Project:End of Day Store (EODS)
End of Day Store (EODS) is a data store which stores and exposes Accounts, Balances, Positions and Activity information for BETA Brokerage and Annuities. The data is updated once in a day during non peak hours and is consumed 24/7 by applications - like OST/CV, MyFA, SSD and Financial Planning apps. At a high level, data flows from BETA through Brokerage Mainframe into EODS and is exposed to the consumers through stored procedures and Web services. EODS batch is scheduled in TWS and it will load into TWS for the batch cycle.
