Database transaction is an indivisible and irreducible series of database operations such that either all occur, or nothing occurs

A DBMS usually acquires locks on data which may result in a loss of concurrency or implements multiversion concurrency control. This requires adding logic for the application to function correctly.

Frequently Asked Questions

What is a crossword?

Crossword puzzles have been published in newspapers and other publications since 1873. They consist of a grid of squares where the player aims to write words both horizontally and vertically.

Next to the crossword will be a series of questions or clues, which relate to the various rows or lines of boxes in the crossword. The player reads the question or clue, and tries to find a word that answers the question in the same amount of letters as there are boxes in the related crossword row or line.

Some of the words will share letters, so will need to match up with each other. The words can vary in length and complexity, as can the clues.

Who is a crossword suitable for?

The fantastic thing about crosswords is, they are completely flexible for whatever age or reading level you need. You can use many words to create a complex crossword for adults, or just a couple of words for younger children.

Crosswords can use any word you like, big or small, so there are literally countless combinations that you can create for templates. It is easy to customise the template to the age or learning level of your students.
