9.3.2 Dynamic Allocation of Documents

There is also a trade-off involving the location of documents. The parameters of this

trade-off are storage requirements, access time, update time and difficulty, document

integrity, document security, and document reliability. For example, one copy of each

document implies 1) guaranteed integrity, 2) slow acess, and 3) minimum storage. Al-

lowing multiple copies of each document implies 1) increased storage, 2) faster access,

3) increased reliability, 4) slower updates, and 5) possible loss of integrity.

The MINDS system dynamically allocates documents, involving the placement, copy-

ing, and migration o ...
