SlashDB automatically generates a REST API from relational databases for reading and writing in convenient formats like XML, JSON and CSV. Additionally, using HTML it allows for simply browsing through data so users can discover available databases, tables, queries and API endpoints. SlashDB is capable of providing a central access point to multiple databases, effectively forming an all-encompassing resource-oriented architecture (ROA), serving as an API gateway to the data for users that need access. SlashDB provides a web service shell for each of your database(s) by translating relational database structures into a logical library of uniform resource locators (URL). Conforming to REST methodology, every piece of data has its own unique identifying URL regardless of whether it is a simple scalar value or a nested structure of related records.

One area hasn’t benefited from the DevOps movement as much: The database change process. It’s time to bring CI/CD to the database. Application release technology has come a long way in the past several years. It used to take weeks or even months to release new software. Now that organizations have adopted new workflows and processes, the time it takes to complete a release has been reduced to days and even hours. Database schema migrations are an essential task for every software project. There are several different reasons why updates to the database are required. New features require new attributes in existing tables or entirely new tables. Bug fixes may lead to changes in names or data types in the database. Performance issues that require additional indexes in the database. Even in organizations that have adopted DevOps, manual rework is the norm when it comes to database schema and stored procedure changes.
