Moreover, skilled DBAs are rare and expensive. The tasks that a Database Administrator (DBA) performs can be made autonomic. The autonomic behavior is important in systems, networks, communication as well as database management systems (DBMSs). The need of self-management is realized due to maximum functionality, huge complexity and data structures to process huge data. The purpose of these policies to restrict insider user or Database Administrator (DBA) from malicious activities to protect data.Įvolution of computer starts from human dependent to self-management in order to reduce time and complexity with increase in accuracy, reliability and efficiency. This research proposes an autonomic model for protection that will enforce Access Control policies, Database Auditing policies, Encryption policies, user authentication policies, and database configuration setting policies in DBMS. We offer an autonomous approach to self-protection architecture based on policy implementation in DBMS. To protect and monitor organization information from insider user in DBMS, the organization used different techniques, but these techniques are insufficient to secure their data.

Employees within the organization carry out or harm organization data in a professional manner. Insider threats in database management system (DBMS) are inherently a very hard problem to address. Managing and mitigating these internal or external security related issues, organizations hire highly knowledgeable security expert persons. In today's world, information security of an organization has become a major challenge as well as a critical business issue.

Current issues are highlighted at the end with future directions. The state-of-the-art practices in large-scale data repositories are reviewed with respect to AC for characterization, performance prediction and adaptation of workload. This work presents a taxonomy through systematic analysis of workload management in large-scale data repositories with respect to autonomic computing (AC) including database management systems and data warehouses. Workload management involves effectively monitoring and controlling the workflow of queries in large-scale data repositories. The intelligent system could be designed by knowing the type of workload in advance and predict the performance of workload that could autonomically adapt the changing behavior of workload. Autonomic technology can support predicting the workload type decision support system or online transaction processing can help servers to autonomously adapt to the workloads. This requires computational power for managing the load of current servers. The large volume of data, dynamic behavior and versatility of large-scale data repositories is not easy to be managed by humans. The workload in large-scale data repositories involves concurrent users and contains homogenous and heterogeneous data. A comparison of autonomic components of Oracle with SQL Server is provided to show their autonomic status. We have performed the same type of research over Microsoft SQL Server and DB2. The research is focused to find and earmark those areas in Oracle where the human intervention is required. This analysis illustrates how different components of Oracle manage itself autonomically. The paper explores and analyzes the autonomic components of Oracle by considering autonomic characteristics. The DBMS that has the ability to manage itself according to the environment and resources without any human intervention is known as Autonomic DBMS (ADBMS). With autonomic capabilities administrators can perform higher-level tasks. Autonomic capabilities in Database Management Systems (DBMSs) are also essential for ease of management, cost of maintenance and hide the low level complexities from end users. Databases are growing w.r.t size, functionality, heterogeneity and due to this their manageability needs more attention. Database has become the integral part of information system in most of the organizations.

These capabilities in software and systems increase performance, accuracy, availability and reliability with less or no human intervention (HI). The autonomic capabilities in computers and IT have become the need of the day. Human world is becoming more and more dependent on computers and information technology (IT).
