Microsoft Access / Data Manipulation Queries are the stars of Microsoft Access. Queries make sense out of all the thousands of jumbled records and display exactly what you need to know. Queries discover things like what the average price of tea in China is or which customers bought the most parakeet food from your company. Queries can even make widespread changes to the records in your database without wearing out your mouse and keyboard! For example, a delete query can automatically delete a whole bunch of records that meet your criteria. Site: www.brainbell.com

Microsoft Access / Data Manipulation We have used the concept of a query so far only to create a list of fields that would be considered for a set of records. We also mentioned that a query in Microsoft Access is simply a means of visually representing data. Indeed, a query is based on a SQL statement. As SQL is its own, fully functional language, we can use it to perform far more operations than to only select columns for a query. Site: www.functionx.com

Microsoft Access / Data Manipulation So far, to create a query we have learned to use either the Query Wizard or the Design View of a query. In both cases, we were selecting fields and adding them to the query. This concept of building a query is based on the Structured Query Language abbreviated SQL. In fact, all queries are based on SQL and this language is used by most database development environments, including Microsoft Access. Site: www.functionx.com

Microsoft Access / Data Manipulation Starting a database from scratch allows you to create and add its different parts as needed. When using this process, the main advantage is that you will exercise as much control as possible on your database because you will be creating all of your objects. Site: www.functionx.com

Microsoft Access / Data Manipulation As a database is expanding, so are its objects. For example, many of the tables created by the Database Wizard lack some fields that otherwise would not suit a particular scenario. Site: www.functionx.com

Microsoft Access / Data Manipulation So far, to get acquainted with database fields, we have used two techniques of creating a table and some techniques of adding fields to a form. One of the techniques we used, the Datasheet View, provides a very simplistic way. The Datasheet View is mainly used to perform data entry or to test some fields. Site: www.functionx.com

Microsoft Access / Data Manipulation In everyday life, an object is an entity that displays or provides some characteristics that set it apart. These characteristics are used to describe the object. For example, an object called Car has such characteristics as its make, model, color, year made, price, and mileage, etc. When put together, these aspects can be used to get good knowledge of what the object looks like and perhaps how it functions. The same concept is used in computer programming, in database development, and in Microsoft Access. Site: www.functionx.com

Microsoft Access / Data Manipulation This tutorial covers what many people agree is one of the most difficult database conceptshow to create and work with . A relational database contains two or more tables that are related to each other in some way.For example, a database might contain a Customers table and an Invoices table that contains the customer's orders. In this tutorial you will learn how to link tables in an existing database together in a one-to-many relationship to create a relational database. You will also learn how to enforce referential integrity between those tables to keep records in related fields valid and accurate. Site: www.brainbell.com

Microsoft Access / Data Manipulation Stop typing lists of information in Microsoft Word or Excel! In this tutorial, you will learn how to create databases that can store names, addresses, and any other type of information that you can think of. You will be pleasantly surprised to find that creating a database isn't all that difficult. Microsoft Access even comes with a Database Wizard that takes you step by step through the process of creating a database. Site: www.brainbell.com

Microsoft Access / Data Manipulation When creating relationships among tables, we were selecting the primary key of one table and the foreign key of a dependent table to join them. Once such a relationship is created, you can create a query that combines both tables to create a set of records, also called a record set, or a Recordset, that would include either all records or isolate only the records that have entries.

Microsoft Access / Data Manipulation Data analysis provides the user with the ability to examine a database's records and the overall behavior of its objects. Data analysis is performed on tables, queries, and/or forms. There are two main aspects involved with data analysis: what you provide to the users and what the users may decide to do with data at their disposal. An intermediate to advanced user of Microsoft Access will know how to perform some, most, or all of the operations we will review. Site: www.functionx.com

Microsoft Access / Data Manipulation Most of your data entry will be performed on forms. This is done to protect your tables from (even unintentional) corruption. This means that, during table design, you should be aware of what table is doing what and why. Site: www.functionx.com
