Oracle

 Oracle Database is a database management system from Oracle. This DBMS is also actively used by large companies and costs a lot of money, but in return it provides great functionality and reliability. Therefore, Oracle Database and Microsoft SQL Server are serious competitors to each other. The results of Oracle in the rankings are not so clear, for example, according to PYPL and DB-Engines, Oracle Database ranks first, according to Stack Overflow Oracle is in eighth position, according to surveys of Oracle software companies in fourth place in popularity. If we take into account only a couple of ratings, Oracle can even be put in first place, but if we take into account all the results, then Oracle cannot be put in first place, therefore, in our rating, this DBMS occupies the third line.

Choosing a rod with the right features

 


Choosing a rod with the right features

Rod action


This often used concept means the temporal characteristic of the bending of the rod under load. If, after removing the load, the rod returns to its previous shape in a split second, this is a very fast action. When it straightens out over a longer period of time, it is a slower build. In the case when the entire whip is bent, it will take longer to restore its shape after removing the load. Rods in which the entire whip is bent, including the handle, are called parabolic.


Based on the name itself, it is clear that the action is how the rod is “built”, from what material, what is its geometric shape and linear dimensions.


The determining factors for the system are the physical properties of the material used - specific gravity, resistance to compression and stretching. A properly built rod, if a weight is attached to its tip, bends smoothly, without fractures, starting from the handle, if any. The bend should not be uniform along the entire length, but increasing from the butt to the top, without sharp fractures and without straight, rigid sections.
