Changes in this edition:



	



	1) Included file called prof_data_rdr. This is my executable



	version of the interactive program data_rdr. Use it to read 



	the data in a binary data file, for example, databases/students.sto.



	



	The command should be: ./prof_data_rdr 



	and the program will ask for the name of the target relation.








	



	2) Added the prototype of the functions to evaluate relational and 



	logical operators into the predicate.h file.
