Structurile de date Stiva si Coada in C++
Posted by Marius in C++, Data Structures on noiembrie 10, 2009
Stiva este o structura de date logica, implementarea sa din punct de vedere fizic fiind realizata prin utilizarea altor structuri de date.
Elementele componente ale structurii de tip stiva sunt de acelasi tip, ceea ce inseamna ca stiva este o structura de date omogena.
Exista doua operatii de baza cu structura de tip stiva: adaugarea si extragerea unui element. Modalitatea de implementare a operatiilor este data de disciplina de acces: LIFO – Last In First Out. Toate inserarile (push) si extragerile (pop) sunt realizate la acelasi capat al structurii de implementare, denumit varful stivei.

How to: Implement Sparse Matrix Data Structure in C++ Using Array
Posted by Marius in C++, Data Structures on noiembrie 2, 2009
The sparse matrix represents a special type of two-dimensional array consisting of a large number of elements from out of which a very high proportion is occupied by null elements. Thus, the classical declaration of a two-dimensional array in the C++ programming language leads to unnecessary use of memory by storing null values and of the processing capacity.

Implementarea structurii de date Matrice Rara in C++ utilizand masive de date
Posted by Marius in C++, Data Structures on octombrie 30, 2009
Matricea rara reprezinta in tip special de masiv dimensional format dintr-un numar foarte mare de elemente din care o pondere foarte mare o ocupa elementele nule. Astfel, declararea clasica a unui masiv bidimensional in limbajul C++ conduce la utilizarea inutila a memoriei prin stocarea valorilor nule si a capacitatii de procesare.

Crearea unei baze de date in VB.NET
Baza de date este un termen ce desemneaza un fisier structurat, creat in vederea stocarii si administrarii datelor. Administrarea datelor in baze de date vizeaza operatii precum: regasirea, sortarea, gruparea si relationarea datelor.
Stocarea si administrarea datelor se realizeaza prin intermediul sistemelor de gestiune a bazelor de date SGBD. Un exemplu de astfel de SGBD este SQL Server. Mai mult, acesta este un SGBD Relational.
