This suite consists of six EJB components which perform calculations related to simple and compound interest. In particular, methods are developed for calculating the accumulated value, present value and yield of an interest bearing investment.

What's New

We included laws for the manipulation of exponents and formulae for the sum arithmetic and geometric series. These formulae form the basis of the mathematics related to interest calculations. Using these classes developers can more easily implement new formulae and modify our formulae according to there exact needs.

New Features: Self-Deploy, EAR Files

By clicking the self-install package the EJB component will be automatically deployed onto a supported local EJB application server. We also include multiple EAR files designed for each of the most widely used application servers (see details).

Product Details

This suite allows us to calculate the following quantities:

• Exponents and Series
  • Law of Exponents - the laws which define and allow for the manipulation of exponents
  • Arithmetic Progression - formulae for the sum of an arithmetic progression
  • Finite Geometric Series - formulae for the sum of a finite number of terms of a geometric progression
  • Infinite Geometric Series - formulae for the sum on convergent infinite geometric series
• Simple interest
  • Simple interest - a deposits value after a single period in which the interest accumulates
  • Real worth - the accumulated value taking into account the rate of inflation
  • Real return - the effective rate of return taking inflation into account
• Compound interest
  • Accumulated values - the accumulated value after a given number of periods for a fixed interest rate
  • Real worth - the worth of an interest bearing investment after p periods of time according to the Euro, UK and Japanese conventions on interest payments
  • Real return - the return from an interest bearing investment taking into account inflation over p periods of time according to the Euro, UK and Japanese conventions on interest payments
  • Depreciation - calculates the percentage decrease in the book value of assets over one time period or many time periods with differing rates of decreasing book value
• Effective and nominal interest
  • Effective rate of interest - converts the effective p-yearly rate into the effective q-yearly rate
  • Real return - converts between the q-yearly and p-yearly rates of interest taking into account the rate of inflation
  • Force of interest - the total sum when the interest is compounded continuously over t periods
  • Nominal rate of interest - converts between the effective rate of interest and the nominal rate of interest convertible p-yearly
• Accumulated values of annuity-certain
  • Accumulated annuity certain in arrears - series of payments of one per interval payable in areas for n intervals
  • Accumulated annuity certain in advance - series of payments of one per interval payable in advance for n intervals
• Present values
  • Present value - find the initial investment which needs to be invested in order to achieve a final sum in absolute or real terms
• Present value of annuity-certain
  • series of payments of one per interval payable in areas for n intervals
  • series of payments of one per interval payable in advance for n intervals
  • infinite series of payments made at the end of each interval
  • an increasing annuity in which the first payment is one after one interval, the second payment is two after two intervals and so on... with a final payment of n after n intervals
  • series of payments of one per interval payable p times per interval in areas for n intervals
  • series of payments of one per interval payable p times per interval in advance for one interval
• Yield
  • Internal rate - calculation of the internal rate of yield, or the interest rate required to generate a given yield
  • Real and nominal - conversion between real and nominal yields given the annual rate
• Real returns
  • Bonds - the present value of a bond paying a coupon p over n periods, assuming that the inflation is constant
  • Real return - the rate of return on an investment over a period given the initial cost, total payment, and inflation rate

This package also contains the following features:

• GUI Bundle - we bundle a suite of graphical user unterface JavaBean components (with a site-wide licence) allowing the developer to plug-in a wide range of GUI functionality (including charts/graphs) into their client applications.
• EAR Files - we provide individual customized EAR files for the most widely used application servers including IBM WebSphere 4.0/5.0, BEA WebLogic 6.1/7.0, Oracle 9iAS, Sun ONE AppServer 7, Ironflare Orion 1.5.2/1.6.0, Borland AppServer 5.0, Sybase EAServer 3.6 and JBoss 2.4.4/3.0.0
• Self-Deploy - the relevant servers EAR file will be self-deployed onto supported local application servers during the installation of the self-install package. The supported application servers include IBM WebSphere 4.0/5.0Beta, BEA WebLogic 6.1/7.0, Oracle 9iAS, Borland AppServer 5.0, Ironflare Orion 1.5.2/1.6.0 and JBoss 2.4.4/3.0.0
• Synthetic JDBC - we use a JSP component to perform EJB calculations on SQL database columns from a remote DBMS. We apply an EJB function to certain rows from the database and list the output in HTML format. This is a powerful feature since it allows you to perform calculations in a JDBC manner without having to hardcode the EJB-to-JDBC transaction yourself as it is all done by the JSP within the Application Server
• JDBC Mediator - An server side EJB component which mediates between a EJB component, clients and DBMS. The mediator moves most of a clients JDBC calls to the server and hence greatly increases the speed of JDBC client applications
• UML Models - to assist software architects we include UML diagrams
