Integrating low-code platforms with existing systems has become an essential strategy for businesses seeking to accelerate digital transformation without overhauling their entire IT infrastructure. Low-code solutions empower organizations to rapidly develop and deploy applications, but to deliver real value, these new tools must communicate effectively with legacy systems, core databases, and enterprise applications. This seamless collaboration not only preserves past technology investments but also unlocks new efficiencies and possibilities. By understanding the challenges, approaches, and opportunities associated with low-code system integration, businesses can realize the benefits of agility, scalability, and innovation without sacrificing security or stability.
