The MUDzilla Simulation System

MUDzilla Database Model

"The problem with owning everything in the Universe is finding a place to put it." -- George Carlin

As you analyze your ideas and organize your thoughts, you will use MUDzilla to store your work. MUDzilla is based on relational database technology, where a collection of database tables are assigned relationships between one another based on data they share in common. Each table is divded into records (or rows), and each record is divided into fields (or columns). Within each field lies a value, which represents a single piece of information regarding the Multiverse. A snapshot of a MUDzilla database represents a moment in time, where the sum total of all values in all records in all tables indicates the current state of the simulation.

MUDzilla uses the Paradox 7 format, a flat-file database where the relationships between tables within the database are maintained as part of MUDzilla software applications. The link between our software and the underlying database is managed by the Borland Database Engine, which provides a Structured Query Language (SQL) interface. SQL is a powerful data manipulation language that extends the scalability of MUDzilla to other database platforms, such as Oracle and SQL Server. In time, the Paradox format will cease to meet the needs of a large simulation. SQL ensures that when the time comes to scale up to a database server, the overall logic of MUDzilla will be preserved.

A MUDzilla database is the static part of a simulation, a vast store of knowledge which, taken together, represents the past. Not until the simulation is started does the database transition into a reflection of the present. To make this leap, the simulation needs to represent information known only while the simulation is active, the simulation's short-term memory. This is the exact purpose and function of objects, which have both persistent parts, information which is stored in the database, and memory parts, knowledge which only exists during the lifetime of the object. MUDzilla enforces the Nothing Unreal Exists axiom by ensuring that all data is manipulated within the context of the object model.
