The Zope Object Database (ZODB) is an object-oriented database for transparently and persistently storing Python objects. It is included as part of the Zope web application server, but can also be used independently of Zope. Features of the ZODB include: transactions, history/undo, transparently pluggable storage, built-in caching, multiversion concurrency control (MVCC), and scalability across a network (using ZEO). ==History== * Created by Jim Fulton of Zope Corporation in the late 90s. * Started as simple Persistent Object System (POS) during Principia development (which later became Zope) * ZODB 3 was renamed when a significant architecture change was landed. * ZODB 4 was a short lived project to re-implement the entire ZODB 3 package using 100% Python. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Zope Object Database」の詳細全文を読む スポンサード リンク
