This repo is the base codes of the ClassProject of 2023Spring CSCI485.
You need to copy and paste the code of Part 1, 2 and 3 to this project.
Your codes need to be put under src/CSCI485ClassProject/
and its subdirectories.
Verify correctness by executing the unit test of Part1/Part2/Part3 successfully.

: package storing some defined representations of models in the database.test
: package for unit tests
Under src/CSCI485ClassProject
, there are 2 classes to finish:
RelationalAlgebraOperatorsImpl
: implementation of an interface classRelationalAlgebraOperators
Iterator
:Iterator
is an abstract class of the concept of Iterator. You need to implement derivative classes ofIterator
to implement required features.
If you are developing in macOS/Linux
environment(recommended), we provide Makefile
for you to run tests quickly.
To run tests of partX, use command
make partXTest
As you may have different project structures, Makefile may not work in your implementation. In this case, you can change the sources
variable in Makefile by adding the name of the java files you created to it.
Note that the order of the file should align with the class dependency relationship, i.e. class A
imports B
, then B.java
should be in front of A.java
in sources
.
