Oracle first introduced its Big Data Appliance as well as the NoSQL database at the company's OpenWorld user conference last October. According to analyst David Menninger of Ventana Research, the appliance was created to manage and analyze data sets deemed to be too large for storing in standard databases. The Big Data Appliance boasts a lineup including Sun server hardware (18 Linux-based x86 Sun servers with 216 processor cores, 648TB raw disk storage, 864GB working memory), Oracle NoSQL database, Oracle's Java HotSpot Virtual Machine, and an open-source distribution of R.

Headlining PeopleTools 8.52's list of improvements is support for Apple's popular iPad tablet. The move makes Oracle the lone enterprise resource planning vendor to provide an enterprise suite on the iPad, giving users the ability to access PeopleSoft on the go while maintaining the functionality and security one would normally expect in a stationary setting. While iPad support is appealing, it's just the tip of the iceberg when it comes to PeopleTools 8.52's enhancements. The user interface has been upgraded to improve interactivity through the use of new pagelets and inter-pagelet communic...

The highlight of the latest update includes a number of statements marked as unsafe for statement-based replication. According to the H Open website, all of the statements given the distinction of being unsafe supposedly rely on the result of a select statement where the order cannot be relied upon. Oracle recommends that any users who engage in statement-based logging should read the accompanying documentation for additional guidance regarding the issues addressed in the update. Beyond the replication issue, Oracle also used MySQL 5.5.18 to fix a problem where the master could send dama...

In addition to the NoSQL Database release, Oracle also announced that its highly anticipated Big Data Appliance would become available during the first quarter of 2012. Oracle initially gave a sneak peek into both products at the Oracle Open World Conference in San Francisco a few weeks ago, so the rather quick availability and updated information show that the company is taking aggressive steps to measure up to the competition. The timing of Oracle's announcements could not be any better, as its competitors are also making moves in the large-scale data processing arena. EMC and IBM kicked t...

How to sort a result set by an alias, an expression, or a column number Figure 3-18 presents three more techniques that you can use to specify sort columns. First, you can use a column alias that's defined in the SELECT clause. The first SELECT statement in this figure, for example, sorts by a column named address, which is an alias for the concatenation of the vendor_city, vendor_state, and vendor_zip_code columns. Within the address column, the result set is sorted by the vendor_name column. You can also use an arithmetic or string expression in the ORDER BY clause, as illustrated by the s...

How to use the LIKE operator One final operator you can use in a search condition is the LIKE operator, shown in figure 3-15. You use this operator along with the wildcards shown at the top of this figure to specify the string pattern, or mask, that you want to match. The examples in this figure show how this works. In the first example, the LIKE phrase specifies that all vendors in cities that start with the letters SAN should be included in the query results. Here, the percent sign (%) indicates that any characters can follow these three letters. So San Diego and Santa Ana are both include...

How to use scalar functions Figure 3-7 introduces you to scalar functions, which operate on a single value and return a single value. These functions work differently than the aggregate functions described in chapter 5 that are used to summarize data. For now, don't worry about the details of how these functions work, because you'll learn more about them in chapter 8. Instead, just focus on how they're used in column specifications. To code a function, you begin by entering its name followed by a set of parentheses. If the function requires one or more parameters, you enter them within the p...

How to code string expressions A string expression consists of a combination of one or more character columns and literal values. To combine, or concatenate, the columns and values, you use the concatenation operator (||). This is illustrated by the examples in figure 3-5. The first example shows how to concatenate the vendor_city and vendor_state columns in the Vendors table. Notice that because no alias is assigned to this column, Oracle assigns a name, which is the entire expression. Also notice that the data in the vendor_state column appears immediately after the data in the vendor_city...

How to code the SELECT clause Figure 3-3 presents an expanded syntax for the SELECT clause. The keywords shown in the first line allow you to restrict the rows that are returned by a query. You'll learn how to code them in a moment. But first, you'll learn various techniques for identifying which columns are to be included in a result set. How to code column specifications Figure 3-3 summarizes the techniques you can use to code column specifications. You saw how to use some of these techniques in the previous figure. For example, you can code an asterisk in the SELECT clause to retrieve all...
