To remind you and organize your knowledge a graph is a composition of two types of elements which are nodes and relations. A node can represent a specific type or several types and has its own properties. Relationships apart from their name and their own properties have most importantly a direction of influence. The properties mentioned are collections of keyvalue pairs. They are used to store important information. For example if the node is a person its properties may be name surname age or a list of favorite books. Relationships between nodes in Neo j and in graph databases in general are just as important data as the nodes. We treat them as objects whose existence is determined by the presence of given nodes.
There is no justification for the existence of independent relationships. We will usually associate relationships known from RDBMS Relational Database Management System databases with marking data in a row from one table as being reflected in a specific row in another table. This Email Marketing List will allow us to perform cascading operations when editing or deleting data. When normalizing a data model in an RDBMS we may encounter the need to introduce special intermediate tables between two tables used to link entire groups of rows together. Read also Discover the benefits of TestDriven Development on a daily basis Database selection.
There may still be a belief in many environments that RDBMS are the best for all kinds of tasks. Decisionmakers in the selection of databases may look unfavorably at alternative data storage solutions and Neo j has so far been regarded as such. How to wisely choose the database or databases to be used in the project? First of all the choice should be determined by the tasks facing the application. Already at the application design stage at the database selection stage it is worth considering several issues what operations will be performed on the collected data in the future.
