Types of Database 1. Flat File Database A flat file database is an excellent way of storing a pretty small amount of records. Flat file can be a plain text file. Flat file are generally not a structural relationships between the records. For example a spread sheet application such as Excel can be used as a flat file database. Each row in a worksheet can be a record and each column and a field. Flat file database can also be stored in a dedicated database application such as Access. Installing database

Database Security and Concerns In today’s world, there is a growing amount of complexity when it comes to databases. With that growing complexity, an increasing amount of security concerns arise, such as: unauthorized access and SQL injection. SQL injection is used to attack data-driven applications. SQL injections can manipulate or destroy databases depending on its purpose. Due to the security breaches, measures are constantly put in place in order to prevent anymore from happening. This paper’s

1.1 Graph Databases A graph database represents data and relationships between this data using concepts from graph data structures like nodes, edges and properties. Nodes represents the data entities, properties represent information about the nodes and edges which connect two nodes or a node and a property represent the relationship between the connected elements.
