A Database is a collection of records. Database management systems are designed as the means of managing all the records. DBMS is a software system designed to allow the definition , update , retrieval and of databases.
TYPES OF DATABASE
• Relational database • Document oriented database • Embedded database • Graph database • Hypertext database • Operational database • Distributed database • Flat file
Relational database• A relational database is a database that has a collection of tables of data items.
• Data in a single table represents a relations.
• Tables consist of rows and columns.
• The columns constitute the attributes.
• The rows constitute tuples.
• Row-A data set representing a single item.• Column-A labeled element of a tuple, e.g. "Address" or "Date of birth”, of multiple data item.• A primary key is used to uniquely identify each row. • The foreign key a column or group of columns in one table
that points to the primary key of another table. .
Document oriented database
• A computer program designed for storing, retrieving and managing document oriented information.
• Documents inside a document-oriented database are similar to records or rows in relational databases.
• Do not store data in tables with uniform sized fields for each record.
Embedded database
•The databases consist of data developed by individual end users.
•Examples of these are collection of documents, spreadsheets, presentations and other files.
Graph database
• A graph database is a database that uses graph structures with nodes, edges, and properties to represent and store data.
• A graph database is any storage system that provides index-free adjacency.
• This means that every element contains a direct pointer to its adjacent elements.
Hypertext database
• Hypertext databases are particularly useful for organizing large amount of disparate information.
• Hypertext is text displayed on a computer display or other electronic devices with references to other text which the reader can immediately access.

DISTRIBUTED DATABASE
• A database in which storage devices are not all attached to a common processing unit.
• It may be stored in multiple computers located in the same physical location , or,
• May be dispersed over a network of interconnected computers.
Flat File
• A flat file database is a database that stores data in a plain text file.
• Flat files are ideal for small amount of data.
• Each line of the text file holds one record, with fields separated by delimiters, such as commas or tabs.
