In This Chapter

When a DataBlade API module begins execution, it has no communication with a database server; however, for SQL statements to execute, such communication must exist. To establish this communication, a DataBlade API module must take the following steps:

1. Initialize a connection to the database server and, optionally, a database.
2. Establish the connection and initialize the DataBlade API.

To end the communication, the DataBlade API module must close the connection.

This chapter describes how to initialize, establish, and close connections.
