Why save it already? Because data such as records will be saved automatically as it is being entered into a database.ĭatabases do not use files in the normal sense, however a good database can output its content structured with SQL (Structured Query Language) – an ANSI/ISO standard. For now, use OpenDocument Database format, though this will probably be already automatically selected as the default. Don't choose the Table wizard just yet and save (and name) your database in a convenient location. Choose to register the database, don't worry this is only done locally and can help other modules of (such as Calc) work with your database. Choose Create a Database to begin with and click Next. On launching Base you are presented with a Database Wizard which offers you the choice of creating a database, opening or connecting to an existing one.
How to use openoffice database software#
Wizards are simply a way of describing a step-by-step approach in making software easier for the user, usually choosing an option and clicking Next. When you specify the relationships between tables you can also specify referential integrity so that data can't be entered which contradicts related data in another table. These can be one-to-many relationships or many-to-many relationships. The difference between databases and spreadsheets is that while spreadsheets can contain records (often a row in a spreadsheet) and data fields (which is just a particular type of data - often a column header in a spreadsheet), databases can also contain relationships between records. In situations such as this, you are better off using a database rather than a spreadsheet. You could use a spreadsheet with one order per row, but you may have to type in customer name and address repetitively for many orders. You could use a spreadsheet with one customer per row, but one customer might order many products.
Imagine you want to record the products that customers order from your company. There is limited support for Microsoft Access databases. If you have an existing database already created, you can connect to it either with the first screen you see in Base or by clicking File, New, Database then Connect to existing Database. In large systems, a DBMS allows users and other software to store and retrieve data in a structured way.Ĭonnecting to Databases DBMSes may use any of a variety of database models, such as the network model or relational model. The model in most common use today is the relational model.Ī database management system (DBMS) is computer software that manages databases. The structure is achieved by organizing the data according to a database model.
A database is a structured collection of records or data that is stored in a computer system.
