FOLDERS and FILES

• src/ : erlang source files
• tests/ : text files containing transactions
• bin/ : compiled object codes of erlang source files
• Makefile : makefile to clean and build the erlang code
• README : this file
• doc/datastore.pdf: the pdf instructions file
• launch.sh : script to launch live nodes of transactional manager and datastore
• parser.sh : script to launch the parser function on an input file
• report.pdf : pdf file containing our report

MAKEFILE

• clean : remove all compiled object files from bin/
• all : compile all *.erl files found in src/ to bin/
• service : compile only the erlang files from src/ to bin/ that are needed by the distributed storage service

Execute/Run

• Use <./parser.sh INPUTFILE OUTPUTFILE> to launch a distributed storage system localy, send the commands (INPUTFILE) to it, store the result in a file (OUTPUTFILE) and stop the system
• Use <./launch.sh > to see the explaination and arguments required for launching live nodes
• use only the 'start' functions when starting modules from a erlang shell

Erlang Modules

• app : module that can do update, snapshot_read and gc on a database when a transaction manager is provided
• parser : module that can read and execute transactions from an input file and output the result in a file
• tmanager : module containing the code for the transaction manager
• datastore : module containing the code for the datastore
• performance : module containing the code for testing and finding the performance of our system
