EMEN 2.2b7 / EMDash 2.2b5 – Object Oriented Database and Electronic Lab Notebook / Client Utilities

EMEN 2.2b7 / EMDash 2.2b5


EMEN (Electron Microscopy Electronic Notebook) is an object oriented database and electronic lab notebook. It is designed to store scientific data in a freeform way without limiting the ability to search/mine the results. Unlike a traditional database, where the contents of each record type (table) must be defined by a database administrator and strictly adhered to, each individual record in EMEN2 can have arbitrary additional parameters outside the record definition, and all such parameters remain fully searchable.
