2 PROJECT PART
2.1 Development of an automation project
2.1.1 Stages of the project life cycle automationby time, size and complexity of automated systems are growing. Radically changed and keep changing the requirements of not only the main features and service capabilities of systems but also to the dynamics of their changes. Design and methodological support development ICS including software and databases is traditionally supported by many standards and proprietary techniques.ISO/IEC 12207: 1995 «Information Technology - Software Life Cycle Processes» is the main normative documents regulating the composition of the software life cycle processes [ 3]. It defines the structure of the life cycle having processes, actions and tasks to be performed during software development.process is divided into a set of actions and each action is a set of tasks. Every process or task operation is initiated and executed by another process as needed and there is no predetermined sequence execution. In addition, communication input data is saved. Model of the software life cycle includes:
- stages
- results of work at each stage
- key events which are points of completion and decision making
Stage is a part of the process of the system development limited by time frame for release and ending with a particular product which is models, software components, and documentation. Also, the relationship between processes and stages are determined by the model of software life cycle.
. 1.2 Anticipated risks to the life cycle and their descriptionintroduction of any system includes some basic steps:
- the study of the existing fleet of computers and peripheral equipment in the case of non-compliance to the requirements of finishing rolling out the system
- check the availability of necessary for the system to the operating system on the server
- final testing of the developed project on deployed vehicles
- training of staff
- start of operation of the system
The deployment phase of the system includes the deployment of a database server, the installation of the operating system on it. Finally, it is the installation of the developed system by IIS and Internet access for sharing the system by the Internet.deployment of technical, information and software tools necessary to conduct there is necessary to final testing of the system and verify the proper operation of all system modules., you need to train users on the system. There is necessary to conduct training for all users who will work with the system.the first stage of operation of the system is necessary to fill all the raw data:
- details of organization
- structure of units
- employees of organization
- etc.
These can be made in the process of entering documents as required but is recommended to make a pre-existing data, thus creating a complete structure of the organization.
. 1.3 Organizational, legal software and hardware-based securityusing any software necessary to follow a few basic rules, namely:
- use only licensed software
- follow the release of software updates and install them on time
- install only proven software purchased from authorized suppliers
To prevent contamination of the information you need to differentiate user access, to install and configure anti-virus program, with constant updating of virus databases, and install and configure the program «Firewall» to close the threats from the external network, such as Internet .
2.2 Information support tasks
2.2.1 The information model of the problem and its descriptionand functional development methodology involves modeling the information model:
- the relationship of input, output and results-based information flows and functions of the domain ie structural and functional diagrams
- data information base necessary for the functioning of the automated system ie entity-relationship diagram
