The reason for the selection of this topic is because it falls under the computer science category. We have been studying databases for four years and so the this topic area will be of great use when venturing into the cooperate world.
Knowledge gained will assist in tackling real life situations when it comes to real-time database transactions. Diagnosing problems related to the topic area will prove slightly easier.
Real-time databases are being utilized within the manufacturing for the benefits associated with the these databases compared to conversional ones.
Despite the benefits, there are challenges that may arise as a result of using them, transaction processing is one of the problems areas
Overloading is the result of an overload is a slow response throughout the duration of the overload) .
Dealing with overloads is complex ,practical solutions are required to tackle this issue.
The focus of this presentation will be centred on overload management issues within real-time databases for manufacturing.
Real-time database systems are prone to overloads from time to time.
Service requests exceed available resources for a limited time resulting in missed deadlines. may occur when faults in the computational environment reduce computational resource available to the system. may occur when emergencies arise which require computational resources beyond the capacity of the system.
Overloads cause performance degradation
Schedulers are usually not overload tolerant.
Resource management comprises of two components: scheduling and admission control.
Scheduling determines the execution order of admitted transactions ,Ali and Gulhane (2014) state that scheduling is based on t...

...transactional Multimode Model is a better method of dealing with transactional overloads. This protocol adapts its behaviour to overload situations which cannot be handled by importance protocols
In this paper we discuss
PERFORMANCE ISSUES
Allocation or resources service requests exceed available resources when faults in the computational environment
SOLUTION
Use of parameters to select important transactions from less important ones

...ion in real-time is possible, since applications with the back office ERP System are integrated. So, the time integration is a trivial issue. Some authors confirm that if support processes apply this form of integration, it would not have negative impacts on any of the critical factors in the industry [13].
The common element of the open source databases is the use of share data of student information. The common features used by the databases are their operating systems UNIX or Windows, as well as MYSQL database. The database used b...
Unknown / unintentional or un-covenanted movements this could be in the form of unpredictable movements whilst the equipment is being maintained or at the reinstatement of power. Other causes may be due to the corruption of software, or damage to the any of the peripherals or programmable electronics.
There are customer tools and transaction processing, network applications and database so that transaction of data is reliable and secure.
System performance is one of the most critical issues faced by companies dealing with vast amounts of data. Companies use database systems and their applications to store, retrieve and handle this data.

Database is hart of every application and to keep it running 24*7 monitoring is required, DBA team has to support this Monitoring and handle issues occurred during this time, Majority of organization divide DBA team in to 3-4 teams to support different application, all the details with timing are shared with application and whenever required they reach out to available DBA for that time frame.
Databases are becoming as common in the workplace as the stapler. Businesses use databases to keep track of payroll, vacations, inventory, and a multitude of other taske of which are to vast to mention here. Basically businesses use databases anytime a large amount of data must be stored in such a manor that it can easily be searched, categorized and recalled in different means that can be easily read and understood by the end user. Databases are used extensively where I work. In fact, since Hyperion Solutions is a database and financial intelligence software developing company we produce one. To keep the material within scope I shall narrow the use of databases down to what we use just in the Orlando office of Hyperion Solutions alone.

It simplifies the storage and processing of large amounts of data, eases the deployment and operation of large-scale global products and services, and automates much of the administration of large-scale clusters of computers.
Oracle's relational databases represent a new and exciting database technology and philosophy on campus. As the Oracle development projects continue to impact on University applications, more and more users will realize the power and capabilities of relational database technology.
In the past, most of the databases were centralized, protected, and kept in a one location using a complicated database system known as centralized database. Nowadays, with the new technology of personal computers and cell phones, a new sort of database has appeared, and it seems that majority of people are pleasant with it, even if their private data is split everywhere. Many enterprises had changed their databases from the centralized databases, into the distributed database system, since it meets the demand of accessing and processing the data in the organization. Distributed database technology is considered as one of the most remarkable developments in this century (Ozsu, 1991; Rahimi & Haug, 2010; Cain, 2012). Distributed databases are basically a collection of databases that are divided on multiple computers which are connected logically but located in different physical locations, and each site manages its own local data. In contrast, centralized database is a database that is located in a one location and it is considered as a big single database (Connolly & Begg, 2010).
A computer is unable to store enough data to answer a wide range of questions by the questioner.
Another function of the DBMS is the concurrency control services. Database Management System must ensure that the database is updated correctly because the database can be used by many multiple users. The DMS enable many user to access the data concurrently. The database managements system will help from ay data loss. It have the features which that can support the updates like batch processing, locking, two-phase locking and the time stamping.
In our world, people rely heavily on the power of technology every day. Kids are learning how to operate an iPad before they can even say their first word. School assignments have become virtual, making it possible to do anywhere in the world. We can receive information from across the world in less than a second with the touch of a button. Technology is a big part of our lives, and without it life just becomes a lot harder. Just like our phones have such an importance to us in our daily lives, database management systems are the same for businesses. Without this important software, it would be almost impossible for companies to complete simple daily tasks with such ease.
