Mimer SQL's Module SQL (MSQL) redefines database integration by isolating SQL statements into separate modules, enabling seamless calls from host programs in C, COBOL, Fortran, or Pascal without embedded code clutter. This technique streamlines maintenance, enhances portability, and addresses the complexities of data type mapping across diverse programming environments. For developers juggling legacy systems and modern databases, MSQL offers a pragmatic path to cleaner, more resilient data access layers.
