologies LTD company has released a new version of the ADO.Net VCL for Delphi v4.0.0.0.


ADO.Net VCL for Delphi is the fastest and most reliable database connectivity solutions for any database using ADO.Net technology in Delphi. It provides data access to data sources such as SQL Server, Oracle and to data sources exposed through OLE DB and ODBC using ADO.Net data provider framework. ADO.Net VCL for Delphi is an enterprise solution with highest performance and unlimited possibilities. Data-sharing consumer applications can use ADO.NET VCL for Delphi to connect to these data sources and retrieve, handle, and update the data that they contain.

With its powerful common architecture base on ADO.Net technology, ADO.Net VCL for Delphi enables high-speed direct data access from Delphi to SQL Server, Oracle and other data sources exposed through OLE DB and ODBC.

This article summarises basic requirement and key new features and improvements in this version. This VCL is a new design and implementation and the design architecture is different from the previous version.

Pre-requisite
Supported Target Platforms
  • Windows, 32-bit and 64-bit
General usability
  • Direct access to server data without using client library. Does not require installation of other data provider layers (such as BDE)
  • Interface compatible with standard data access methods, such as ADO
  • Bulk copying of data from a data source to Sql server database using TSqlClientBulkCopy component
  • Supports the posting of deferred updates, so called Cached Updates.
  • Provides methods to sort the records. The dataset sorting allows you to get the required records order without requiring a database
  • Provides methods to filter the records. The dataset filtering allows you to get record subsets based on a condition
  • Provides flexible support for master-detail relationships between datasets
  • Support prefetching rows - specifies the number of rows that are to be fetched per server round trip This is controlled by FetchOptions.RowsetSize property
  • Unicode support
  • Easy to deploy
Network and connectivity
  • Disconnected mode with automatic connection control for working with data offline
  • Transmission is via XML format, therefore can pass through firewalls
Compatibility
  • Full support of the latest server versions
  • Compatible with Code Gear RAD Studio 2009, Embarcadero RAD Studio 2010, XE, XE2, XE3, XE4, XE5, XE6, XE7, XE8, Seattle, Berlin, Tokyo
  • Support for all standard and third-party visual data-aware controls
Performance
  • High performance access to the data source
  • Fast controlled fetch of large data blocks
  • Advanced connection pooling
  • High performance of applying cached updates with batches
  • Fast locate in a sorted DataSet
  • High performance batch processing
  • Intelligent fetch block size control
  • Rowset fetching support using TDbRecordSet Class which mimics the behaviour of ADO RecordSet Object using ADO.Net technology
  • ADO.NET VCL components uses XML to store and transfer data among applications, which provide fast access of data for desktop and distributed applications
Local data storage operations
  • Database-independent data storage with TClrMemtable and TClrDataTable components
  • CachedUpdates operation mode which is controlled UpdateMode property
  • Local sorting and filtering, including by calculated and lookup fields
  • Local master/detail relationship
Data access and data management automation
  • Automatic data updating with Query, Table, and StoredProc components
  • Fast-forward data retrieval with DataReader component
  • Automatic record refreshing and locking
  • Automatic query preparing
Data exchange
  • Transferring data from all types of TCustomClrDataSet descendants, Xml etc to a Sql Server database using TSqlClientBulkCopy component
  • Data export and import to/from XML
Product clarity
  • Documentation will be available very soon
  • A large amount of helpful demo projects
Licensing and support
