Welcome to Class !!
We are eager to have you join us !!
In today’s Computer Science class, We will be discussing Forms of Database. We hope you enjoy the class!
TOPIC: FORMS OF DATABASE.
There are various forms or ways by which a database can be set up. They include:
- Flat file database
- Relational database
- Hierarchical database
- Network database
- Operational database
- Distributed database
- End-user database
- FLAT FILE DATABASE: This is the traditional data file storage system ideal for storing small amounts of data that needs to be humanly readable or edited by hand. They are called flat because they contain only one table. The disadvantage is that flat files can be corrupted easily.
- RELATIONAL DATABASE: This is the most common of all the different types of database, files are organized in tables called relations. Each table has a key filed which is used to connect to other tables. Hence the tables are connected through several key fields.
- HIERARCHICAL DATABASE: This form of databases has a tree-like structure. In this database, a single table acts as the root of the database from which other tables are connected. All windows operating system operates a tree-like database.
- Mention the forms of databases.
- Explain relational database
- NETWORK DATABASE: This database was designed to solve some of the more serious problems with the hierarchical database model. Visually network database looks like a hierarchical database.
- DISTRIBUTED DATABASE: This form of database is stored on different location connected by a client/server network. Data that is been stored are transmitted through a network. Each workgroup may have their own database and are connected through a network.
EXAMPLES OF DATABASE
- Microsoft Access
- Microsoft SQL server
- Write short notes on the distributed database and flat file database
- What is a database?
- What is a relational database?
- What differentiate relational database other forms of databases?
