  Sl.# DBMS RDBMS 1Introduced in 1960s. Introduced in 1970s. 2 During introduction it followed the navigational modes (Navigational DBMS) for data storage and fetching. This model uses relationship between tables using primary keys, foreign keys and indexes. 3 Data fetching is slower for complex and large amount of data. Comparatively faster because of its relational model. 4 Used for applications using small amount of data. Used for huge applications using complex and large amount of data. 5 Data Redundancy is common in this model leading to difficulty in maintaining the data. Keys and indexes are used in the tables to avoid redundancy. 6 Example systems are dBase, Microsoft Acces, LibreOffice Base, FoxPro. Example systems are SQL Server, Oracle , MySQL, MariaDB, SQLite.

  The Evolution ofDatabase • Navigational DBMS • The introduction of the term database coincided with the availability of direct-access storage (disks and drums) from the mid- 1960s onwards. • 1960 • SQL DBMS • he first version was ready in 1974/5, and work then started on multi-table systems in which the data could be split so that all of the data for a record • Late 1970 NoSQL and New SQL • XML databases are mostly used in enterprise database management, where XML is being used as the machine-to- machine data interoperability standard. • 2000 • Relational DBMS • Edgar Codd worked at IBM in San Jose, California • the lack of a "search" facility • 1970 • On the desktop • C. Wayne Ratliff the creator of dBASE stated: "dBASE was different from programs like BASIC, C, FORTRAN, and COBOL in that a lot of the dirty work had already been done.• 1980

  Advantages Market Presence Oracle isby far the largest RDBMS Vendor, and spends more on R&D than most of its competitors . Performance Speed of a *tuned* Oracle database and application is quite good, even with large databases. Multiple Database Support Oracle has a superior ability to manage multiple databases within the same transaction using a two- phase commit protocol. Backup & Recovery Oracle provides industrial strength support for on-line backup and recovery and good software fault tolerance to disk failure. Portability Oracle is ported to more platforms than any of its competition Version Changes Oracle seem very good at informing you in detail as to what is not going to be supported in the next major release.

  Oracle Database Security •Major 4 security measures Automatic Secure Configuration New Password Protections Encryption Enhancements Directory Security Enhancement When you create a new database, you can use Database Configuration Assistant (DBCA) to automatically create a more secure configuration in releases of Oracle Database. Te utinam debitis consequuntur mea, posse debitis electram vel at, sumo affert meliore nec ei. Password complexity verification ensures that users set complex passwords when setting or resetting passwords. you can use Oracle Data Pump to compress and encrypt an entire dump file set. You can optionally compress and encrypt the data, metadata, or complete dump file set during an Oracle Data Pump export.
