An Introduction To Postgresql Monitoring And Statistics

Relational database systems came into existence in the 1970’s, and revolutionized the way data is maintained in computers. Like every technology that is subjected to test of time, relational database systems are under criticism for not being scalable enough to meet growing users and exponentially increasing data management needs. Today, a new technology called NoSQL is being pioneered by leading companies like Google, Amazon, and Facebook etc. to meet the shortcomings of the 40-year-old relational database technology. Modern web applications are making a transition from traditional relational databases to NoSQL databases to meet the demand of steadily growing concurrent users and big data.

Data is ever increasing. We need a system to represent, store and manipulate complex information, detect correlations and patterns, construct data models etc. Furthermore, being independently maintained, data can change in time or even change its base structure, making it difficult for modelling systems to accommodate these changes. Current representation and storage systems are not very flexible in dealing with structural changes and also they are not powered with the ability of performing complex data manipulations of the sort mentioned above.

Cloud computing has really shifted the whole landscape of how companies do their databases now, and with this has brought the concept of big data.

Data and information management is a huge growth area. But it's not just data management creating new job opportunities, its gathering, analyzing, storing and securing the data as well.

Most database ensure that they follow the ACID (Atomicity, Consistency, Isolation, Durability) properties to ensure the transactions are reliable. The studies show that stores that guarantee ACID property generally have poor availability. As a result, Dynamo focusses on application that have weaker consistency.

Operating system software provides a platform for computerized Big Data management. Computerized systems running on operating systems are used in data collection, storage, and analytics, thus making the process more accurate, efficient, and reliable.

This is one of the greatest challenge that is acting as a key barrier in widespread adoption and pervasive use of the tools fostering for development and progress in this field of study. The real time of the big data analytics would require some of the unique features and special computing powers and potentials (Gantz, 2012). Tools have to made specially advanced so as to incorporate process terms in real time (Chen, 2012). Every business oriented organization should be transformed into information centric (Kaisler, 2013) to focus upon the real time data analysis in terms of both input and output.

Results-based monitoring and evaluation is a set of concepts associated with performance management or results based management (RBM) strategy, which evolved in 1990’s. During that period, many countries introduced extensive management reforms in responding social, political and economic pressures that were triggered by the factors of globalisation, budget deficits, structural adjustments and competitiveness (Binnendijk, 2000). Central feature to most of those reforms has been an emphasis on ‘performance improvement’ and ‘achievement of targeted/expected results’ which were the core features of RBM. RBM has been used by many development agencies, governments, and donor agencies in delivering development interventions and has become an emerging trend in contemporary development practice.

Mission critical databases support services that have an immediate, direct, and significant impact on revenue, goodwill, health and safety, and regulatory compliance. They require more attention than other systems. I will be discussing the following topics in this paper

Today, the world’s trend in operating business focuses on data availability to enact the best suitable decision to improve, develop, and increase business revenues. Moreover, the availability of data helps to monitor and control the quality of provided products or services. However, the availability of data without proper analytics operations would have no meaning (1). Data analytics provide an important aid to an organization to figure out their position in the market in comparison with their competitors. Also, data analytics helps to identify what is the organization’s competitive ability in the market, what they should bet on, and what they should strive for. With that being said, many of today’s most successful organizations utilize

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 data, relational databases are unable to effectively manage these large data collections[1]. An ever increasing amount of companies is now, however, turning to non-relational databases known as NoSQL databases as they are more effective at handling these large amounts of data thus the reason we have seen an increase in its popularity over the past decade[2]. The term NoSQL database which stands for Not Only SQL[3] is defined as a database that

Epiviz is a computational and visual data analysis for genomics; workflows that involve the integration and exploration of multiple heterogeneous data sources, small and large, public and user specific have been poorly addressed by these tools. Epiviz wants to fix that and make it simpler for scientists to use for their own research on studying genomes. The general concept of the research project is to push more of the data analysis supporting interactive visualization to the backend. The system will display visualization resource constrained data transformations and different visualizations that the data scaling will support include scatter plots, heat maps, stacked bar charts and other graphics to help clients organize data.

Today, data is a growing asset that various businesses are having difficulty converting into a powerful strategic tool. Companies need help turning this data into valuable insight, which can diminish risk and enhance returns on investments. Companies are struggling to make sense and obtain value from their big data. Superior and reliable

pooled data. Splunk central receiver receives variety of data from many different ports and displays them as events on a single server. From one place, one can be able to access the log files in any of the web servers of the business, all the databases, routers, load balancers, and firewalls from all the companies’ operating systems. All the logs and configuration files can be accessed and analyzed, as well all from one device.

Data has always been analyzed within companies and used to help benefit the future of businesses. However, the evolution of how the data stored, combined, analyzed and used to predict the pattern and tendencies of consumers has evolved as technology has seen numerous advancements throughout the past century. In the 1900s databases began as “computer hard disks” and in 1965, after many other discoveries including voice recognition, “the US Government plans the world’s first data center to store 742 million tax returns and 175 million sets of fingerprints on magnetic tape.” The evolution of data and how it evolved into forming large databases continues in 1991 when the internet began to pop up and “digital storage became more cost effective than paper. And with the constant increase of the data supplied digitally, Hadoop was created in 2005 and from that point forward there was “14.7 Exabytes of new information are produced this year" and this number is rapidly increasing with a lot of mobile devices the people in our society have today (Marr). The evolution of the internet and then the expansion of the number of mobile devices society has access to today led data to evolve and companies now need large central Database management systems in order to run an efficient and a successful business.
