Example details from the ‘Maintainability’ section of undisclosed client code audits:

Audit excerpt

The Undisclosed Client’s web application is built around a series of old technologies. The application is aesthetically pleasing, and files are fairly well organized. Unfortunately there are many fundamental issues that stem from a lack of solid architecture, database design, and security.

The result of these flaws is a product that is not secure, cannot guarantee correctness, compromises data integrity, and ultimately one that will be difficult to maintain and scale moving forward through the software development lifecycle.

Audit excerpt

The code makes very little use of view helpers, and has only one partial defined. Partials are used to render code that is used on multiple pages, implying that code is being recreated on a number of pages unnecessarily. In addition, there are instances of large volumes of HTML content is being echoed as a string from PHP, rather than just writing out the HTML. Specifically the $addexceptionWidgetHtml uses a large HTML string, which might be better implemented in a helper or partial.

If this is unavoidable, the use of a HEREDOC or NOWDOC (PHP implementations of pre-formatted verbiage, useful for showing code) might bring some clarity.

Audit excerpt

Our recommendation for business logic is to create a layer in your .NET code to handle most business logic. While it is inevitable that some business logic will exist outside that layer (for example, data-intensive logic will sometimes occur in a stored procedure, or validation in the UI), having a business logic layer is the most flexible option and also allows for repeatable automated testing.

While we don’t recommend putting business logic in stored procedures, logic to manipulate data is appropriate and expected in stored procedures, including complex manipulation.
