Availability also needs to be defined. Does having a read-only database available for queries fit the requirement? If writes are required, could all changes be captured on the secondary database for inclusion in the primary database once it is available? Metadata changes—–whether a switch or key field text—are frequently used for application settings. Metadata changes can also manage other configuration settings. For example, one entry could simply be the code version to be executed. With that, somewhere in the code a read of the metadata to determine how to execute based on the defined code version.
There is a movement away from waterfall project management—serialized code progression starting with development and then proceeding to testing, integration, quality assurance, and production. New opportunities to create applications in weeks or even days has led to products being produced and then held for release until the company can be officially formed and readied for business operations. That reality did not seem possible a short 10 years ago. Powerful tools have enabled businesses to move from “scrape together a little money, spend most of the money forming the company, start coding, go hungry, sleep in the car, beg for more money from family and friends, visit Mom and Dad to get laundry done and consume real food, and release version 1 in desperation, hoping to generate enough revenue to fix numerous bugs to be released as version 2” to an early-capture revenue model in which the application is built and readied to release and generate revenue, possibly even while the paperwork to form the company is underway.
This process requires a formal change request that tracks the problem, the cause, the corrective action, and the name of the person who made the change. The change request can then be managed from the back log, ensuring inclusion in the code trunk. Third is the best-suited scenario for this situation and for general releases: the build process needs to compare the source (new version), the target (environment to be deployed to), and the baseline code version (last release). For example, if deploying code version 5, it is necessary to ensure that the deployed-to environment does not lose code that may have been put into place to correct a problem.
