This is a No-SQL-DataBase project — a simple no-SQL database, developed as a project for the database course at the Computer Science Center.

This application consists of two modules — no-sql-database-client and no-sql-database-server. No-sql-database-client is a client part of the application, no-sql-database-server is a server part. The user interface is a cmmand line. Here are the available commands:

help - print help to show all the available cmmands

To launch this application you need firstly to start a database server. You can do it in this way:
java ru.compscicenter.db.tolmachev.nosqldb.server.httpprotocol.DataBaseHttpServer <database server port>
<database server port> — port on which you want to start database server, for example 2000.

Then, you will be able to launch a command line:
java ru.compscicenter.db.tolmachev.nosqldb.client.commandline.CommandLine <connection host> <connection port>
<connection host> — host on which database server is started. It may be a localhost or another host, where you have started database server
<connection port> — port of the <connection host> on which database server is started
