What is a database? a database is a centralised and structured set of data stored on a computer system it provides facilities for adding, modifying and deleting the data when required it also provides facilities for transforming queried data into useful information. After defining database queries and similarity search queries, the book organizes the most common and representative index structures according to their characteristics. Solution: treat index kept on disk as a sequential file and construct a sparse index on it. if even outer index is too large to fit in main memory, yet another level of index can be created, and so on. indices at all levels must be updated on insertion or deletion from the file.
