Migrating data from InterSystems Cache to SQL Azure

This guide walks you through migrating data from InterSystems Cache to SQL Azure in a few simple steps using ESF Database Migration Toolkit. Simplify complex migration tasks and save valuable time with our streamlined approach.

InterSystems Cache vs. SQL Azure:

  • InterSystems Cache is a high-performance object database management system and rapid application development environment designed for transactional applications. It offers a powerful database engine coupled with a robust set of development tools, making it suitable for building scalable, data-intensive applications in healthcare, finance, and other industries. Cache excels in handling complex data structures and large volumes of data while providing real-time analytics and seamless integration capabilities. Its advanced features include support for SQL, object-oriented programming, web services, and interoperability with various programming languages, making it a versatile solution for modern application development needs.
  • Microsoft SQL Azure, also known as Azure SQL Database, is a fully managed relational database service provided by Microsoft. It offers scalable and high-performance SQL database capabilities in the cloud, with built-in high availability, automated backups, and robust security features. Designed to handle both small and large-scale applications, Azure SQL Database simplifies database management tasks, allowing developers to focus on building applications without worrying about underlying infrastructure. It supports various deployment options, including single databases, elastic pools, and managed instances, catering to diverse business needs.
