Now we will discuss transaction processing as it relates to the c-treeACE SQL ODBC Interface.
Transaction processing provides a safe method by which multiple database operations spread across separate tables/files are guaranteed to be atomic. By atomic, we mean that, within a transaction, either all of the operations succeed or none of the operations succeed. This "either all or none" atomicity ensures that the integrity of the data in related tables/files is secure.
Like all other examples in the c-tree tutorial series, this tutorial simplifies the creation and use of a database into four simple steps: Initialize(), Define(), Manage(), and You’re Done()!
Tutorial #4: Transaction Processing
Here we demonstrate transaction control.
Note our simple mainline:
* The main() function implements the concept of "init, define, manage
* and you're done..."
int main(int argc, char* argv)
printf("\nPress <ENTER> key to exit . . .\n");
We suggest opening the source code with your own editor.
Continue now to review these four steps.
