Some important database applications in the telecom and financial services markets require very fast response from the database system, often measured in millionths of a second. For example, every mobile network has an underlying database that tracks the current location of every mobile phone and of the particular cell tower that is servicing the phone. This database must always be up to date so the network can determine at all times where to route an incoming call for any mobile phone that is connected. If a call is already under way and the mobile user is on the move (for example, if he or she is riding in a car), the database demands are even higher, because the call in process must be handed off from one cell location to another. For a network of tens of millions of mobile phones, each individual database access must be very short, or the database will become a bottleneck to call processing.

The database demands are even higher if the mobile user is on a prepaid billing plan. When such a customer tries to use a mobile service to make a call, send a text message, or access the Internet the network must quickly determine whether to allow the action. Behind the scenes, software in the network must determine which customer is trying to act, find that customer s billing plan, figure out the billing charge associated with the action (which may vary depending on the time of day or the location, or on whether the customer is being called or texted, or on many other factors), look up the customer s current account balance, determine whether the customer has sufficient funds, and deduct the initial charges from the customer s balance. This sequence can require dozens of accesses and updates to the operator s billing database all while the customer and the network are waiting for a call or some other activity to start. In many areas of the world, a mobile network will have tens of millions of subscribers, the vast majority of whom are prepaid customers, so again database access must be very swift. Financial trading applications pose a similar database latency challenge. Feeds of market data, such as offers to buy and sell stocks, can exceed 50,000 messages per second, and that total is revised upward at least twice a year. A computerized stock trading application that tracks the current state of the total market must be able to process each message (usually requiring an update of a database row) in less than 20 millionths of a second, or it will fall behind the incoming messages. In addition, the ability to trade quickly as market conditions change is a key competitive advantage in stock trading, so shaving even a few millionths of a second from database delays can be worth millions of dollars per year. The demands of applications like these are beyond the scope of mainstream database systems today. In the typical client/server architecture, the delay associated with the network alone is often measured in milliseconds (thousandths of a second), so even an infinitely fast database poses too much delay. If the network delay is eliminated, access to the physical disk where the database is stored can take tens of milliseconds, shifting the bottleneck to the computer s storage. Even if this delay is eliminated, the complexity of the database software and the number of CPU instructions that it must process for even the simplest of database operations can add up to tenths of a millisecond or more. To meet these extreme demands, developers historically built proprietary homegrown databases, customized to the specific requirements of each application. Every major Wall Street brokerage firm had an IT department that built its own trading database system, and every major telecom equipment vendor built one or more network databases to support its network equipment. In the late 1990s, a new breed of standard database software emerged to address these requirements the SQL-based in-memory database.
