pgModeler
pgModeler
Create and edit database models easily with a simple and intuitive interface. The forms indicate which fields must be filled to provide the correct generation of SQL code. Get, modify, and redistribute the source code without any charge. This project has a public repository that allows forks and full access to the source code. Developers can create their own versions from the existing code. Built on top of the Qt framework, pgModeler can be compiled on Windows, Linux and macOS. The build scripts are easily configurable to resolve specific dependencies on each operating system. Design once and export to multiple versions. With its dynamic code generation, pgModeler can export the designed models to different versions of PostgreSQL (currently from 9.x to 13.x). Missing some functionality? Use the plug-in development interface and create your own extension for pgModeler without change a single line of the core code.Starting Price: $49.90 one-time payment -

System Architect
UNICOM Global
UNICOM System Architect is a market-leading enterprise architecture tool that enables you to build and automatically generate data-driven views of your organization's enterprise architecture -- its strategy, business architecture, operational architecture, data, application landscape, supporting systems, technologies, and infrastructure. Together, these views form a mosaic that delivers the insight and analytics necessary to describe current and future states of the enterprise along with interdependencies, risks, life cycles, and standards. And from that – you can “ask the architecture questions” – and know how good the answers are based on viewing the health of the architecture itself – what it’s missing, how old it is, where its sources of record lie, and who made changes to the architecture and when.
