This directory contains a skeleton for CS61B Project 1. CONTENTS: ReadMe This file. Makefile A makefile (for the 'make' program) that will compile your files and run tests. You must turn in a Makefile, 'make' must compile all your files, and 'make check' must perform all your tests. Currently, this makefile is set up to do just that with our skeleton files. Be sure to keep it up to date. db61b A subdirectory containing skeletons for the db61b package: Main.java The main program---entry point to the db61b system. Utils.java Assorted utility methods. DBException.java A custom exception to report user errors. Table.java Abstraction for one table. Row.java Abstraction for one row of a table. Column.java Abstraction for extracting column values from rows of a table. Literal.java A kind of Column that has a constant value. Condition.java Reprsents a comparison between column values. TableIterator.java A modified iterator for obtaining the rows of a table. CommandInterpreter.java Translates and executes commands. Tokenizer.py Used by CommandInterpreter to read input and break it into meaningful pieces. Makefile A makefile that controls compilation and style checking. testing Subdirectory holding files for integration testing: Makefile A makefile containing instructions for performing tests on your project. students.db, enrolled.db, courses.db Sample database tables from the project handout. test1.in, test2.in Input files for testing. The makefile will respond to 'make check' by running these files through your program, filtering the output through testing/test-filter, and comparing the results with the corresponding .out files. You should add more files to the list in Makefile. REMINDER: These are samples only. They DON'T constitute adequate tests. test1.out, test2.out Output that is supposed to result from test1.in and test2.in, with the first line, all prompts, and all blank lines removed (which is what test-filter does). testing.py A Python 3 module containing a framework for integration testing. Used by tester.py. tester.py A Python 3 program that tests your project. It runs your program with each .in file, comparing the output with the corresponding .out file and producing a report of the result.
