Database theory

Database theory Why relationships are important in a database. Relationships on a database establish a connection between two associated and logically related tables, that each have similar data. An example may be a table that contains names of certain students, and another table that contains the student's ID, the code of library books, and the dates on which each specific student checked out that particular library book. Without association of relationship on the relational database, the two

1) How many records does the file contain? How many fields are there per record? There are 7 records (21-5Z through 31-7P) and each record contains 5 fields (PROJECT_CODE through PROJECT_BID_PRICE). 2) What problem would you encounter if you wanted to produce a listing by city? How could you solve this problem by altering the file structure? There is not a field for city, only manager’s address. In order to get a listing by city, you would have to break up the address into address, city,

Responsibilities in the project: In this project we required Experienced person in database tool, and also we required a good design to done our project without any complications and provide security on each every step in designing and modelling .So that we organised a structure to done everything in a systematic way to done the project in a smooth way 1. Collecting data and Analyse the Business need and plan duration 7 days. 2. Database design duration will be 8 days. 3. Define calculation and reports duration

History of Database Technology Past and Present The term database was popularized with the growth of the computer industry and is typically thought of as software used to store, index, manipulate, and retrieve information (Vaughn). Database software has been in use since the Census Bureau used a punch card system to meet the requirements for the collection, sorting, and reporting of data for the 1890 census (National Research Council). These earliest databases were flat file databases. The flat-file

done to generate the following artificial CSV files. There was not any disposal action taken because the data itself was from an open source that is available for public. ------------------------------------------ The weakness of the relational database was unfolded by the rise of web-driven application (Lake and Crowther, 2013; Dede et al., 2013), whereas

problem has a solution. In order to come up with a good solution, the root of the problem has to be determined. The scope of the problem must be established well before making the first few steps of the study. One has to get a hold of the basic theories and principles regarding the problem, justify the impact of the problem to the society, and consider the future customers of that “would-be “solution. Before designing solutions, related literature must be examined first. This may ease off confusion

INTRODUCTION MongoDB is one of numerous cross-stage archive situated databases. Named a NoSQL database, MongoDB shuns the customary table-based social database structure for JSON-like archives with element constructions (MongoDB calls the organization BSON), making the combination of information in specific sorts of utilizations less demanding and quicker. Discharged under a mix of the GNU Affero General Public License and the Apache License, MongoDB is free and open-source programming. Initially

Background The weakness of the relational database unfolded by the rise of web-driven application (Lake and Crowther, 2013; Dede et al., 2013), whereas non-relational database gained their popularity (Li and Manoharan, 2013; Parker et al., 2013;
