Development of Databases and Database Management

Posted on by blogger

The development of databases and database management software is the foundation of modern methods of managing organizational data. The database management approach consolidates data records and objects into databases that can be accessed by different application programs. In addition, an important software package called a database management system (DBMS) serves as a software interface between users and databases. This helps users easily access the records in a database. Thus, database management involves the use of database management software to control how databases are created, interrogated, and maintained to provide information needed by end users and their organizations. Thus, the database management approach involves three basic activities.
1. Updating and maintaining common databases to reflect new business transactions and other events requiring changes to an organization’s record.
2. Providing information needed for each end user’s application by using application programs that share the data in common databases. This sharing of data is supported by the common software interface provided by a database management system package. Thus, end users and programmers do not have to know where or how data is physically stored.

3. Provide an inquiry/response and reporting capability through a DBMS package so that end users can easily interrogate databases, generate reports, and receive quick response to their unplanned requests for information.

A database management system (DBMS) is a set of computer programs that controls the creation, maintenance, and the use of the databases of an organization and its end users. The four major uses of DBMS are;
Database Development:
Database management package like Ms. Access and Lotus allow end users to easily develop the databases they need. However, large organizations with client/ server or mainframe based systems usually place control of enterprise wide database development in the hands of database administrators (DBAs) and other database specialists. Database developers use the data definition language (DDL) in the database management system like Oracle 8 to develop and specify the data contents, relationships, and structure of each database, and to modify these database specifications when necessary. Such information is stored in a database of data definitions and data specifications called a data dictionary (a computer based catalog or directory containing metadata, that is data about data. It includes software components to manage a database of data definitions, that is metadata about the structure, data elements, and other characteristics of an organization’s databases.), which is maintained by DBA.

Database Interrogation:
The database interrogation capability is a major benefit of a database management system. End users can use a DBMS by asking for information from a database using a query language or a report generator. They can receive an immediate response in the form of video displays or printed reports. No difficult programming is required. The query language features lets the user to easily obtain immediate response to ad hoc (unplanned) data requests. The report generator feature allows die user to quickly specify a report format for information he wants presented as a report.
SQL or Structured Query Language is a query language found in many
database management packages. The basic form of an SQL query is; SELECT..
FROM…WHERE…
After SELECT the user lists the data fields he wants, retrieved. After FROM the user lists the files or tables from which the data must be retrieved. After WHERE he specifies conditions that limit the search to only those, data records in which he is interested.
Another query language in some database management package is QBE, or Query By Example. QBE’s point-and-click capabilities make it easier for end users than SQL.
Database Maintenance:
The database of an organization need to be updated continually reflect new business transactions and other events. Other miscellaneous changes must also be made to ensure accuracy of the data in the database. This database maintenance process is accomplished by transaction processing programs and other end user application packages, with the support of DBMS. End users and information specialists can also employ various utilities provided by a DBMS for database maintenance.
Application Development:
DBMS packages play a major role in application development. Application developers can use the internal 4GL programming language and built-in software development tools provided by many DBMS packages i develop custom application programs. For example, a user can use a DBMS easily develop the data entry screens, forms, reports, or web pages of a business application, DBMS also makes the job of application programmers easier. they do not have to develop detailed data-handling procedure using conventional programming language every time they write a program. Ir. they can include data manipulation language (DML) statements in their programs that call on the DBMS to perform necessary data-handling activities.

The Difference between Debt Management Companies and Credit Counseling The Credit Counseling Persp

Posted on by blogger

As consumers struggle to pay for necessities like food, housing, gas, and electricity, they often are faced with deciding between paying for those necessities and paying their monthly payments for credit – based debt. In some cases, consumers are paying only the minimum payments on their credit cards and other installment debt, and in other cases, consumers are making late payments. In the worst case scenarios, consumers are making no payments at all. Faced with extreme measures like bankruptcy, many consumers are turning to debt management companies for help reducing or eliminating their debt.

If you are a consumer struggling to manage your debt, you may be wondering what your options are in terms of debt management and / or counseling. Debt management and credit counseling are not the same, so to make a decision as to which is right for you, you will need to understand what each process entails.

Consumer Credit Counseling

Consumer credit counseling is a process designed to help consumers understand why they are in debt, help them get out of debt, and help them stay out of debt. This process, according to many financial experts, is the best way to manage debt because consumers leave the process with a better chance of staying out of debt than they would if their goal was only to eliminate debt.

Consumer credit counseling takes a lot of effort on the part of the consumer, and understandably so. With an end goal of teaching the consumer what is involved in proper money management, consumer credit counseling is as much about insight, education, and responsibility as it is about reducing and eliminating debt. Although the consumer may be focused on getting out of debt, the process of consumer credit counseling may produce better financial consumers.

In general, consumers who seek out the services of a professional credit counselor is a consumer dedicated to a financial future free of debt. To begin the process, most credit counselors require that the consumer complete a detailed questionnaire that includes detailing spending habits, overall sources of debt, and income. Either over the phone or at an in-person appointment, the credit counselor then works with the consumer to develop a plan to become debt free.

In some cases, consumer credit counselors will require that, as part of the debt elimination / reduction process, the consumer commit a certain percentage of his or her income to pay existing credit – based debts. This percentage is typically based on what other obligations the consumer has such as the need to provide for family members and make other payment obligations. In other cases, the consumer credit counseling process is based on the amount of expendable income that the consumer can work into his or her budget.

In nearly all cases, consumer credit counseling involves teaching the consumer how to manage money. This occurs by examining all expenditures and ranking those expenditures in terms of their necessity. For instance, during the credit counseling period during which the consumer has committed to becoming debt free, a counselor may require that the consumer eliminate all unnecessary spending. After all, in many cases, it is such unnecessary spending that has resulted in a pile up of debt. Consumers, even those faced with rising debt, often continue to spend money on eating out, going to the theater, travel, and other non-essential spending. Consumers who commit to a debt reduction or elimination program through the consumer credit counseling process must also commit to cut all non-essential spending. Once the goal of eliminating and / or reducing all debt has been achieved, the counselor works with the consumer to develop a budget that makes sense

One of the primary differences between the services provided by debt management companies and consumer credit counselors is that consumer credit counselors challenge consumers to make hard choices about how they spend their money and how committed they are to becoming debt free. Consumers who are not prepared to make those hard choices may not be good candidates for a consumer credit counseling program. Other choices for those consumers may be debt management companies, self-management of the debt reduction process, and even, in extreme cases, bankruptcy.

Green Data Centers – Ecofriendly Data Management

Posted on by blogger

No matter which part of the word we talk about, computers have become a way of life for most of us. Adding to this, globalization of internet services has made it inevitable for businesses to maintain a notable web presence. Almost every company uses computers to facilitate its functions and improve its products and services. Considering the reliance we have on computers, it becomes safe to say that the need for efficient data management solutions is here to stay. When it comes to high performance data storage solutions, not every company can afford to have them in-house. Keeping this in mind, facilities dedicated to housing and leasing data storage solutions called data centers came into existence. However, due to the high emission level of these power hungry data warehouses, they have always been a threat to our planet’s ecological balance. To address these issues, Telecommunications Industry Association or TIA for short (the body governing data center architecture) revised the architectural norms of these data centers.

Data centers built under the revised norms are referred to as green data centers as they are much more ecofriendly than their traditional counterparts. While retaining old features such as redundant power and cooling, round the clock technical help, and highly secure data storage environment, the guidelines for the architecture of green data centers also require the providers to use lead free construction material, catalytic converters on power generators, solar panels for reducing dependence on conventional power generation methods and ecofriendly cooling system.

When looking for a data center provider, you must ensure that the data center you choose is built as per the new guidelines prescribed by TIA. Opting for traditional data center would do nothing but increase your company’s carbon footprints and contribute towards hampering the ecological balance of our dear planet. Furthermore, due to green data centers relatively newer than their traditional counterparts, chances are that you will find superior data storage solutions at these newer facilities.

If you think it is your duty to save the planet from the atrocities of rising pollution, you can easily find a suitable green data center provider using any web search engine. However, before you close a deal, always consider factors such as the facility’s record uptime, vulnerability of the area to natural calamities and their past record. To help you make up your mind, it is recommended to go through reviews written by viable providers’ existing clients.
