OPTIMIZACION LOCAL DE CONSULTAS.

To name your story, you have to think about the overall message and what you want your audience to understand from the story. Also, make it relevant and easy to remember.

The ending of a story is essential. We all know that if the ending is weak, what happened before loses its importance. So make it unpredictable, but fair. A resolved ending answers all the questions and ties up any loose threads from the plot.

This is the closure section of the story.
See examples of possible outcomes below:

• all problems have been solved
• it's clear how each one of your characters ends up
• your main character is transformed by the challenge

el objetivo del procesamiento de consultas en un ambiente distribuido

The middle of the story is where you add layers of complications that will lead to the end. Reveal more about the character's journey. Did their personality go through changes? How did they overcome the challenges? And as you build up the story’s central conflict, make it more personal to that character. Also, from the middle act, you have to lead into the final act.

There wouldn't be any tension and excitement in your story if there weren't any obstacles in your character's way.

A story is nothing more than a character overcoming a series of difficulties to reach the desired goal. Obstacles usually create suspense and conflict. In overcoming obstacles, there is growth: weak becomes strong; hatred turns into love; sadness into happiness; wrong into right; lies into truth; or evil becomes good.

See a few examples below:

• stopping a meteor
• finding a killer
• finding love

Para procesar una consulta local solo se hace referencia

In the beginning of the story (or the exposition), you will need to introduce the setting and characters. You might also want to introduce the main conflict. This part of the story is important because it gives the reader necessary background information and maybe even a first insight into a character’s personality.
