Elements and Performance Criteria

1. Install application programming interfaces (APIs) suitable to the game’s data source provider
   • Research the appropriate application programming interfaces (APIs)
   • Identify the specific APIs suitable for the game architecture and the data source provider
   • Install the nominated APIs on game development computers
2. Define and use a connection to the data source
   • Define the game data source connection parameters
   • Store the connection parameters in an external text-based configuration file
   • Open and close the connection to the game data source
3. Configure and use the connection pooling
   • Configure connection pooling in the database management system
   • Define the connection pool parameters for minimum connections, maximum connections, and idle connections
   • Minimise the use of database resources through the use of connection pooling
   • Test and verify the use of connection pooling
4. Pass embedded structured query language (SQL) to the database
   • Define the database connection property
   • Compose a structured query language (SQL) statement or command to be passed to the database
   • Test, debug and execute the SQL statement
5. Execute a stored procedure on a database
   • Call a stored procedure on the database, using a command callable statement
   • Define and pass the parameters to the stored procedure
   • Test, debug and execute the database stored procedure
6. Modify database data
   • Retrieve multi-row multi-column result sets from the database into the game application domain
   • Insert new records into the database
   • Update existing database records
   • Delete existing database records
7. Integrate data from the database with the game application domain
   • Integrate data from a forward-only and read-only cursor into the game application domain
   • Incorporate the data from an updateable cursor into the game application domain
8. Test and debug database integration code
   • Test the database integration code
   • Document the test results
   • Determine the errors and exceptions, and document the solutions
   • Debug all errors and exceptions
   • Assess all data modifications in the database, and document any errors
   • Correct all causes to data modification errors
9. Install application programming interfaces (APIs) suitable to the game’s data source provider
   • Research the appropriate application programming interfaces (APIs)
   • Identify the specific APIs suitable for the game architecture and the data source provider
   • Install the nominated APIs on game development computers

Performance Evidence

Evidence of the ability to:

determine and install application programming interfaces (API) for games development

define and add database functionality to an online game

integrate, test and modify the database data provided by game-play input and document all errors and solutions.

Note: If a specific volume or frequency is not stated, then evidence must be provided at least once.

Knowledge Evidence

To complete the unit requirements safely and effectively, the individual must:

provide a detailed explanation of relational database theory, including how:

to create and test stored procedures

to create ‘embedded’ structured query language (SQL) and to assign parameters in the code for filtering

tables are related, and how relationships between tables are implemented

SQL is used to retrieve data from multiple tables

inserts to tables in parent/child relationships can be implemented using artificial (auto-generated) primary key values

to implement cascading updates and deletes

summarise the principles of game development

explain the principles of integrated development environments, including:

data access APIs and associated classes, required for the integration of a database with an online game

online help and documentation required for research and debugging code

user authentication and authorisation management

outline the methodologies and techniques required for effective and well-factored object-oriented program (OOP) code, including:

class implementation

control of logic flow

use of collections and lists

use of OOP concepts, such as inheritance, encapsulation and overloading

describe the implications of web development on games integration.
