Description about the database:-
Deductive database systems are database management systems which are basically designed around a logical model of data. In this type of database systems deductions are made based on the rules and facts stored in the database. We use a language called Datalog which are typically used to specify facts,rules and queries in database. Deductive Database is an advanced form of relational database. When we compare deductive database with relational database we can find that deductive database is more expressive than relational database but, when it is compared to logic programming system it is less expressive. These type of databases use many of the concepts which are specified in logic programming; rules and facts specified in the deductive database language. Deductive database have the additional feature of storing rules that enable inferences based on the stored data to be made. The explicit information is stored in the same manner as that of a relational database. So, deductive are mainly useful and more capable of storing large amounts of information and also perform reasoning based on the acquired information. Deductive has an additional i.e. it is declarative too. Instead of showing how to perform the operation it allows the user to query or update by saying what he or she wants.
Database Management Systems supporting Deductive Database
One of the Database Management Systems that uses deductive database is:- SQUALID. The SQUALID database management system uses squalid query language. This is an extension to SQL query language. The reason for this extension is SQL query language is not efficient enough from deductive point of view and lacks the capacity to manipulate/create rules.For this purpose...

Natural language parsing system AMOS uses Deductive Database LOLA. With the help of SQL interface automatic access is provided to external relational database system by LOLA.
Apart from these it is also used in
• Artificial Intelligence
• Semantic networks
• Frames
• Production systems
• Rules for capturing domain-specific knowledge
Market share of deductive databases:
Market share of these databases is not very high. The reason for it is this type of database is a bit complicated to implement. Most of the market share is being occupied by MySql database making it the most popular database with approximately more than 65000 downloads per day. The use of Deductive database is very limited till now so it is unable to occupy any huge market share. Still new advances need to be embodied to make it a successful database system.
Deductive reasoning is a logical way to increase the set of facts that are assumed to be true. The purpose of Deductive reasoning is to end up at a logical conclusion based on the subject of discussion. Deductive Reasoning uses statements that are logically true in order to omit other statements that contradict the logically true statement, which is to deduce, subtract or takeaway. What
This type of deductive reasoning is extensively used in the field of medicine, in the diagnosis and

Some faculties and departments are already using Oracle applications in their day-to-day operations. As time goes by, more and more information users will be working with an application based on Oracle database technology. If you get the opportunity to be a member of an application development team, you will become familiar with the workings of Oracle and relational databases. Other users may have to learn about this popular database management system through their own experience. This article is for our readers who, as of yet, have no access to Oracle databases but have a yearning for learning what they're all about.
The business intelligence (BI) marketplace is teaming with new innovations and struggles for market share. With new technologies and more companies entering the business intelligence landscape pricing for BI processes and tools are decreasing. “The relational database market is around 30 years old. It should be mature by now, but every year there seem to be new innovations in the relational database space. I’m always astounded that there continue to be new entrants” (Beckerle, p. 281, 2008).
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.
In this iteration, the researcher also learns Structured Query Language (SQL) which is the underlying language used long with JDBC API to get things done in backend (a term used to refer database).
Reasoning can be defined as the problems that differ from other kinds of problems in that they often owe their origins to formal systems of logic (Eysenck and Keane (2005). Deductive reasoning is a type of reasoning that leads to conclusions that are definitely true given that statements the conclusion is based on are true.
The sole purpose of existence of such databases is approach to simplicity in design, better horizontal scaling and greater control over the availability of data. See Figure 3 for scaling. The use of other means of storing data and different access mechanism, provide faster access to data based on the problem which the organization aims and this is also the reason NoSQL databases is famous for use in big-data and real-time web applications.
A data warehouse comprised of disparate data sources enables the “single version of truth” through shared data repositories and standards and also provides access to the data that will expand frequency and depth of data analysis. Due to these reasons, data warehouse is the foundation for business intelligence.
Deductive reasoning is general information people have and use to reach to some type of conclusion. Deductive is done by understanding the first part which is using logic to reach a conclusion which reasoning is to understand what is going on. There are many different ways to explain what is required of deductive reasoning. For example, in an article, it states, “logical way of reaching a conclusion based on ded...
First, database management systems can be very complex and difficult to understand. The designers and the end users must have the necessary skills in order for them to use it properly. The database designers need to have the SQL coding knowledge to properly write the database software. Not only do they have to know SQL coding, they will have to learn the altered version of SQL the database management software might use. The end user will need the understanding of how to run queries, generate reports, and update the database if their security level allows.

In the information age, a lot of data is generated from everywhere. Together with the incoming of information technology tools, so all the data are collected and waiting to be converted to information and knowledge. Therefore, the information industry provides useful information to many areas such as market analysis, science, decision-making and customer relationship. Data mining is the integration between analytical techniques and database system. Previously, it has only database query, data processing or transactional processing, which is insufficient for users to understand the whole data at a time. They cannot answer complex questions such as what are the relationships among items in database. The answers of those questions are more valuable for people. The users need is far exceed database management system ability because of a huge amount of data, so hidden patterns and knowledge should be discovered. Unfortunately, a human ability is limited and people cannot understand a very big dataset by themselves. Thus, the powerful tools are invented to help people to analyze large data. If there are no powerful tools then the huge amounts of data is just pieces of garbage because nobody would like to investigate them. In order to discover hidden patterns or useful information from tremendous data there is a process called “Data mining”.
The Database Management System (DBMS) is software that enables the users to define, create, maintain and control the access to the database. It is a software that interact with the user’s applications programs and it database. Meanwhile, information retrieval system is a system that involved the activity that the systems obtain the information. The obtaining information action need the information from it resources.
