Using Easycom For Delphi, Delphi applications can have complete real time access to AS/400 resources, without any data replication.
Easycom For Delphi database-related features include:
Files can be read from, written to and updated whether they are physical, logical or 36 format. In order to provide optimum performance, Easycom For Delphi uses existing access paths and uses native mode access only.
• Delphi programs use logical files as indexes.
• No code is generated on the AS/400.
• Database integrity constraints are fully respected.
• Access to query files.
• Setup and query of databases (OPNQRYF, OVRDBF, etc.).
• Simultaneous access to multiple AS/400.
• File sharing and record level locking.
• Access to Commitment Control.
• Record Level access to data.
Easycom For Delphi resource-related features include:
All AS/400 resources can be accessed from within Delphi. Programs can be called from within Delphi, parameters can be passed, and the results can retrieve back in the PC environment.
• Submit a command and execute on AS/400.
• Invoke AS/400 programs and retrieve returned parameters.
• Access to data areas and data queues.
• Access to AS/400 jobs.
• Access to communication APIs.
AS/400 Communication Protocol
TCP/IP
TCP/IP is the standard in communication for AS/400. It provides better performances and is integrated in Windows, so no additional product is required.
Native Mode
All database access is done in native mode for optimum access speed and to minimize resource requirements. Native mode access yields performance, which cannot be attained using DDM (Distributed Database Management), or resource intensive SQL.
Batch Reads
By using batch reads, entire sets of data can be retrieved in a single pass.
