PmDB - licence for access to external databases
Basic information:
In the PROMOTIC system there are inbuilt the
ODBC,
DAO,
SQL default interfaces for the access to external
databases.
By means of the
PmaAdo object (or
PmaDatabase) the user has access to databases of several types, for example:
dBase,
Excel,
Microsoft Access,
PARADOX,
FoxPro,
MS SQL Server,
MySQL,
Oracle, etc.
These objects allow to perform both simple and complex
database operations of the following types: read/write records, select, sorting, etc.
Trade terms:
The usage of the
PmaAdo and
PmaDatabase objects requires purchase of the
"PmDB" licence. When developing the application in the freeware mode
PmFree, or with
development environment and while testing it in runtime, this component is always functional.
Note: The
PmDB licence is used only for the
PmaAdo and
PmaDatabase objects functionality. For writing and reading to/from databases or files by another means, this licence is not needed (e.g. saving the data in the
PmaTrendGroup object,
Pm disk/files methods .. - see
Data sharing by files).
