What is the advantage over the ODAC compared to BDE Data Access Components (BDE DAC)?
Very high-speed data access, this is very attractive.
You can adjust the parameters of each execution query to optimize index "resource / production".
You can terminate for a long period of time (unfortunately, this feature is not supported by Oracle's PL-SQL block).
PL-SQL is fully supported. The cursor is obtained by stored procedures or anonymous PL-SQL blocks (using parameters). Get the PL-SQL table by stored procedures or anonymous PL-SQL blocks. Different query support has been built. Built-in runtime debugging system. Simple and convenient use of error handling mechanisms that have been provided. The process of installing an application to other computers is very simple because there is no need to install and configure BDE.
W Use the application software written by ODAC to run on the client, which software support is needed?
To perform an application using ODAC design, you need to install Oracle * SQL-Net2.3 (Oracle 7.3) or Oracle Net8 client on the client.
Do I have the right to release, spread the application of ODAC?
If you purchase ODAC, you have the right to disseminate any compiled, use ODAC design. But you have no right to disseminate any components inherited from ODAC or using ODAC source. You can also view the license.txt file.
Can I use ODAC to create new components?
You can create your own components by inheritance ODAC or using ODAC source code. You have the right to spread and sell (compiled forms), such as components, but not the component yourself. You can view the license.txt file.
In order to compile you to create a package on the standard Query component, you need ODAC's run package odac.dcp.
I have already registered the odac's X.xx version. Do I need to pay for subsequent versions of ODAC?
If you have already registered, if the main version of ODAC is different from the current version, you need to pay again. For example, upgrade from ODAC 1.70 to ODAC 1.85 is free, but upgrade ODAC version 2.00 is charged. The registered price is $ 29, free of charge.
What is the source code of ODAC?
The source code of ODAC contains ODAC in addition to all modules other than the SQL design module, and the SQL designer is available in a DCU file. The SQL designer is only used during the ODAC design process, so it needs its source code.
What is the ODAC does not support BDE DAC?
ODAC does not support other data systems, and cannot create multi-platform applications.
ODAC supports Oracle 7.3 and Oracle 8. Is ODAC to be used in previous Oracle versions?
In order to use ODAC on Oracle's previous version, you need to install Oracle 7.3 and Oracle 8 SQL-Net2.3 on the client. Sorry, if you have already installed other versions * SQL-Net, all settings (including database alias) will be lost. To save these settings, we recommend that you reinstall (installation) The Oracle call interface contained in Oracle 7.3 to serve as an alternative to Oracle * SQL-Net. Such changes will not affect any other installed settings, which is necessary to implement ODAC functionality.
