Jun 15/96 - ODBTalk version 3 for Visual Smalltalk and VisualWorks - Win32
LPC Consulting Services announces a major enhancement release for ODBTalk, the leading Smalltalk database framework for ODBC. This product provides the Smalltalk developer with full ODBC SDK 2.1, level 2 support to allow access of more than 50 databases with the same application code across operating systems(Win32s, Windows-NT, Windows-95) and Smalltalk environments. It includes a framework for mapping Smalltalk classes to relational tables and vice-versa based on types and brokers, ideal for complex client-server applications.
Version 3 Enhancements
- Automatic SQL DDL generation from OO Model
Define an OO model entirely in the Mapping workbench. Then generate the appropriate schema to create the tables, primary keys, etc. ... for your datasource.
- Automatic OO Model generation from SQL schema
Generate a model from an existing relational schema. You select the tables, the keys, and the relationships from your datasources and generate an OO model .
- Smart caching of Model instances
Cache mapped objects. You can also use the various caching policies supplied (e.g. always refresh from datasource ...) or provide your own (through a Smalltalk block). When caching is used, only one instance of a mapped object can exist in your image, preserving identity.
- ODBC API Smalltalk trace
Generate a trace of ODBC calls. This trace provides the message selector, arguments and results. It can be turned on and off as required.
- Improved performance in instantiation of Model instances
The mapping framework has been highly optimized to minimize the overhead of mapping tables to Smalltalk objects. As well the use of the cache will reduce database (and network) usage and delays when performing key retrievals.
- Ability to fully document models
Every element of a model can have a definition attached to it. This includes models, types, relationships and attributes.
- Ability to export and import models in images
Models defined with the framework can be filed out and filed in, therefore allowing a team to share models as well as restoring models in a brand new image.
System Requirements
ODBTalk version 3 requires Visual Smalltalk or VisualWorks and ODBC drivers for the databases you wish to access. The cost of a new license is $399 US; current ODBTalk users can obtain this update for $129 US.
