1.Define database and DBMS 2. State the importance of DBMS 3. Plan and design a database 4. Identify database objects 5. Appreciate the importance of a database by giving examples.
Database Management System – is a software tool that lets you create, maintain, and summarize an information database. Database – is a collection of related information about a particular person, place or thing. Relational Database – A collection of individual tables holding discrete subsets of information that are linked by common data fields.
ADVANTAGES OF DBMS 1. Fast 2. Compact 3. Flexible DISADVANTAGES OF DBMS 1. Too easy to access 2. Unpredictable Lifespan
Planning a database 1.Know the purpose of your database 2.Gather all reports you will need for a database 3.Make a list of important fields you wish to include in your application 4. Check each field 5. Share common fields of your tables 6. Design and create tables

Database Objects are the different items that make up a database such as tables, forms, queries and reports Table – is an access object that is used to collect data relating to a particular subject Record – is an individual entry in a table. Field – is a piece of information in a record.
Query – is a question you ask your database Dynaset – a list of records matching the query parameters. Form - enables you to view one record on the screen at a time and to customize the display of that record. Reports – used to present table data in a polished format on the printed page. Macro – you can automate frequently performed procedures.
Projects- are access front-ends or conduits to powerful SQL databases maintained on a server running Microsoft SQL server. Database Wizard – Access provides several templates for creating new database files, and the database wizard walks you through the process of creating objects, such as tables, for the new database.
