We like to think that when we deposit a dollar at the bank, it goes into a big vault and we can pull out that same dollar at any time. But that¿s not how the U.S. banking system works. Banks take that money and invest it to make money themselves, so cash gets spread around. This, naturally, leads to a big risk: What happens if those investments go sour? Well, you¿d be out of luck. You can¿t get your dollar back.
The Federal Reserve doesn¿t like that scenario, so it prohibits banks from putting all the cash it has on deposit on the line. In fact, the Fed forces banks to keep a portion of their assets at the Federal Reserve itself, to make sure that some of your assets won¿t get squandered if the bank¿s bets go south. These are called ¿reserves,¿ (hence, Federal Reserve. Got it? Good), and usually amount to 10% of the total cash kept in checking accounts.
These reserves are never exactly 10%, and banks like to keep a little extra in reserve ¿ not, as you might think, to make you more comfortable that they¿re in good financial shape, but rather so they can take that excess and lend it to other banks and make money off it. (They¿re banks, they can¿t help themselves.) The rate at which they make these loans is called the Federal Funds rate, which is set by the Federal Reserve¿s Federal Open Market Committee.
When you hear people chattering about how the Fed cut or hiked interest rates, this is what they¿re talking about: the interest rate banks can charge for lending money from their reserves. This begs the question: If these are essentially loans between banks, why is the Fed Funds rate so important for the rest of the economy?
Well, simply put, because loans make the financial world go round. Bank A lends Bank B $10,000 at a Fed Funds rate of 5%. Bank B then lends out $10,000 to a small business at 7%. The small business then takes that money and expands the business and hires new workers. Now someone is employed, Bank B has made interest off the loan, and Bank A is the richer for making it all happen. It¿s perhaps overly simplistic, but you get the idea. When you want the economy to thrive, you make lending cheaper.
Of course, sometimes you don¿t want the economy to thrive. In fact, you might want it to cool down, mostly to avoid money flooding the system and causing inflation. In that case, the Fed raises interest rates, making it difficult to lend or borrow.

J9 Technologies Delivers New JDBC Protocol Add-in Solution for HP LoadRunner to Help Customers Streamline Middleware Testing
Comtex
SEATTLE, May 27, 2008 /PRNewswire via COMTEX/ ----J9 Technologies Inc. today announced a new solution in its JDBC Protocol Add-in product line, enabling customers to extend the capabilities of HP LoadRunner, to stress and isolate problems in the backend data tier and deploy new applications with confidence. J9 is a member of the HP Quality Management Ecosystem, which provides alliance members the ability to develop test accelerators for HP Quality Center and HP Performance Center to support additional platforms, applications and environments.
The JDBC Protocol Add-in leverages HP LoadRunner technology, capturing all SQL traffic going from a Java application to the backend database and playing it back to directly exercise the data tier for high concurrency testing. This helps QA teams apply a measurable and repeatable load to the database and expose potential performance problems early in the development cycle. The auto-generation of database testing scripts replaces the need for writing complex Java code and frees up QA resources for other QA activities.
The JDBC Protocol Add-in from J9 Technologies is fully tested with the full suite of HP LoadRunner solutions, and can easily be used alongside all other HP LoadRunner protocols to create a more realistic and comprehensive load test.
"For the last 6 years, J9 Technologies has been working closely with HP to ensure that customers get more out of their HP LoadRunner and HP Performance Center investments," said Clay Roach, President and CEO for J9 Technologies. "We are very excited about this latest addition in our new line of JDBC Protocol Add-ins and the value it will deliver to our mutual customers for simplifying their JDBC testing efforts. The JDBC Protocol Add-in can help reduce testing cycles dramatically and enable QA, Dev and DBA teams to collaborate on fine-tuning database testing."
"HP is committed to helping our customers rapidly deliver critical business applications that function and perform according to the needs of the business," said Erez Barak, director of product marketing, Software, HP. "HP's collaboration with J9 helps our customers increase efficiency by streamlining the complex process of database testing."
JDBC Protocol Add-in is available today, and is compatible with HP LoadRunner and HP Performance Center version 9.1 and up.
