First time investors whether it’s in currencies, stocks commodities or bonds should make low risk investments by using small amounts of capital.
Nowadays anyone that has a computer and has access to the internet and an online bank account has the ability to trade stocks and currencies almost immediately. This has meant that many investors now don’t have to rely on mutual funds or other money managers to manage their investments for them as they can now trade and manage their own investments. Unfortunately, to be a successful investor there is many pitfalls that first time investors should be wary of.
Six Moves which are Dangerous for First Time Investors:
What is Database?
A database is a collection of organized data, information and records. Whenever you make a list of anything, example, list of groceries to buy, books to borrow from the library, list of classmates, list of relatives, list of friends, telephone directory and so on; you are actually generating a database.
Computer databases are those data or information stored in the computer. To arrange and organize records, computer databases rely on database software.
Database software allows the user to collect, edit, delete and organize information so that they can easily be managed, updated and accessed by the user. Microsoft Access is an example of database software.
Purpose the database
A database is an important document in many people's lives, especially contact numbers of close relatives and friends. Database is information that a person needs in his personal, business, social and religious life and the power and purpose of information is not only in collecting and finding them but more importantly in using them.
Therefore, it is up to the values and circumstances of that person to use that information, and there is one saying to this effect that is, "use it but do not abuse it". When you have the information you can save, print, copy and paste, analyze, transmit and share the database.
Kind of Databases
1. Structured database - It is also called the structured data which a record or file of information is arranged in uniform format. These databases are usually storage of information with similar entries such as a list of persons born in a country, a medical database of patient's data, an inventory database of a company and many others.
2. Free-form database - It is a loose collection of information, such as those you will find on the World Wide Web. A collection of your documents in the computer made from several programs can be considered as free-form database.
Types of Databases
1. Operational database - It is a dynamic database that is used by any organization in its day to day operation. They are used to collect data, maintain, modify and delete data. An example of operational database is the inventory database which constantly changes as the company go about its daily business deals.
2. Analytical database - It is a static database, wherein data is rarely modified. This database is often used to store and track historical data to make long term projections and analysis. An example of an analytical database includes data on global temperature to determine the effects of global warming in certain areas for a period of time.
Structured Database Models
Hierarchical model - this model can be visualized as a parent-child relationship wherein a child may only have one parent but a parent can have several other children. They are tied and linked together by "pointers" wherein parent will have pointers to each child. Another way of looking at this model is by visualizing an inverted tree. The single table acts as the "root" of the inverts tree and the other tables act as branches. To access the data from one of the tables, one has to pass through the root table.
Network model - this model was developed to address in part the problems of the hierarchical model. As with hierarchical model, it could be visualized as an inverted tree, however this model allows many inverted trees sharing branches but are still part of the same database structure. As with the parent-child mode the child is allowed to have multiple parents. Unlike in the hierarchical mode access of data begins from the root table. In the network model, it allows access of data from any table. This model was eventually replaced by the relational database model.
Relational model – The terms relations, attributes and domains are used frequently in relational database models. A relation is a table with columns and rows. Attributes are the name given to each column of the relation. Domain is the value with which the attribute will take. The relational database model starts from a table which contains information about an entity for example, a student.
Relational Database Management System (RDBMS)
A Relational Database Management System (RDBMS) is designed to create, maintain, manipulate, modify and delete information in a relational database. As previously mentioned, modern databases utilize the relational database model and many of today's software caters to this type of structured database.
An RDBMS allows you to do the following:
Create a Database - Personal and business database need to be created and RDBMS programs will help facilitate this process. Database creation is made easier and faster because of these programs. Many of them have templates to choose from so you do not have to start from scratch, however, if needed you can also start you own.
Information Storage - Once your database is created, it is now easy to add information into your database. A database program allows you to add, organized, modify, edit and delete your information as you deemed fit.
Information Retrieval - Since your database is created in a structured fashion, it is easy to retrieve data. In databases, the means to retrieve data is by query. Query is a request for specific information from the created database.
Information management - RDBMS programs allow you to utilize and modify the information database according to your needs.
Information Analysis - The most important function of a database is using it, accumulated and gathered is an asset in this Information Age.
Print and Share Information - For purposes of a "hard copy", information may be printed and as back up copy in case the digital copy of the database gets corn or damaged. Printed information is also necessary for people who are not used to view data in the computer monitor and prefer then on paper.
Qualities of Good Database information
1. Accurate information means the reports generated from the database program are error free. Having inaccurate reports could mean disastrous result for others using the information.
2. Organized information means the reports maybe arranged to suit the need the decision maker. The president of the company may only be interested in the profit or loss while the finance manager may want the details of expenses and cost of goods sold.
3. Timely information means the report should be useful at the moment it is generated.
4. Verifiable information means the report can be proven to be correct or incorrect.
5. Accessible information means the database report is available to the person who needs it at anytime
6. Economical information means information generated from a database program should be cost-effective to product. Generating reports from a database costs money and the means of sharing these to the right people in the organization is crucial in cutting cost to a minimum. Many organizations post reports on the internet for access to people who need them.
7. Useful information means the report should have meaning to the people who get them. Information is important to a lot of people, and some information are only relevant to some.
Relational Database Terminologies
Data - It is a number or value found and stored in the database. Data is static because it remains the same until it is modified by a process.
Information - It is a data that has been processed thereby making it relevant and meaningful to the person viewing it. Information is dynamic because it changes relative to the data stored in the database and it could be processed in many ways.
Null - It is used to represent a value that is unknown or missing. A null value is neither a zero nor blank.
Table It is the main structure in the relational database. It is composed of attributes (fields) and domain (records). A table almost always represents a subject that can be an object (person, place or thing) or an event.
File - It is an organized collection of data about an entity. As an example, for a bookstore, a file called "Branch" can contain all the data about a
particular bookstore branch.
Record - it refers to a specific person, place, thing or event. Record is also known as the "tuple" in the relational database terminology. It | to structure in the database table representing a unique instar subject.
Field - It is the smallest structure of a data from a larger database structure in a relational database. A field can store data in a database represent a character of the subject to which database table it resides.
View - It is also known as a virtual table. It is called a virtual table does not hold data on its own; rather it gets data from the tab it is based.
Keys - These are fields that serve specific purposes within a table.

George Blanda, who played longer than anyone in pro football history and racked up the most points in a career that spanned four decades, mostly with the Chicago Bears and Oakland Raiders, died Monday. He was 83.
''We are deeply saddened by the passing of the great George Blanda,'' the Raiders said Monday in confirming his death. ''George was a brave Raider and a close personal friend of Raiders owner Al Davis.'' The Pro Football Hall of Fame said on its website that Blanda died Monday after a brief illness.
Blanda retired a month shy of his 49th birthday before the 1976 season. He spent 10 seasons with the Bears, part of one with the Baltimore Colts, seven with the Houston Oilers and his final nine with the Raiders.
