A database is a collection of information sequenced and organized in such a way that the computer may be able to source and access it on demand by the operator. Like any other management system, a database management system is a collection of programs and protocols that enable the user to enter, sequence, organize, retrieve and select data on demand. Thus, a database management system (abbreviated as DBMS) can be defined as the cumulated system that helps the user to access and make effective use
information but that not it there are so many other thigns that are stored using technology. Your grades, passport, visa. Where are how do these information get stored. They get stored computers or the technical term databases. Just like that the computers database have also come a long way. Database existed since antient

Database is an organized collection of data, references, or pictures that’s stored in the computer. The healthcare database replace paper documents, file folders, and filing cabinets. Its real-time processing that delivers health information. When a name is put in the computer you can see instant results, just as placing orders or results into the EHR and the information is instantly stored there. A database is composed both of data, and of programs or software to enter and manipulate the data. Both
Relational databases are the most prevalent in today’s database needs for numerous different applications. These databases go by specific rules and adding in a lot of different attributes involves complexity to the system. Especially in the web applications, it gets harder for the relational databases to handle the capacities and possibilities. The web domain thus, becomes the main motivator for NoSQL. Some of the challenges faced by relational databases were the mismatch that resulted when transforming
exploration process. 5.2 Querying of Web of Linked Data using SPARQL. We observed two interesting findings from the history of relational and XML databases. Firstly, from query perspective, it is desirable that an existing query language is extended to retrieve a new type of data, allowing information from two formats to be correlated. For instance, use SQL to query both existing relational data and new XML data. Secondly, from data management perspective, it is valuable to express existing data with
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
on NoSQL database and relational database. (Under the direction of DR. JIANPING FAN) NoSQL database, also called as not only SQL database, is using a different data storage and retrieval mechanism from the relational tables adopted by traditional relational database management system. In the sense of CAP (Consistency, availability and tolerance) theorem, NoSQL database sacrifices some consistency features to get more availabilities and partition tolerances. In most cases, NoSQL database systems
Tablet Assignment A tablet is assigned to one tablet server at any point of time. The master is responsible to keep track of the set of live tablet servers, and the current assignment of tablets to tablet servers, including which tablets are unassigned. If a tablet is unassigned, and place is available in a tablet server; the master assigns the tablet by sending a tablet load request to the tablet server. Chubby keep track of tablet servers. When a tablet server starts, it creates, and acquires an
on database technology have been ever expanding since its introduction in the 1960’s. Today traffic on the internet requires that millions upon millions of records be stored and queried each second. Data must be highly available and quickly retrievable. These requirements put together have given rise to new forms of database technologies collectively called “NoSQL” or “Not Only SQL”. NoSQL eschews the strict guidelines that govern the creation and function of traditional relational databases. These
