EXPRESSbase is an enterprise-grade ‘High Productivity’ rapid application development (RAD) platform or hpaPaaS on the cloud specifically targeting Small & Midsized Businesses (SMB or SME). SMBs grow fast compared to large enterprises, which triggers frequent changes in processes and workflows demanding adaptable and ever-evolving business software. Traditional development & delivery models are high ‘time–effort–money’ exercises. ‘High Productivity’ application platform as a service (hpaPaaS) or aPaaS is the answer to the ‘time–effort–money’ crunch. According to Gartner by 2020, at least 50% of all new business applications will be created with high productivity toolsets. EXPRESSbase takes the hpaPaaS to the next level by providing tools to manage engineering life cycle, chatbot builder, schedulers, IoT connectors, a full-fledged Document Management system, built-in audit trail, etc., in addition to the industry standard features like drag-n-drop form builder, report builder, data-visualizations and workflows. The platform also includes Email/SMS capabilities, integrations like Slack, Assignments, Approvals with configurable Approval chain and Relationships EXPRESSbase greatly reduces complexity in engineering by providing a single environment (tenant instance) for dev, test, UAT, and prod. EXPRESSbase is envisioned and designed as a truly multi-tenant, multi-database, multi-lingual, multi-location, and scalable platform. A client can hook their database server (private/public cloud or on-premise) to the ExpressBase cloud infrastructure secured by SSL/TLS. They can then browse the application template repository and pick a suitable app template and deploy it. App developers using the platform need not learn any new proprietary language. They can use SQL, JavaScript to develop apps on our platform.
