Abstract: A novel database query and writing engine for rapidly storing, retrieving and modifying large amounts of data on mobile devices is disclosed. The innovative database engine software comprises the creation of a set of files for each table in a database, wherein CRUD (create-retrieve-update-delete) operations are streamlined for mobile or other devices by organizing memory for efficient read and write operations. The set of associated files segregate fixed length and variable length data types for faster seek, read and write operations, and keep track of changes to values and database table schema changes in terms of deletions and insertions of rows and columns. The innovative database engine manages complexities associated with storage and retrieval of large amounts of data, which comprise CRUD operations. In addition, the database engine introduces a dual buffer system to more rapidly process blocks of database memory.
