Problem: Please answer a question about the following article about Database:
In this paper, he described a new system for storing and working with large databases. Instead of records being stored in some sort of linked list of free-form records as in CODASYL, Codd's idea was to use a "table" of fixed-length records, with each table used for a different type of entity. A linked-list system would be very inefficient when storing "sparse" databases where some of the data for any one record could be left empty. The relational model solved this by splitting the data into a series of normalized tables (or relations), with optional elements being moved out of the main table to where they would take up room only if needed. Data may be freely inserted, deleted and edited in these tables, with the DBMS doing whatever maintenance needed to present a table view to the application/user.
What system assists a user in seeing a table?
A: DBMS
Problem: Please answer a question about the following article about Hunter-gatherer:
At the 1966 "Man the Hunter" conference, anthropologists Richard Borshay Lee and Irven DeVore suggested that egalitarianism was one of several central characteristics of nomadic hunting and gathering societies because mobility requires minimization of material possessions throughout a population. Therefore, no surplus of resources can be accumulated by any single member. Other characteristics Lee and DeVore proposed were flux in territorial boundaries as well as in demographic composition.
What can decreased material possessions produce in a hunter-gatherer society?
A: egalitarianism
