Abstract: In various embodiments, systems and methods for Multi-Tenant In-Memory Database access to an application program accessing an object-oriented database (OODB) are disclosed. Embodiments may include: connecting, by a processor, the application program to a data repository for a database; generating, by the processor, a first Firm for a first tenant; placing, by the processor, an address of a first object of the first Firm into a knowledge base pointer associated with the first tenant; placing, by the processor, an address of a main database object of the database into a pointer in an object of the first Firm; and accessing, by the processor, the first Firm through the knowledge base pointer and the database through the pointer object of the first Firm.

Abstract: Embodiments of the invention relate to memory management methods and systems for object-oriented databases (OODB). In an embodiment, a database includes a plurality of memory-mapped file segments stored on at least one nonvolatile memory medium and not in main memory. An application program connects to the database with a plurality of writing processes to simultaneously write to an in-memory database, each writing process updating its own disk-based logfile, such that the effective disk writing speed is substantially increased and lock conflicts reduced.

Abstract: A computer system for generating an Instantly Built Information Space (IBIS) for use with an application program is provided. The application program connects to a data repository. The application program connects to at least one Bookkeeping Information Space (BIS). The address of a main database object of the BIS is placed into a knowledge base pointer. The address of a main database object of the database is placed into a pointer in an object of the BIS. The database and the BIS are included in the IBIS. The BIS is accessed by the application program through the knowledge base pointer and the database is accessed by the application program through the pointer in the object of the BIS.
