FIG. 12 is a sequence diagram showing the operation of the document management system 11. Description will be made on the assumption that text data and the like are stored in the document information DB 50 in the same procedure as that shown in FIG.
The database access unit 34 of the user terminal 30 acquires the search keyword input by the user via the input unit 32 (S141). The database access unit 34 reads the business ID 36a stored in advance in the storage unit 36, and transmits it to the document management server 40 via the communication unit 35 together with the search keyword (S142). Receiving this, the communication means 46 of the document management server 40 transfers the search keyword to the content distribution server 60 (S143).
The content distribution server 60 searches the content DB 61 using the received search keyword as a key, acquires a title list of content including the keyword that matches the search keyword (S144), and transmits it to the document management server 40 (S145). .
The database access means 45 of the document management server 40 searches the document information DB 60 in the same procedure as that shown in S113 of FIG. 7, and acquires a title list of text data including keywords that match the search keywords (S146). . The database access unit 45 transmits the title list and the title list received from the content distribution server 60 to the user terminal 30 via the communication unit 46 (S147).

The user terminal 30 that has received the title list by the communication means 35 displays it on the output means 33 and presents it to the user. The database access unit 34 acquires the selected title of the content or text data input by the user via the input unit 32 (S148). Here, the description will be made assuming that the title of the content stored in the content DB is selected as the selected title. The database access unit 34 of the user terminal 30 transmits the selected title to the document management server 40 via the communication unit 35 (S149). Receiving this, the communication means 45 of the content distribution server 40 transfers the selected title to the content distribution server 60 (S150).
The content distribution server 60 searches the content DB 61 using the selected title as a search key, acquires the content corresponding to the selected title (S151), and transmits it to the document management server 40 (S152).
The database access unit 45 of the document management server 40 registers the received content in the document information DB (S153), and the communication unit 46 transmits to the user terminal 30 (S154).
The charging processing means 49 adds 1 to the usage count 62c of the record corresponding to the content transmitted from the accounting DB 62 and updates the usage amount 62e with a numerical value obtained by multiplying the updated usage count 62c and the unit price 62d ( S155).

  According to the document management system 11, since the database access means 45 also searches the content registered in the content DB 61, the user is not only the information collected in the user company 1, but also the content providing service provider. The information provided from 6 can also be used.
