Titolo: Fatturato azienda - Andamento borsa

Salve,
C'e' modo di verificare il fatturato di una azienda a partire dal suo nome? 
Eventualmente (trattandosi di una spa) è possibile anche vedere il suo 
andamento in borsa?
Grazie a tutti

tenendo presente quanto segue, direi di si:
 
OVERVIEW
The exact job definition of an Oracle Database Administrator's (DBA's)
responsibilities are hard to find in print. It would great if those
responsibilities could be easily bundled into a nice package say like the
role of an accountant. However, uniqueness within companies and the
distributed enterprise has made that seemingly impossible. As one career
description defines it: DBA - Administers and controls an organizations data
resources. Use Data Dictionary software packages to ensure data integrity
and security, recover corrupted data and eliminate data redundancy, and uses
tuning tools to improve database performance. Can it be this easy to define
the role of a DBA?
WHAT EXACTLY IS A DBA?
The position of Database Administrator seems to mean different things to
many organizations. In smaller development organizations, the duties are
much broader than in a major corporation. Whether a company is performing
development or utilizing third party packages, will further define the role
of the DBA position. Knowing what is expected of the role and how the
position fits within the company business operations is critical.
For many companies, the DBA role may begin with one or two servers running
small workgroup or departmental applications. Within a few months, the
organization can suddenly find themselves supporting applications around the
clock without the proper support or staffed resources. Lack of resources
then escalates into customer dissatisfaction, over-work, and staff
frustration that leads to employee retainment problems.
An important factor is to define the roles & responsibilities, is ensuring
there will be an infrastructure in place to support existing and new
business processes. For most organizations, confusion arises when the skills
of the IT staff normally overlap without a clear delineation of
responsibility. To be most productive, the skills of the staff should
intersect with the responsibilities being clearly defined. It is important
to define, establish, and communicate the roles and responsibilities.
Qualifications for the role of DBA are quite diverse. The DBA must possess
technical knowledge in the sense of the interpretation of database design
models. A DBA must also possess a knowledge of the security, data retention
and disaster recovery requirements of the company. Knowledge of the database
performance and administration requirements of company application systems
is also a requirement. Business skills such as multitasking, analytical
skills, active listening, oral and written communication are significant
requirements as are technical skills in operating systems, networking and
database management software. A DBA should also be familiar with software
tools and languages for use by the organization to produce stored
procedures. A DBA must also have an understanding of tools used to test,
monitor, tune and administer the company databases.
In a mainframe environment, the typical duties of a DBA consisted of talking
with a few analysts supporting a single operating system along with a couple
programmers who supported the transaction processing applications. In a
distributed open systems environment, the role of the DBA is expanded by
various operating systems, applications, combined with a greater number and
diversity of people. A typical DBA must deal each day with groups in many
functional areas, including network management, systems management, training
and application development. DBAs must be knowledgeable enough to determine
where in the system the problem actually occurs. DBAs should assist with
incorporating consistent adherence to standards procedures, and naming
conventions. Not having standards and procedures leaves a project more
susceptible to risks and adds additional complications when no one remaining
on the team understands the code left behind by previous employees.
KEY DBA ENABLERS
Several factors are critical for the success of the DBA role:
Adaptability:
Configuring systems and software for the ability to change as business needs
dictate while maintaining the production environment and servicing the user
community
Availability:
DBAs must be prepared to respond rapidly to issues
Control:
DBAs must control the metadata, data definition process, and access
Tools:
Utilizing fully featured tools are critical to supporting fast moving
projects.
Management of the Oracle database requires a variety of knowledge and
analytical skill. Architecture of the database, performance tuning and high
availability are just a few issues which face the Oracle DBA. This paper
will outline critical DBA skills, typical responsibilities and roles. But
first, we have to describe the type of job responsibilities outside the role
of DBA, but within the IT team, that empower the DBA to be fully effective
in their job role and career development.
System Administrator
The System Administrator is responsible for server maintenance and
configuration. They install, upgrade and tune the operating system.
Responsibility for implementing the backup/recovery plan falls into Systems
Administration as does the development and implementation of a Disaster
Recovery plan. The System Administrator works closely with the DBA and the
Network Administrator.
Network Administrator
The Network Administrator is responsible for the network architecture,
maintenance, performance and monitoring of the network. The Network
Administrator works with WANS, routers, subnets, etc. The Network
Administrator works closely with the DBA, System Administrator and Desktop
Administrator.
Desktop Administrator
The Desktop Administrator is responsible for the PC network at the workgroup
level, setting standards for LAN software and hardware, and testing and
configuring the network software on the client and file servers. The Desktop
Administrator maintains file servers, terminal servers, and troubleshoots PC
and LAN issues. The Desktop Administrator works closely with the Systems
Administrator, DBA and the Network Administrators.
Developer
The development staff is responsible for the design, and creation of the
various programs making up the business application. Developers should be
familiar with forms, PL/SQL, 3GL languages, and Client/Server development
skills. Developers work closely with the Business Analysts, the Application
Administrators, and the Application DBA.
Application Administrator
The Application Administrator is an individual with an in-depth knowledge of
the use of the applications. The Application Administrator is responsible
for the configuration of the application from the users viewpoint, enrolling
end-users, and trouble shooting problems for the help desk. The Application
Administrator role works closely with the Business Analysts, Developers,
DBA'S, and Desktop Administrators.
Business Analysts
The business analyst is responsible for implementing the applications and
facilitating any transition required from legacy systems. The Business
Analyst has in-depth knowledge in the business functions of the corporation
and other areas of the system. The Business Analyst works with the project
managers, Developers, end users and the Application Administrators.
TYPES OF ORACLE DBAs
As scope, size, and complexity of systems expand, the DBA role can be broken
into several areas of responsibility or specialties. For smaller
organizations, this may not be necessary, but in larger organizations DBA's
tend to be broken out into areas of specialty.
Database Operator
The database operator provides manual monitoring of the database console,
tape mounting, and critical jobs. The database operator verifies backup or
archives ran correctly, restarts the backup or archives if necessary, and
monitors the available free space in the backup and archive directories. The
Database Operator can be supported by existing staff or filled utilizing a
third party tool.
System DBA
The System DBA's role is critical for the initial database architecture, for
new projects or application upgrade analysis, and capacity planning. A
System DBA not only has experience with Oracle and advanced features such as
replication, parallel server, and partitioning, but also a background in
system and network architecture. Without a System DBA, many organizations
later find themselves against a wall with I/O, performance, storage
management, backup, and capacity problems.
Application DBA
The Application DBA provides database modeling support and development of
the logical database. The Application DBA develops applications
architecture, performs SQL tuning and supports the applications. The
Application DBA works closely with Developers, the System DBA and Business
Analysts.
DEMANDS OF A DBA
· According to a recent Computerworld survey, the average, information
technology professional works over 50 hours per week.
· Over half of the surveyed IT workers said they "occasionally" miss getting
home for dinner; with 28% saying "frequently."
· Almost half, work an average of six hours on Saturdays and Sundays and
said they work while on vacation. 61 % of IT professionals interrupt their
vacations to call and check on things at work with 25% of them bringing
along a laptop computer, pager or cellular phone to stay in touch with the
office.
WHAT TYPE OF DBA IS REQUIRED FOR AN ORGANIZATION?
DBA's skill types range from operators to Senior System or Applications
DBA'S. What type of DBA, and how many are needed? If an experienced DBA is
hired only to monitor Oracle and ensure backups and jobs are completing,
they will probably become bored and leave. On the other hand, if you hire a
single DBA not only to administer the databases, but the systems and
applications for the 20+ servers, they will soon burnout and leave.
If all that an organization requires is an additional resource to monitor a
database application via a monitoring tool, reacting when the tool tells
them there is a problem, then employ a junior DBA or outsource the function.
If the DBA is a quick study, you will be lucky if they stay a year in a hot
job market.
A junior DBA is indicative of a resume that is full of Oracle projects but
most involved third party applications that happened to have Oracle
installed as their backend repository. Junior DBA's are too inexperienced to
address recovery issues or database internals, but are competent with
monitoring database health.
For larger companies, a more senior individual(s) may be needed to
participate fully in the companies IT lifecycle. A senior DBA will have a
broad range of skill sets to map to business operations and architectures.
The Senior DBA may focus entirely on one subject matter such as performance
tuning, while another team member is responsible for backups and recovery.
In either scenario, the DBA role should follow these fundamental processes:
Identify the root cause of the problem, resolve database problems, and
develop methods for preventing the problems
· Review databases with developers, users, and management monthly to detect
system or operational problems.
· Coordinate on a timely basis to resolve problems discovered or brought to
the attention of the DBA.
· Implement and maintain methods and procedures for monitoring and
maintaining database systems.
Maintain and improve technical skills, environment and application knowledge
· Identify training available in areas of needed improvement and attend
training as directed.
· Four hours monthly in reviewing available World Wide Web sources or trade
publications
· Review existing applications by study of documentation and discussions
with application developers.
· Develop a knowledgebase of the database, environment and associated
software.
· Assist with support for all application development
· Review reports/logs/dumps and other data to recommend corrective actions
to maintain database performance and efficiency
· Coordinate performance and tuning actions with database developers
Review and evaluate status of assigned projects and their impact upon the
database systems
· Monitor project progress, discusses major problems with other analysts and
management
· When discovered, resolve delays affecting project completion
· Provide weekly status reports to Management
· Conduct database walkthroughs with programmers, analysts, and users prior
to finalization of major recommendations
· Review databases thoroughly before recommending new systems or system
changes
Provide user support through meetings, presentations, and preparation of
documentation
· Establish and maintain effective communication with user community
· Participate actively in meeting with staff and users, demonstrate ability
to interpret user needs by preparing thorough summaries and recommendations
· Develop and update user documentation
Prepare and review database specifications, including testing and controls
· Review database recommendations thoroughly with users and management,
resolve problems or differences before final recommendations are made
· Study new database design principles, and developing knowledge of database
principles by applying them in projects
· Gather information from users and staff when required by project tasks, to
be evaluated by supervisor through review of work, discussion with users,
and review with other analysts
Prepare budgets, planning documents and maintain service contracts
· Prepare requested material on time. Prepare requested material for fiscal
year by stated deadlines
Design, create, and maintain physical and logical databases
· Participates in logical model design or walkthroughs of the logical model
design to gain an understanding of the logical model design. Present
physical implementation concerns to the design teams and management
· Create physical databases using sound design principles including
documentation of the creation and access procedures
· Create, tests, and monitors backup procedures for the physical or logical
databases
· Maintain the physical database by monitoring and recommending changes as
needed to management. Create quarterly reports on physical storage needs,
memory requirements, and database upgrades projected for a two year time
span
 
TRAITS AND RESPONSIBILITIES OF A DBA
Many organizations tend to concentrate on technical knowledge and overlook
personality. Like most IT roles, the role of DBA is customer-service
oriented. The DBA will have to interface with a variety of people: users,
developers, administrators, vendors, and managers.
Consequently, these traits should be consider when filling the DBA role:
· Communication skills
· Confidence
· Curiosity
· Detail oriented
· Determination
Base Responsibilities
Architecture
· The DBA needs be familiar with sizing, file placement and specification of
storage media. Expertise in RAID, fail over, networking, disk shadowing,
solid state disks, and their application to the Oracle database environment
are important. The DBA needs to be familiar with installation and updates
for the database server platform. For the UNIX operating system, DBAs should
be familiar with the drawbacks and benefits associated with use of raw
devices.
Availability & Maintenance
· One of the jobs of a DBA is monitoring and tuning of the database.
Monitoring and tuning requires a detailed understanding of the Oracle data
dictionary, TKprof, Explain Plan, cost based, rule based optimizers indexes,
use of hints, and SQL statement tuning.
Backup and Recovery
· A DBA must understand all of the backup and recovery options. Use of the
import and export utilities, cold and hot backups. Recovery scenarios are
subject matter that a DBA must understand.
Business Processes & Requirements
· A DBA should possess a sound understanding of the business requirements
and how they map to database methods and systems
Security
· An understanding of Oracle security is critical to the DBA role. Knowledge
of roles, profiles, system, and object level privileges is essential for a
DBA. In addition, understanding how the operating system security interacts
with Oracle is equally important.

Una spa possono decidere o meno di quotarla, anzi e' rarissimo e
difficilissimo quotare una spa
ricorda poi di vedere su tutti gli indici ( mib, mib30, midex, numtel )
( p.s. quota un po' meglio, magari scrivendo sotto alla parte quotata e
quotando solo il minimo indispensabile)
