SQL

being stored. SQL Injection It is a common practice in web applications to allow users to enter information into web forms. This user input, unfortunately, opens up the possibility of SQL injection. SQL injection is the most common and well known web application vulnerability. SQL injections can happen when SQL statements are dynamically created when processing user input. It is not difficult for a malicious user to enter SQL directly into the input fields to dynamically change the SQL statement in

discuss the advantages and disadvantages of non-relational databases and the reason companies in the past decade are selecting to implement these databases over traditional relational databases. Keywords – NoSQL, non-relational databases, Not Only SQL, Big Data, Schema-less structure, INTRODUCTION Though non-relational databases have been around since the 1960s, many companies have used relational databases to store data[2] but over the past decade with companies generating vast amounts of

Five Database Trends That Will Take the Spotlight This Year There’s no getting around the fact that we are in the data age. Data is coming at us from all directions, and in all sorts of shapes and sizes. As technology leaders, we’re tasked with answering complex questions like: How are we going to process all this information? How can we make it more accessible? And how will we benefit from it? To further complicate things, new technologies and trends are coming out of the woodwork everyday. Hundreds

Microsoft SQL A Microsoft SQL server is an engine/product, created by Microsoft, to store and accomplish information. SQL server is also known as a Relation Database Management System (RDBMS) in which a set of programming extensions from Sybase and Microsoft add numerous descriptions to standard SQL. SQL Server 2000 has many features from importing, transforming and exporting data from various sources that include Oracle to text files. Advantages There are many advantages of Microsoft SQL. Below are

SQLite is an Open Source database. SQLite supports standard relational database features like SQL syntax, transactions and prepared statements. The database requires limited memory at runtime (approx. 250 KByte) which makes it a good candidate from being embedded into other runtimes. SQLite supports the data types TEXT (similar to String in Java), INTEGER (similar to long in Java) and REAL (similar to double in Java). All other types must be converted into one of these fields before getting saved

NoSQL is the generalized term to describe a relational database that uses no form of SQL language querying and consists of several data models to define it. My topic of this research paper is the Document Store data model. I will be covering the introduction of the model and its mechanics, how and when the model emerged, its strengths and weaknesses, and it’s real world applications. Introduction and How it Works Document Store or “Document-oriented database” is a data model within the NoSQL family

specific_users; / SQL INJECTION The user can influence the SQL code, this is usually as a result of the developer not properly using the right code. The user with some knowledge of SQL will like to put in some values in the form to try and query a database, this might select information from APEX application item, find items, and learn about the application and then can hack the app easily, or execute any DDL command that will alter the database objects. Situation where the SQL statement is concatenated

Big data are grooming in reality. SQL does not have capacity to handle a very huge amount of data. All applications are now working in view to a vast volume of data. Data is increasing massively in almost all stream of jobs , let it be employee details or health records. So the applications being used to manage these type of data should be modified too. Not only the applications but the databases and warehouses where we store these data have to be modifies too. SQL can store data in different tables

Times have changed in the information technology world since 1970 when IBM was running the show and leading the world with improving and introducing new technology. I believe the top five most used RDBMS used in the market today are Oracle, Microsoft SQL server, IBM DB2, MySQL and PostgreSQL. Oracle database had its first

HDFS. Hive was designed to appeal to a community comfortable with SQL. Hive uses an SQL like language known as HIVEQL. Its philosophy is that we don’t need yet another scripting language. Hive supports maps and reduced transform scripts in the language of the user’s choice which can be embedded with SQL. Hive is widely used in Facebook, with analyst comfortable with SQL as well as data miners programming in Python. Supporting SQL syntax also means that it is possible to integrate with existing tools
