Basic Informatics in Occupational Risks
Naturaleza de los Sistemas de Información
Information systems
It is an arrangement of people, activities, data, networks and technology integrated with each other with the purpose of supporting and improving the daily operations of a company, as well as meeting the information needs for problem solving and decision making by the directors of a company
Raw Material of Information Systems
Data is represented by symbols, but can only be considered information in a very limited sense
Information System Activities
Capture of input data: Data must be recorded or captured in some way before it can be processed. They can be initially recorded on paper source documents, or they can be captured averaged from a direct input device;
Information flow
Layout Elements
Program Flow Diagram
It is the diagram that outlines the main segments of a program called the main control flow diagram or macro flow diagram. The ones that detail the steps of a module are called micro flow charts or detailed flow charts.
Information Flow Logic
Program Flow Diagram
In program flow diagrams, there are currently three types of structures: Simple selection logic: it consists only of one step followed by another.
Selection logic: requires the testing of some condition that is followed by two alternate branches of program control. This pattern is often called an IF THEN ELSE structure.
Communication Models
Data communication refers to the means and methods used to transfer data between these processing locations.
Types and Uses of Information
Databases
General Applications of Database Management Packages
A database management package allows you to query the contents of a database for answers to questions that are not frequently repeated and that were not planned in advance and therefore cannot be obtained from routine reports.
Components of a Database
Tables: component of a database that stores information regarding a given entity. It should be noted that the tables can be related to each other by means of a key field.
Fields: component of the tables, which identifies each of the attributes of the data to be stored.
Records: data related to an entity, thing or person that is stored in each of the tables in the corresponding fields.
Graphic designers
Types of Design Packages
They are programs that have greatly improved the productivity of design and drawing work. They are used to create, edit, store and produce permanent copies, but the medium is the image, rather than the text.
Design Packages: Computer Aided Design (CAD) is a phrase that refers to the integration of computers and graphic design packages for the purpose of automating the design and drawing process.
Information Management
Service stations
They are special desktop computing units designed for busy people who may not want to type.
Visual display station: is a device capable of displaying the keyed inputs and outputs of the processor on a screen.
Point of sale station: I / O device capable of immediately updating sales and inventory records in a central processor and producing a printed sales transaction receipt.
Analysis of the information
They are the decisions that are made in companies can be structured or unstructured, and that will probably vary according to the level of the management position.
Establecer, evaluar y ajustar objetivos
Desarrollar planes y normas y emprender acciones.
Estimar el rendimiento real y proceder de manera adecuada cuando el rendimiento se aparta de la norma.
Estimate actual performance and proceed appropriately when performance deviates from the norm.
Information Distribution
Although the form (or format) of the input data required varies across districts and programs, the most common is to organize the data into related groups to ensure effective processing and useful output.
Techniques and Strategies
Organizational Standards - Some organizations have standards manuals that specify a consistent design strategy.
Diagram and special shapes: they serve to correct weak points that were detected during the analysis.
Top-down design methodology: requires identifying the highest-level functions of the proposed system from the beginning.
