Yearly Funding

ARIA Needed Repairs

The Issues

• No funding…– Elevates the importance

of service reliability

• Challenges– Code documentation– No system to enforce the use of current

programming practices– User interface

In-code Documentation

• Definition:Comments (text) placed within the code, which are ignored by the program (information only, not running operations).

In-code documentation is used to explain the purpose and functionality behind the code.

• Problem:– Without documentation, developers spend too much time

understanding A.R.I.A instead of maintaining it.

• Solution:– Configured software (IDEA) to produce default documentation.

• Promotes code readability.

In-code documentation

ActualCode

Metadata

• Definition: Generated data about data.• Important for the users.• Problems:

– Metadata was entered by hand. – Slow process.

• Solution:– Created scripts that automatically produce metadata

for all imagery on the servers.

Code Abstraction

• Definition: A mechanism used to reduce and factor out implementation details so that one can focus on a few

concepts at a time. • Example: Communication between scripts and database• Solution:

– Mechanism: Hibernate software– Implementation details: SQL queries.

• Increases productivity.

User Interface

Significance of ARIA

• Unique and irreplaceable service
