A roundup of business developments spotted by other publications.
Super Library: E-Systems Inc. of Dallas announced its first commercial contract for the development of a database that could store 100 trillion characters of information--four times as much as the Library of Congress. The EMass system, to be built for the exploration unit of Mobil Corp., compresses 200 standard magnetic computer tapes into two high-density tapes and uses robots to retrieve the tapes from shelves. Neither E-Systems nor Mobil disclosed the size of the contract, but the initial phase appears to be worth $5 million. Philip J. Rasch of E-Systems estimated that $2 billion worth of massive storage systems could be sold in this decade. Dallas Morning News
Target Expansion: Positioning itself as the nation's third-largest discount chain, behind K mart and Wal-Mart, Dayton Hudson Corp. of Minneapolis announced that it will double the pace of construction of Target stores, opening 300 outlets in five years. Chairman Kenneth Macke said 80 new Mervyn's stores will also be opened in that period, triple the present rate of seven stores this year. George Rosenbaum of Leo J. Shapiro & Associates, a market research firm in Chicago, called the plan surprisingly small. Target operates 407 stores in 32 states; Mervyn's has 221 stores in 15 states, with 1989 revenues of $7.5 billion and $3.9 billion respectively. St. Paul Pioneer Press
