As a result, InfoPump is installed at about 300 customer sites worldwide, whereas PowerMart claims just 60 customers in its first year. rHowever, since the marketplace is beginning to demand an easy-to-use tool in this market space, PowerMart is gaining market

One item of note is that Informaticas first customer was Microsoft. rPlatinum has been in the server-based ETL business since acquiring Trinzic and much of its development team in 1994. Informatica has only been in business since 1996 but

(another ETL vendor) and Sybase employees among its development team. rPlatinum has an alleged and yet unconfirmed alliance with Microsoft in the development of its next generation of InfoPump, due in 1998. Microsoft is also alleged to be using Platinums

This is also unconfirmed. rInformatica has created a metadata specification called MX (Metadata Exchange), which allows end user tool vendors to integrate PowerMarts metadata with theirs. Among the vendors which have made
