A Flat file database is a database that stores data in a single file (such as .txt or .ini). One record is held in each line of the text file with fields separated by delimiters. There is no structural relationship between the records. A list of names, CNIC number, address and phone numbers written on a piece of paper or typed using a type writer or word processor is a flat file database.

This database file system stores all data in a single directory. There are no folders or paths used to organize the data. This is a simple way of storing files yet this file system becomes increasingly inefficient as more data is fed. While it uses simple structure, this database file system cannot have multiple tables. The first Apple Macintosh 128K computer used this kind of file system known as the Macintosh File System (MFS).

Hierarchical – 1970s - 1990s

This data model organizes data is a tree-like structure similar to the organizational structure. This structure allows the repetition of information using parent/child relationship. One-to-many relationship is created as one parent can have many children but a child belongs to only one parent. This model is the first data base model created by IBM in 1966. It was used in Information Management System (IMS) developed by IBM. Later Microsoft employed it in Windows Registry. This data model replaced the Flat file database system because it was more fast and simple but inflexible as the relationship was restricted to one-to-many.

Network – 1970s - 1990s

Network Database model is conceived as a more flexible model as compared to the Hierarchical model as it can have many-to-many relationship between the children and the parents. Its schema is viewed as a graph in which object types a...

... idea of web-enabled database server was introduced.

Take the example of a student posting a question in his university forum. The student can look up the university forum archive to check whether or not this question has been raised earlier or alternatively a query could be initiated by the server. If a question of similar nature is not found in the database, the student can raise it. Otherwise he/she can refine its question to address the area not covered in the existing database. This forms an intelligent and dynamic information flow.

    In 1977, Larry Ellison, Bob Miner, and Ed Oates founded System Development Laboratories. After being inspired by a research paper written in 1970 by an IBM researcher titled “A Relational Model of Data for Large Shared Data Banks” they decided to build a new type of database called a relational database system. The original project on the relational database system was for the government (Central Intelligence Agency) and was dubbed ‘Oracle.’ They thought this would be appropriate because the meaning of Oracle is source of wisdom.

  • Normalization and Integrity

    1055 Words  | 3 Pages

    Inconsistently storing organization data creates a lot of issues, a poor database design can cause security, integrity and normalization related issues. Majority of these issues are due to redundancy and weak data integrity and irregular storage, it is an ongoing challenge for every organization and it is important for organization and DBA to build logical, conceptual and efficient design for database. In today’s complex database systems Normalization, Data Integrity and security plays a key role. Normalization as design approach helps to minimize data redundancy and optimizes data structure by systematically and properly placing data in to appropriate groupings, a successful normalize designed follows “First Normalization Flow”, “Second Normalization Flow” and “Third Normalization flow”. Data integrity helps to increase accuracy and consistency of data over its entire life cycle, it also help keep track of database objects and ensure that each object is created, formatted and maintained properly. It is critical aspect of database design which involves “Database Structure Integrity” and “Semantic data Integrity”. Database Security is another high priority and critical issue for every organization, data breaches continue to dominate business and IT, building a secure system is as much important like Normalization and Data Integrity. Secure system helps to protect data from unauthorized users, data masking and data encryption are preferred technology used by DBA to protect data.

    Information Retrieval is simply a field concerned with organizing information. In other terms, IR is emphasizing the range of different materials that need to be searched. Others researcher said that IR is the contrast between the strong structure and typing a database system with the lack of structure in the objects typically searched in IR. The actual process in information retrieval systems is it has to deal with incomplete or under specified information in the form of the queries issued by users. IR uses the techniques of storing and recovering and often disseminating recorded data especially through the use of a computerized system.

It is being sent from one computer user to another user. Example of the word processing documents is the Microsoft excel. It is spreadsheets that being produce by the Microsoft for calculating, graphic tools, pivot tables and a macro programming language. This is because the files may have internal structure but it is considered as the non-structured data because the data in the database is still unstructured.
