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.

Data Controller is designed to provide business users with a tool which can be included in their overall armoury for regulatory reporting. Having worked in data-intensive SAS environments for many years, the founders of Data Controller experienced first hand the inefficient practices that reporting teams had to endure when changes needed to be made to the data and source system access wasn’t possible. It was clear to see that users needed the ability to self-serve their data updates. That data owners should have the chance to review and approve those updates. And that all changes to data should be safe and secure, as well as tracked and visible for audit reasons. The Data Controller is useful for any Enterprise that needs to perform manual data uploads into their preferred database, in real-time, with full validation, approval, security, and control.

PostgreSQL GUI tool for macOS. PSequel provides a clean and simple interface for you to perform common PostgreSQL tasks quickly. pgAdmin is great for its feature-richness. However, its UI is clumsy and complicated. There is a list of PostgreSQL GUI Tools. However, they are either web-based, Java-based or don't support the features some want. In the good old MySQL world, the best client is Sequel Pro, but its support for PostgreSQL doesn't seem to be happening. So, we decided to make one. PSequel is written from scratch in Swift 2, although PSequel's UI is highly inspired by Sequel Pro. PSequel is being developed in our spare time. By supporting macOS 10.10+ only, the codebase can be kept simpler and save time by not testing it in older versions of macOS. And, less code, less bugs. PSequel is still in its early stage.
