Databases are store houses of data. Database security is very important irrespective of the database being small or large in order to maintain data integrity and access control. Security begins with having established standards in the data environment. It involves establishing a series of processes and systems to protect the database. Other security measures like firewalls and routers are used for providing external security for the database. Database information security processes involve access control, audits and data encryption.

Database development involves the building and maintenance of databases. In order to create a web site and publish content on the net, a database is required to hold and manage the connected data. The data stored is generated to be displayed on web pages using scripts like HTML. Databases could be simple or complex based on user needs. A flat file model database is sufficient for launching a simple web site. But for web sites involving interaction with users and applications, relational databases may be needed to handle and interpret the vast quantities of data. Database servers with high end capabilities are needed for maintaining complex databases. There are free software and database systems that are available and which can be used to build and publish simple web sites. For complex and large web sites, there will be a cost implication. After a database has been built, it has to be maintained for life. So, a database design should take into consideration future growth potential and needs also in order to be effective for a long time.
