At its simplest expression, a database is a gathering of information, here called data, stored on a server. The data is organized in a way it can easily be retrieved, managed and edited in significant ways by the end-user. The data could be something very simple such as personal information about clients or customers. It could also be inventory, sales, calls or anything anyone needs to track. This part is called the back-end. To present the data in a consequential way to the user, web developers create a web site and easy to use database applications.
This part is called the front-end. Even if there are many other database models such as hierarchical and network modelsthe relational database model is the most common. To access and interact with the data contained in a relational database, its user needs to use a relational database management system RDBMS.
SQL is the language most IT experts use to interact with relational databases. These interactions are called transactions. To be efficient and accurate, transactions must be ACID atomic, consistency, isolation, durability.
Atomic means the transaction is all or nothing. Consistency refers to the fact that the database must remain in a consistent state before and after the transaction. Isolation means all transactions must be independent of one another.
Durability refers to the fact that a transaction cannot be undone after the user has been notified of a successful transaction.
There will be a series of calls or queries made to send the money from one account to the other. All calls must be answered and completed in order for the transaction to be completed. Each call made to the database will only be related to our transaction isolation. Examples of SQL-based databases citizens use every day include banking systems, computerized medical records, and online shopping to name just a few.
NoSQL refers more to what it is not then to what it is. It refers to a language system not using SQL. It is mostly used for unstructured data in situations where the ability of the database to accept create or access get large amounts of data quickly is required. It offers great flexibility with alternative data models ex. It is much less rigid than the transactional structure of SQL but it can get much messier! NewSQL could be referred to as the modern relational databases languages.
These are based on the relational database model and the SQL query language but offers better consistency. Some of them offer solid ACID guarantees.
This was just a brief introduction to the newest languages.The database is a collection of inter-related data which is used to retrieve, insert and delete the data efficiently.
It is also used to organize the data in the form of a table, schema, views, and reports, etc. For example: The college Database organizes the data about the admin, staff, students and faculty etc. But if there is any mistake, please post the problem in the contact form.

What is Database The database is a collection of inter-related data which is used to retrieve, insert and delete the data efficiently.Database basics.
A database is a structured set of data held in a computer or server. Structured is the key word here. Structured data is organised in ways that computers and hopefully humans can understand.
Types of databases and DBMS (with examples)
My system is unable to parse my data or intentions. The formula in cell C1 will calculate the sum of 5 and 5, and return an answer of Now that we're database experts, let's drill down into the types of databases.
We'll see that databases can get much more complex than storing data in cells, but they are always used to store and organise data. Are spreadsheets databases? Spreadsheets are a type of database wherein data is contained by workbooks of one or more worksheets. Within worksheets, data is organised into columns and rows of cells. This is organisation. You can compare databases vs spreadsheetsbut spreadsheets are databases.
A DBMS is software for creating and managing databases. DB-Engines lists over systems representing 11 models of organising data. Let's explore these models in order of popularity, along with common systems and use cases for each.
Tier 1: ubiquitous, used everywhere and by everyone. Data is organised into workbooks of tables containing columns and rows. The terminology for a RDBMS is databases of entities characterised by attributes and records thereof.
The defining characteristic of relational databases is schemas. Schemas define relationships between entities and formatting within attribute records. For example, a schema may specify stores have sales and sales have dates, which are expressed yyyymmdd. Since its introduction inRDBMS has largely superseded navigational databases and dominated databasing in many sectors and industries. RDBMS has weathered successive challenges posed by supposed disruptors, partly by accommodating changing needs.
For example, some systems of RDBMS have been expanded with non-traditional features, such as user-defined data types, non-atomic attributes, inheritance, and hierarchies.What is Dbms. Big and small company use DBMS according to their requirements. We have listed all the 25 famous Examples of Database Management Systems.
So here is the list of Popular Database management systems. MySQl was found n the year of MySQL comes among the largest open source company of the world. MyQSL is so famous due its high efficiency, reliability and cost. Along with linux, php and apache it also have lamp technology. MySQL is providing certification and training of Mysql server. MS- Access was developed by miscrosoft and it is a computer based application that is used to create and maintain computer based database on desktop computers.
This can be used for personal use and for small business that needs a database. It stores information in its own format that is based on jet database engine and it used a graphical user interface that makes it easier to work.
Oracle database is developed by Oracle Corporation and it is the fourth generation of Relational database management system. Oracle database is used mostly by big companies that need to manage a large amount of data.
Oracle database is very flexible and it most useful features are integrity constrains, triggers, shared SQL, and Locking. DB2 is also used to store data for large companies. It is an relational database management system and its extended version also supports object —oriented features.
The main problem with DB2 is its cost. As its name shows, it was developed by Microsoft. Microsoft has produced many versions of SQL server depending upon the customer demands. It was developed by Filemaker inc. It has a database engine with graphical user interface. It can be used for both windows and mac. It gives many security features that allows user to alter database by simply dragging new element into forms, screens and layouts.
It stand for not only SQL. It is different from other database management system as it is a non-relational database management system. It is used in distributed data stores like in google and facebook that collects terabits of data every day. It is used to store huge amount of data of social media sites that SQl Servers can never do.
It is developed by PostgreSQL development group. This is and open source database that is free to use under free software license. Fox pro is the combination of both dbms and rdbms. Fox pro supports multiple relationship between DBF Files but it lacks transactional processing. Red Brick is developed by IBM corporation and it can handle large amount of data.
This is very easy to install and manage. Ingres Database is an open source relational database management system that supports a large number of government applications. Ingres is a cross platform database that is acid compatible and fully transactional. Adabas was initially launched on IBM Mainframe.
Adabas recently produced 8. Unidata was originally developed by Unidata corporations and it is an extended rdbms. Unidata has its own programming language unibasic and own query language called uniquery.This document describes how to install and configure the products available on the Oracle Database Examples media.

It includes a number of scripts and sample applications that you can use. Oracle Spatial is an integrated set of functions and procedures that enables spatial data to be stored, accessed, and analyzed quickly and efficiently in an Oracle database. Spatial data represents the essential location characteristics of real or conceptual objects as those objects relate to the real or conceptual space in which they exist.
Oracle Spatial Demos provide SQL schema and functions that facilitate the storage, retrieval, update, and query of collections of spatial features in an Oracle database.
SQLJ consists of both a translator and a run-time component and is smoothly integrated into the development environment. These programs provide examples of the data types, calling conventions, syntax, and semantics of C. The installed demos illustrate the use of OCI features. The control classes enable the applications to connect to the database and create resources like statements and resultsets.
The data classes contain various types of data. The object classes and methods provide a navigational interface to access and manipulate objects.
Oracle provides a set of JDBC drivers that you can use for debugging the code and other deployment scenarios. These drivers can access Oracle Database release 8.
You can extend the supplied knowledge bases depending on your requirements.Accessing Data from a database is one of the important aspects of any programming language. It is an absolute necessity for any programming language to have the ability to work with databases. C is no different. It can work with different types of databases. But with every database, the logic behind working with all of them is mostly the same. In working with databases, the following are the concepts which are common to all databases.
Connection — To work with the data in a database, the first obvious step is the connection. The connection to a database normally consists of the below-mentioned parameters. Database name or Data Source — The first important parameter is the database name to which the connection needs to be established.
Each connection can only work with one database at a time. Credentials — The next important aspect is the username and password which needs to be used to establish a connection to the database. It ensures that the username and password have the necessary privileges to connect to the database. Optional parameters - For each database type, you can specify optional parameters to provide more information on how.
For example, one can specify a parameter for how long the connection should stay active. If no operation is performed for a specific period of time, then the parameter would determine if the connection has to be closed.
Selecting data from the database — Once the connection has been established, the next important aspect is to fetch the data from the database. C can execute 'SQL' select command against the database. The 'SQL' statement can be used to fetch data from a specific table in the database.
Inserting data into the database — C can also be used to insert records into the database. Values can be specified in C for each row that needs to be inserted into the database.
Types of databases and DBMS (with examples)
Updating data into the database — C can also be used to update existing records into the database.A database server is a server which uses a database application that provides database services to other computer programs or to computersas defined by the client—server model.
SQLite are meant for using as an embedded database. In a master-slave model, database master servers are central and primary locations of data while database slave servers are synchronized backups of the master acting as proxies. Most database applications respond to a query language. Each database understands its query language and converts each submitted query to server-readable form and executes it to retrieve results. Every server uses its own query logic and structure.
For clarification, a database server is simply a server that maintains services related to clients via database applications.
The foundations for modeling large sets of data were first introduced by Charles Bachman in DSDs provided a means to represent the relationships between different data entities. InCodd introduced the concept that users of a database should be ignorant of the "inner workings" of the database. Inthe Database Task Report Group of CODASYL the driving force behind the development of the programming language COBOL first proposed a "data description language for describing a database, a data description language for describing that part of the data base known to a program, and a data manipulation language.
In Bachman demonstrated how the relational model and the data structure set were similar and "congruent" ways of structuring data while working for the Honeywell. Chen was able to propose a model that was superior to the navigational model and was more applicable to the "real world" than the relational model proposed by Codd.
