Development of Programs and Systems
In computarizar.pro we offer
you a professional service in Systems Engineering and in
Software Programming.
We use the best operating systems and the best programming languages most
universally used. We work with modern tools, to implement your
project in quick efficient way and at a very accessible cost.
Our software programming service, will help you to personalize your computer
environment, with software programs, designed according to your
specific needs, and personal cultural style.
The computing to your service and not you to the service of a product!

TOPICS OF PROGRAMMING
We present you the main programming topics, in which we have worked for
about 12 years until the present. From the year 1998 we are dedicated in
almost exclusive form to the topics of Internet, to the design of
web pages and the development of applications for the electronic commerce.
DESIGN OF WEB PAGES
In the section WEB PAGE, you will find very good offers to be
present in Internet at a good level and a very accessible cost. Your web
page, is an important instrument of communication that can be very
useful or indispensable for your personal, professional or
commercial development.
In the TRAINING section you have advice on this topic.
PROGRAMS for INTERNET
The programming languages JAVA and JavaScript allow us to implement
applications that execute in any computer that has a Navigator of
Internet that is Java/JavaScript compatible (Explorer, Communicator,...
they are compatible).
Are denominated APPLETS the small programs written in language
JAVA. They are included in the web pages to improve their
functionality. The applets allows to create special graphic effects
and multimedia presentations, they facilitate the access to great
quantity of services, such as: ecommerce, telephone in Internet,
chat rooms, etc.
If you need dynamic web pages, or you want to include in your
web page advanced functions, the most effective solution consists
on using Java/Script. These programs execute in the user's PC and they
are independent of the platform type.
Are called CGIs programs (Common Gateway Interface), to those
that allow you to access to the advanced computer resources, from a page web.
The electronic commerce, query to a big database, web pages configured
according to the user's preferences, all they are examples that require of
the development of applications that they execute in a web Server.
If you need to register important volumes of data that are entered by
means of a page web, the same thing that if it offers access to databases,
from a web page, the most effective solution is a CGI program.
In the TRAINING section you have advice on this topic.
DATABASE DESIGN
Development of databases for the commercial, scientific and technological
applications. Programs for the process of data, you restructure of bases,
audits and obtaining of statistics.
Web Pages and CGI applications to access to databases in servers.
Consultation operations, registration, upgrade.
Development of applications for the handling of data (screens, forms),
emission of reports, automatic operations of process of data using the
language S.Q.L and verification.
Programming of applications using the main database managers:
ORACLE, INFORMIX, SyBASE, MySQL, PostgreSQL, ColdFusion.
SYSTEM UNIX / LINUX
The operating system UNIX and their compatible ones (Linux, Solaris,...)
are fundamental in the modern computer science's development.
Their graphic environment (Xwindows) has given origin to the current
Windows systems of massive diffusion. For the own origin of Unix, in the
scientific environment, from very early, it included the most advanced
techniques of communication of data, being today, the main operating
system of the servers of Internet.
Programming in shell: sh (Bourne), csh (C), ksh (Korn shell).
Commands: awk, cron, uucp, greep, cpio, tar, mkdev, fsck,...
Development tools: C/C++, Perl, Fortran, Xwindows,...
Programming of TCP/IP applications for Servers of Internet.
Programming of applications for the APACHE Web Server.
ADMINISTRATION PROGRAMS
Development of projects, implementation and maintenance of systems, for
the following functions and classic areas:
A) ADMINISTRATION OF STOCK
B) BILLING
C) LIQUIDATION OF SALARIES
D) ADMINISTRATION OF SERVICES
E) ACCOUNTING
F) COMMUNICATION OF DATA
G) ELECTRONIC COMMERCE
The implementation can be made in Windows and Unix.
CALCULATIONS OF HIGH PRECISION
Numeric integration, resolution of equations systems, numeric
simulation, elaboration of mathematical models, minimization of costs,
generation of random numbers, and other computations.
There are also models and routines to make Calculations of High Precision,
which can be very useful in theoretical and practical investigations. For
example, if we want to know which are the first 800 figures of the number
Pi=3.14159265..., still when we know the formula that defines it, the maximum
precision of the computers more advanced (128 bits), they hardly allow us
to achieve about 40 exact decimal digits.
With an OBJECT for High Precision calculations you can easily achieve the
precision that is required or the maxim that allows the memory of the
computer or the reasonable calculation time.
There is here, 800 exact figures of the Pi=3.1415926535897....
