Easy to specify metadata/schema for the data. Rigid structuring of the data leads to highly efficient methods to read and write. Many possibilities for security control. Can support vast amounts of data, and scales better than the file system. <br> Disadvantages: rigid. Not for unstructured data(such data must be stored as blob and cannot in general take advantage of database features). For example, markup, large text files, audio and video: could use document databases instead. Graph databases are better for querying/finding relations/paths between entities. Big blobs of data might be better to just use files, since the database system is then just a useless middle layer.</p>","names":[[["Relational databases advantages & disadvantages",""]]]}},"style":"Note"}
