A computer system and a method for analysis and visualization of
signalling and metabolic pathways, comprising inter-related databases
including external database, a pathway database for storing curated
signalling interaction between the biological entities and biological
entity data, said databases including a pathart database, a curator
member to generate curated signalling interaction between the biological
entities obtained from external sources, said pathway database comprising
a hierarchical arrangement of signalling interactions among the
biological entities and biological entity data, said pathart database to
store mapped addresses for hierarchically arranged signalling
interactions among the biological entities and biological entity data, a
processing system including a server module to fetch and/or generate
desired pathways dynamically from the stored signalling interactions and
biological entities, said processing system to obtain information on the
selected biological entities or their interactions from said dynamic
pathways, a user interface for creating, querying, and viewing the
dynamic pathways, and micro array data captured by a user.
