A database is a collection of records or data that is stored in a computer system. Database tools and applications are designed to help you store and manage data in a controlled and structured manner. A database is a vital system for any organisation that stores mission critical information. The continual failure of a company’s database system will inevitably lead to the demise of the organisation; companies cannot function without a fully working database system.
There are a number of different types of database. The most popular choice in storing data such as personal information, financial records, and medical records is the relational database management system. This type of system makes use of common ‘keys’ to tie related information together with data being manipulated with the SQL data definition and query language. SQL has many strengths for querying data. However, there are some disadvantages inherent in SQL. For example, SQL does not scale horizontally particularly well.
A graph database stores nodes and relationships instead of tables, or documents. Data is stored just like you might sketch ideas on a whiteboard. Your data is stored without restricting it to a pre-defined model, allowing a very flexible way of thinking about and using it.
