Essential Management provides a project management system for organizing and writing technical documents.

Essential Management is a multi-user project management system for managing intricate and complex information. Its initial purpose was to allow software development teams to create, maintain, track, and store project requirements on a multi-project basis in a multi-user environment. It has now become more abstract in the type of data it can maintain, allowing the easy addition of new data models and other expansions. Information can be stored in any of several database management systems, and can take advantage of a networked DBMS.

The first and most important feature of the application is that data is stored in a central data repository managed by some database management server; initially PostgreSQL fills this role, but support for others are growing. The repository is fully searchable. An alternative data storage format exists in the form of a locally maintained XML file if the user wishes to use it.

One of the key features Essential Management was designed around is the ability to define and maintain relationships between requirements. Using the software requirement model as an example, our application allows users to define projects; each project is composed of zero or more root requirements, which are typically business level requirements. Each business requirement has zero or more sub-requirements, which either refine the parent business requirement or dive into the functional requirements which allow the business requirement to be achieved. This tree continues to branch and grow deeper until the most basic level that the user wishes to define is reached.

In addition the relationship between parent and child requirements, relationships can be defined between requirements not in the same branch. These relationships may have any meaning the user wishes to define and can be unidirectional or bi-directional.

Essential Management implements the concept of user level permissions, which provides a small measure of security for the projects and their requirements. Additionally, creation of and changes to requirements can be traced to the user who initiated the action.

Finally, the application provides a means to track changes made to requirements during their lifetime so it is possible to determine when a change was made, what information was changed and who edited the requirement.

PHP time management project is a Web-based time management application. You can enter scheduled items, copy items, and view them on a calendar.

A few minor items in the login page for the system were fixed.

LMS (LAN Management System) is the integrated system of networks management designed for various size internet providers (ISP).

That software writed in PHP, Perl and C, works with variuos database systems.

Nelisys project is Open Source Web-based Management System, to manage and monitor system and network including Router, Switch, Wi-Fi Access Point, Server, Networking services, etc.

There are performance and fault management function.

DNA (Deep Network Analyser) is an open, flexible, and extensible deep network analyzer server and software architecture for passively gathering and analyzing network packets, network sessions, and applications protocols.
Deep Network Analyser project is designed to be used for Internet security, network management, intrustion detection, protocol and network analysis, information gathering, and network monitoring applications.

Network Traffic Analyzer analyzes the network traffic on multiple network devices and creates HTML statistics with some network usage graphs. Sometimes it is good to know, how the network is used, how many bytes were received and how many bytes were sent.Therefore, here is Network Traffic Analyzer, which creates simple network usage statistics.


Such statistics can tell you, how good your network connection really is (who cares about what Internet provider say, when was the network down, which time is the best time for downloading large packages of data etc. etc. Or with this software you can just better imagine, how many traffic can your home computer generate.
